User blog comment:Wolf night10/The Final Getsuga Tenshou/@comment-1591878-20100621025751

I know that some Zanpakutou have similar abilities. That's not at all what the convo was about. All I was trying to say was that Ichigo did not start using the GT on his own. For sh*ts and giggles lets say Urahara only taught Ichigo how to channel his spirit energy through his sword. The GT is Ichigo channeling his spirit energy through his sword. Urahara may not have taught Ichigo the Getsuga Tenshou proper, but it is safe to say (if you take the time to read those chapters) that Ichigo may not be using the GT if Urahara did not teach him the preparation. Any way im sure we will find out next week. I look forward to friday.
