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 guess I'll start, since I'm the oldest.
Na dann … Ich als älteste Schwester
mache den Anfang.
Entonces, empezaré yo, que soy la mayor.
Entonces, empezaré yo, que soy la mayor.
Je commence,
puisque je suis l’aînée.
Allora inizio io, dato che sono la maggiore.
Como eu sou a mais
velha, eu vou começar.
Начну, наверное, я,
раз уж старшая.
