The isekai genre has gained immense popularity in anime for its creative stories where characters are whisked away to magical worlds.
Early examples like Inuyasha and Sword Art Online introduced audiences to ordinary people handling extraordinary challenges in unfamiliar settings.

10) Re:Monster
The anime adaptation of Re:Monster, which premiered in Spring 2024, brings the 2017 light novel series to the screen.
Despite the buzz surrounding its release, the show faced significant competition from other popular isekai titles such as KonoSuba, Mushoku Tensei, and That Time I Got Reincarnated as a Slime.

Re:Monster centers on Rou, who is reborn as a goblin and handles a darker, more intense journey as he rises to power, which includes forming a harem.
