Adapted from the Nintendo 3DS game Puzzle & Dragons, this fantasy TV series is set on Dorogoza Island, a place overflowing with a resource called Drop Energy. Players channel that energy into the monsters on their side, and once those allies have grown powerful enough, they can challenge foes in puzzle wars. Victory brings rewards, but the fate that awaits the losers remains an open question, and only the courageous dare to step into these monster-filled contests.
