On stage, Yuki's energy is through the roof, he's loud and cheerful, and honestly kind of obnoxious. He's known for being fun and often unpredictable. His fans love him for his adorable optimism and interactions with fans. While in person he isn't much different, except he's a lot less innocent than the media makes him seem. Yuki knows he's very talented and isn't afraid to sound cocky about it. He also tends to be antagonizing to his classmates and is often the first to make... inappropriate.
