Sachi

A dog Mimikko. Hinata's older sister. Sachi is Jun's love interest early in the game. She is very soft-spoken and acts humbly, often refusing to accept praise. She calls Jun "Master" because of his behavior. She speaks highly of Jun, so much that it influenced her younger sister, Hinata, to copy her and call Jun "Master" as well.

At the end of Chapter one (relatively early in the game), she is killed by a fatal illness.
