Seigen Amawaka

Appearance
He is always seen wearing a suit. He has 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.

Powers and Abilities
Enchanted Gear: Being an Exorcist, Seigen is able to use Enchanted Gears to help him combat Impurities when fighting in Magano. Byakuren Kohou (White Lotus, Tiger Arms): As one of the 12 Heavenly Commanders, Seigen holds the title of Byakko the White Tiger which enabled him to use the White Tiger Enchanted Gear. This Enchanted Gear takes form as a huge rocky white claw that cover his right arm. Seigen is capable to cut his opponent without even moving a single inch while he uses this Enchanted Gear. After he lost his right arm during his fight with Yuuto, he's no longer capable of using the White Tiger and later he passes the charm to his daughter, Mayura as his successor.
 * Rekku Madan: As Rokuro's mentor, Seigen can use the same technique. He places a charm on rocks, then fires them using his thumb with high speed like a bullet that capable to blast away some hills and ground. Benio described the power to be on a whole different level than Rokuro.
