Anata o Yurusanai

Ririko Takeuchi is a female detective who got into the career more by chance than by choice. Her father, Takeo Takeuchi, is an ex-cop who bought an old kindergarten and made it into a private investigation firm.

Anata o Yurusanai is a visual novel, which mainly consists of reading text and occasionally interacting with the development of the story. The game uses the PSP in a way it wasn't meant to be used, vertically, making the visuals resemble a comic book.
