Madoka Wakamatsu

As a fierce competitor to Full Moon within the music industry, this talented singer shares a complex bond with twelve-year-old Mitsuki. Seeking to undermine her rival, she strategically debuted with "Eternal Snow," a track she intentionally intercepted to prevent Full Moon from performing it. This calculated move ultimately led to both artists releasing their own versions of the song, with her unique rendition known as the Diamond Dust Remix.
