This is the third game in feng's Seiiki series, this time with two heroines instead of just one. Youhei's older sister Yaeka Nase is his homeroom teacher. She looks dignified as a teacher, and is very popular amongst the students. However, she's always drunk at home and leads a very loose private life.

His classmate Maika Ootori is a transfer student who is into all things Akiba. She always invites him after school to go walk around Akiba. He's gotten used to seeing her with a grilled squid in one hand and buying up doujinshi and doujin games.

This daily life, which he thought would continue forever, changed completely when rumours spread that Maika would be suddenly called back to her home country. Youhei and Yaeka try their best to help her remain in Japan.
