Tsunemi Chiba, commonly referred to as "Chiba", is the main vocalist for BECK. Chiba's vocals are more punk and rap oriented than Koyuki's and thus more fitting for the majority of BECK's songs. Chiba's inclusion in the band is early in the series after a baseball game in which a fight breaks out between both teams. Ryusuke later hears about how he's actually a pretty good vocalist with great stage presence and later uses him to convince Taira to join BECK.
