|Born||July 22th, 1983|
|Hair Color||Dark Pink|
Haruka has short, purple-brown hair, which she styles in a somewhat masculine way. She, like the rest of her class, wears the default female school uniform.
Haruka was one of the students of class 3-3, though she didn't take part in many of the class's discussions about the curse, suggesting she may have been one of the students who didn't believe in it in the first place. She was friends with Naomi, whom she often ate lunch with.
Haruka was in class when her teacher committed suicide ("Sphere Joint"), and was one of the students who fled the class following that event. She was later seen sitting on the floor, in shock.
In "Body Paint", she appeared in Kouichi's nightmare along with the rest of the class, suggesting Kouichi was concerned for her safety, though this was probably more in a general sense as the two never actually spoke.
Probably as a result of her traumatic experience in class, Haruka didn't go on the class trip, meaning she is almost certainly still alive.
- Haruka is ranked A+ in Another characters ranking. She is the highest ranked minor character in the series.
