1x7 - Beck: Mongolian Chop Squad

Koyuki tries to memorize the scales at Saitou's place. Later we can see Koyuki talking with the bullies and then scolded in the teacher's office. Maho meets with him, and at Saitou's place, Koyuki tells her why he started to work for the old man. This marks the first appearance of Ryusuke's guitar, "Prudence" ("Lucille" in the Japanese original), notable for the several bullet holes it bears.
