Mysterious Space

"Where… am I…?"

I found myself in a completely white space.

"What's going on…? I'm pretty sure I was in a tunnel collapse in America… While I was trapped, I treated the injured as best I could, and I'm sure I protected a girl from a steel frame that came down from the ceiling… I must be dead after all, given the circumstances… which means I'm in the afterlife…"

I traced my memory and concluded that this blank space was the afterlife.

Then…

"Did you notice that?"

"Who are you…?"

When I looked in the director of the voice, I saw a woman with a divine aura.

"I'm one of the world's administrators… a goddess, if you may…"

"Goddess, huh… I never expected such beings really existed… So, what does this Goddess want with me?"

"Yes, let me apologize first. Actually, you are not destined to die yet, and the collapse was not supposed to happen. I'm so sorry!"

"What, what the hell do you mean!?" I demanded hoarsely. "What do you mean, the collapse wasn't supposed to happen!? That's bullshit! How many people do you think died in that accident!?"

I was a doctor before I died, so I really valued the importance of life, and the thing I hate the most is when people die for reasons other than old age.

"I'm very sorry! Actually, it seems that another god burned your life list and that of the people who died in the accident to fuel the fireplace… and as one of those gods, how can I apologize…?"

"…I see… but as long as it wasn't your fault, I don't need an apology."

"Huh… but…"

"Let me ask you something, what happened to the injured man I gave first aid to while he was trapped in the tunnel?"

"According to the records, they were rescued after that…"

"Hmm, I see… that's good." I smiled a little and said.

"You're so kind, worrying about others before yourself…"

"If you are a god, you'd know that I was a doctor before I died, so why wouldn't I be relieved to hear that my patient didn't die… By the way, why did you call me here?"

"Oh, that's right, this is actually a complete scandal on the part of us gods. So, we've decided to reincarnate you and the others who died in that accident to another world."

"Reincarnation? You said another world. What world is that?"

"In your case, it's the world of a novel called High School DxD."

"What's that?" I asked the goddess.

I've only ever been interested in medicine, and I've never watched any anime, games or novels.

"It's a quite famous novel, you don't know?"

"No."

"Is that so… I'll tell you about it briefly…"

And a few minutes later

"Well, that's pretty much it."

"I see, it's quite a disturbing world… but that's okay." That's what I said when I heard about the world.

"Of course, I'm not going to send you unarmed into such a dangerous world, so I'm going to offer you three gifts."

"I see… then I only want one thing… to be reincarnated without erasing my memories."

"Huh? Is that all you want? Other people ask for magic, divine treasures, or some other cheat weapon…"

"I don't want any of that. I'm a doctor, and I'm going to be one in the next world, so all I need to take with me is the medical skills I've learned and developed." I said.

That's right, I'm a doctor, and I'm proud of it. I don't need magic, or any of the other things that I don't understand, just the knowledge to hold a scalpel and save a patient's life, that's all I need.

"But… other than devils and fallen angels I just explained, there are actually many other reincarnated people."

"What?"

"The god who burned your life chart… has a hobby to take people's lives just for the fun of it and reincarnate them in a random world with a reincarnation bonus chosen by lottery, and there are several reincarnators in the world of High School DxD who are sent by that god…"

"…I see… then you can choose the rest of my reincarnation bonus on your own, I don't care what other bonus you give me as long as you fulfill what I just said."

I clenched my fists, inwardly furious at the other god for toying with people's lives, thinking that if I ever met that god, I would definitely hit him.

"You can say whatever you want… hmm?"

She flipped through some documents, stared at one of them and then looked at me.

"Your name and face… were you born with them?"

"Of course…"

The face and the name were a gift from my parents, there was no way I was going to get a face lift or change my name.

"It's decided, then."

"Well, if you've decided, then get started, because I don't like wasting time."

"Okay."

With that, my feet began to glow and my body gradually disappeared.

"Then I wish you a wonderful new life, good luck, Hiiro Kagami."

As soon as the goddess said that, I, Hiiro Kagami, lost consciousness.

21 years later

A warehouse somewhere in Japan

"Damn it! I've just escaped from that asshole of a master…" A woman was holding her chest with a pained look on her face.

She is a reincarnated devil, but the master who reincarnated her was a man with many problems, and she couldn't stand him, so she took the opportunity to flee from him.

However, a short time after she fled, she began to lose control of her magic power. In fact, when she was reincarnated as a devil, she was implanted with an Evil Piece. However, the Evil Piece that was implanted in her had been tampered with in such a way that if she left her master's side, it could cause her magic to go out of control and turn her into a monster.

There was only one fate for her now: to become a runaway stray devil and have her master defeated by someone else. As her mind and body were being torn apart by desperation, she heard footsteps.

"Who is it…"

"…So it's a stray devil… and it's on the verge of going out of control due to the illegally modified Evil Piece implanted in it… from the looks of it, it's Stage 1…"

She looked towards the sound of footsteps and saw a young man in a white coat standing there.

"You're human… then you better run… because I'm about to…"

She's about to become a monster, she was going to say.

"You can still be saved, it would be against the doctor's oath to abandon a life that can be saved."

"Save…? How? …I can't…"

"You will. Trust me. There is nothing that I cannot cut."

"Hmph, yeah ri—"

When the woman got to that point, her body transformed into what could only be described as a monster, with only the lower half of her body being beastly and four strong limbs.

"Human… food!"

The stray devil that had turned into a monster lunged at Hiiro with its four arms.

"Stage 2, it's about time."

In his right hand, he held a blue game cartridge-like item, officially known as a Gashat, and pressed the activation switch.

TADDLE QUEST!

At the same time, something that looked like an RPG startup screen appeared behind Hiiro, and at the same time, treasure chests appeared everywhere in the warehouse.

"Skill Level 1, Henshin!"

Hiiro then inserted the Gashat from Taddle Quest into his belt, the Gamer Driver.

Gashat! Let's game! Metcha game! Mutcha game! What's your name!? I'm a Kamen Rider!

As soon as the voice came on, several panels appeared in front of him, and he selected one of them. His body transformed into a costumed warrior, Kamen Rider Brave Level 1.

"We will now commence the surgery to remove the stray devil. Phase 1, removal of the runaway Evil Piece from the patient's body."

Gashacon Sword!

Brave took the Gashacon Sword, a sword designed to look like it was covered in flames, and continued to use it to deliver flaming slashes while skillfully avoiding the attacks of the stray devil.

"AAAAAAAAAAARGH! FOOD! I'LL EAT YOU!"

"Heh, how weak."

Even if the attack is powerful, there is no way it can hit him without it losing control and thinking. Brave said as he dodged the attack and slashed the body of the stray devil as he passed it. Then, a large number of "HIT" letters appeared around the stray devil, and at the same time, an explosion occurred and the female devil that was supposed to have turned into a monster, or perhaps it was the former devil since it was separated from the Evil Piece. Anyway, the female devil was blown away by the blast, and Brave jumped high to catch the woman.

"Separation successful, we will now move to phase 2."

And then Brave looked at the direction of the explosion. And there was the monster, looking even more hideous than before. He'd done this kind of separation surgery many times, and he'd found out that if he separate the Evil Piece from the devil, the Stage 2 will end up with something like this.

"Technique Level 2."

Brave then pulled the lever on his belt.

Gachan! Level up! Taddle meguru! Taddle meguru! Taddle Quest~!

Brave then transformed into Kamen Rider Brave Level 2, a blue knight-like warrior. And as soon as Brave transformed into Level 2, the monster attacked Brave with four arms.

"That's a very nasty attack. Then it's freezing treatment. I'll try to block that attack first."

KO-CHIN!

With that, Brave switched the Gashacon Sword from flame mode to ice mode, and at the same time, waited with the sword in the opposite grip.

"RAAAAAAAARGH!"

Then, as soon as Brave switched the sword to the opposite grip, the monster used its four stiff hands to attack Brave. He quickly jumped back, avoided the attack and regained his footing.

"Got you."

He hit the B button on his Gashacon Sword and stabbed it into the ground, freezing the area and also the lower half of the monster, completely restraining it.

"RAAAAAAAARGH!"

"Now you can't move. Commencing cauterization."

KA-CHIN!

Brave switched back to the flame mode, and then inserted the Taddle Quest Gashat on the Gashat Slot on the Gashacon Sword.

Gashat! Kimewaza! TADDLE CRITICAL FINISH!

"HAAAAAAAAAH!"

Brave took the Gashacon Sword with its two powers of fire and ice, glided across the frozen ground, and sliced the monster in half as he passed it.

"AAAAAAAAAAAAAAAAGHHH!"

KABOOOOOOOOOOOOM!

And then the mortally wounded creature exploded without a trace.

Gashun!

"Good grief, I never thought I'd have to do an emergency surgery so soon after coming back from the States."

After saying that, Hiiro undone his transformation and called a certain place.

"Father, please contact the Ministry of Health who performed the separation surgery on the stray devil and tell them to take the subject into custody, the location is…"

He, Hiiro Kagami, is a reincarnated genius surgeon, and a person who took pride in saving lives, who was given the power of Kamen Rider Brave, one of the heroes who protected humanity from supernatural beings.

Notes

Hiiro Kagami (21)

In his previous life, he was a 24-year-old genius surgeon with qualifications in cardiac surgery, neurosurgery, digestive surgery, and respiratory surgery, and was famous for never failing. In a disaster, he was trapped in a tunnel collapse when a steel frame dropped on him and died, and was reborn in the world of High School DxD. At the age of 19, he performed his first surgery on a pulmonary artery sarcoma. He has mastered all aspects of surgery and has been called a "Human Hospital," the "Divine Hand," and a "Prodigy of the Medical Society." The privilege of reincarnation is the medical knowledge he gained in his previous life, as well as the reincarnation privilege chosen at random by the Goddess: the Gamer Driver, the transformation compatibility, and the three Gashats of Taddle Quest, DoReMiFa Beat, and Taddle Legacy.

In addition to the fact that he has the same appearance as Hiiro Kagami from his previous life, he also has the same habits and personality, so it would be more accurate to say that he is Hiiro from a world where Kamen Rider and the Bugster Virus did not exist. The only difference is that Kamen Rider Ex-Aid's Hiiro's father is the director of a university hospital, while this Hiiro's father is the director and chairman of the university hospital.
