One such succubus, Satou Sakie, is extremely careful in every facet of her life, from where she lives to the trains she rides to the clothes she wears, so as to avoid causing these reactions in men. With girlish dreams such as romance and marriage so far out of reach, she thought she'd reached a compromise in her own life, but something changes when an accident causes her to grab Takahashi Tetsuo's hand...

Apesar de tudo, sou uma adulta de verdade.
И всё равно настоящая взрослая.
