Abe no Yasuaki

A cool,intense guy and one of the Eight Guardians as Genbu of Earth (地の玄武?), Yasuaki is a gifted apprentice to the famous sorcerer Abe no Seimei. Despite his expressionless exterior, Yasuaki is childlike in the sense that he doesn't quite understand emotions; He even shed tears with a blank face when Akane was upset with him on one occasion.
