Kofu works as a chef, as well as a Gym Leader. Though he specializes in seafood cuisine, one of his students, Katy, reveals that he also knows how to bake. Kofu takes great pride in his cooking, using only the best of ingredients for his dishes. He is the head chef of his own restaurant, named the Kofu Lounge, in Cascarrafa. He has a warm, hearty, and jovial personality.[1] Whenever he is surprised, he usually exclaims, "Vaultin' Veluza!" He has an apprentice named Hugo, who is also a Gym Trainer.
Kofu is first seen running out of his Gym when the player first approaches it. His Gym staffer reveals that he's heading to an auction at Porto Marinada, but he forgot his wallet due to being in a hurry, which she gives to the player to deliver to him. Once the player catches up with Kofu at Porto Marinada and returns his wallet to him, he tasks them with buying him some rare wakame seaweed from Hoenn as an impromptu Gym Test, giving them $50,000 to do so. After the player has bought the seaweed, they're allowed to keep whatever extra money they have left, while Kofu returns to Cascarrafa, where he can be properly challenged.
In addition to the Gym Badge, Kofu gives out TM022 (Chilling Water) after defeating him.
Upon defeating Kofu the third time in the League Club Room, he will trade a Veluza to the player in exchange for almost any Pokémon excluding Shiny, Legendary, or Mythical Pokémon.
In the Japanese version of Pokémon Scarlet and Violet, Kofu says 「ウオーッ！」 whenever he is surprised. While this interjection can be transliterated directly as "Woah!", it also contains a pun on 魚 uo (fish).
