User blog comment:Xilinoc/Ch. 685 - THE PERFECT END/@comment-28131457-20160804150111

I would to point out that Ichigo, Uryuu, Orihime, Sado, Aizen are absent from this chapter, the characters that are not exposed to Kyoka Suigetsu's effect, and the characters that are living, not souls(except for Aizen)

Kyoka Suigetsu in a way creates an illusion of an alternate reality, what if the Bankai CREATES another reality? Maybe the destruction of Yhwach by Ichigo caused the soul universe to shatter, and only the real world could remain. Maybe with what's left of Aizen's life, he asks if Ichigo would chose to let his friends continue to live on another reality, or die with the current one.

A lot of speculation and theory here, I know, but I'm just skeptic with this whole Perfect Happy Ending of this chapter.
