Misaki Jinguji, alias Yellow Gelato, operates as a core member of the heroic Gelato 5, mentoring teammates and mediating disputes with a blend of warmth and wit. Her past as a disgruntled office worker saw her channel frustrations through covert skirmishes against the antagonistic Gekko organization, catching the eye of Daigo Todoroki, who spotted her potential during one such clash and recruited her.

Bubbly and extroverted, she naturally assumes a "big sister" role, dispensing advice on romance and teamwork—though her tips often spiral into humorous chaos when she acts on tipsy whims, like urging Fudo Aikawa into ill-fated romantic overtures mid-celebration. Her love for socializing fuels a penchant for gossip and late-night drinks, yet temporary sobriety sparks introspection about how others view her beyond her lively facade.

In combat, she combines tactical precision with improvisation, such as infiltrating an amusement park under the guise of a beloved mascot’s costume. Though cheerful, her sharp eye catches teammates’ unspoken tensions, leveraging these insights to fortify unity.

She playfully teases Daigo while juggling leadership duties with an insatiable curiosity about their off-duty lives. Her arc explores the friction between her upbeat, reliable persona and quiet vulnerabilities, particularly fears that her party-girl reputation masks her true self.

Pivotal scenes feature her negotiating truces, leaping into slapstick antics to diffuse stress, and joining allies in high-stakes battles against Gekko. Together, these threads paint her as a dynamic anchor for both her team’s missions and their shared humanity, weaving duty with humor and heart.
