Summary
Tansui is an Arowana Fishman who serves as a member of the Macro Fishman Pirates. He possesses a remarkably open-minded manner of speech, a trait that frequently infuriates both Macro and even Duval. He is noted to be skilled in Fishman Karate, similar to Kuroobi and Kapoty, though his combat abilities are never actually demonstrated in the story because he is defeated before he has the opportunity to employ them.
