Katawa Shoujo is a bishoujo-style visual novel set at the fictional Yamaku High School for disabled students in modern Japan. After a congenital heart condition abruptly changes his life, Hisao Nakai transfers to Yamaku following a long hospitalisation, where he gradually forms new friendships and may pursue one of five main romantic paths. The Alpha Repair Project restores and reconstructs an earlier, unfinished version of Katawa Shoujo that differs substantially from the official release. Several routes contain alternate storylines, scenes, character developments, and endings that were later rewritten or removed, with Hanako, Lilly, and Shizune showing some of the biggest differences. The project repairs broken scripts, reconnects unfinished branches, restores missing content, and makes the leaked Alpha version playable while preserving its distinct early-development story.

Some of the stories in the Alpha version can be much darker and grimmer than their final version couterparts. Be wary that many of the "bad" endings can touch upon subjects like selfarm, violence and suicide. More info on the changelog and Dev notes.
