The special edition packs the game with a B3-size poster and illustration booklets, as well as a special box, a set of four acrylic key chains, four connecting tin key chains, and a mini tote bag, all themed after the set’s respective sextuplet.
Now, according to an Amazon Japan listing, it looks like the currently-named Osomatsu-san: The Game is in the works for PS Vita.
Back in January, Idea Factory and its otome game wing Otomate announced plans to make an otome game out of the Osomatsu-san anime, but the platform had yet to be revealed.
