Stranger's Manga

Looks great
Yuma the eunuch devotedly served Empress Hela Rosé, but his life and the empire fall apart when she goes insane. Determined to discover what led to this, Yuma eats magic berries to go 40 years into the past and nurtures his skills as a swordmaster, which he couldn't do as a eunuch. Armed with memories and new abilities, he tries to prevent the horrors of the previous timeline. But will such big changes lead to his desired outcome, or will Yuma learn that the past isn't meant to be tampered with?
