Hikaru Tsukino

Hikaru is a student at Tokya High School, and a senior member of the Archaeology Club. A kind and generous girl, Hikaru spends most of her free time at the Starlight Orphanage watching over the kids, and plans to do it full-time after their graduation. Hikaru is an innocent and good-willed girl, but she can also be ditsy and gullible at times, as well as quite oblivious to Yasu's feelings for her.

It was at Starlight that Hikaru met Yasu when they were both seven, Yasu having lost his parents.

Hikaru is always doing her best to help others, but she is losing sleep, skipping classes and even failing some of her exams over the hours she spends at Starlight Orphanage. This all led her to fear that she might never graduate. It all may be to Yasu's advantage, as he can choose to spend more time with Hikaru and help remedy her grades, slowly flourishing a sweet - mellow romance.

She also loves idol groups.
