An alien arrives on Earth with no memory of why he exists, and the only way to find answers is to fight alongside a teenager who has no reason to trust him. The bond that forms isn't built on exposition or destiny, it's forged in the space between two beings who don't belong anywhere else. Orgun moves like a show made by people who understood that real connection happens when you're both running from something, and sometimes saving the world is just what you do while trying to save yourself.
An alien warrior arrives on Earth with no memory of who he is, only an urgent need to understand his own existence. When Orgun crash-lands in the city, he encounters Tomoru, a young man caught in the wrong place at the wrong time. Rather than destroy the witness to his presence, Orgun sees something in Tomoru worth protecting. The two form an unlikely partnership, bonded by circumstance and necessity. Their alliance faces immediate testing as the Evoluders descend on Earth with genocidal intent. These beings view entire worlds as obstacles to be erased, and they've set their sights on humanity next. Orgun possesses power beyond anything Earth's military can comprehend, yet his amnesia leaves him fighting blind against enemies from his own past. As battles escalate across the city, Orgun and Tomoru must discover whether their connection holds the key to stopping the Evoluders, or if Orgun's mysterious origins condemn Earth to destruction. This is hard sci-fi action wrapped in 90s OVA sensibilities: explosive, compact, and uninterested in long exposition. The tone balances desperate stakes with genuine camaraderie between two characters learning to trust each other under fire.
