FLCL is a 10 for me and the only standalone show (or "first season" for that matter, not that I plan to see the Adult Swim FLCL revivals) to get that score from me
Although Kill la Kill was really close, I think that and Bakemonogatari are the only shows I'd consider bumping up to a 10
Not changing this part until Saki Amamiya (or Isa Jo) gets into Smash as a playable character
Now watching: Urusei Yatsura 2022 S2, Nichijou
