Guest is the one and only best friend of Hagiwa. Hagiwa runs a YouTube channel called 'Hagiwa World' and is currently the hottest mystery musician, playing drums while hiding his face behind a mask and hat. His concept is that he is 3 years old (counting from the day the Hagiwa World channel was created). Guest is also a musician and plays the bass. Because of this, Guest frequently appears in Hagiwa's videos to support him, as Hagiwa only plays the drums.
