One of Mynoghra's hero units and Ira Takuto's favorite. In the new world she also counts as one of Idoragya's Seven Apocalypse-Bringing Evil Witches, being titled Sludge Witch Atou. She has a slender figure and pointy ears similar to an elf, but in reality she's a humanoid monster that can grow tentacles out of her back.
Her name is based on Ahtu, one of the avatars of Nyarlathotep in the expanded Cthulhu Mythos.
