Naruto: The Outsider's Resolve - Chapter 2.13 (044):

Kay didn't have the best life. Most of it was fairly standard, but his past was marred by a tragedy that changed his entire world. Years later he had managed to mostly rebuild his life, and had started making something of himself.

And then he woke up in a different world. A world of fantasy and [Classes], a world much more dangerous than the one he'd been born in.

The new world he's been dumped into doesn't hold anyone's hand. Even with the bonuses that being an Outworlder brings won't keep him perfectly safe. One mistake could kill him in an instant.

But maybe, with a little bit of help, he could start over once more, and start to make something of himself again. And maybe, just maybe, that something he makes himself into could be amazing. And bloody.

When various strange forces invaded, the world has since been divided into two distinct ends.

Some people worship him as a god and walk on the earth as a spokesperson.

Some people choose to drink a glass of strong wine on the scarlet night and raise the shotgun in their hands.
