Jyuka Mutsuoka serves as a guardian of healing and verdure within the Arbor Clan, tasked with nurturing crops and mending the wounded in alignment with his clan’s sacred duties. To walk among humans, he masquerades as a high school student, though he chafes at being dismissed as merely cute, fiercely striving to prove his seasoned capability.

His familial ties include an older brother, though the nature of their bond remains undefined. On missions, he forges bonds with those grappling with hidden anguish, such as Kei Riju, a fading idol desperate to reclaim her spotlight. In aiding Kei, Jyuka clashes with a rival star employing shadowed tactics to dominate their industry, their clashes unfolding across surreal battlegrounds shaped by artistic visions reminiscent of van Gogh’s swirling skies. While these trials showcase his resolve to mend fractured lives, these victories carry shadows, sometimes feeding the very corruption he seeks to eradicate.

Jyuka’s nature blends compassionate grace with a hunger for acknowledgment, his polished composure often cloaking vulnerabilities about appearing childish. Each interaction weaves tension between quiet uncertainty and unwavering loyalty to his role, his history hinted at but never fully unveiled. Bound by the Ten Laws of fairy conduct, he navigates missions where operational necessities war with higher principles, testing his moral compass.

Combat exposes his fragility: battlefield hazards like corrosive acids breach his defenses, rendering his protective garments useless and forcing him to seek allies’ aid—a humbling contrast to his cultivated image of self-reliance.
