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 we have to deliver a letter to 
a sage living deep in the forest.

al sabio que vive en el bosque…
Entregar una carta
al sabio del bosque…

al saggio che vive nel cuore della foresta.
Então temos de entregar uma carta para
o sábio que mora nos confins da floresta.
Надо доставить письмо
мудрецу, что живёт в лесу?
