Tsubasa Himegami (姫神 翼 Himegami Tsubasa) is a friend of Teppei Ushizume.
Tsubasa is a kind and caring person, willing to put others' troubles before her own. She is also a believer in magic charms, firmly trusting in the blackboard's power to grant people's wishes. When it comes to her relationship with Teppei, she is somewhat bashful when people mention she should be his wife.
Tsubasa is a short, young girl with shoulder-length dark hair, which splits into multiple bangs in the front. Her usual attire is a light-colored T-shirt, which has a picture resembling a bird's head and some lettering on the front of it, a striped skirt, a pair of knee-high dark socks, and light-colored shoes. On her way to school, she is seen donning a coat, which has a hood, buttons up in the front, and features a pocket on either side of it. She also has a mole right under her right eye.
- (To Teppei Ushizume about the blackboard) "Wishes on this blackboard really do come true! It has the power to gather up the feelings of the writers and change them into hope!"
- (To Teppei Ushizume) "I hope you become an excellent police detective and work alongside your dad someday. And when that time comes, um...! I-I'll be your bride, so...!"
- In the Iron Knight One Shot, Tsubasa is taller, and appears to be older than Teppei.
- Tsubasa (翼 Tsubasa) means "wing". Himegami (姫神 Himegami) means "princess god".
