Hikari Takanashi (小鳥遊 ひかり, Takanashi Hikari) is a main character in Demi-chan wa Kataritai. A vampire by nature, Hikari requires blood to sustain her biological well-being. However, unlike common depiction of Vampires, she is a very active, cheerful and full-spirited girl who is more than capable of eating garlic. She also refrains from biting others' necks, though she does have fantasies about doing so but doesn't due to her unwavering kindness.
