About ImoTsuyo: If It's for My Young Sister, I'll Be Stronger
ImoTsuyo is an adult kinetic novel by otaku_argento, built in Ren'Py with animated 3DCG visuals. The story follows Hana Aochi after her mother's death, when she becomes expressionless and unable to laugh or cry, yet keeps acting on what she wants. Her older brother Saigo cares for her and hopes to help her return to normal. The school setting supports romance and harem themes, and the story is told through multiple protagonists. It also has an optional dictionary system for basic Japanese terms written in romaji.
The current public build is v0.32, released on September 8, 2026. Development is ongoing, with a v0.33 update estimated for public release between 10/26 and 11/04. The game runs on Windows, Linux, and Mac, and is available in English and Spanish without censorship. The v0.32 changelog mentions two new canon additions, while future notes list customizable keymaps, extra characters, more farewell events, individual routes, romaji terms, songs, sprites, mini games, and library changes.
