Tomari's mother and father
Tomari Kurusu (来栖 とまりKurusu Tomari?) is a student at Kashima high school and is a classmate of Hazumu's in their second year.
Tomari is Hazumu's childhood friend, so the two know a lot about each other and have many memories from the past. Hazumu would often get bullied as a child, and Tomari would have to come to his rescue, saying that she would protect him forever.
After Hazumu's initial transformation, Tomari does not know what to do. Ayuki observes that Tomari liked Hazumu more as a boy, due to the fact that she has had affections for Hazumu for some time. At first, she is very annoyed that everyone around Hazumu is trying to make her more feminine, but ultimately realizes that while Hazumu has changed physically, her personality is still the same, and therefore still the same person inside. Tomari tries to protect Hazumu from the emotional stress Yasuna caused her by rejecting Hazumu by trying to tell Yasuna to back off for the time being, but after Hazumu says she still wants to be Yasuna's friend, Tomari does not push any further. Tomari is very athletic and competitive, so in high school she joined the track and field club. In contrast to Hazumu and Yasuna who are not athletes and rather feminine, Tomari is a tomboy who does not often partake in traditionally feminine things such as clothing, shopping, or cosmetics. In her entire life, Tomari never wore a yukata during the annual summer festival, and has to borrow on old one from her mother when she finally does wear one during the summer festival shortly after Hazumu's transformation. At least two of Tomari's female friends on the track team consider her very masculine, and like her cool character; one of these friends even says that if Tomari were a boy that she would have a huge crush on her. Unlike Yasuna, Tomari has a lot of difficulty when it comes to her affection towards Hazumu.
- Tomari resembles Maka Albarn from Atsushi Ohkubo's Soul Eater
- Both in manga and anime, she is shorter than female Hazumu.
