Bleach, Volume 10

With the help of Kukaku - a one-armed explosives expert and old friend of the mysterious talking cat Yoruichi - Ichigo and crew are one step closer to infiltrating the Soul Society and rescuing their friend Rukia before she is executed. For Kukaku's plan to work, Ichigo must control his enormous resevoir of spiritual energy - and there's no telling how much collateral damage this will cause.
