The Chronicles of the Contaminated Prince

Miach (nee Andrew nee Braech) was reborn into a world from a revenge-fantasy book, and had no desire to take part in it in any way. So he did the smartest thing he could think of; he left. Real winners quit, after all.

This did not go over the way he wanted it to.

Namely, he got adopted as a grandson by the King of Demons.

Whoops.
