Simon Gatō spearheads the Military Junior Pre-Academy project, a clandestine initiative engineering genetically augmented soldiers—Evolved Children—to counter the extraterrestrial Wulgaru menace. He orchestrates the development of the Juria System, a neural interface embedded within AHSMB combat units that amplifies pilots’ combat prowess by syncing with their survival instincts and genetic enhancements.

His imposing stature features black hair and a perpetually obscured gaze behind grey visor glasses, reinforcing his enigmatic authority. As the genetic progenitor of Izuru Hitachi and Toshikazu Asagi, he occupies a morally contentious nexus within the MJP project, which erases recruits’ memories to forge them into obedient soldiers.

The program’s reliance on genetic modification and primal instincts stems from his conviction that the Evolved Children’s latent potential, forged through adversity and teamwork, will outmatch the Wulgaru. This philosophy drives his controversial choice to assign the fractured Team Rabbits as test pilots, betting on their untapped resilience.

A strategic pact with Teoria, a Wulgaru royal defector, supplied hybrid technology vital to the AHSMBs’ creation, blending alien innovation with human survival strategy. This alliance weaves ethical dilemmas into the project’s framework, particularly regarding the exploitation of Evolved Children and their hybridized biology.

Later revelations of his paternal ties to Izuru and Asagi expose concealed personal stakes beneath his clinical facade, intertwining his calculated ambitions with unresolved familial duty. Yet his interactions remain governed by detached authority, prioritizing the project’s success over emotional entanglement.
