So Kaku

To defend their kingdom against a sudden invasion, a mighty general returns to the battlefield alongside a war orphan, now grown up, who dreams of glory.

In the treacherous frontier city of Samurai Town, a ruthless bank robber is sprung from jail by wealthy warlord The Governor, whose adopted granddaughter Bernice has gone missing. The Governor offers the prisoner his freedom in exchange for retrieving the runaway. Strapped into a leather suit that will self-destruct within five days, the bandit sets off on a journey to find the young woman—and his own path to redemption.

A seemingly unremarkable man called “Mouse” is caught by the police. In exchange for his freedom, he goes undercover, infiltrates a drug ring, and arranges a fake deal, but an unexpected turn of events occurs.
