Hikaru Hoshina

Hikaru Hoshina is an imaginative, curious 13-year-old second-year student fascinated by constellations and space. Stubborn and intuitive, she thoroughly investigates whatever catches her interest and enthusiastically draws other people into activities, sometimes without noticing when her enthusiasm becomes inconsiderate. She is also caring and supportive, though capable of becoming deeply upset.

Her catchphrase, "Twincool~☆," comes from her father.
