Twelve episodes, from 5 July to 20 September 2026: that is the shape of the third season. The title has been doing the work of a synopsis since the first episode, and none of those five REALLYs have been trimmed off for the new run.

Bibury Animation Studios handles the animation. Takashi Aoshima is credited with series composition and Masanori Tsuchiya with sound direction, while Shinpei Nagai storyboarded the opening episode. The genre listing reads comedy, romance and ecchi, which is a fair account of how broad the jokes are allowed to get. The English-language credits name Jennifer Alyx on ADR prep and Andrew Tipps as assistant ADR engineer.

Karane Inda, Shizuka Yoshimoto and Nano Eiai carry the middle of the show. The premise stays the size it always was, only with a season three stamped on it. The last of the twelve arrives on 20 September.
