Kakashi's Ultimate Sexy Jutsu (KakaSaku Manip)
I already made a KakaHina manip (which is a pairing I don't even fully support). So making a KakaSaku one just seemed obvious. To answer your most obvious questions:
1. The shirt clips AREN'T from the Naruto series. They're frrom the swimming anime "Free!".
2. The song is "Cliche" performed by Cassie Steele.
3. The sound clip at the end is from "My Little Pony: Friendship is Magic". The line was originally spoken by Rarity (not sure which episode, though).
4. If you don't like KakaSaku and are about to post a rude comment, go away. Find some nice anti-KakaSaku video which would be better suited to your comment.
