Kuri-Manjū blends the traits of a Japanese chestnut bun and a honey badger, sporting a tan and light brown fur pattern that embodies his hybrid nature. His mannerisms echo those of a middle-aged Japanese man, frequently seen snacking or sipping alcoholic drinks before releasing a resonant, satisfied sigh. A liquor license holder, he temporarily lost this privilege due to undocumented drinking but later reclaimed it.

Defying norms with a preference for cold baths, he contrasts sharply with peers, often displaying hangover symptoms like a flushed complexion. Though his gruff exterior might unsettle some, he reveals kindness by sharing meals or offering coffee to companions. A culinary enthusiast, he enthusiastically pairs dishes with beer, though early anime adaptations substituted alcohol with juice for censorship, later restoring accurate depictions in follow-up seasons.
