Chaika - The Coffin Princess v01 (2015)

Five years of inconceivable peace after two hundred years of war left erstwhile saboteur Toru Acura without a job or a meaning in life–until he saves a mysterious wizard with a coffin on her back. But when the coffin-wielding, silver-haired Chaika Trabant hires Toru and his sister, Akari, to accompany her on a death-defying journey, Toru's life of mind-numbing, meaningless peace is about to end!
