Kagami Hekiru

Hekiru and Hikaru met Yuuto after both their fathers met over business. It was a short-lived friendship, as their father was a frequent traveler. After 10 years, they finally return. Hekiru is a girl who speaks at her own pace, and seems to be caught up in her own mysterious world. She made a promise 10 years ago, and so she returned to Japan to fulfill that promise. Hekiru tends to go for what she wants, despite her calm and cool demeanor.
