Kazuna Masunaga is an idol under Daikoku Production and a member of the unit MooNs. He is voiced by Yuto Uemura.
A hardworking perfectionist. Warm, gentle, and even a cooperative honors student. He’s often the mediator within his group.
HistoryHe claims the reason he became an idol was because he and a friend were told to audition for B-PROJECT, but only Kazuna was accepted. Wanting to try his best since he was accepted, he entered Bambi and began training to become an idol. He would later reveal that he worked hard to become a top idol so his mother would be able to find him. During his time in Bambi, he met Tomohisa and the two would begin their awkward friendship by working as reporters on the variety show "Genius Brunch". 2 years after joining Bambi, he met the other members that would later form MooNs.
