蘇我 屠自古 (そがのとじこ)
The "Departed Spirit of the Children of the Gods".
She is a very practical woman who can use coarse language. She also appears to be a foil to Futo's air-headed, jovial nature. In spite of the language she uses, she's actually kind, though short-tempered. Her friendship/rivalry with Mononobe no Futo led her to be unable to reincarnate like Futo and Toyosatomimi no Miko. Soga instead came back as a ghost, with two ghost tails in the place of legs. Exactly where her body transitions from human-like to ghost-like is unclear, due to the long dress that she wears. Since Soga gets her name from the consort of the character on whom Toyosatomimi no Miko was based, the two are often depicted by fans as a couple.
