Blue Seed Character Orochi no Orochi

    Orochi no Orochi; monster of the Kushinada legend that was slain by the Storm god Susano-oh. Orochi makes his debut at the beginning of Blue Seed and he captures Momiji to sacrifice her inside of a ceramic field in order to free the Aragami race from the power of the Kushinada. Not only is he the arch enemy of the Kushinada, he is also the one responsible for killing Mamoru Kusanagi's parents and enslaving him to the Aragami race.
    Orochi gave the toddler Kusanagi seven of his souls to make him stronger so that he might protect the Princess Kushinada. He did this not out of kindess but out of determination to keep the humans from sacrificing the young Princess and sending the Aragami back into eternal slumber. He is Kusanagi's master, and he doesn't take to betrayal very well, attempting to kill Kusanagi for rebelling against the Aragami.
     He is unsuccessful, however and ironically ends up dispensing another of his Aragami souls to save Momijiin order to ensure the Aragami's continued presence in the human world.
    He's a giant plant, so I don't think he has a blood type, and he's probably excluded from the zodiac as well.
