Let's start from the beginning. I was your typical adult man with dead-fish eyes who only had like 4 or 5 hours to sleep. Life was tough and my boss made sure of it. I was reprimanded for misplacing one, ONE paper out of like three stacks and got a salary penalty. I was so damn tired that I didn't notice the truck coming right at me.

*BAM*

That's how I ended up in the white void where idiots like me won the isekai ticket. Now then, have I told you that I'm a huge Kamen Rider fan? Or more specifically, the anti-hero kind? Yeah sure, edgelords and all but hey, they get cool gadgets and I'm satisfied with that fact alone. I was saving up money for that sweet CSM Kaixa Gear, about 90% if it hadn't been for the stupid mistake above.

Why was I saying this? Cuz the moment I got out of the white space, opened my eyes and greeted my new…Japanese? classmate, I found the whole set inside my school bag. And it felt…real, not your high quality plastic.

That happened later though. The first moment when I realized my face was Masato Kusaka's, I freaked out so much I kinda…jumped from the windows? I know that's ridiculously dumb, but I couldn't control my body. Like the previous owner tried to reclaim his body. When we (presumably with the guy) fell into the ground, we survived with a minor back pain and I no longer felt like my entire body was rebelling against me anymore. Guess the shock finally killed the boy too. Yikes.

"Hey, what's the commotion over here?!"

It was the school guard checking on the scene and he was too shocked to react, so I grabbed my school bag, which somehow fell out with me, and bolted out as fast as I could.

"As expected, he is not a human. We should have paid more attention, knowing that he comes from that lineage."

"It's my fault, Tsubaki. I overlooked his profile as his parents all but proclaimed that he is a 'failed product' of their clan."

The girl with blue semi-rimmed glasses talked to her friend, a fellow bespectacled student with shorter hair. Tsubaki opened her files and read the profile of Kohei Kusaka: Offspring between two different beastmen tribes from Japan and Europe respectively as an attempt to create the mythical Beastkin from the time of Babel Tower. Deemed a failure due to inability to assume any bestial form similar to either father or mother. Sent to live with a relative with a similar case in Kuoh Town until he got admitted to Kuoh Academy.

"Kusaka-kun, his mental conditions started to deteriorate after the sudden visit from his parents last year."

"It was quite a sight indeed." Souna Sitri adjusted her glasses. "We need to call his guardian and find him. Satan knows what he would do if he's let loose."

After making sure no one followed me, I stopped at a secluded corner of the residence area. I took a long breath to calm down and recollect what had transpired. I jumped from the third or fourth floor and yet, I was still alive and the pain earlier disappeared completely. Was I an Orphnoch? Even Kusaka in the show couldn't possibly survive if he had been in my scenario. Being an Orphnoch was cool and I didn't have the urge to find someone to kill or feast on their hearts but I got an even shorter lifespan compared to a normal healthy human.

"Let's see what's inside…"

My eyes didn't fool me. The entire set of Kaixa Gear it was, completed with the Kaixa Pointer on the back. And it fit perfectly too, as if the previous owner had been using it before.

STANDING BY

Oh it had the original deep voice too, nice, since I hated the re-recorded one Toei used in recent shows. The phone's tiny screen actually worked, not just a damn paper for show.

"Here goes. Hope I won't die like Kusaka's friends. Henshin!"

COMPLETE

Two golden lines of Photon Blood were generated from the belt and slowly ran through my body, forming the outlines of the suit and finishing the transformation. Inside the helmet, useful information was shown to me similar to how the Iron Man suit did to Tony Stark in the movies. If I remembered correctly, all the information and instructions were stored inside the Smart Brain satellite, which were both good and bad things. Good thing was that I wouldn't be running blind, bad stuff was that Smart Brain existed and the odds of rogue Orphnochs lurking everywhere were high.

"Oiya? I heard strange noises and it turned out to be my prey."

A seductive voice echoed from the dark alley behind me. Using the X-Finder, I could see clearly that whoever, or rather, whatever it was: a serpentine monster with the upper body of a nude female. Considering that this world was DxD, she should be a stray Devil who escaped from her master and now was preying on innocent humans. A perfect target for my debut as Kaixa.

"You think I'm gonna be your dinner? Tough luck."

SINGLE MODE

I removed the Kaixa Phone and inserted the command. Just as the Devil still tried to understand what was going on, I changed the phone into Blaster Mode and started firing at her. Twelve shots were more than enough to kill a low-level Devil.

And you know what, this harlot had an annoying barrier that blocked five or six shots.

"Hahaha, your toy can't hurt me!"

"Oh yeah, I will bring the bigger gun then."

I re-inserted the phone and drew the Kaixa Blaygun, taking aim. On second thought, I decided to just end this quickly, lest I attracted the attention of the DxD main cast.

READY

Oooh the lightsaber was out! Man it looked majestic in the dark. The Lamia snarled and lunged at me with her yucky claws, presumably poisoned. I just plainly cut both her arms off with one slash.

"AAAAAAH!"

"Return that life to God, Devil." Sorry Keisuke Nago, I took your catchphrase.

ENTER

EXCEED CHARGE

The belt sent a burst of energy traveling on the Photon Blood stream into my right hand holding the Blaygun, causing the blade edge to glow even brighter. Sensing death, the Lamia desperately backed away but I was faster, plunging my blade into her torso. The cross symbol shined behind her, signaling her imminent death. Her body started to lose its color and crumble into dust, much to the Devil's horror.

"What, what is this?! What have you done to me?!"

"Complete destruction, no trace left except a pile of ashes."

I answered her simply and the Lamia let out her last scream until she was gone, the winds sweeping away her ashes.
