Why did Eito found out Brave's identity?

It goes back to yesterday.

"Dammit… when will I finally get my harem…?"

He was wandering around the streets of Kuoh, grumbling to himself.

Then…

"That's Koneko-chan… and who's going out with her… Toma!?"

When Eito saw Koneko talking to what appeared to be a man in a coffee shop a little far away, he became suspicious and moved a little closer to find out who she was talking to. And when he saw the man's face, he was shocked.

"Huh!? What the heck!? That's… Hiiro Kagami!? Why is he in the High School DxD world!?"

This is because in front of Eito's eyes was Hiiro Kagami, the true identity of Kamen Rider Brave, the second rider from Kamen Rider Ex-Aid he watched in his past life.

"Could it be he's Brave…" Eito looked at Hiiro and muttered.

The next moment, however, Eito was shocked once again.

"HUH!? That's Gremlin!? Why!?"

Not only Hiiro, but also Gremlin, the final antagonist of Kamen Rider Wizard, appeared before them and attacked Hiiro and Koneko.

And then…

"…I have no choice… human life comes first!"

TADDLE QUEST! DRAGO KNIGHT HUNTER! Z!

"Skill Level 5. Henshin."

Gashat! Gachan! Level Up! Taddle meguru! Taddle meguru! Taddle Ques~t! A Gacha! Do-Do-Drago! Na-Na-Na-Knight! Dra-! Dra-! Drago Knight Hunter! Z!

"I knew it, so he's really Brave!"

Eito finally witnessed the moment when Hiiro transformed into Brave, muttered, and left the place before he was caught up in the fight. And after that, Eito looked up Hiiro's identity through the internet.

"It's him… Hiiro Kagami, a genius surgeon with divine hand, whose profession is a surgeon from national hospital in Seito University… Geh, so Brave is an elite and popular surgeon, I hate it!" He spat after finding out.

In his past life, Eito was a student and an otaku. He always read light novels and fantasized about going to other worlds and become its main character. One day, he died in a car accident, and the God gave him the privilege of being an Ex-Aid by lottery. He is overjoyed to have the power of Kamen Rider Ex-Aid, his favorite, and he started to think that he is the Original Character Lord of this world. This is why Eito hated Issei and Toma, who threatened his position, but he hated Hiiro even more, who is handsome, has a high social status, is admired by everyone, and has the power of a Kamen Rider like him.

"You're getting me, the OC Lord, all worked up… Well, it doesn't matter, we have Rias-buchou from powerful devil family here. A mere doctor from some hospital is no match for her." Eito muttered to himself.

And the next day, Eito immediately went to report to Rias about Hiiro.

"This information… is it correct?"

"Yes! There is no mistake. I've seen it with my own eyes!"

"Alright… thank you for looking into it, Eito, but for now, I'd like to make peaceful contact with them and have a meeting when I have time—"

"Why, buchou!? You're a high-ranked devil, so why are you afraid of mere mortals!?"

"But…"

"And this is the one who has unjustly trespassing Kuoh, your territory, so many times! If you bend to them, they will just look down on you!"

"…You have a point there… what do you think we should do, Eito?"

"First of all, you should call them and demand them how they got that power, and then you should demand this Hiiro Kagami to teach at this school or become a surgeon at Kuoh General Hospital and keep him under your watchful eye."

"…It would be nice to be able to do that, but… would they agree…?" Rias muttered to herself, hearing Eito's suggestion that was a little too extreme.

"He's trying to keep his identity as Kamen Rider Brave a secret, and if you threaten to expose that his hospital, Seito University Hospital, has been hiding Brave from the world, he'll surrender."

"I see… it's not a very good move, but I don't have a choice… for the sake of the devils' future, even if I have to use some cowardly methods…"

"That's right, buchou!"

Meanwhile

Seito University Hospital, CR Headquarters

In addition to the five of them, Minister of Health Kyotaro Hinata who headed the organization that oversees Seito University Hospital and, in turn, CR, participated in the conversation via video call.

"I've heard from Director Haima, Hiiro-kun."

"Please forgive me for revealing Brave to the enemy, even if it was to save lives, but I have no excuses and I'm ready to take responsibility, minister." Hiiro said.

"Minister, Hiiro's actions were necessary to save lives! If I could, I wouldn't want to quit as director either! But if it's for Hiiro's sake, I'm prepared to take the punishment instead, so please! Please! Please be lenient with Hiiro!"

Haima almost fell to his knees with all his might, looking at Minister Hinata through the TV, as if he was going to crack the screen.

"Minister, I would also like to ask you to forgive Hiiro's actions…"

Asuna also pleaded with Minister Hinata.

"No, what happened can't be helped, and if I were in Hiiro-kun's position, I would have done the same thing. So I'm not firing you because of this, but…"

"What to do now…"

"Now that the enemy knows who we are, we should do something about it."

Following Minister Hinata, Kiriya and Nico, who had been listening to the conversation behind, commented.

"Yes, we need to discuss countermeasures not only with the Ministry of Health, but also with Genm and Yggdrasill… but I guess we can't go any further…"

When Minister Hinata muttered, a message came through Hiiro's phone.

"From receptionist… it's Hiiro… what's that, really? …okay, wait a minute." He said and hung up the phone.

"Who's calling, Prodigy?"

"…The devil that knows who I am, Koneko Toujou, seems to have come to the entrance because she wants to see me… I have an idea what she wants, but I'll deal with her."

That said, Hiiro was about to get out of CR.

"Wait a minute, Hiiro-kun." Minister Hinata called out.

"Something's wrong, Minister?"

"I want to ask you something."

Then Minister Hinata told Hiiro something.

Seito University Hospital, Entrance

"Hello, Hiiro-sensei…"

"We met just yesterday. What do you want?"

"I need to talk to you about something…"

"…Then let's talk on the rooftop."

Rooftop

"I'm sorry!"

As soon as they reached the rooftop, Koneko immediately apologized.

"Hiiro-sensei, your true identity… has been exposed to everyone in the club…"

"It's not like you told them… what happened?" Hiiro stared at the teary-eyed Koneko.

"Actually… there's an ORC member named Eito Kawashima… it seems that he witnessed you and I being attacked by that green monster and you transforming… and…"

"I see… then there's no need to apologize. Besides, it's my fault for transforming in public. For your apology, no thank you."

"Hiiro-sensei…" Koneko muttered.

"…And, that's all?"

"Ah, here's the thing, buchou… she wants to talk to you, and she sent me to tell you to come to the school right now, sensei…"

"Good grief… but I have a job to do. Tell her it's too rude to ask to see me right now without an appointment…"

Hiiro was about to left the rooftop when he continued.

"Ah, fine… tell her I'm available in a week if she insists, and that she can wait until then if she needs me."
