Yuji Naka's company, Prope, whose most recent game is Fishing Resort for Wii, has a new iOS/Android game on the way in conjunction with the newly merged Marvelous AQL. Buddy Monster sounds like a Monster Hunter sort of thing, with just a dash of Pokemon.
Your knight is partnered with a creature, which will help you fight giant monsters in the field, but also requires your care. Taking care of your monster builds a bond between the two of you.
Marvelous intends for this to be "the greatest social RPG in history," which we can only take to mean you'll be interacting with other humans, and not just fictional critters.
