Dai-kun presents himself as a romantic, self-styled herbivore boy consumed by an intense fascination with the titular zombie girl. His devotion crosses into obsessive fixation, marked by relentless monitoring of her actions and presence with unnerving vigilance. This preoccupation frequently triggers lapses into vivid delusions where reality blurs into elaborate fantasies of their imagined bond, merging earnest longing with unsettling compulsion.

His behavior mirrors yandere tendencies, driven by a volatile mix of infatuation that fuels intrusive, single-minded focus on the object of his obsession. Interactions teeter between ambiguous extremes—his motivations waver between earnest affection and a darker, possessive impulse rooted in control. The narrative confines his arc to a single-episode framework, offering no elaboration on his origins, internal growth, or unresolved trajectory beyond these patterns.
