Merry Christmas. Just for today, I'll do anything you want Onii-sama.
Ah... Okay.
Really!? Yay! Let's play Momotetsu together!!! For 100 years!!!
Momotaro Dentetsu (abbreviated as Momotetsu here) is a japanese board game kinda like Monopoly. The duration of a game can be set from 1-100 in-game years. 100 years games apparently take around 30 hours to complete.
