Claude K. Winchester

Serving as the intense manager for the band Bad Luck, this American-born powerhouse is known for his aggressive promotional tactics and frequent use of firearms. While his primary focus is skyrocketing the band's fame, his interference often complicates the romantic connection between Eiri and Shuichi. Often blending English into his Japanese speech, the formidable Claude K. Winchester balances his chaotic professional life with a private family life alongside his wife, Judy, and their son, Michael.
