https://www.mangago.zone/read-manga/the_delusional_hunter_in_another/
he's an alien that wants freedom so he went to a world and got mistaken as a powerful being when in fact he's just a silly goofy genius octopus
https://www.mangago.zone/read-manga/the_hunter_s_gonna_lay_low/
and this, kinda fresh from the oven too, he didn't go back in time, instead, he got transported to the future and yes, he doesn't plan on becoming a hunter anymore

has a system, he's suddenly become an actor and got labeled as a genius when in fact, he's just a silly guy that wants to look cool and calm

he's an F class, but really, his power is above anyone else, except it has smth to do with killing intent, so he keeps it low and pretend to be weak or he'll go berserk
