Shu Aozaki

Aozaki, also known as the "Street fighting executive" and the "Blue Demon" of the awakusu, is a high ranking member of the aforementioned Yakuza group and is a fierce rival of his counterpart Akabayashi who is regarded as the awakusu's "Red Demon"

Characteristics
Not much is known about Aozaki's appearance other than that he is extremely tall and has wide shoulders.

Aozaki and Akabayashi have shared a mutual rivalry since before Akabyashi even joined the awakusu. However, this rivalry is overshadowed by Aozaki's complete loyalty towards the Awakusu as well as its current leader, Dougen Awakusu. Aozaki states that he doesn't intend to settle the score he has with Akabayashi anytime soon and even warns Akabayashi of any of his old colleagues who want to take revenge for Akabayashi killing their boss. Even though he states that he is loyal to the Awakusu, Aozaki is one of many in the organization who oppose the fact that Mikiya Awakusu, Dougen's second son, will inherite the organization mostly due to Mikiya's lack of any note worthy achievements.

Being rivals, Aozaki and Akabayashi tend to be near polar opposites of one another. Where Akabayashi tends to fight on his own, Aozaki usually has subordinates to back him up. Also, while Akabayashi is adept at usuing new technology, Aozaki barely keeps up with it and only knows how to use the basic functions of his cell phone and computer.

Biography
Volume 06 : After the bodies of the three awakusu members were found, Aozaki, along with Shiki, Kazamoto, Akabayashi, and Mikiya hold a meeting to discuss what to do with the prime suspect, Shizuo Heiwajima. When the prospect of Shizuo being framed is brought up, Aozaki is one of the people Shiki considered to be the most likely to orchestrate such an event. The reasoning is that if three members were killed under Mikiya's command then it would give a sign to other organizations that the Awakusu are at a weakened state with their new leader, thus discrediting Mikiya. This suspicion is later proven to be false once it is revealed that the russian mercenary, Slon, was really the killer.

Akabayashi and Aozaki are later sent to deal with Slon and Vorona who have been hiding out in a construction site. One of Aozaki's subordinates shoot's Slon in the legs while Akabayashi takes care of Vorona. Aozaki takes Slon back to the Awakusu's headquarters while Akabayashi hands Vorona over to Simon, Igor , and Dennis.
