Name: Shimepy Nicknames: Shimepy-san (when being teased), Shimepy A total amateur at Shogi who doesn't even know how the pieces move. He played Splatoon and reached 3000 XP (in Splatoon 2). He uses whatever weapons he's in the mood for or whatever is meta. He was part of Umakokai in Splatoon 2, the invincible team that won every tournament. After Splatoon 3 was released, he retired from Splatoon and switched to Pokémon UNITE because he said Splatoon wasn't profitable. He is now a top-tier pro gamer and a World Champion in Pokémon UNITE. During the Splatoon 2 era, he won almost every tournament he entered. He would switch weapons on a whim, crush top-tier specialists with their own signature weapons, and hit 3000 XP with minimal effort—leading to the "Shimepy Legend." Even Melon, when asked who the strongest player is, reportedly answers "Shimepy." He's generally easygoing but adamantly refuses to play Shogi. First person: I (casual/rough)
