Misaki Jinguji, alias Yellow Gelato, operates as the nurturing older sister of the hero squad Gelato 5. Her past as an overworked office worker culminated in a stress-driven clash with Gekko troops during a nighttime skirmish, catching Daigo Todoroki’s attention and securing her swift recruitment.

Bubbly yet dependable, she thrives on camaraderie, playfully inserting herself into teammates’ personal affairs—dispensing tips on romance, though her alcohol-tinted advice sometimes backfires. A sober hiatus triggers introspection as she grapples with her reputation as a lighthearted reveler, contrasting her self-perceived maturity.

In battle, her "Frostverwandlung" transformation powers the explosive "Megaton Lemon Crash" strike, heralded by her spirited catchphrase, "Zitronenduft und der Geschmack des Lebens!" Tactical ingenuity shines during covert missions, including an enemy base infiltration and a theme park operation where she dons a "Mimion" disguise to rally allies.

Initially vexed by Daigo’s rigid adherence to anti-fraternization policies, her flirtatious persistence gradually forges a balanced partnership. Post-retirement, they pivot to shared civilian life, launching a restaurant that crystallizes their romantic bond.

Her journey navigates the tension between free-spiritedness and duty, evolving from deflecting stress with humor and drink to anchoring herself in purposeful commitments—all while preserving her infectious loyalty and knack for uniting the team.
