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.
How dare you trick me with the intention 
of doing lewd things? Unforgivable!
Für die Frechheit, mich hinters Licht
führen zu wollen, werdet ihr bezahlen!
¿Cómo se atreven a engañarme con la
intención de hacer cosas pervertidas?
¿Cómo os atrevéis a tentarme así
para hacer cochinadas?
Vous allez payer
pour avoir tenté de me duper !
Come osate provare a ingannarmi
per soddisfare le vostre luride voglie! Vergogna!
Como ousam me enganar querendo
fazer coisas depravadas! Imperdoável!
Как вы посмели обмануть меня,
извращенцы, не прощу!
