Figure 17: Tsubasa & Hikaru EP1 - Do You Like Yourself?

Three months after moving with her father from Tokyo to Hokkaido, Tsubasa Shiina struggles to adjust to life in the countryside. One night, she witnesses a spaceship crash in the forest near her home and races towards it, discovering the ship's unconscious pilot and an alien monster intent on killing him. During the turmoil, Tsubasa enters the ship and comes into contact with a liquid-like material that transforms her into a female, teenage humanoid warrior that defeats the monster. After the battle, the substance separates from Tsubasa and becomes a clone of her that calls herself Hikaru.
