The four-year-old center of the film, Kun begins as a train-loving only child who feels displaced when baby Mirai arrives.
Personality
Loud, imaginative, jealous, affectionate, and still learning how to name big feelings. His tantrums are not villainy; they are the story showing a child before empathy has fully caught up with emotion.

Kun has no combat powers. His “ability” is imagination: the garden and the house’s strange family crossings let him see versions of relatives that turn everyday frustration into perspective.
Story relevance
Every major memory jump is anchored to Kun learning how his family existed before him and will continue after him.
