Fucking great chapter.
Askin is really fun character in meta sense. He has always been that way in that he is not exactly the kind of character to go for shounen fight. He wants shortcuts.
And Urahara's bankai unlike everything else is STILL an enigma. Urahara just uses it, which is brilliant in meta sense.
Its also interesting of how much it relates to Mayuri - Mayuri's obsession is mutilating and changing his body. We KNOW that his real self looks very similar to Urahara and we KNOW he wants to surpass him, so its an interesting connection.
Overalla strong 5/5 chapter.
