Summon Night EX-These: Yoake no Tsubasa

While you get to decide who is the dominant personality for storyline purposes, you can transform freely between both during gameplay as each has unique abilities and individual experience levels that must be used to finish the game. The game uses the same isometric 2D graphics as the strategy-RPG games, but now everything moves in real-time and you have direct control of your attacks and magic powers. Summoning creatures is possible but is mostly used as a puzzle element to take advantage of the specific abilities of each creature.
