Tōko Ichinose

Toko Ichinose, nicknamed Touko, was Seigi's classmate and childhood friend who clearly loves him. She's rather well-developed for her age. After being possessed by Iltutmish, she accidentally gets a Tatto in her forehead which, like all Tattoos, increases her physical abilities when activated. Her Tattoo is first thought to be triggered by activation of Iltutmish's tattoo, but it was discovered that its trigger was willpower. She is later killed and devoured by a monstrous Iltutmish causing Seigi to fall into despair.
