Taito's classmate who is in love with him. She is shown to have a split person, which is not human. It was shown than Haruka was created out of her real person to watch out for Taito. Her 'real' personality is not as modest and shy as Haruka is, and she can be compared to Himea in terms of hostility. She is seen working with Serge and Hasga, but it is unknown as of now.
