This appears to be a special T-shirt that came with tickets to the Geddccoli the Live event held on May 30, 2004 (Sunday).

Front: "Just Being Alive is a Huge Failure (Satoru Akahori)" Back: "Because I'm a Worthless Human Being" Satoru Akahori (Polyrin) Yuko Mizutani (Kerorin) Radio Polykero Radio Osaka OBC Type...T-shirt/Apparel
