Skeleton Knight in Another World, Volume 3 (Skeleton Knight in Another World #11-15)

The quest to save the elves from slavery continues: Arc and Ariane depart for the capital city, Olav, in search of new leads. There, they meet with Chiyome, a beast-eared ninja who hopes likewise to save her own people from bondage. She approaches the Skeleton Knight with an urgent request - one he can't ignore! It's a team-up between knight and ninja to right the wrongs of a corrupt city, as Arc's path charges headlong into new dangers.
