Bleach Volume 2

With Rukia's help, despite not seeing his opponent, Chad holds Shrieker at bay before Ichigo eventually arrives and defeats the Shrieker. But as Shrieker was originally a murderer in life, he is dragged through the Gates of Hell instead of dissolving into the Soul Society. The spirit that inhabited the cockatiel is released to move on to the Soul Society. In order for Ichigo to transform into a Soul Reaper when Rukia is not around, she purchases some soul candy for him from the Urahara Shop where she got her Gigai body form. But the candy Ichigo uses is actually an experimental artificial soul called a modsoul that runs off while ruining Ichigo's social image. But when a hollow appears, Ichigo defeats the monster with the modsoul's help. The soul is then captured by Kisuke Urahara, the shopkeeper who accidentally sold the candy to Rukia. After Urahara ejects the Modsoul from Ichigo's body, calling it "defective", Rukia takes the soul candy and gives back to Ichigo.
