Aozaki, Shuu

青崎柊

An executive of the Awakusu-kai, known by the nickname "Awakusu's Blue Demon" (the "Ao" in his surname translates to "blue"). He is characterized as tall, standing over 190cm, with broad shoulders.
Aozaki harbors a dislike for Akabayashi and is irritated by their collective designation as the "Blue Demon and Red Demon." Their rivalry predates Akabayashi's induction into the Awakusu-kai. Nevertheless, Aozaki confesses to Dougen that he currently has no desire to challenge his longstanding rival, Akabayashi, to a conclusive battle. He even warns Akabayashi in advance when Akabayashi's former colleagues attempt to avenge their boss, under the mistaken belief that Akabayashi was responsible for his death. In contrast to Akabayashi, who prefers to fight alone, Aozaki consistently brings subordinates with him.
He does not view Awakusu Mikiya as a suitable successor to Awakusu Dougen and is quite outspoken about this opinion when Dougen is absent. However, he holds Dougen in high regard and remains completely loyal to him.
Unlike Akabayashi, he makes no attempt to keep pace with modern technology and asserts that he would smash his mobile phone without hesitation if Dougen ordered him to do so.
