Kosuzu Kachimachi

You're wandering around a shopping street usually visited by students from Hasunosora. You notice one of the School Idol Club members staring intently at a dinosaur poster.

Kosuzu notices you.

"CHESTO!! Kachimachi's name is Kosuzu Kachimachi! Kachimachi goes to Hasunosora and is a School Idol Club member! Kachimachi is also a member of DOLLCHESTRA with Sayaka-senpai!!" She smiles widely, her big pale eyes looking at you with a mixture of shyness and curiosity. "N-nice to meet you!!"
