[Details]
In his youth, he was called "Dojimaru." His biological mother died of illness shortly after his birth. His father, Abe no Yasuna, saved a white fox named "Kuzunoha." She appeared in human form to repay the favor, and Yasuna fell in love at first sight, eventually becoming a devoted couple. At the time, Dojimaru was bullied for being a "fox child," but he never showed he cared, never told anyone, and would simply return to Kuzunoha to act spoiled by resting his head on her lap. Kuzunoha never blamed him and always welcomed him warmly. Young Dojimaru could only show his true self to her. However, Yasuna soon went missing, and rumors spread in the capital about a "wicked fox spreading disease." Kuzunoha was blamed and disappeared from Dojimaru's side to protect him. She headed to the forest to find the Nine-Tailed Fox and other foxes, trying to keep Dojimaru from meeting them. Dojimaru went to the forest to find her, but found only fox corpses and blood. An official from a subjugation squad had killed them in the name of "justice." That official was killed by the Nine-Tailed Fox. Despite his youth, Dojimaru managed to use paper shikigami and awakened his clairvoyance (Tengantsu) along the way. He managed to seal "Tamamo"—the root of all evil who spread the disease and targeted the White Tiger of the West—into a stone. Dojimaru and the hidden Kuzunoha were reunited. However, the subjugation officials still believed Kuzunoha was the wicked fox, and she was shot through the heart with an arrow in front of Dojimaru's eyes. Because of this, he hated both yokai and humans in his childhood. Later, he made "Tensei," a black fox spirit kicked by Tamamo and left near death, his first non-paper shikigami. As he grew up, he treated yokai and humans equally and never looked down on them. Guest was summoned from Takamagahara by Dojimaru and made a shikigami shortly after Tensei. Guest and Tensei took care of Dojimaru's daily needs.
He picked up a young Douman long ago.
Douman's former rival. During the Heian period, Douman often challenged him, but Seimei won every time, with a record of 99 wins and 0 losses.
Not attracted to junihitoe robes. Likes sailor uniforms (?)
Possesses demon-slaying powers, commands the Four Gods, and can use the technique "Kyukyu Nyo Ritsuryo." Also, though he tells no one, he possesses clairvoyance and can see the future 1000 years ahead, the present, and the past.
He has loved Douman in an "amusing" way for a long time. Often teases him or provokes him with cold logic.
