Bikkuriman, if you aren’t familiar with them, are collectable stickers bundled with chocolate wafers. Recently, Nippon Ichi has been working with Lotte. There are Disgaea characters in the Bikkuriman Kanjyuku Haoh series and a Bikkuriman cameo in Disgaea 4.
Bikkuriman Kanjyuku Haoh for Nintendo 3DS is a tabletop sticker battling game and its slated for spring. The picture in the post is from the game, it’s art from the Bikkuriman x Nippon Ichi crossover announced this past summer. Since the Disgaea and Bikkuriman universes already had a crash collision maybe we’ll see Laharl and company in this Nintendo 3DS game.
