Description
Yōhei Yamada discovers a lost kitten in a park, bringing her home and naming her Chi after a housebreaking incident. He lives with parents Kento and Miwa Yamada in an apartment initially banning pets. While his exact age is unspecified, visual cues show him appearing around six in earlier adaptations and closer to ten in *Chi's Sweet Adventure*, reflecting maturation across installments.
Cheerful, kind, and obedient, Yōhei adores toy trains and forms a strong attachment to Chi, engaging in daily play and routines. His journey toward independent toilet use parallels Chi’s litter training, marking shared developmental milestones.
He shares a close bond with mother Miwa, listening to her attentively, while father Kento provides steady support during challenges. Yōhei initially fears the larger cat Blackie, comparing him to a bear, though their dynamic gradually evolves.
When the Yamadas plan a move, Yōhei vehemently resists separation from Chi, declaring he always wants to stay with her and underscoring their deep connection.
In transmedia expansions, Yōhei features in *Chi's Sweet Adventure* promotional content. A series of 24 tweets titled "Mame-Chi-Shiki" (a pun blending "trivia" and Chi’s name) frame his reactions to new episodes, mixing promotion with educational cat facts and occasionally showing him researching unfamiliar topics.
His design shifts across adaptations: hair transitions from red-orange in early manga to golden-brown in later material and brown in anime iterations, visually aligning with his portrayed aging. Contextual references in ancillary descriptions note kindergarten attendance and school-related friends.
