Gochinko is a sword trainer and master of a unique combat style known as 'stupid' or 'queer' swordsmanship. This technique specializes in distracting opponents by inducing laughter, achieved through placing flowers on his body and adopting intentionally strange stances during battle. The method exploits the enemy's lowered guard due to amusement to inflict significant damage.

He operates from a rundown small hall where he instructs students in this unconventional swordsmanship. During training sessions, he evaluated Nike's swordsmanship capabilities and judged him to be very bad at it. Gochinko holds an affiliation with the Purato people, functioning as an agent who serves JuJu, a Priestess of the Purato. His role within this group includes providing combat support aligned with their objectives.
