Manipulative-mc truyện

Mc is dies by the almighty truck-kin, he gets reborn in aot at the year 835, 10 years before canon(same age as the main trio). Mc has no advantages, Beware I may kill mc any time. No plot armor for him. (There is going to be manga spoilers, but I'll try to keep it as little as possible) [Disclaimer, I don't own any of the characters, they belong to the guy who made aot. I only own the story and my mc]
