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.
So 2D means you roll two dice, 
and 3D means you roll three dice?
Bei 2W darf man also zweimal würfeln
¿2d significa dos dados, y 3d, tres?
¿2d significa dos dados, y 3d, tres?
Deux dés quand c’est écrit 2D,
et trois quand c’est 3D, c’est ça ?
Quindi "2d" significa che puoi lanciarne due
e "3d" che puoi lanciarne tre?
Então 2D quer dizer que jogamos dois
dados e 3D que jogamos três dados?
То есть, 2Д — два броска,
а 3Д уже три?
