Harutachi Miyu

Goal: To increase her breast size.

She works at a cafe near the gym and is the older childhood friend of Shinichi (and the reason he has a hard time dealing with women). She has a very brusque way of speaking that often causes Shinichi to flinch.

She is set up by her parents for a marriage meeting, but she doesn't like it and decides to search out for someone herself. For this reason she starts to frequent the gym to improve her figure.
