Who Asked Aizen to Become a Marine?

Looking through the documents marked S-class top secret in his hand, Tang En quickly frowned. I saw lines of text clearly appearing on the white paper. Name: Aizen Soyousuke. Navy number: 012367 Position: Major. Comprehensive evaluation: Although this person lacks strength, he has a gentle personality and is loyal to his duties. He is a very loyal navy and can be assigned important tasks. Tang En couldn't help but hissed as he watched, his brows twisted into twine. No, who asked Aizen to become a marine? Who wrote this damn review? As time went by, Tang En gradually realized that the world was crazy after all. Characters from other worlds appeared one after another and joined his team. Uchiha Sasuke, Enichi Tsukuni, Tanjiro Kamado, Ryoten Tanjiro, etc. This world is still a mess after all.
