"Prepare yourselves!"

With that, Zangetsu Shin used his Sonic Arrow to slash at Ex-Aid.

"Shit! Hey, Genm or something… hey! Where did he go!?"

Scared of Zangetsu Shin's strength, Ex-Aid tried to ask Genm to do something about it. But Genm that had been there a moment ago had disappeared.

"Where are you looking at!?" Zangetsu Shin yelled as he mercilessly struck Ex-Aid with his arrow.

"Damn it all! This is it!"

Gashat! Kimewaza! MIGHTY CRITICAL STRIKE!

"ORRAAAAAAAAA!"

Ex-Aid tried to hit Zangetsu Shin with a desperate Rider Kick. However…

"Such simple attack won't work on me!" He said and avoided the kick just before Zangetsu Shin was hit.

Lock On!

"This finishes it."

He docked the Melon Energy Lockseed to his Sonic Arrow.

Melon Energy!

"AAAAAAAAAAAAAAHHHH!"

He slashed at Ex-Aid as he passed him with the energy from the Lockseed.

"Damn! The Rider Gauge…"

"What's the matter, is that all you got!?" Zangetsu Shin shouted as he swung his Sonic Arrow at Ex-Aid.

"Now's the chance!"

Taka! Tora! Batta! Ta-to-ba! Tatoba, Ta-to-ba!

"DIEEEEEEEEEEEEE!"

Having transformed into OOO once again, Saido tried to slash at Zangetsu Shin from behind with Medajalibur in his hand.

"HAAH!"

"UAAAAAAAGGH!"

Duke blocked his attack and slashed at OOO with his Sonic Arrow.

"You're quite prone to attack from behind, it seems."

"Shut the fuck up! You bastards! I'm the OC Lord and Rias-buchou's peerage! Don't think you can get away with this!"

With that, OOO swung the Medajalibur at Duke with rage.

"OC Lord? So, you're a reincarnated devil?"

"Yeah, that's right! I'm not like those lowly humans! I am chosen to be a superior devil!"

"Hehehehehe, I see, I see… TOTALLY UNFORGIVABLE!"

"AAAAAAAAAAAHH!"

Duke then slashed at OOO with all of his might.

"Reincarnated devil… I can't stand devils, they create things like Evil Pieces that transcend human beings without using the drivers I invented, and there's some scum right in front of me who's been turned into a devil by those things… disgusting! DISGUSTING!"

Duke then stomped on the fallen OOO and hit him again and again with his arrow.

"Ah, owowowowow, help, help me!"

"What's wrong? You're above human, aren't you? Is that all you got!?"

He then kicked OOO.

"This is the extent of the devil's trivial inventions… you should know your place, devil."

Lock On!

He docked the Energy Lockseed into the Sonic Arrow and pulled the string as hard as he could.

"The world doesn't need a being that is more than human without using my drivers, so begone."

Lemon Energy!

"UAAAAAAAAHHHHHH!"

Duke then launched a Sonic Volley, a finisher that shoots high-energy arrows at OOO, blasting him away.

"Well, well, well… pathetic, two Riders crawled on the ground, I guess that means that a great power is no better than trash if it's used by a garbage." Duke mocked, provoking Ex-Aid and OOO who were lying on the ground.

"Damn! I can't let this happen!"

"You're defying the Lord…"

Ryoichi and Eito said to Zangetsu Shin and Duke after their transformation was cancelled.

"Oho, you're still got spirit?"

"Then we'll eliminate them completely this time."

Duke and Zangetsu Shin pulled their bowstrings.

"NO!" Rias fired the destruction magic in the area, sending a cloud of dust into the air, temporarily blocking their sight. And when the dust subsided, there was already no one there except for Zangetsu Shin, Duke, Brave, and Lazer.

"Dammit! We lost them…"

"So they're not that good, but very quick to escape." They said.

Then…

"I don't know who you are, but thank you for saving my life."

"Me too, thank you."

Brave and Lazer thanked them.

"Don't worry, we haven't introduced ourselves yet."

Zangetsu Shin untransformed, followed by Duke. Then, Zangetsu Shin changed into a young man wearing a suit and exuding an aura of maturity, while Duke's identity is a young man wearing a lab coat and shorts who looked like a researcher.

"I am Takatora Kureshima, CEO of the Yggdrasill Corporation."

"I am Ryoma Sengoku, head of the Yggdrasill Corporation's R&D, pleasure to meet you, Hiiro Kagami-kun, Kiriya Kujo-kun."

"Why!? Yggdrasill!? And where did you get my name!?" Brave demanded, wary at their knowledge.

"Hahahaha, we are connected to the WHO, the Japanese Ministry of Health, and we know most of CR, so we are on your side…"

"…What do you think, Examiner?"

"…He's quite suspicious, but he's honest."

"I see…"

As he spoke, Hiiro untransformed, followed by Kiriya.

"Once again, I am Hiiro Kagami, a doctor from Seito University Hospital's Department Surgery and CR."

"Kiriya Kujo, the hospital's medical examiner and CR Kamen Rider."

As they introduced themselves, Takatora stepped forward and held out his hand to Hiiro.

"I see, it's an honor to meet you, the genius surgeon of the medical world, I am Takatora."

"The honor is mine as well, to meet the president of that giant welfare company, Yggdrasill Corporation."

The two men shook hands with each other.

Meanwhile

Kuoh Academy

"We're finally here…"

Rias fled to Kuoh Academy with Ryoichi and Eito, as well as Toma and Issei, using teleportation magic. By the way, Ryoichi and Eito had fainted and were lying like corpses.

"Rias-senpai, why did you even save me, I'm…"

"You saved me when that black warrior that looks like Eito's transformed form attacked me, so I thought I should save you too…"

"Is that so… what about Issei, by the way?"

"About that, he's now my Pawn, and I'm going to do everything I can to help him."

"I see."

"I'll tell you and Issei the details later, so be careful on your way home."

"All right, I'm leaving, then…"

Toma left the place.

Meanwhile

Abandoned building

"What are you going to say, Genm?"

"Saki… what is it?"

"I've been watching the entire thing. You attacked Rias Gremory and her peerage of those scum reincarnators, and now you give Brave's Gashat to that scum reincarnator with the power of Ex-Aid… and Yggdrasill Corporation… I know, I know it's you who leaked this information to them…"

"Hehehe, you saw right through me." Genm said with a chuckle.

"Good grief, what do you think you're doing?"

"What do you mean, what? Hmph, this is all a stepping stone to us Bugsters for taking over the world…"

"Stepping stone?"

"Yes, this time I went out of my way to help the devils, and brought together CR and Yggdrasill, the two forces opposing the devils…"

"Don't tell me…now that you, a Bugster, seemed to have cooperated with the devils, the CR and the Ministry of Health will suspect a relationship between the devils and Bugsters, and by pairing them with the Yggdrasill Corporation, whose goal is to completely eliminate devils and supernatural beings from the human world, the CR will move to completely eliminate the devils as well as us Bugsters… if that happens…"

"That's right, as a result, the relationship between the devils and humanity will deteriorate, they will hate and fight each other, and then devils and supernatural beings will be eliminated by the humans, and the humans, when they are exhausted…"

"We Bugsters will take over the world…"

"Correct… devils, supernatural beings, and humanity, they're going to have to fight to the bitter end…" Genm said with a grin under his mask.

"What a pity for the devils and reincarnators, caught between two forces, humanity and Bugsters… well, I guess they deserved it… anyway, it'll be interesting to see how these devils and reincarnators end up~"

"Heh, that's right."

The devils and reincarnators, they still don't know that they are being played around in Genm's hands.
