SPOILERS FOR ROSARIO+VAMPIRE AND ASSASSINATION CLASSROOM

For people who don't know Rosario+Vampire is my favorite manga and I really wish it was more popular. I mean it would probably be more popular if the anime had done the manga justice, it so needs the FMA Brotherhood and Fruits Basket treatment.

But anyway, onto the actual idea. I like all of the snake imagery found with Nagisa throughout Assassination Classroom, so imagine a naga Nagisa in the story of R+V. (I know that there are no nagas in Rosario, but there is a lamia and that is good enough)

I just love the idea as a whole because this series has so much potential with crossovers, maybe I am biased but whatever. Plus you could easily add other characters from Assassination Classroom in this case, because that would be fun.

Sorry, crossovers are some of my favorite things to find within a fandom. What people decide to do with them is just so much fun, in this case, Rosario+Vampire deserves more fans and that is that.
