An April 3 broadcast start date has been announced for That Time I Got Reincarnated as a Slime Season 4. It will premiere on Nippon TV’s FRIDAY ANIME NIGHT block at 11 PM JST.
The new season of the TV anime adaptation will run for five cours, with the first two airing consecutively. The show is inspired by Taiki Kawakami‘s Kodansha-published manga adaptation of Fuse’s isekai fantasy light novels. Kodansha USA describes the synopsis as such:
As players of Monster Hunter and Dungeons & Dragons know, the slime is not exactly the king of the fantasy monsters. So when a 37-year-old Tokyo salaryman dies and wakes up in a world of dragons and magic, he’s a little disappointed to find he’s become a blind, boneless slime monster.
Mikami’s middle age hasn’t gone as he planned: He never found a girlfriend, he got stuck in a dead-end job, and he was abruptly stabbed to death in the street at 37. So when he wakes up in a new world straight out of a fantasy RPG, he’s disappointed but not exactly surprised to find that he’s not a knight or a wizard but a blind slime demon. But there are chances for even a slime to become a hero…
That Time I Got Reincarnated as a Slime‘s first anime season premiered in 2018. There is also a spin-off titled The Slime Diaries and an OVA based on the short story that inspired 2022’s That Time I Got Reincarnated as a Slime the Movie: Scarlet Bond. February 27, 2026 will see the premiere of That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea (Gekijoban Tenseishitara Slime Datta Ken: Sokai no Namida-hen).
The manga, which is serialized in Monthly Shonen Sirius, began in 2015 and will release its 31st volume in Japan on February 9, 2026.
