Wakabayashi's younger brother encounters Hige and Mioko out together, and teaches Mioko something that should help her get between his sister and Hige...
Would ya not be concerned if your sister were to lose her purity?
ألن يُقلقك إذا ما فقدت أختك طهارتها؟
Du willst doch sicher nicht, dass deine
Schwester ihre Unbeflecktheit verliert, oder?
¿Quieres que tu hermana pierda la virginidad?
Ça ne te gêne pas qu’un jour, ta sœur 
ne soit plus blanche comme neige ?
A te va bene che tua sorella
perda la sua purezza?
Para você, tudo bem se 
a sua irmã não for mais pura?
