Maki Amakasu

Another of Koizumi's friends, Maki has brown hair either short or in pigtails. She tends to be a bit more high-strong than Ryoko, leading to her to act to match the situations. Several times throughout the series she states that she thinks Saji and Koizumi are a good match and wants them to be together. In manga, Maki has an elder sister who is a policewoman and a mother. Both elder sister and mother are very well-endowed women and both of them attract lots of men.
