October 1941, as the second World War threatens to destroy the civilized world, an unforeseen complication suddenly occurs. An alien invasion! Despite the sudden appearance of these extraterrestrial aggressors, the Axis and Allies continue their destructive conflict. Only the Kishin Corps and their giant Geo-Armor Robots (a.k.a.: Kishin), developed from a captured alien robot soldier, stand between the Earth and total annihilation! A teenager, named Taishi, suddenly finds himself at the center of a struggle over a mysterious black attaché case entrusted to him by his father, Professor Tokamura. The case contains the controlling mechanism for one of the giant Geo-Armor Robots, and the Japanese Kanto Army, the alien invaders, and the Kishin Corps all want to recover the device! Between the spies, the armies, the aliens, and the Giant Robots, Taishi is in for an epic adventure—if he can survive it!

Set a few months after the original series, Wataru is called into action once again!

A healer gets booted from his party because the leader notices he isn't really contributing much to the team. Soon enough, the healer must look for new members to party with. After finding a cute martial artist to work together with, he reveals his secret: while he's a fairly mediocre healer, he actually fights well in close combat. This is the story of a support who's secretly a DPS, and where the entire conflict stems from the fact that he never told his old party he was a DPS. (Source: MU)
