Next day

Kuoh Academy

While Toma was getting ready for his morning class, Issei came running into the classroom.

"Hey, Toma, do you remember?"

"Remember? Remember what?"

"I mean Yuuma-chan, my girlfriend."

"Ooh, I know. I mean, how could I forget something so shocking?"

"Really!? Thank goodness… Actually, Motohama and Matsuda said they don't remember it at all."

"Ooh, I see what you mean."

'Rias-senpai probably erased their memories.' Toma thought.

Then he heard a voice echoing from the class room.

"Are Issei Hyoudou and Toma Hiraga here?"

The school's idol, Yuuto Kiba, was there.

"Yes, I'm here, I am Toma and this is Issei."

"Actually, Rias-buchou want to meet you."

"Huh!? Rias-senpai!? That Rias-senpai!?"

Issei yelled, it's no wonder, Rias is famous as the one of the Two Oneesan of this Kuoh Academy.

"Let's go!"

"I'm with you."

"Good. Then follow me."

The three of them arrived at the old school building behind the school and entered one of the rooms.

"What is this room…" Issei thought as he entered the room. Toma, on the other hand, felt uncomfortable.

This is because the two reincarnators in this room, Ryoichi and Eito, are blatantly glaring at him and Issei with murderous look. Toma looked around, trying to avoid eye contact with the two.

"Ah…"

"Koneko-chan, you too?" Toma said to Koneko, who was sitting on the sofa eating some yokan.

"Huh, you two know each other?"

"Yes, Yuuto-senpai, we met on the roof a few days ago."

Koneko explained to Kiba. Then Issei tapped Toma on the shoulder.

"What, Issei?"

"Toma! Look at that!"

"What do you mean by that—WAAAAAH!"

When Toma looked in the direction Issei was pointing, he saw a shower where a silhouette of a person who appeared to be Rias was taking a shower.

"W-why would a shower in this room, but that's doesn't matter! What a nice body…"

Issei was so moved that he shed tears as he spoke.

"H-hey, Issei… let's take a picture." Toma said as he took out his cell phone.

"I-idiot! I get your feelings, but calm down! About that… can you share with me later…?"

"Of course."

He told Issei to share the photos with him later, rather than stop him.

"Perverts…"

"What a piece of shit. Why they are even here."

Koneko and Ryoichi commented as they saw the scene.

"You're just like him…"

"Hey, hey, it's not that bad, Koneko-chan."

"But it's the truth."

Koneko looked at Ryoichi with even more disdain than Toma and Issei as she spoke.

"Ara, ara, you must be the new members of the club."

""Y-you are!""

A dark-haired girl walked into the room, and the two yelled comically.

"I am Akeno Himejima, vice president of the Occult Research Club, and I hope you don't mind my presence."

"I-I know. Nice to meet you too!"

To tell the truth, Toma had a crush for Akeno, one of the Two Oneesan at the Kuoh Academy. That's why he was so nervous.

"What a wonderful club."

"This is heaven!"

The two of them said happily.

"Sorry to keep you waiting, you two."

"D-don't worry about it."

Rias finished her shower and came out of the shower room.

"Now that we're all here, we'll welcome you. As devils."

"Huh? What do you mean by that…?"

"Issei, Rias-senpai's full name is Rias Gremory, and she is a member of a noble devil family."

Toma explained.

"Oh, Toma, you know about us?"

"To a certain extent, yes."

"Buchou! Be careful, this guy is an agent of evil."

"You don't know what he's thinking."

Ryoichi and Eito interrupted their conversation.

"Ryoichi, Eito, stop it, you're being rude."

"Buchou, you are too lenient! He's an enemy of the world!"

"I know why he'd be here!"

They didn't listen to Rias' attempt to stop them, and pulled out the OOO Driver and Gamer Driver, ready to start fighting.

"Haah… I can't help it, Akeno."

"Alright."

""WAAAAAAAAAAAAAAAAHHHH!""

Akeno blasted a thunderbolt on the two of them, knocking them out.

"Both of you, forgive us, these two are, how do you say, a little selfish, please forgive their rudeness."

"B-buchou, you sure have a hard time with these two." Toma said, feeling sorry for Rias.

"Well then, let's get back to the topic at hand, starting with Issei."

Rias then explained that Yuuma was a fallen angel, that he had died yesterday and had been resurrected by a devil pawn, and the relationship between fallen angels, devils, and angels.

"So, what happened yesterday…"

"It's all real…"

"Is that so…"

Issei muttered. Then Toma spoke up.

"Um, Rias-buchou. You said that you would welcome me as a devil, but is everyone here a devil?"

"Yes, everyone but Eito is a devil."

"Huh? Why is that?"

"I don't know, at first I wanted to make him a devil, but when I put the Evil Piece close to his body, it was rejected."

"It's rejected?"

The reason for this is that Eito has a small amount of Bugster Virus in his body. In fact, antibodies to the Bugster Virus, as well as those infected with game disease and Bugsters, rejected the Evil Pieces, and cannot be reincarnated as devils. However, this is not known to anyone other than CR, Genm Corporation, and Yggdrasill Corporation, which was provided with some of the research materials on the Bugster Virus as a preliminary step to building an alliance.

"Well, other than that, Toma, I have two questions for you."

"What is it, buchou?"

"What is that black-clad group that was around you yesterday, and that monster you transformed into? Eito and Ryoichi said they are the enemies of the Kamen Riders, called Shocker."

"It's true that the Kamen Riders and the men in black that I summoned, the Shocker Combatmen, are enemies, but honestly, I have no intention of antagonizing them."

"Hah! Bullshit!"

"Yeah, right! You're just trying to trick us by saying that!"

The two who had fainted woke up and yelled.

"I want to tell you both to be quiet, but you have a point. I personally want to believe that you are not an enemy, but…"

"I wish I could believe that somehow, but…"

They both struggling with the answer.

"Ah, then, Toma, why don't you become a devil like Issei?"

"Devil?"

"Yes, the Evil Piece that is here now can reincarnate you as a devil by using 1 rook, 1 bishop, and 1 pawn. I'm sure that will solve any problems we might have…"

"I think so…"

He looked around, and finally glanced at Issei, who was beside him.

"I'll take your offer."

"Good, then let's get started."

Rias then picked a rook piece from the Evil Pieces and brought it close to Toma, which then entered his body.

"Okay, now you've been successfully reincarnated as a devil, please get along from here now on, Toma."

"Okay, buchou."

At Toma's words, Ryoichi and Eito grabbed Toma's shoulders.

"You better watch out, you bastard, I'll never accept you."

"Me too."

Toma knew in his heart that he was going to be in trouble. Then Toma had something on his mind and asked Rias a question.

"Speaking of which, may I ask you something?"

"Go ahead."

"The Kamen Riders that appeared yesterday… do you know who they are?"

Toma was curious about Brave, Lazer, Zangetsu Shin, and Duke, who had appeared before them yesterday and had proven to be clearly hostile.
