" I always thought the kid versions of the One Piece characters were adorable. These aren't just "chibi" parodies but what the cast looked like when they were children.

" i expect urahara to show up and tell ichigo that he has a way to get his powers back but that it will take like 2 years and then timeskip and end of chapter. However, I want it to just skip like 20 years into the future and have some shenanigans happen that ichigo gets caught up in and then he finds his powers are back or whatever. "A 20 year time skip would be mind blowing but we can only hope.
