The Bleach Wiki Lists Aizen as using
And shows Shinji pealing it back.
It lists him using it in manga
chp 107 page 17 , but that is a fight with chad.
So I am asking
- When in the manga did he use it, and does anyone have scans?
- Can this attack be negated by having more reiatsu? Is that how shinji does it?
You talking about Aizen using a Kido to hide himself and Shinji removing it?
That's in the "Turn Back the Pendelum" arc, which sometimes isn't piled with the other manga chapters for some manga sites. I could probably find the chapter page though.
