Not sure if any costume can overtake Olympics Seimei for me haha
(Now that I think about it, I'm quite torn between a number of Yuzu's outfits other than Olympics Seimei being number 1 for me, the number 2 spot will have to be shared by Origin, Chopin 1.0, Olympics Chopin, purple LGC, Etude, POTO 2.0, R&J 1.0, Swan and all black UA )
(side note: the see-through black mesh gloves he wears for Origin is giving me way too many heart attacks. it's bad for my health )
