Ah, Rosario + Vampire. What a classic Harem anime.
To this day I still wish we got a reboot that fully followed the manga, as there's so much cool stuff that happens after where Season 1 ended.
Sure it was filled to the brim with numerous shonen action and harem cliches that were common at the time it was written, but I still want to see it all properly animated, especially Ghoul-Tsukune.

Still a kiss on the neck. That's a win !
