Chaika -The Coffin Princess-

Tooru Acura, a former saboteur from a 300-year war, struggles to find work in the post-war era. The war ended five years ago when the Eight Heroes defeated the Taboo Emperor, Arthur Gaz, who ruled the Gaz Empire with an iron fist for 500 years. Chaika Trabant, the late Emperor's daughter, hires Tooru and his sister Akari to help her find her father's scattered remains for a proper burial. The Council of Six Nations, formed by the nations that allied against the Gaz Empire, sends Albéric Gillette to capture Chaika.
