Chapter 64: Underground Arena in the Underworld
The "Rating Game" was the most popular event in the Underworld.
Everyone sought it, whether it was to watch the famous fighters or to become part of this event.
Everyone wished to be part of it.
Naturally, as the creator of this game, Ajuka Beelzebub got a lot of money from it. Even though he had a laissez-faire attitude toward this game since he had many things that he wanted to do, his team managed all the technical matters on the "Rating Game," including the creation of the field.
This field creation generated a lot of money, and except for a field for the "Rating Game," it could be used as a part of architecture at the house and also as a training field.
It was possible to get them, but as expected, it was expensive.
And the one who mastered this lucrative technology was Ajuka.
Frankly, Ajuka didn't monopolize this technique and shared this technology with others, such as the other Maous and the Great King faction, but as expected, even if they received a share of information, their brain wasn't enough to understand this field creation technology. Moreover, even if they could understand it, there was no doubt that Ajuka was the best among them since while they stayed on the spot, he continued with the breakthrough, creating a better field creation technology and many others.
In the end, even if Serafall had a paper about this field creation technology, it wasn't used and just lay in the library without being used.
Yet, Riser didn't feel that it was wrong since the strength of his family's wife had always been on medical care, so instead of focusing on the unfamiliar stage, it was better to focus on what their advantage was.
Though Sona, Serafall, Rias, and the others were speechless when Riser could create it by himself without the help of anyone.
"Amazing, Riser-chan~! Help me to make one too at my house, okay~?" Serafall hugged him and asked childishly.
"Onee-sama... can you not hug my husband carelessly like that?" Sona was speechless since Serafall had a hobby of hugging her husband. Her husband might not be tempted by her older sister currently, but if Serafall kept tempting him, what would he do?
Sona knew that Riser wasn't a herbivore, but then again, if something really happened between her husband and sister-in-law... what would she do?
Nevertheless, being in the middle of Sona and Serafall, Riser enjoyed it much.
"Hahaha..." However, Sairaorg laughed and felt happy. "This stage is amazing!" While everyone was looking around curiously at the massive arena, he jumped directly into the hexagon stage in the middle like a child. He then closed his eyes and could feel the thousands of fights that happened in this place.
The scent of sweat, blood, brutal fights, screams of the fighters and audience...
Sairaorg could feel all of that in this place.
As he opened his eyes, he looked at the grey-colored ground. He thought it was some kind of sand or other type of ground, but when he looked closely, he was dumbfounded. He took a handful of the ground and asked at Riser, who was far away. "Are all of them made from the teeth and nails of the fighters here?"
"That's right." Riser nodded. "I envisioned this place to be a place where expert fighters, master martial artists, and the strongest fight each other in the human world."
"Yes, I can see that..." Sairaorg was amazed by this place and wished to have it in his own home.
"Riser, what's the name of this place?" Rias asked curiously, but her expression was complicated.
"Underground Arena," or you can call it, "Holy Land of Fighting."
Riser then told the setting of the place where it was built under the surface of the Tokyo Dome.
It was also built in 1985, 6 floors underground; volume: 320.000 cubic meters; seats: 1500. The people gathering in the arena are selected through special routes to maintain absolute secrecy. However, it is unknown whether spectators need to buy tickets or have a special pass to go in.
Hearing such a background setting, Serafall's expression was already flushed in excitement. "...is there such a place in Tokyo?" If so, then she would come to visit!
"No, this is just a background setting that I have created."
"...that's a shame." Serafall sighed helplessly.
"Onee-sama..." Sona sighed at Serafall's antics.
"......"
Nevertheless, Rias couldn't help but look at Riser with a bitter expression.
If he was like this, then why should she reject him?
Why did she come to Japan? Wasn't it due to her otaku hobby?
If her husband also had such a hobby, then wouldn't it be good?
Yet, once again, everything was too late.
Riser had become Sona's husband, but she wouldn't give up since she could tell he was still attracted to her boobs. However, she also knew that it was impossible to do anything in this place, so the only way for her to take him down was when they were in the human world.
So, how?
Riser didn't know what Rias was thinking, but he wouldn't make Sairaorg wait too long, and he was ready to jump into the hexagon stage.
But—
"Wait, Riser-chan~!"
"What's wrong, Aneki?"
"Geez, call me Onee-chan, okay~? It isn't cute to be called an "Aneki"!" Serafall pouted and still couldn't forget the feeling of being called "Onee-chan" by Riser.
That feeling excited her so much!
Riser rolled his eyes and didn't bother, ready to ignore her, but she caught her.
"Wait~! Wait~! Don't ignore me~! I am going to tell you something important~!"
"What's wrong?"
"I have made an appointment for you to meet Nurarihyon, the leader of the East Youkai Faction, in Tokyo~!"
Serafall showed a proud expression when she did all of this. Before he told his wish to make his pawns, Ni and Li, two Nekomatas, become stronger.
If possible, he wanted Serafall to introduce him to someone who could teach them how a youkai became stronger.
Serafall, then, without hesitation, did her best to help him and gave him an appointment to meet with Nurarihyon, the leader of the East Youkai Faction.
Hearing this, Riser stopped and looked at Serafall in a complicated mood. He could see that she had helped him sincerely, and she wished him the best, so for him, who had been thinking of mooching his wife's family, he felt conflicted and heavy by her sincerity.
Even though he knew it wasn't hard for her to make such an appointment, he would be lying if he wasn't moved.
So—
He was a bit embarrassed, but he thanked Serafall sincerely.
"Thank you, Onee-chan..."
"...."
Serafall blinked her eyes, then kissed him.
"—?!"
Riser was startled and quickly turned his head, so Serafall only kissed his cheek, but—
"Onee-sama!"
Sona was in a rage!
"Wait~! Wait~! You can't blame Onee-chan, Sona-chan~! Riser-chan is just too cute~!"
Cute?
Me?
Riser rubbed his face and felt weird.
"Ah, but Onee-chan is a bit busy, so Onee-chan can't come to Tokyo, so..."
"Let me guide him!" Rias quickly said.
"..." Everyone.
"No, Sona-chan can do it, right?" Serafall refused without hesitation and then looked at her little sister. "Can you do that, Sona-chan~?"
"Yes." Sona agreed since there was no way for her to let Rias guide Riser to Tokyo to meet Nurarihyon. Even though Rias was a virgin, she knew how dangerous this woman was.
If she let her guard down, the next day, she might see Riser on the bed with Rias, having done what they shouldn't do.
Such a scene definitely wasn't something that she wanted to see!
Still, Rias frowned since it was her first time to be rejected openly by Serafall like this, but she didn't care since as long as Riser came to the human world, Serafall and Sona wouldn't know anything.
By then, as long as she used her boobs, everything was okay.
Nevertheless, Akeno was also excited since, like Rias thought, as long as Riser came to Japan, anything could happen.
Still, Misla looked at this scene thoughtfully.
However, as the fight between women started in a quiet manner, Riser wouldn't make Sairaorg wait too long. He also jumped into the arena as he faced Sairaorg.
"Sorry to make you wait."
"No problem, but does this place really not exist in Tokyo?"
"......"
Looking at Sairaorg's hopeful expression, Riser shook his head. "Sorry, no."
"I see... that's such a shame." Sairaorg felt disappointed, but then his eyes were full of excitement again. "Nevertheless, we can make it here in the Underworld."
"That's right. If you want, we can make it an arena where the strongest fight with their everything secretly."
"I can't wait for that!"
"Haha..." Riser also laughed. "But before that."
"Yeah, there is something that we have to do."
The two of them took off their shirts at the same time as their fighting spirit clashed with each other before they exchanged fists.
"Ha!"
Sairaorg dashed forward as he raised his fist.
His fist was enveloped by a thick aura that was enough to destroy anything.
Yet, facing this fist, Riser was calm and moved even faster.
"It's useless."
*BOOOOOOOMMMM!*
