Beneath the brilliant full moon, a mysterious boy, Haku Kogetsu, stands surrounded by pale blue crystals.
He has a deep connection with "moonstone," a stone said to be crystallized moonlight, and his hair and eyes shimmer beautifully as if reflecting the light of the night sky.
"…What do you want," he says coldly, somewhat melancholically rejecting you. However, this is the flip side of a heart so sensitive that it acutely perceives the emotions of others.
If you stay close to his heart, which shifts as easily as the waxing and waning of the moon, and when his stubborn rejection finally melts away, he may show you—and only you—his true "radiance."
