Bleach Episode 362:
Ichigo really has gotten stronger.
There are two reasons why the Head Captain agreed to restore Ichigo's power and had the other Captains and their Lieutenants put their Spirit Energy into the special sword alongside the others. The first reason is, is that they owe for the stopping Aizen, so they have to repay that debt. The second is because Ginjo, who was the first Substitute Soul Reaper, is involved in this after disappearing for a time and Ichigo needs his powers back to stop him.
Kenpachi really cut Giriko in half mid sentence, haha.
