Kawamatsu

Kawamatsu the Kappa debuted in the One Piece Trading Card Game as part of the Wano Country-themed expansion sets. The card depicts the loyal retainer of the Kozuki clan, drawing directly from Eiichiro Oda’s Wano Country Arc, where Kawamatsu’s design reflects a blend of traditional Japanese folklore and the series' distinct character aesthetic. He is characterized by his kappa features, samurai attire, and his dedication to Hiyori Kozuki, emphasizing his role as a protector within the narrative.

The card design captures the tactical nature of the character, often emphasizing his defensive abilities and synergy with other Wano-themed cards. As with many characters in this set, the illustration aims to translate the manga's high-energy visual style into a functional TCG format. It was released to provide players with defensive utility, and it is generally received by collectors as a faithful representation of the fan-favorite guardian, maintaining the visual continuity established by the anime and manga adaptations.
