MIAA-295 Ichika Matsumoto is a tsundere who grew up in the city and looks like an adult, but lives with her younger cousin only during the holidays.

I have a younger cousin. - I grew up in the city, and I'm mature and cheeky. - During the long holidays, my parents decided to go on a trip, and I decided to keep them at my house in the countryside. - It's hard to say that to me, but he does naughty things... - This is the opposite of what I like! - ? - I'm left at the mercy of this cheeky but lovable little devil! - Living together like this might not be such a bad thing...
