Hass (はっす Hassu) is one of Rikka Takarada's closest friends.
After being told of Rikka and Yuta Hibiki together at the Seven-21 shop, she and Namiko frequently tease Rikka about it. However, the day after Ghoulghilas's attack and Gridman's appearance, she seems to have forgotten everything about them and when questioned about some missing classmates, she did not know who they were either. This routine repeated after each kaiju attack.
