Seigen Amawaka

Seigen Amawaka (天若 清弦) is the father of Mayura Otomi and the ex-husband of Yukari Otomi. He was also Rokuro Enmadou and Yuuto Ijika's teacher/mentor. One of the Twelve Heavenly Commanders, he bears the title of Byakko the White Tiger.

Appearance
He is always seen wearing a suit. He has long multi colored hair and rather dead blue eyes along with small bags under them. Notably, Seigen appears rather short for his age, a fact he seems to easily become furious over, as he admonished Ryougo for becoming taller than him by forcing him to sit in seiza.

After fighting with Yuuto, he lost his right arm.

Personality
He is shown to dislike lack of manners. He is quite ruthless in his own ways of training his disciples and he lacks of paternal feelings. He also never shows his own feelings, but he is very honest no matter with who he talks and what situation he is in. He is fearless in front of his opponents but careful and isn't one to back down at any cost.

Seigen is ultimately someone with a cold exterior, and he seldom lets emotion show on his face. He maintains this cold demeanor towards not only acquaintances like his father-in-law but also towards his disciples, Rokuro and Ryougo, and even towards his daughter Mayura.

Despite his many quirks, Seigen is highly respected by exorcists and his allies. Although he asks Mayura to stop calling him her father, since he is never around, Mayura notes that they understand his decision to leave, for the safety of Mayura and her mother. Furthermore, he expresses concern for Rokuro often, though he does not readily display it. In reality, beneath his tough nature lies a very kind heart. He is known to have been disapproving of children getting involved in fighting impurities, and many view him as an exemplary exorcist. Notable examples include Ikaruga Shimon, who appears to idolize him, and Arima, who bowed to him to thank him for his long service as a Heavenly Commander.

History
Seigen was born and raised on Tsuchimikado Island, he was part of a group called, "Ritsu" and it was made up of Seigen's family, the Amawaka House. Their job was to kill those who caused disturbances to their island. Most of the targets they had to kill were exorcists that caught the curse of "Jugon Monoimi". This curse had spread in Tsuchimikado Island at the time. Those who were affected by the Jugon Monoimi would fall under the influence of the Yin Aura, they will lose self-control and attack people. His group excelled in the arts of killing people rather than impurities. Seigen was forced to transfer to the Tsuchimikado Island Reserve Exorcist Training Center where Arima Tsuchimikado also went to at the time. Seigen was given another mission where he had to execute Otomi Satoshi, the brother of his ex-wife. This is the mission where he met his ex-wife, Yukari Otomi.
