I like the PV's he's made^^. Favorites are Sparkle and Lady Dynamite
Mirrorcle world is also pretty good but feels a bit empty IMO.
It's sad that he so disliked around here, even though he is a bit creepy as stated above lol xD
EDIT:Just had to say that Kazu showing what moves ayu should make in making of Sparkle must be the most AWSOME thing
ever xDDD lol, I actually think he did them better than ayu herself.
