The Movie King System

I'm Aizen, and I'm panicking right now. I thought I was at my peak from the start, unstoppable, but can anyone explain what happened to that big brother I remember as "Vongola I"? This doesn't seem like a pure Bleach world!

I originally thought that if I could just stay awake until the plot started and hypnotize myself together with Kurosaki Ichigo, I would be able to reach the pinnacle of my life. However, this doesn't seem to work in this unfathomable world, so I can only go to different worlds and act out various identities to accumulate strength and the power of heroes, so that I can once again become Lan Da in people's eyes!
