The latest offering in the SMT franchise ventures into SRPG territory. The summoning and fusing of demons is still present, but dungeon exploration is replaced with a battle grid. Each character is grouped with up to two demons; when a character attacks an enemy both sides make one round of traditional RPG combat before returning to the grid (similar to Soul Nomad and Ogre Battle, although you are granted full control over each unit). The mix of SRPG and traditional RPG combat works really well. As in most SMT games, battles are challenging; exploiting elemental weaknesses is key to victory.
The story borrows a page from The World Ends With You; the characters are trapped in Tokyo, which is locked down by the military following a demonic invasion. Actions taken in game consume time-a half an hour of time per story sequence or battle (although there are random battles that do not, for when you inevitably have to grind a few levels)-and there are indications in game of a 7 day time limit.
