The Greatful Sound concert is slowly creeping up. Ryusuke and Lucille have caught the attention of the music loving public, but they have also caught the eye of hip-hop mogul Leon Sykes. It seems Leon is after Lucille and will do anything, including murder to get her back. Ryusuke must turn up his charm to avoid a collusion with death. Meanwhile, Koyuki has had a sudden spark of inspiration. Could this be the song to send them over the top?

Yukio Tanaka
Yukio is a completely average 14-year-old boy, nicknamed "Koyuki." His life has been pretty dull... But everything changes when he meets Beck! No, not the famous singer, but a patchwork, Frankenstein-looking dog. Beck's owner, Ryusuke, changes Koyuki's life forever. Soon, Koyuki becomes a budding musician in a band called BECK!

Ryusuke Minami
Ryusuke has played in various underground rock bands. He's cool and edgy, and Koyuki is in awe of him--both as a persona and as a musician. He's responsible for Koyuki's newfound interest in music.

Izumi
Yukio has had a crush on Izumi since they were in elementary school. She's cute and sweet, and she gave him the nickname "Koyuki." She's into rock music, and because of her, Koyuki delves deeper into the world of music.

Beck
Ryusuke's loyal, stiched-together dog. He's the glue that stuck everyone together.

Tanabe
Koyuki's trouble-making school friend.

Harold Sakuishi is one of Japan's most talented creators. His knack for three-dimensional characters and incredibly detailed artwork (take a look at the musical intruments in Beck!) have made his books -- Gorillaman, Bakaichi, and Stopper Busujima -- quite popular.
