Protagonist travels between different anime worlds to right wrongs and uncover his reason for being along the way.

Zhuang Feng is in his last year of high school, and he’s just moved to the city. He lives with his good-for-nothing cousin, who’s always on business trips falling for get-rich-quick scams, and his Saozi (sister-in-law), who tries to make his life miserable as much as possible. There’s one upside, though; she. is. freaking. hot. But one day, he found a piece of her underwear in the bathroom…. And unfolded a series of events that will turn his life upside down.

- Description from Novelupdates

This is not your usual isekai novel. it has my unique world background, unique power system and i am trying it make it a unique experience for every reader. :)

Athan, a 16-year-old boy, lived until he was killed for a stupid reason. (stupid reason & more in the prologue:v)

But it seems that fate had stored different things for him as after death as he transmigrated in the magical world inside a dead body of a boy with the same name and same facial features as him.

He also found out that a mysterious black whirlpool seemed to be inside him.

Was someone responsible for his transmigration? if so then who? and why? or was it pure coincidence that he got a new chance at life?
