Mega Man Star Force Tribe

Mega Man Star Force 2 takes place after the events of the second video game. The story centers around the lost continent of Mu, where an ancient civilization vanished. Remnants of Mu exist as UMAs (unidentified lifeforms), which begin merging with humans in search of Mu's treasures, the powerful ooparts. The ooparts have the potential to revive Mu, but they also attract enemies like Subaru and War-Rock, who soon meet Professor Orihime and join her quest to find the ooparts and stop the UMAs.
