Hitsugi no Chaika (Sub)

Toru Acura is a 20-year-old retired soldier meandering through life post-war. He encounters Chaika Trabant, a 14-year-old sorceress carrying a coffin, and follows her in hopes of finding some semblance of meaning in his life again. The two are accompanied by Toru's adopted sister Akari, the sole employed member of the group and thereby their source of sustenance.
