Kana-chan is a classmate and friend of Nishihara Rumi. She serves primarily as Rumi's companion within the narrative. Unlike Rumi and Sakaguchi Ryo, Kana-chan remains untouched by knowledge of or engagement with boys' love (BL) or yaoi genres.

She has brown hair and distinctive petrol-colored eyes. Her name is written in hiragana as かな (Kana). While the hiragana script carries no inherent meaning, alternative kanji renderings suggest interpretations like 香菜 ("fragrant vegetables/greens"), 香奈 ("fragrant apple tree"), 佳奈 ("beautiful apple tree"), 加奈 ("increasing apple tree"), 夏菜 ("summer vegetables/greens"), or 花奈 ("flower apple tree"). Her birthday is recorded as May 5.

Kana-chan's interactions occur exclusively within Rumi's social sphere at school. The narrative confines her role to being Rumi's non-fujoshi friend and does not depict her involvement in BL-related activities.
