1x6 - Rainbow

The other bullies attack Sakuragi, while Ishihara listens from outside the cell. Ishihara leaves content that Sakuragi will be bludgeoned to death by morning. In the morning, Ishihara opens the cell, but is horrified to see all the bullies beaten and bloody on the floor. Cowed by the beating they suffered, none of the bullies are willing to admit it was Sakuragi's fault, causing Ishihara to leave in a rage. Unable to intimidate Sakuragi, Dr. Sasaki suggests Ishihara make Sakuragi break the rules by hurting his friends. Realizing Ishihara's goal, the boys bear the abuse to protect Sakuragi. Sakuragi, no longer able to watch, grabs Ishihara and is in turn placed in solitary confinement. Ishihara plans to starve Sakuragi to death saying that he and Sasaki can't let him out because of what he knows. One year earlier, Sakuragi had a roommate named Ei'ichi who was sexually molested by Dr. Sasaki. Unable to live with the constant abuse, Ei'ichi committed suicide. Guard Kumagai reveals Ishihara's plans to the boys in 2-6. Turtle manages to sneak food to Sakuragi's cell, restoring his will to survive.
