Youkai Gakkou no Seito Hajimemashita!

As the cherry blossoms fall, a new school year kicks off at Hyakki Academy—a school attracting youkai from all over Japan! Unfortunately, the first years are far from model students, especially the troublemaking idiot duo, Mamekichi Maizuka (a mame-danuki) and Tamao Akisame (a nekomata). It’s time for the lovable but rambunctious animal youkai to steal the spotlight in this spinoff comedy, set a year before the events of "A Terrified Teacher at Ghoul School!"
