Coded Soul: Uketsugareshi Idea

An army has been studying Monolith Gate, the entryway to the planet of ‘Idea.’ Gale, a young kid, controls that door and grants Jay, a soldier, exceptional powers to cross to the other side to save his girlfriend, May. The unique ability allows you to control monsters by sucking their souls. After defeating a foe, you can turn them into an ally for future battles. You can bring up to two bogeys on your journeys inside Idea, with over 100 beasts to choose from.
