It took Harry quite a few minutes to have Nel calm down, but after he did, Ichigo, Rimuru, and he took her and the other arrancar that came with Nel to the Kurosaki household to talk more about this, clearly, there was something happening but they needed all the details before anything can be done, so a talk was necessary.
Once everyone arrived in Ichigo's room, Pesche, the other arrancar who arrived with Nel and was the one Ichigo was stepping on, told Ichigo, Harry, and Rimuru of what was going on, appearantly, someone had been attacking Hueco Mundo and they had kidnapped Tier Harribe, who had become their leader in Hueco Mundo after the fall of Aizen.
The news left Ichigo stunned and Harry utterly surprised, they both knew how powerful Tier was, Ichigo heard firsthand how powerful she was, while Harry fought against her and the other Espada to hold them back until Ichigo arrived to help.
So the fact that someone attacked Hueco Mundo and was able to defeat and take Tier was still a surprise, Harry sighed and shook his head, "Someone was able to fight off the Espada and kidnap Tier?... she's quite powerful, so how? it almost sounds like a lie...".
Pesche who was sitting on the ground in Ichigo's room, nodded, "But it's true, after the deaths of Lord Barragan and Lord Stark, Lady Harribel has been the ruler of Hueco Mundo.
But she..." Apparently, Tier and the other arrancars fought as best as they could but were overwhelmed by the powers the enemy used against them, Harribel had been violently defeated and quite a few arrancars were killed.
Seeing this Harribel didn't hesitate to tell Nel, Pesche, and Dondochakka to run away, having no other choice and unable to fight, these three ran away as fast as they could, as they got away, Pesche watched as Tier was shrouded in shadows and then disappeared soon after.
Pesche just knew that she was taken somewhere else but no one knew where, "We have no idea why they took Lady Harribel...".
Nel, who was hugging Rimuru in his slime form as a sort of stress ball, suddenly began to cry and hug Rimuru very tightly, "Gack!".
While Rimuru was being tortured by hugs and his body being warped into an odd shape, Nel began to sob and then spoke, "I can't believe they got Lady Harribel!".
Nel suddenly let go of Rimuru as she cried, allowing the slime to breathe easy and then reform his now warped and out-of-shape body, though he asked a question as he did so, "Do you know who they were or what they were after?".
Pesche sighed and then shook his head, "We don't know... but we're positive that they've taken several arrancars and while we were trying to escape, they cornered us and nabbed Dondochakka!".
Pesche suddenly dropped on all fours in front of Ichigo and Harry surprising both of them, Pesche then wasted no time in making a request, "Ichigo Kurosaki! Harry Potter! Please help us!".
Pesche held his head down and waited for Harry's and Ichigo's answer, until Harry suddenly spoke up, "I'll help, there's no way I can ignore this".
Ichigo nodded and said, "Me too! After they told us, I can't just ignore them".
Pesche looked up with wide eyes full of surprise, "Ichigo Kurosaki! Harry Potter!".
Nel looked up as well and smiled a bit, "G-guys...".
Harry suddenly shook his head and then turned to look at Ichigo, "I need you and the others to stay here and keep an eye on the city"
Ichigo widened his eyes in shock at Harry's sudden request, "What!? What do you mean stay here!? I can't let you just go into Hueco Mundo alone! Are you crazy or did you forget what we went through the last time we went there!?".
Harry chuckled and then smiled at his brother in all but blood, "You forget I'm not the same Harry I used to be Ichigo, plus, I think I know what's going on".
Everyone turned their heads towards Harry surprised that he might know something about the situation, Ichigo looked at him for a few seconds and then asked, "Well? What's going on then".
Harry sighed and then said the one thing that made Ichigo very nervous, "I got a quest when I was in Soul Society, one that told me of a few things that make me believe that this attack in Hueco Mundo is connected to a bigger problem".
Ichigo winced and took a step back, the substitute shinigami knew that when Harry got a quest, there was something very serious going on, especially now that he knew that the quests had always been chosen and sent by none other than Death herself.
So if Harry was telling him to to stay here in the real world and keep an eye on things, then things are either, very serious or annoying to deal with, "Fuck... alright, I'll contact the others and keep an eye on the city".
Harry smiled at his friend and then nodded, "Good, and don't worry, I'm not going to Hueco Mundo alone, Rimuru is coming with me and you know he's not someone to mess with".
Ichigo sighed and nodded, "Yeah I know, still... be careful Harry, every time you got a quest before, we always ended up in far much bigger trouble than usual and that's saying a lot".
Harry chuckled and shook his head in amusement, "Don't remind me".
Both substitute shinigami and dragon god shared a laugh while everyone just stared at them in amusement, after that Harry got ready to leave, while Ichigo went to gather everyone to keep the city safe.
Pesche and Nel stayed behind to go with Harry since they had to go back to Hueco Mundo anyway, an arrancar shouldn't be staying in the real world for too long after all.
~A few minutes later, in Hueco Mundo~
Harry opened a dark corridor in Ichigo's room and once everyone stepped through they found themselves in the sand dunes of Hueco Mundo, Harry and Rimuru immediately sensed something going on which made them stop a second and narrow their eyes, "Rimuru, did you feel that?".
Rimuru nodded, "Yeah... what is that energy signature? It's not coming from a hollow or an arrancar, I felt those types of energy on you before, but these ones are new".
Harry nodded and frowned, "Yeah... those are quincy energy signatures, so you wouldn't know how those energies feel, they're supposed to be all gone except for Mom, Yuzu, Uryu, and his father".
Rimuru turned into his human form shocking both Nel and Pesche, the demonlord narrowed his eyes and frowned as well, "So this Quincy King really is involved here... you were right, this does have to do with your quest".
Harry nodded and then turned his head towards Nel and Pesche, "Alright you two, we'll be moving up ahead to check things out, I want you guys to stay out of sight and be careful, I have a feeling that things are going to get violent and fast".
Both Nel and Pesche nodded, both arrancars looked nervous but they also trusted Harry to protect them and help their fellow arrancars as well, so they were going to make sure to stay out of the way.
With that decided, Harry and Rimuru took off flying, while Pesche and Nel used their super speed to follow and keep up.
It didn't take long for the dragon god and slime to arrive high above the sky of Las Noches, both quickly looked down and watched what was happening right now, to Harry's surprise, quincies were forcing a group of arrancars in chains to walk forward, "Come on! Don't stop! keep moving!".
Harry frowned and immediately headed down, with Rimuru following close behind, suddenly one of the quincies stopped and looked around, "Huh? Where is that odd sound coming from?".
Another quincy stopped and asked his fellow quincy a question, "What's wrong?".
The quincy that stopped frowned before answering the other quincy's question, "You can't hear that? It's sound like a low humming sound".
The other quincy shook his head and then said, "It's probably nothing, everything here is dead after all".
The quincy that heard the humming sound nodded and then everyone kept moving, meanwhile, Harry and Rimuru were looking at a battlefield not that far behind the quincies and shackled arrancars.
Rimuru huffed and shook his head upon seeing the death and destruction, "Sheesh, they killed them all".
Harry nodded, as the Master of Death, he isn't really fond of Hollows, especially since they feed on souls, but arrancars are different, they're sentient and no longer need to feed, so seeing so many dead was annoying to see, "I'm just glad we told Nel to stay a bit behind, I wouldn't want her to see this".
Rimuru nodded in agreement and then turned towards where the quincies were heading, "Come on, let's follow them and see what's going on".
Harry nodded and stood up, "Yeah, whatever they're up to with those arrancars can't be good".
Both slime and dragon god nodded and then disappeared in blurs of speed as they followed the quincies and arrancars from a long distance.
~Some minutes later~
Eventually, the quincies stopped and one of them lined up the arrancars, while another began to loudly speak to them, "Get in line! Stand with your back against the wall!".
Another quincy then began to loudly yell at the arrancars as well, "Hurry up! We don't mind punching two or three holes into you!".
Nearby, another quincy was quietly sitting on a white throne while watching his subordinates organize the arrancars, this quincy is known as a stern ritter by the name of Quilge Opie.
Some of the arrancars noticed him and one of them began to whisper to the ones beside her, "That guy seems to be their leader...".
One of the other arrancars nervously asked, "Hey, are we really doing this? Perhaps we shouldn't...".
The arrancar who noticed the guy sitting on the throne frowned and immediately responded, "Idiot if we don't do anything, we'll just end up dead anyway!".
The other arrancars quietly nodded, but before they could continue their conversation, someone loudly began to speak, "Attention, attention! Quiet, please! We'll decide which arrancars live or die here now!
We'll be having a selection competition for the hollows and arrancar! So I will be... stabbing everyone, starting for the right side! So if any of you are thinking, 'No, I don't want to die!' or, if any of you are thinking, 'Please! Let me join you!'.
Then please get down on your knees and beg like you are licking our shoes! All of you are the chosen few who had the luck, wits, and strength to survive our attack earlier! Please don't waste this opportunity!"
One of the arrancars stepped a bit forward and asked a question, "If I say I'll join you, will you spare my-".
Only to be stabbed by a spear from Quilge Opie who was the quincy talking right now, the arrancar didn't even have to grunt in pain before he was slammed against a wall and killed on the spot.
Meanwhile, Quilge Opie dramatically turned away and spread his arms wide open, "No! Of course not! Those of you who wish to apply must take the entrance exam! This selection event will decide who gets the opportunity to take that test.
Those of you who don't understand my explanation will end up... like this!".
Quilge Opie pulled his spear out of the now-dead arrancar and then quickly stabbed another arrancar through the abdomen, he continued to do this again and again while having a maniac smile on his face.
One of the quincies behind Quilge Opie, suddenly spoke up, "Does the Captain really have any intentions of bringing back any arrancar?"
The quincy behind him slightly shook his head and said, "Not at all, he's not interested in Hueco Mundo, to begin with".
Meanwhile, Quilge Opie continued to kill arrancars left and right, "That is how you'll die!".
When Quilge Opie pulled his spear back to stab another arrancar, the arrancar reacted quickly and moved away while placing the cuffs on her arm in the spear's way, the weapon hit the cuffs and chain destroying them and setting the arrancars free, one of them immediately drew her sword and placed the tip right against Quilge Opie's neck.
The quincies behind Quilge Opie immediately reacted and called out to their Captain, but Quilge Opie didn't seem to care about the sword's tip right against his neck, instead, he said, "Your response time before saying 'Captain' was too slow, how strange".
Quilge Opie tilted his head as he stared down at the arrancars who were able to get free from their shackles, "I thought we confiscated all of their Zanpakutos".
The arrancars who set themselves free pulled their robes off of their bodies and revealed themselves as two female arrancars, one of them had black hair tied in twin ponytails and immediately introduced herself as she glared at the quincies, "Lord Aizen's aid, Loly Aivirrne!".
The other Arrancar, who had short blonde hair then said, "Likewise, Menoly Mallia!".
Loly snarled at Quilge Opie and angrily shouted at him, "Don't assume we'd be defeated by an underling like you!".
Quilge Opie just calmly stared at Loly and Menoly, unnoticed by the female Arrancars, Quilge Opie's quincy cross began to glow, and in an impressive display of high speed, the stern ritter attacked Menoly and Loly, stabbing two reishi arrows into Menoly's shoulder and backhanding Loly to the side when she tried to stab him.
Both defeated arrancars now lay on the ground while Quilge Opie turned around and began to walk away, while doing so he then called out to the quincies who stood behind him, "Do it".
Both quincies saluted and responded right away, "Yes sir!".
Other quincy then asked, "Should we kill them?".
Quilge Opie smiled and then said, "No, his majesty ordered us to bring him any idiots with guts, those two have passed, however, the fact that Aizen would appoint such weak arrancars as his aids show he's not that great".
As Quilge Opie walked away talking to himself, the quincies began to mercilessly beat up both Menoly and Loly, their grunts and screams of pain echoed through Hueco Mundo, meanwhile, Quilge Opie continued to speak to himself, "Then again, even Tier Harribel who ruled Hueco Mundo after the late Aizen, was no match against his majesty, so I shouldn't be surprised".
However, a loud slashing sound and a grunt of pain caused Quilge Opie to stop walking and turn around, "Hey, I told you not to overdo i-".
Only to stare as a few of his fellow quincy began to fall dead attacked by something moving at high speed, whatever it was it was also coming towards him, but the stern ritter easily caught the object that killed many of his fellow quincies with one hand.
Quilge Opie looked up and frowned, "Mind telling me who you are?".
Above the stern ritter, standing on a big piece of rubble, are three other female arrancars, one of them, a black-haired one, smirked at Quilge Opie and then loudly said, "Huh? You dare speak poorly about Master Harribel, and yet you don't know who we are!? I guess you underlings really are clueless!".
Another one of the arrancars, this one with long black-haired and wearing big sleeves spoke up next, "It seems you took Master Harribel while we were away".
The last arrancar, a tall muscular one, with brown skin spoke up next, "Don't get cocky just because you defeated those self-proclaimed aides to Aizen!".
These three arrancars are Mila Rose, Sung-Sun, and Apacci, three powerful arrancars known as the Tres Bestias, Quilge Opie just calmly listened to what the arrancars said and then smiled.
~Meanwhile~
Harry and Rimuru were flying towards where the spiritual pressure of the quincies and arrancars stopped, only to stop when a big explosion went off, Rimuru whistled and then said, "Whoa, looks like the fighting started already".
Harry stopped as well and floated to Rimuru's side, "Yeah, there's a lot of quincies there's but they're being quickly taken care of by three other arrancars, these ones quite more powerful than the others but...".
Rimuru frowned and nodded, "Yeah, they're no match for that big quincy energy signature there, we should keep going and go faster this time, I have a feeling that things are about to get bad for the arrancars again".
Harry nodded, a second later both slime and dragon God took off flying towards where the fighting was taking place.
~Back with the Tres Bestias~
The three female arrancars were not having any trouble killing quincies left and right with ease, none of them could measure up to arrancars of their power level, though Quilge Opie just sat there and watched the battle go on, "Impressive...".
Thinking that Quilge Opie was distracted, Sung-Sun snuck up behind him and then whispered to him, "You shouldn't be looking away".
Sung-Sun wasted no time in attacking the stern ritter, but Quilge Opie reacted right away and dodged all her sword slashes with ease, he even had the gal to speak while doing so, "I gave a suggestion, surrender".
Sung-Sun narrowed her eyes, which only made Quilge Opie smirk, Mila suddenly jumped up and then came down while swinging her sword downwards and toward Quilge Opie, "Are you stupid?".
Before the stern ritter could even say anything, Mila attacked him in full force, causing the ground to tremble and the sand of Hueco Mundo to be spread all over the place.
The Tres Bestias all jumped back and landed beside each other, while Apacci grinned and yelled, "You're not as strong as you claim!".
To their surprise however, Quilge Opie continued to calmly speak, completely unharmed by Mila's attack, "If you surrender and join our banner, you'll be able to work for his Majesty along with your beloved Tier Harribel, you will never get to experience greater happiness, now or ever!".
The Tres Bestias frowned, until Apacci suddenly punched Quilge Opie's throne and destroy it, all three female arrancars then spoke up at the same time in anger, "Don't underestimate us, you damn four-eyed monkey!".
Quilge Opie tilted his head and looked confused, "Oh my, have negotiations fallen through? How extremely disappointing...".
Quilge Opie and the Tre Bestias then launched toward one another, ready to kill each other if necessary, explosions and massive blasts went off on the battlefield, but it was soon evident that the Tres Bestias were losing ground against Quilge Opie, it was only a matter of time before they were defeated.
It took Harry and Rimuru a few moments later to arrive, the very nature of Hueco Mundo was a state of constant Flux, which made traveling across this dimension difficult, even for beings like Harry and Rimuru, resulting in a few minutes delay, but it was enough time for Quilge Opie to defeat the Tres Bestias.
So when both dragon god and slime arrived, they found the three powerful arrancars on the floor, defeated and completely covered in wounds, Quilge Opie who was standing above the Tres Bestias turned his head towards Harry and Rimuru and smiled at them.
Harry narrowed his eyes at the quincy the moment he saw his arrogant face, "Alright, I don't know you, but I can tell right away that you're an asshole".
Rimuru nodded, "Yeah, that ugly mug of yours is disturbing enough as it is, having it smiled at you just makes it worse".
Quilge Opie didn't stop smiling but he did narrow his eyes upon hearing Rimuru and Harry's comments, "... You're not hollows, nor arrancars, who are you, And what are you doing here?".
Harry smiled, "Oh? You don't know about me? Didn't your so-called quincy king spy on the happenings of Soul Society and Hueco Mundo some time ago? Don't tell me he didn't tell you about me".
Quilge Opie suddenly stopped smiling and stared at Harry, "Harry Potter... I see, so you have come back, what timing, just in time to witness my Majesty's plans come into fruition!".
Rimuru sighed and shook his head in exasperation, "This guy is so full of himself, how cringe".
Harry nodded, "He really believes he's stronger than us and has nothing to worry about".
Quilge Opie ignored Harry and Rimuru's words and then said, "The daten that His Majesty gave us included information about you.
You were listed as a unique threat, one that we should prioritize dealing with!".
Quilge Opie raised his hands and a few quincies appeared above him in blurs of speed, Harry just raised a hand and said, "Unique threat? Well, I wasn't anything too special back then, so I can't blame your King for not being that worried about me... let's change that shall we?".
In a flash of blacklight, Oblivion appeared in Harry's hand as the quincies moved to attack him and Rimuru, the demonlord narrowed his eyes as the quincies began to blur in and out of sight, "This technique must be the hirenkyaku, right?".
Harry closed his eyes and nodded, "Yes, but this level of speed shouldn't be a problem for you, right Rimuru?".
Rimuru grinned and nodded, as the quincies summoned their glowing reishi bows and got ready to shoot both Harry and Rimuru, the demonlord suddenly raised a hand, which began to spark with black lightning, "Kuro Ikazuchi!".
The quincies' eyes widened when massive black thunderbolts began to lash out from Rimuru's hand, taken by surprise by the demonlord's spell, the quincies didn't have time to move out of the way and were instantly disintegrated by the black lightning.
Quilge Opie covered his face with his arm and watched in shock as a single attack killed many of his fellow quincy in a matter of seconds, "What! What sort of attack was that?! I didn't sense any spiritual pressure in it".
The black lightning soon stopped lashing out and then began to calm down until it dissipated in Rimuru's hand, Harry just grinned at the stern ritter and said, "What? Didn't you king tell you we can use magic? Don't tell me he couldn't recognize what it was? So much for the all seeing and all powerful quincy king".
Quilge Opie glared at Harry and summoned his saber, his weapon began to glow with blue reishi and then shot a massive beam of reishi at Harry, the dragon god just smiled at such a weak attack as Quilge Opie growled in anger, "Don't speak about my Majesty with such disrespect!".
Harry just scoffed and swung Oblivion right as the blue beam of reishi was about to collide against him, Oblivion easily slapped the attack away and sent it flying over Harry and Rimuru, until it crashed against the dunes of Las Noches and violently exploded.
Quilge Opie just scowled as he watched his attack fail while Harry just looked down at him, "Your King is just a senile old man who thinks that he's better than anyone else and more powerful as well when in reality, he doesn't even measure up against some of the foes I faced, he's just a child angry at daddy for being denied what he wanted".
Rimuru chuckled and then smirked, "Ah, all of this is just a child throwing a temper tantrum huh? How lame!".
Quilge Opie roared in rage and swung his saber towards Harry, firing a row of blue reishi projectiles at both slime and dragon god, Rimuru just raised his hand and then said, "Beelzebub".
Black matter rushed out from Rimuru's hand and intercepted the reishi projectiles, devouring them in seconds, Rimuru then smiled as Ciel suddenly spoke up in his mind [Analyzing technique... copying method of creation, creating new skill, success!
New Skill Acquired! Spirit Arrows! By copying a quincy's method of harnessing, manipulating, and controlling spiritual particles in the air, one can then shoot a spiritual projectile, which causes both spirit and soul damage].
Rimuru smiled and nodded, "Thank you, Ciel".
[You're welcome.]
Harry looked to his side and noticed Rimuru's smile, "Looks like you were able to copy the technique"
Rimuru nodded and pointed a hand towards Quilge Opie, "Yeah, though I use spiritual particles instead of reishi, after all, that's a type of energy that doesn't exist in my world, but Ciel was able to make it work, let's see how strong it is! Spirit Arrows!".
Quilge Opie's eyes widened as Rimuru suddenly fired a barrage of what seemed to be black reishi arrows, and a big explosion soon went off the moment Rimuru's new skill crashed in Quilge Opie's location.
Harry nodded and then commented on the Skill, "Not bad, at least B tier in power, plus I could see that it has some extra effects as well".
The explosion soon subsided and dissipated, revealing a thoroughly pissed-off Quilge Opie, who was glaring at Rimuru, "You dare imitate our techniques! The gifts granted to us by our Majesty?!".
Rimuru just shrugged, not at all caring for the anger displayed by the stern ritter, "Dude, that technique of yours isn't that special, I've seen more than enough fighters able to harness the energy around them, get off your high horse, your king and you guys aren't that special".
Quilge Opie scowled and looked like he was going to say something, but he suddenly stopped and looked to the side, Harry raised an eyebrow at that and frowned, "Looks like he's receiving some kind of communication".
Rimuru nodded having noticed the same thing as Harry, "Telepathy most likely".
Quilge Opie soon smiled and stood up straight, "Looks like my Majesty has granted me permission to go all out! Prepare yourself! For you're about the witness a quincy's final state, Letz Stile!".
The stern ritter raised a hand and took off his white glove revealing a black one with a quincy's cross in the back of the hand, the cross began to glow as Quilge Opie smirked in victory, only for his eyes to widen in shock a few seconds later as his entire arm was cut off by Harry, who moved in a flash of twilight and cut it off before his grand attack could fully activate, "W-what?...".
Harry reappeared behind Quilge Opie and shook his head, "You must think I'm stupid if you thought I was just going to let you charge up whatever you're planning, I know from experience, never to let a quincy prepare".
Harry has fought and sparred with Uryu plenty of times, so he knows not to let a quincy have time to prepare since they can pull off some very nasty surprises, "And now we also know that your King is watching us right now, thank you for the information".
Quilge Opie stared down toward his arm, which had landed on the ground not too far from him, he was in complete shock at what happened and how fast it did so, "This wasn't supposed to happen...".
