Tsurukoma serves as a maiko at Kyoto's Gion district Ichi Manor, identifiable by her distinctive glasses and traditional bun-styled hair. Her personality blends seriousness with occasional rule-bending, like secretly using a cell phone in public against maiko prohibitions, leading to a formal house warning and reflecting her inner conflict between personal desires and professional obligations.

She demonstrates meticulousness, particularly in culinary contexts, evolving from burning meals to developing specific preferences such as bread-based dishes. While fiercely loyal to house rules and traditions, she occasionally reveals vulnerabilities, lamenting how hairstyle maintenance prevents convenience store visits for days. Tsurukoma shares a contentious yet caring dynamic with fellow maiko Riko, engaging in daily arguments but showing genuine concern when Riko becomes uncharacteristically quiet, embodying an "annoying younger sibling" bond with underlying mutual affection.

Her development includes progressing through maiko ranks, marked by changing hairstyles signifying growth. This journey culminates in her graduation to geiko status, an emotionally impactful transition for the household. Her departure particularly affects Komaemi, who experiences delayed emotional reactions to Tsurukoma’s changed status and appearance, highlighting seniority transitions within the maiko community.

In Ichi Manor’s hierarchy, Tsurukoma occupies a middle position—senior to trainees like Kiyo but junior to figures like Momoko. She mentors Kiyo in kitchen operations and maiko protocols, displaying kindness beneath a stern exterior. During "Dish of the Day" segments, she discusses food trivia with Kiyo and Sumire, expressing enthusiasm for comfort foods like bread pudding that evoke personal nostalgia.
