Aoi Sangū/Relationships

Mitsuba Sangu
Aoi's less successful younger sister and one of Guren's subordinates under Shinoa. She and Mitsuba are not on good terms as Aoi gives her the cold shoulder. One example of this is in chapter 39. When she arrives at Nagoya Airport with Kureto, Aoi notices her younger sister but turns her head from her and does not say a word.

Yūichirō Hyakuya
A black demon-wielder under Guren's command. He attempts to strike at Kureto from behind. Aoi blocks the attack but says he is strong.

Guren Ichinose
Leader of the Moon Demon Company. Aoi went to high school with him.

Kureto Hīragi
Aoi is Kureto's assistant and is totally loyal to him. She follows his orders without question and agrees when Shinya calls her Kureto's pet.
