Pegitan is a penguin-like fairy adorned in soft blue and white hues, with turquoise eyes, a pastel yellow beak and feet, and a pale cream tuft of hair crowning his forehead. His attire includes a pale aqua collar centered by a blue droplet gem. His speech carries a unique cadence, marked by the suffix "~pē."

Though initially shy and uncertain, Pegitan emerges as the group’s voice of reason, balancing his quiet demeanor with insightful guidance. Passionate about hot springs, he channels his reserved energy into meticulous cleaning efforts to impress Chiyu, revealing a subtly competitive streak. As his loyalty to loved ones grows, so does his sense of responsibility, shaping him into a steadfast ally.

His bond with Chiyu Sawaizumi forms when he admires her resolve to defend her family’s hot spring inn from a Megabyogen. Together, they navigate challenges like reigniting her high-jump ambitions and balancing athletic goals with familial duties. Initially wary of her brother Touji, Pegitan gradually acknowledges his dedication, mirroring his own journey toward maturity.

Pegitan’s resilience is tested after Shindoine captures him at an aquarium, yet his compassion shines when he poses as a plushie to console Riri, a bullied girl, overcoming personal fears to offer solace. A recurring aversion to large dogs adds nuance to his timid yet courageous spirit.

Allied with Rabirin and Nyatoran, he shares a protective dynamic with Latte, the Healing Garden’s young princess. Despite his reserved nature, he confronts Byogen threats with strategic bravery. Post-conflict, he resumes life in the Healing Garden but remains a steadfast presence for his human companions.

Once plagued by self-doubt during his search for a partner, Pegitan evolves into a confident strategist, advising peers with hard-earned wisdom. His birthday, April 25th, aligns with World Penguin Day—a playful nod to his avian-inspired design.
