That Time I Got Reincarnated as a Slime Cast

The slimy isekai protagonist and two of his cute friends are as follows:

Rimuru Tempest — Miho Okasaki (Teruko from Demon Slayer: Kimetsu no Yaiba). Rimuru is the new slime form of a Japanese man. Reincarnated in a new world, evolution gave this slimy being a humanoid form.
Hinata Sakaguchi — Manami Numakura (Brandish μ from Fairy Tail). Hinata is a ruthless girl, also from Japan. She arrived in this new world with the same temperament, which became a boon for the Western Holy Church.
Shion — M・A・O (Fumika Sagisawa in The Idolmaster Cinderella Girls). Shion is Rimuru’s First Secretary. Despite the mundane title, her skills lie more in combat than anything secretarial.

Studio Eight Bit maintains a home page, a movie home page, an Instagram page, a TikTok page, and a Twitter (X) page to promote That Time I Got Reincarnated as a Slime. You can find more information about the series and the key visuals at those sites.

That Time I Got Reincarnated as a Slime and Became a Demon Lord

Satoru Mikami was an ordinary Japanese salaryman with no great ambitions. He lived an honest, hardworking, and kind life. Satoru is content with his life, despite his nonexistent love life. His colleague and friend, Tamura, and Tamura’s fiancée, Miho Sawatari, met him to seek advice. Their meeting was cut short when an assailant with a kitchen knife attacked Tamura. Satoru took the hit and died shortly afterward. Divinity then reincarnates him in another world as a sentient slime with limitless potential.

Satoru is reborn as the slime named Rimuru Tempest. Rimuru shares some similarities with his former self, but he considers them separate entities. This slime undergoes multiple evolutions and growths, eventually gaining a humanoid form and the power and title of a Demon Lord. He founded the Jura-Tempest Federation in the Jura Forest as part of his plan to foster unity between humans and monsters. However, the former Hero, Granbell Rosso, and his granddaughter, Mariabell Rosso, are part of an effort to end the peace.
