Instead of sending Christmas cards, it’s common for Japanese companies to send New Year’s Cards. Nippon Ichi Software may have hinted about a future game in a card send to Famitsu. Underneath The Witch and the Hundred Knight and Disgaea 4 Return are close ups of three characters. Perhaps these are from a new game?

Atlus snuck in a similar teaser on their holiday card which has a character from Devil Survivor 2: Break Record, the Nintendo 3DS version, hidden in the "A".
