A high school girl gets possessed by Oda Nobunaga's soul mid-rescue attempt and suddenly she's holding a gun that rewrites physics. The show never bothers explaining the rules, it just keeps throwing bigger historical spirits and weirder weapon synergy at the problem until you stop asking why and start laughing at how absurd it gets. Shio doesn't want this power, doesn't understand it, and treats each fight like an inconvenient disaster that keeps interrupting her life, which is exactly the energy that makes 13 episodes of genre chaos feel earned instead of exhausting.
Shio Ogura's school trip to Taiwan takes a brutal turn when supernatural creatures emerge from nowhere, forcing her into a firefight she never asked for. Government operatives show up wielding impossible weapons, each one channeling the power of legendary historical figures through something called E-Gene technology. They're outmatched and desperate until Shio's instinct to protect her classmate triggers something dormant inside her: the spirit of Oda Nobunaga, the ruthless warlord, suddenly awakens in her body. Now Shio finds herself conscripted into an underground war against an interdimensional threat, armed with one of history's most formidable military minds residing in her head. The catch is learning to work with a centuries-old warrior whose tactical genius doesn't always align with a teenager's moral compass. Action collides with dark comedy as Shio navigates monster-hunting missions, military bureaucracy, and the bizarre reality of sharing her consciousness with a historical legend. The show balances high-octane combat sequences with absurdist humor, never taking itself too seriously even when the stakes climb higher.
