Kuuka belongs to the guild "Weiß Flügel Landsol Branch." Her full name, Tomi Kuuka, means "Far-view sky flower," with "Kuuka" combining the characters for "sky" and "flower."

Her personality manifests through dialogue expressing strong masochistic desires. She frequently pleads for pain, beatings, and control from an unnamed "Mister Sadist," begging phrases like "Hurt me and beat me, please!" and requests to be trained or dominated.

A specific variant, "Kuka (Oedo)," appeared in the limited-time story event "The Shogun's Travel Diary" or "Shogun Chronicles: The Whitewing Samurai." In gameplay, this Oedo variant serves as a magic tank, specializing in mitigating magic damage. She was featured on an event banner alongside other characters.

Trivia notes draw parallels between Kuuka and "Lalatina Dustiness" (Darkness) from the "Konosuba" series, citing their shared traits: vivid imaginative victimization scenarios, tank-class roles within their groups, and extreme masochistic tendencies.
