4 days later
Abandoned building
From the top floor of the building, the Bugsters' base, Sora was looking at the sky.
"Kamen Riders, huh… I'm curious about what they look like… yosh, I'll just go say hi…"
With that, Sora left and headed towards Kuoh.
Meanwhile
Kuoh, Coffee shop
At one of the seats, Koneko, a member of Occult Research Club and Rias' Rook, was eating a parfait and waiting for Hiiro.
"Young Miss, your companion has arrived."
"Sorry to keep you waiting."
"Thank you for coming, Hiiro-sensei…" Koneko said as he came.
"Your orders, sir?"
"Tea and cake, please."
"I understand."
A few minutes later, after taking a bite of the cake, drinking the tea, and taking a break, Hiiro began to speak.
"So, why you called me, what do you want?"
Hiiro knew exactly what she wanted, but he dared to ask Koneko.
"Sensei… are you Brave's true identity?" Koneko asked.
"Brave…?"
'So she really talking about Brave… now what do we do now…' Hiiro thought about what he would say to Koneko.
However, at that moment…
"Helloo…!"
"! W-what the…"
"Who are you…?"
Sora suddenly appeared next to Hiiro and Koneko, startling them.
"I am Sora Takigawa. Nice to meet you both."
"Takigawa…? What do you want?"
"I'm here to say hello… and to have fun together…"
And with that, Sora took out his Bugvisor.
"That's…"
"Is that… Genm's…"
"Cultivate."
Infection! Let's Game! Bad Game! Dead Game! What's your name!? The Bugster!
"Bugster…"
While the other guests were running away screaming at the sight of Gremlin, Hiiro just stared at him and muttered.
"Correct, let's go then…!"
Sora started swinging the Rapture at Hiiro.
"Ugh! This guy…"
"Wow… you're good."
Hiiro managed to avoid Gremlin's attack, but he was thinking of something else.
'This is bad, I can't transform here… I need to find somewhere to hide first…' Hiiro thought.
Then…
"Huh!?"
"What are you doing, Toujou-san!?"
"Hiiro-sensei! Please run…" Koneko said and charged at Gremlin. However…
"Don't get in my way!"
"Ahh! No way… even with devil's power, I'm…"
Gremlin parried her attack and kicked her in the stomach, and as soon as she was doubled over, she yanked her hair, slammed her face on a table and put the Rapture to her neck.
"I'm in a good mood now… so devil, don't interrupt me."
Gremlin then tried to swing the Rapture down on Koneko's neck.
"STOP!"
Hiiro launched a flying kick that knocked Gremlin away.
"Hiiro-sensei…"
"…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… Hiiro-sensei is…"
"Ooh! So you finally transformed…"
"When human life is at stake… I have no choice!"
The two of them said as they witnessed Hiiro transformed into Brave, and at that moment Brave slashed at Gremlin with the Drago Knight Blade.
"Not bad~ that's what I've been waiting for!"
However, Gremlin avoided Brave's attacks with ease.
"Why you! What do you think you're doing!?"
Gremlin seemed to be toying with him, so Brave shouted.
"What? Of course I'm playing with you now."
"You… you've got to be kidding me!"
Gashat! Kimewaza! DRAGO KNIGHT CRITICAL STRIKE!
"HAAAAAA! HYAAAA!"
Brave unleashed a Drago Knight Blade slash at Gremlin. However, a powerful red and black energy hit Brave along with a red magic circle above Hiiro's head, and Brave was blasted by the attack.
"AAAAAAAAAAGH!"
"Hiiro-sensei!"
"That's the Power of Destruction… but it's twice as powerful as buchou's… what in the world…"
Koneko was shocked that someone used her master's Power of Destruction, and that this attack was two, no, probably three times as powerful as Rias' own.
"Kukukukuku… you'd better leave it at that, Sora…"
"Oh! Redyue-san!" Sora said as he saw Redyue standing on top of the building across him.
"That attack… are you…"
"Hm? Oh, yes, I did…"
"Why… you, who are clearly not a devil… can cast the Power of Destruction…?"
"Hahahaha… I see it now… you are a devil… I'm sorry, but I can use all the spells you devils, and not just the devil faction, but fallen angels, angels, and other supernatural beings… your magic quite easy to learn… quite interesting toys, if you ask me..."
"No way…"
Koneko was shocked even further.
"What do you want, can't you see I'm having fun here?" Gremlin asked in irritation.
"Forgive me about that… but Genm found out that you were gone, and he wanted me to bring you back…"
"Jeez, alright… I guess I'll just leave, then."
At the same time, Redyue jumped from the building and stood next to Sora.
"Sorry, Brave, but we shall take our leave."
"You think you can get away!?"
Brave pointed his Drago Knight Blade at Redyue.
"I'm quite sure you are a doctor… and you can't leave a wounded person unattended, can you?"
Redyue pointed her poleaxe at Koneko, and that moment, Redyue fired the holy light used by the angels and fallen angels at Koneko's leg and pierced it.
"KYAAAAAAA!"
"You bastard!"
"See you next time."
"Let's play again next time!"
"WAIT! Tch, they got away…"
As the two ran away, Hiiro undone his transformation and rushed to Koneko's side.
"Are you okay!? I'll treat your wounds."
He then took out some bandages and antiseptic from his bag and lightly treated Koneko's wound.
"Hiiro-sensei… so you really…"
"…As you can see… but let me ask you something, how did you know I am Brave?"
"Brave and Hiiro-sensei have the same kind of presence…"
"You can tell from that…?"
Hiiro was honestly surprised that Koneko knew that Brave was him by that alone. Then Koneko said to him.
"Can I ask you a question, too?"
"What?"
"What is your reason to fight, sensei?"
"The reason I'm fighting… as a doctor, I'm fighting to protect a person's life and to crush those who trample on it, there is no other reason."
"I see…"
"Well, fine, I'm paying, so you can go home… and I know it's futile, but if you can, don't ever tell anyone who I am."
He then took 10.000 yen out of his wallet to pay for the food they both have eaten and for the damages, and was about to leave it on the table.
"Um, Hiiro-sensei…"
"What?"
"Err… can I ask your help…? You can separate Evil Pieces, right, Hiiro-sensei?"
"Yeah, what about it?"
"My sister… please help my sister…"
"Sister?"
Next day
Seito University Hospital
When he arrived at the hospital as usual, he remembered what had just happened yesterday.
"Her sister is a stray devil…"
What Koneko asked Hiiro was that her sister, Kuroka, who was now missing, was a stray devil and that when Kuroka was found, she asked him to remove the Evil Pieces inside her and reunite them together.
"Fine, it's my job to cure stray devils, so no problem… but first…"
Hiiro took the elevator and stood in front of the director's office on the top floor of the hospital and knocked.
"Come in."
"Father…"
"Ooh, Hiiro, what is it?" Haima said to Hiiro while drinking tea as he entered the office.
"Father, forgive me, one of the devils found out that I'm Brave…"
"Ooh, okay." Haima said and drank his tea.
But the next moment… Cue spit-take from Haima.
"PFFFFFFFFFFT! HUH!? What did you say!? EEH!? EEEEEEEEEEEEEEHHH!? N-n-n-n-n-n-no way, Brave's true identity is—"
"Yeah… sorry…"
"Hey, hey, hey, hey, hey, hey! Oh no! If this continues, I'll be fired! No, the entire humanity will—!"
"Calm down! We need to take action, call the Ministry of Health."
"Ah, right… I'll call the Minister of Health, Kyotaro Hinata at once!"
Haima hurriedly picked up the phone.
Meanwhile
Kuoh Academy
"Those Kamen Riders… I wonder who are they…"
Rias was sitting in her seat, thinking about the Kamen Riders.
Then…
"Buchou!"
"Oh, Eito, what's wrong?"
"You should be pleased! I've found out the identity of one of the Kamen Riders!"
"What did you say!? And who is he?"
"Yes! One of the surgeons from Seito University Hospital, Hiiro Kagami! That's his true identity!"
