The Great Movie Emperor System (Anime Crossover)

I am Aizen, and I'm panicking. I thought I was at my peak from the start, with Kyoka Suigetsu being invincible, but can someone tell me what's going on with that guy in my memories called "The First Vongola"? This doesn't seem to be a pure Bleach world!
Originally, he thought that he could survive until the plot started and hypnotize Kurosaki Ichigo together to reach the pinnacle of life, but it seems that this is not possible in this unfathomable world. So he can only go to different worlds to play different identities and act to accumulate strength and heroic spirit power so that he can become the Ai-da in people's eyes again!
