Ichihime serves as the priestess of the Mahjong Soul Temple, consistently sporting distinctive cat ears while firmly maintaining her human identity. She devotes herself wholeheartedly to eating and napping, often prioritizing these activities over her other duties. Her bond progression stories within the game explore themes connected to the nekomata, a type of cat yokai. These narratives include "Nekomata - Rumor" at Bond Level 1, "Nekomata - Encounter" at Bond Level 2, and "Nekomata - Confusion" at Bond Level 3. Later levels introduce stories like "Ichihime Gone Missing" and "Strange Rumors," culminating in "A Cat's Memory," unlocked at full bond. Collectively, these tales hint at potential supernatural origins and personal mysteries surrounding her. As the central character in the chibi-style anime "Mahjong Soul Pon☆," Ichihime's daily life and mahjong activities at the Mahjong Soul Shrine are depicted, featuring companions such as Kaguyahime and Wanjirou. Her role expands in "Mahjong Soul Kan!!," where she takes up live streaming alongside her shrine duties, engaging in modern activities. Her visual design showcases diverse thematic outfits, including a default kimono, "Beach Party" attire, "New Year" clothing, the "Invincible Ichihime" costume, and "Spring Song" dress. Official cosplay costumes typically feature key components like her headwear, kimono, waist cummerbund, and stockings. Ichihime's speech is marked by the frequent use of "nyaa" as a verbal tic. Examples include her introduction: "Hello! My name is Ichihime. Glad to meet you-nyaa!" and her reaction to gifts: "Nyaa? Is this for me? You are so kind!" She also expresses enthusiasm for potential food presents with lines like "A gift? Is it something yummy?"
