Hakua is Nanami's and Souta's younger sister as well as the fourteenth princess of Bladefield. Due to her being the youngest, she got all the loving and tender care from the king. Unlike Nanami, she hasn't seen the outside world.
Both sisters are quite formal with one another calling each other the thirteenth or the fourteenth because of how often they see each other. She and Nanami both have different mothers who are both Japanese and she thought that it was pretty normal for siblings to have different mothers.
- She has a habit of repeating the last thing she says whenever she talks.
