HIRO POV
"Whoa. Guess this is the place where I train when I fell asleep huh?" I mutter as I am in a wide room as information enter my head explaining what I can do in this room.
"Hmm. I need to start to create attacks from my Dragon Slaying Magic. And I need to familiarise myself with the inheritances. Guess for 8 hours I will just get used to all the powers I have. Hmm. Or I can just focus on one magic first. Right now Lightning Dragon Slayer Magic should be my priority. It is based on speed. Purgatory meanwhile should be the tank and wide-area attack in case I want to annihilate my enemies. Purgatory or Lightning? Hmm." My brain seems to be thinking many advantages and disadvantages at a very fast rate due to my thought acceleration.
"Hmm. I will spend 4 hours practising Purgatory First. And the remaining hours will be the Lightning One. The inheritance can come later since those can be practised easily with the memories that of the characters that come when I get their inheritance. My biggest hurdle and challenge is the Dragon Slaying Magic." I said as I closed my eyes feeling the Red Lacrima that hold the Purgatory Dragon Slaying Magic.
I approach it as the mana or magic energy around me start to swirl around it and my stomach feels warm as I guided it through my whole body. My body feels warm as both Dragon Lacrima now are active and available for me to use.
"My magic capacity is still unknown. Let's just practice the magic first to get the feel to use it." A red magic circle appears on my right hand as I marvel at the sight of it.
I mean the Install pretty much shock me as I become like a superhuman back there to kill their Fallen Angels except one.
Sona must want to bring this up to her sister for her to give a warning toward the Fallen Angels to not infiltrate this town anymore.
Hmm. Though I did not know how long will that Fallen Angel last. I mean Gáe Buidhe delivers an injury that cannot be healed with magic.
Oh well, not my concern.
I imagined the fire on my right hand enveloped my right fist but the fire burst out that make me to fell on my butt.
"That did not go well. At least I know my head did not suffer any injury because of that." I thought in my head as I focus on the fire to envelop my fist.
A mannequin of wood appears as I maintain the flame as I hoot out my attack.
"Purgatory Irom Fist." I punch the mannequin that gets destroyed as the fire disperse after that.
"Hmm. That is not bad. But I need to create more spells." My mind starts to think of the attacks I can make, the simple ones that start from the basics by throwing a fireball and spit out fire from my mouth.
I just focus on the basic attacks which are
Purgatory Dragon Roar-this attack makes me unleash a torrent of fire toward my enemy. This attack is the best one to attack my enemy from far or to spew it around the venues that surrounded me.
Purgatory Iron Fist-This is my favourite one as I can use both of my fists to deliver this attack toward my enemy anytime as I want. I also can charge this attack by compressing the fire on my fist to make it more impactful than before. But I need to practice this attack more since I want this attack to break anything my fist hit.
Purgatory Talon. The kick attack that functions is the same as Iron Fist though this one can be used in combo to pummel my enemy many times.
Purgatory Wing. This one is tricky as this one is a shield and also a blade. I can just tackle through my enemy with this attack and swipe away them too.
Purgatory Bullet. This one is inspired by Ace's Higan where I focus on small orbs of fire that can be continuously shot toward my enemies not giving them a chance to counter.
And lastly Purgatory Wall. This one is a firewall that can be shaped after I used my Purgatory Wing to form a broad wall in front of my enemy. This can chase my enemy to focus on breaking this wall.
Those are some moments I made which is not much as they are many more but 4 hours have passed as I then convert these attacks to my Lightning Dragon Slayer Magic.
But this time I have the element own attack which is to become a living taser when the enemy is near me though this will be caused my nearby allies to be tasered too.
That should be my trump card. As for the volt, I know my volt is the same amount or higher than Denki Kaminari.
Wait a minute the lightning Dragon Slayer has broadened my vision to create some of the movement that I cannot wait to recreate as some cannot be used when I used Purgatory.
Lightning Laser. This one is a simple old attack but also deadly. Against normal humans, it can tear limbs easily but against the supernatural beings, I need to increase the input of lightning in my attack.
Lightning Claws. This one formed many claws that I can see to slash and stab my enemies. But I also focus on paralysing my enemy.
Lightning Speed. This one is tricky as I am currently practising it.
"Ouch." I rub my head as I am stable against hurdles that I place randomly as I need to get used to this kind of speed.
Hmm. Wait a minute this movement also can be used in Purgatory. Does Natsu already have this movement where he became like a rocket to blast himself forward?
Seriously just practising these 2 magic with the help of thought acceleration made me feel elastic about how terrifying to have a smart brain.
And my Otaku knowledge. I already picture myself piercing my enemy with Chidori. And spit out a wave of flame using Purgatory as Madara does in the War.
Hmm. I already know what I am going to do after this.
I am going to join Sona's peerage. I mean there are many, not so many Self Inserts like me to join her peerage.
All of them want to join Rias to be in the MC plotlines.
Hmm. But still, Sona's peerage is not that bad. Though I need to brace myself to tell her what am I. For now, she knows I am Diarmuid Ua Duibhne's inheritor which makes her pique an interest in me to make me join her peerage.
Most of all her peerage has the backing of her older sister, Serafall Leviathan who is a magical girl. I already watch though my focus is her sexy body.
Damn. Any man will be lucky to have her.
The dimension then shakes as my time is up with me then open my eyes to see I am in a bed, The King one as I know I probably brought here.
As much as I want to sleep I need to practice my mana.
Hmmm. I already have a plan of how to properly control my mana precisely.
Dragon Slaying Magic attacks can drain my mana, especially powerful attacks but that can. be solved if I eat any fire or lightning around me.
The point is I need to use every single bit of my mana perfectly. I did not want a lame reason of mana lacking to be the reason I lose.
Circulating the mana through my whole body I lay my body and closed my eyes as I aim to maintain it through my whole body though after a minute pass I lose conversation and it disappears.
I keep doing it to the point my mana reserves are close to zero. I waited for about 2 hours as I continued back my training by keep maintaining the mana around my body.
Slowly I make it to my finger, ear, hair, nose and mouth as I keep still of it.
My body which previously is normal right now has mana covering it that glows blue as I try to keep it until morning arrived.
The main point is I will not be like Naruto who likes a lot of chakras but fails to walk on trees and water since he is unable to put the right amount of chakra on his body part to make him stick on any surface.
Putting a lot will make the surfaces crack or the body parts explode from the chakra. Pitting less will make you lose your sticking.
Hmm. Maybe I should try to apply the same training which is sticking leaves on my body part to increase my mana control.
Yeah. That sounds like a good idea for me to practise it.
Right now Issei probably is sleeping while not knowing he already is a devil and become the current Red Dragon Emperor.
Then he will just do the boring stuff by handing the pamphlet.
Yeah. I remember at the beginning his mana. capacity is slow that he cannot teleport to his client house so he needs to cycle there.
What a joke.
I, for now, know I am ten steps ahead in front of him.
This guy only trains when Riser arrives but for me, I will train myself to the point I cannot feel my body as Trihexia will appear tomorrow.
That will be my mindset during my training.
I remember Sona'a dream to build a school for any devils to join. It is a noble dream though not many people supported it since they still look down upon Low-Class Devils and Reincarnated Ones.
I already had a way to support her dream which is to become stronger and create fame throughout the entire Underworld and then the world where many people will become my diehard fans as then my support toward Sona's dream will be followed by them.
Many influences will make Sona's dream achievable.
My eyes then feel heavy as I just surrender myself to fell asleep.
.....
"Hmm. Interesting. His mana capacity is a lot for a normal human." Sona Shitori or Sitri commented as she with her peerage already finish cleaning up the mess and being the remaining Fallen Angel to a place where they detain him for him to spot any information when being interrogated by the helpers from her older sister.
"Kaichou. This is all the information I have gathered for you regarding Hiro Akito." Tsubaki handed a stack of papers that has the story lives of Hiro Akito.
"An orphan who gets found by the caretaker whose orphanage has been brought down. Then he survived on his own. No record of bad behaviours except close ones where he beat some students. Hmm. It seems he is a good student but still many people have false thoughts about him due to his lone wild attitude." Sona said as her brain now is thinking how this student manages to hide his status as the inheritor of Diarmuid Ua Duibhne, a hero figure from Celtic.
"What is your thought about him Tsubaki?" She asks her best friend and Queen.
"He is clean. And he is also quite as fast and strong as a normal human. That sudden power-up he caused must be some sort of trigger for him to do that feat." She replied.
"Yes. That card. I tried to find it but failed. Maybe it fise with him." Sona said.
"Maybe an Heirloom? Or Sacred Gear?" Tsubaki guess as Soma just rub her forehead.
"Whatever. We need to sleep. Our guest fell asleep. I must admit he is quite interesting to circulate his mana like that. Though I think he did not bother to hide it from us." Sona said.
"Do you wish to make him join us?" Tsubaki asks Sona.
"Yes. His potential is high. Let's just prepare ourselves for tomorrow." Sona said.
"We also need to prepare force shock that will come from Rias. She must be shocked to see the normal human she left to do is not normal at all. " Sona continued.
"I understand Sona," Tsubaki said as both girls goes to sleep.
