To Wakana, people like beautiful Kitagawa Marin, a trendy girl who's always surrounded by a throng of friends, is practically an alien from another world. But when cheerful Marin--never one to be shy--spots Wakana sewing away one day after school, she barges in with the aim of roping her quiet classmate into her secret hobby: cosplay! Will Wakana's wounded heart be able to handle the invasion from this sexy alien?!
