Grimaced Souls Part 1

The Lodgers and Heroes Act are called into another UIS mission against a new race known as the Graggarockers, who are EVO-suit wearing elemental weapon-savvy lizard people who have run the isolated sectors of the Alpha Core Sector for the UIS, but one of their most troublesome targets is Remena, which is essentially the RWBY world of the AUU with 4 kingdoms that harness their planet's 'soul core' energy to fight Grimm-like Grimaces with melee-gun hybrid weapons of Zyaūar Master origin. Recently, the greatest academy in training the main defenders, the Espers and Esperesses of a worldwide organization called the Radiance, has fallen and left it's conflicted and arguing student teams trying to find the best way to defeat who caused it. With the risks of this conflict making the world vulnerable to the UIS, the heroes must find this threat and help stop it before it compromises it's safety from the Graggarockers, especially when they learn that the scourge of this world and leader of all Grimace, an Empirid-turned-Grimsister named Grimmess Occultra, who has tie-ins with all crime on Remena, is allied to the Graggarockers, offering to give them the world and it's power in exchange for their aid. With her using her power to turn the teams against each other and weaken the hope of the world around them, how will the heroes deal with Occultra?
