I Was a Mouse Too Long and Became the Greenhouse Detective Boss

Kanna fit in one paw what other people carried in both hands, and that made her good at finding what others missed. She had a human mind, mouse-sized limits, and a guilty heart that still hurt over one promise she broke before she woke up here. When a girl dies in the greenhouse and leaves behind a daruma with both eyes painted in, Kanna starts watching the only rival who can match her step for step. Mio is proud, careful, and impossible to read for long. Kanna wants the truth, but every clue also pulls her closer to the girl she should hate and cannot stop protecting.
