Koromaru was already adorable in Persona 3. The little persona summoning dog looks like a puppy in Persona Q: Shadow of the Labyrinth. Cerberus appears to have darkness spells just like Koromaru’s persona had in Persona 3.
Kanji Tatsumi from Persona 4 is playable in the game too and it looks like he’s bonding with Ken from Persona 3 over knitting.
Persona Q: Shadow of the Labyrinth comes out on June 5 in Japan and slated for release in fall 2014 on Nintendo 3DS.
