This year's December issue of Hakusensha's LaLa magazine announced additional cast members of the television anime adaptation of Hari Tokeino's Gakuen Babysitters manga on Tuesday. The issue also revealed a key visual, and revealed that Ruka Kawada (Is the order a rabbit?, Kiss Him, Not Me) is composing the show's music.

The additional cast includes:

Daisuke Ono as Keigo Saikawa

Tomoko Miyadera as Yōko Morinomiya

Ayaka Saito as Takuma Mamizuka

Yuko Sanpei as Taka Kamitani

The anime will premiere in January 2018 on Tokyo MX, BS11, and Animax. A drama CD featuring the cast of the anime will ship with the 16th compiled volume of the manga on January 5.

Shūsei Morishita is directing the anime at animation studio Brains Base. Yuuko Kakihara ( Chihayafuru 2, Orange ) is handling series composition, Satoshi Motoyama ( Aho-Girl, Skip Beat! ) is serving as sound director, and Mina Ōsawa (sub-character designer/chief animation director on Kiss Him, Not Me) is designing the characters.

The manga centers on the brothers Ryūichi and Kotarō Kashima. Ryūichi is in high school and Kotarō is still a toddler. After their parents are killed in a plane crash, the two brothers find themselves living with the chairwoman of the Morinomiya Academy, who herself lost her son and daughter-in-law in the same accident. The chairwoman, however, has one stipulation for the brothers in order to live with her: Ryūichi has to work at the academy's daycare center as a babysitter.
