Far away from the realm of humans, Youkai Academy reigns in all of it's spooky goodness!

As humans currently control the world, the main purpose for Youkai Academy is to teach young monsters to blend in with humanity. As a school rule, every student and teacher must keep their true nature masked by some form of sealing, so it may be hard to believe that each and every person (well... except for Tsukune Aono...) in this school is a monster!

But! Something strange is going on in Youkai Academy: Some of the students are starting to get sluggish and fat! So, pick a main character from the series and let their gaining adventure begin!
