Thanks to his father's sudden remarriage, Tojo Basara finds himself with two beautiful new step-sisters. Their names are Naruse Mio and Maria. Mio wakes him up in the morning, while Maria stands in the kitchen wearing a suggestive outfit...
But you understand now that "Youth 
in an Unmarked Lot" was Maria's!
Aber du weißt nun, dass dieses
"jugendliche Eskapaden" von Mariya kam?
¡Pero ya sabes que "Mi juventud en 
una casa sin número" era de Maria!
¡Pero ya sabes que "Mi juventud con mi hermanastra 
en una casa sin número" era de Maria!
Ma adesso sai che "Gioventù 
in territori inesplorati" era di Maria!
Mas agora você sabe que o "Juventude
num Lugar Escondido" era da Maria-chan!
Но ты же знаешь, что спецвыпуск 
«Юности» был от Марии!
