Bleach, Volume 10

With the help of Kūkaku Shiba, a one-armed explosives expert and old friend of Yoruichi, Ichigo and his friends move a step closer to breaking into Soul Society and rescuing Rukia before she is executed. Kūkaku's plan only works if Ichigo can control his enormous spiritual power, and nobody knows how much damage that will do. Soul Society is not idle either, and sends a group of captains to meet the intruders.
