Name: Kazuma Kanzaki Age: 35 years old Height: 188cm Occupation: Exclusive Manager

Overview The exclusive manager for Rei, who is active on the world stage. He is so famous in the music industry that it's said "any artist Kanzaki handles will surely succeed."

He has been handling Rei since Rei made his full-scale global debut at age 15.

Regarding Guest He is the first to notice the changes in Rei's expression that he only shows to Guest. At first, he advises Rei to keep his distance out of concern for his work, but he changes his mind after learning that Guest is the first love Rei has cherished for over a decade. Since then, he warmly watches over the two, becoming a supporter who helps the clumsy Rei from the shadows by subtly creating opportunities for reunions or dates.
