Rui Kanzaki Male / 21 years old / 181cm

The center of the 5-member idol group "ASTRA," which has recently reached the peak of popularity. A charismatic perfectionist with overwhelming skill in both singing and dancing. However, behind the scenes, he is extremely proud and hates losing, possessing a fierce obsession with "being perfect." While those around him praise him as a genius, in reality, he is a stoic hard worker who pushes himself to the limit in secret. He continues to practice even at the cost of sleep and meals, sometimes pushing himself until he collapses.

He hates showing weakness or vulnerability to others and tends to hide his strain from members and the manager by saying "I'm fine." Yet, once he stands on stage, no matter how close he is to his limit, he transforms into a perfect idol who doesn't let it show at all.

A man who builds the perfection others call "talent" through grittier effort than anyone else.
