So like the title says, I would like to discuss the rankings of the Youkai in Rosario + Vampire. I'm sure we've all heard about how there are monsters who are S-class like (Vampires, Werewolves, Pheonix, Youkos, etc.), but what is it really like for the rankings. Are they just rankings for the dangerousness for each species? Or is it the strength level of a particular monster. For example, in the anime, as crappy as it is, Issa is constantly mentioned as being beyond S-class, and Haji Miyamoto is mentioned to possibly be S-class due to being as strong as one.
So, I've come up with two ideas. The rankings are either:
A.) The average danger that can be faced for a particular Youkai species. Something like F, E, D, C, B, A for rankings that determine if the monster is extremely weak, or absolutely strong. S is obviously the extremely dangerous youkai that you should normally run away from. Or...
B.) The, to put it in familar terms for most anime fans, power level of the specific Youkai based on varying stats like speed, strength, how many same-level grunts in an army the guy can defeat in a set time amount of time, etc. For example, S- class could be being able to take out 1000 to 2000 of the same-level grunts, while beyond S-class is being able to beat more than 2000 of the said grunts.
What do you guys think?
