Kubo has taken a leaf out of Kishi's mangaka-let and decided to make the 7 & under crowd his main audience. That's why. Also, let's go ahead and break it down: Gin is the poor man's Itachi. Itachi, the most well-done character and story arc that Kishi ever did or will do. Water down Itachi's story and this is basically it. Aizen on the cover of Volume 12. Sōsuke Aizen (藍染 惣右介, Aizen Sōsuke) is a fictional character in the Japanese manga series Bleach created by Tite Kubo. He is the main antagonist of the first half of the anime adaptation, as well as the most significant one for the entirety of the adaptation. He is the captain of the Fifth Division Sōsuke Aizen is the former captain of Division 5 of the Gotei 13. With his followers, Gin Ichimaru and Kaname Tōsen, Aizen committed treason and left Soul Society for Hueco Mundo so he could become the ruler of both worlds. His lieutenant was Momo Hinamori. He formerly served as the lieutenant of Division 5 under Shinji Hirako. With Aizen asking her how she has been, Hinamori expresses disbelief at seeing him again after thinking he was dead, but Aizen simply notes that he is clearly alive. Walking up to Aizen, Hinamori grasps his haori and begins to tear up, leading Aizen to apologize for how heartbroken she must have felt as he caresses her head. Internally Shinji Hirako (平子 真子, Hirako Shinji) is the captain of the 5th Division in the Gotei 13. His lieutenant is Momo Hinamori. He also served as a recruiter and the de facto leader of the Visored. He was also a captain over 100 years ago prior to his exile and was reinstated to his old post sometime after the defeat of Sōsuke Aizen . So basically, Aizen wouldn't normally draw his sword. Even if he would, he would instantly kill Gin if he uses Bankai so Gin waited for the opportunity to be able to use Bankai without being suspicioned. I know he can make his sword look the same in Bankai but Aizen would realize the change in Reiatsu. This debate actually stems from a point in the series when Soi Fon strikes Aizen with her shikai and goes in for the kill. As stated by the series, Soi Fon’s zanpakuto instantly kills an opponent it strikes multiple times. However, Aizen tanked this and was completely unaffected. Hence the discussion. Let’s get into the specifics of Soi Fon Well, it was a perfect moment to take out the trash and torture some more people. Literally, Aizen is an asshole. In Tousen's point of view, as well as anyone who knew him well, it might as well been a mercy kill. But for Aizen, I'm sure he was just doing it to cut some hanging strings and to cause more pain. He might be telling the truth, but jh5ESHQ.
