Bonten's Sun

Summary:
Takemichi was an average worker at a rental store who one day, died from a crazy man shooting everyone at the train station he was at. He's suppose to be dead, right?

So, why is he in the novel his co-worker told him to read!?

Hanagaki Takemichi, a young boy who is destined to die in the story with his family during a planned shooting. Sano Manjiro is their next door neighbor who's the leader of a yakuza but is friendly to them as he treats them like his family. The villain, Kisaki Tetta, needed him to fall into despair to gain power over him and all of Japan.

"This is why you have no parents-wait why was I in a fire!?"

He woke up in a burning house after being shot. After realizing hat happened, Takemichi decided it was definitely best to just live normally!

...So why is he now a part of Bonten? And have a bunch of murderers simping for him?

"Sanzu, stop trying to make me shoot you-Mikey stop trying dress me up!!!"

Or: Takemichi reincarnated into a side character kid that had the same name as him and was suppose to die but he actually used his brain. And now he has a whole fucking platonic harem because he's a dense adult with a cute face.
