[Reborn!] A Deadly Commission

A story set in the world of Resident Evil, featuring 27 and William. Tsunayoshi Sawada is the original protagonist and the bottom. There is a previous book about him and 27's canon story, Black Rain, which you can read if you like, but it is not necessary to enjoy this one. This is an alternate timeline where Reborn successfully adopts William.

Blurb A:

For the seventeen years before this, Tsunayoshi Sawada had always thought he was an ordinary person: he graduated with terrible grades, failed to get into college, and couldn't find a job.

Everything changed when he finally got an offer from a technology company. He had no idea why they wanted to hire a nobody with a vocational school diploma, but at least he'd finally found a job and could stop being a shut-in! The job was in Raccoon City? Fine, he'd head over right away.

A few days later, William, who had gone from being a psychopathic killer to a mercenary only to find that nobody had hired him in ages because he didn't look intimidating enough, got a job from the Vongola. Their future Tenth Generation boss had gone missing in Raccoon City, now cut off from the world after a massive zombie outbreak.

William: Is this a death wish? No. I won't go, not even for more money.

William, a moment later: (Takes the photo) (Studies it carefully) (Kisses it and slips it into his pocket) What a cute kid. I'll take the job.

It wasn't until he actually found Tsunayoshi Sawada that William realized just how wrong he had been. This wasn't a cute kid at all. He was a sleeping lion, and William was pinned beneath him by those deadly claws, unable to move.

Could he still ask for a bigger fee? What, if they get married, he can inherit the whole fortune... Even then, no way. But you really are wonderful. (Nuzzles Tsunayoshi Sawada's cheek.)

Some friend: Are you sure you want to marry him? His real age is four...

William (covering his mouth): He's twenty-four if you round down, and he looks your age.

Some friend: How much did you round down? (Gets stabbed in the butt with a knife and runs off.)

Blurb B:

A melancholy little tune, and a melancholy two-player subway selection System.

Dear player, would you like to choose 27's perspective, responsible for the horror and suspense, or William's perspective, responsible for hacking monsters and killing zombies?

Clear every level to unlock a hidden character, and see things from the perspective of the ultimate winner. (Be careful not to let it notice you!)

Supporting characters include Ada Wong and Leon. The entire cast of Katekyo Hitman Reborn! appears in their original roles.

The protagonist is the older twin brother, currently enjoying a peaceful life after years away from being a hitman.

Theme: I really like you. Stay with me forever.
