In order to cheer Haruto up after his anime was such a flop, Itsuki gets him as well as Nayuta, Miyako and Chihiro together so they can play a TRPG. Itsuki usually plays girls in games, but for some reason, Chihiro makes out their character to be Itsuki’s character’s little sister, which leads to Nayuta and Miyako also making their characters sisters of the other two. Haruto becomes the GM and does whatever he wants.
I regret not being able to have sex
 with Itsuki-senpai even once,
Ich finde es schade, dass ich nicht ein einziges
Mal dazu kam, mit Itsuki-senpai zu poppen.
Me apena no haber podido
tener sexo con Itsuki-senpai.
Me apena no haber podido
tener sexo con Itsuki-senpai.
Je regrette juste de pas
avoir pu coucher avec Itsuki,
Mi spiace però di non essere riuscita
a fare porcellate col senpai Itsuki.
Foi uma pena eu não poder ter
feito sexo com o Itsuki-senpai,
Обидно, что с Ицуки ни разу
сексом не занялась…
