Kakōton serves in Sousou's military within a fantasy Three Kingdoms setting inhabited by cat-like Jūza. As one of multiple male characters forming romantic bonds with the protagonist Kan'u, he operates within the narrative's reverse harem framework. His relationship with Kan'u unfolds across dedicated routes in two main installments.

The first game integrates his storyline into larger conflicts such as the Battle of Guandu, though specific developments remain undetailed. Initially perceived as less prominent, Kakōton's role garnered increased player appreciation through his route. The sequel advances his romantic arc with Kan'u, introducing heightened fantasy elements. While some character routes faced criticism for narrative shortcomings or reducing Kan'u's agency, Kakōton's route received comparatively more favorable reception than others like Chouryuu or Choun.

Characterized by loyalty to Sousou's faction, his interactions with Kan'u adhere to the series' otome structure, positioning him as one of her potential romantic partners. Player discussions note his appeal, though no physical description, backstory, or detailed narrative arc is documented.
