In the anime, Angel Yan had still been far too immature when she became king. More precisely, her mindset had remained that of a "warrior."
Because Holy Keisha was the absolute leader of the entire Angel Civilization, they revered Holy Keisha beyond measure and had never considered that they themselves might become the Angel King. Naturally, they were lacking far too much in that regard.
Even Angel Yan now would need a long time to become a qualified king of a civilization, even with Holy Keisha's guidance.
Fortunately, the Angel Civilization had ample time to wait for Angel Yan to grow.
Aizen was different. He possessed every qualification needed to become a king.
If he had been the victor in his battle against Kurosaki Ichigo, what Bleach World would have become was an unknown question.
Holy Guardian Left Wing: "That really is a merciless assessment."
Angel Yan pursed her lips upon seeing Bai Xuan's words, but it was not difficult to see from them how highly he regarded Sosuke Aizen.
Oldest Godslayer: "If even Bai Xuan describes him that way, I'm becoming more and more curious about him."
Ordinary Group Owner: "He's pretty much as Bai Xuan described. Actually, there are quite a few characters in anime who can compare to Aizen. After all, they're all characters created by authors. Aizen just left a particularly deep impression on me."
Ordinary Group Owner: "Compared to Marquis Voban and Shendu, Aizen is definitely the more troublesome one!"
Shendu: "???"
Oldest Godslayer: "???"
Ordinary Group Owner: "Don't misunderstand, I'm not saying you aren't smart."
Ordinary Group Owner: "It's just... forget it. You'll understand once I upload Bleach's Memory Copy."
Su Yunqing did not know how to explain it either. She simply sorted through the memories in her mind and uploaded Bleach World's Memory
