Kaya-chan Isn't Scary

Kids and ghosts. When young Satsuki finds an old book of spells from her passed away mother, she gains the power to fight ghosts that are haunting her new school. With the help of her friends, and of a really wicked devil cat, she must protect everyone around her or be haunted for ever more.

The story of the anime revolves around Hanako, a girl who lives in a supernatural world apart from our own. Hanako appears when schoolchildren are in trouble; she is a benevolent version of an enduring Japanese urban legend about Hanako, a ghost who lives in a toilet at the local school.

The horror comedy manga begins one fateful day when the cowardly (unnamed) protagonist meets Mechako, the leader of the "Kaikigumi" organization which is in charge of the ghosts and supernatural creatures scaring humans. The protagonist somehow takes part in the revival of the Kaikigumi, after which one bizarre (yet not scary) phenomenon after another crops up around him.

Rookie teacher Haruaki Abe is as cowardly as they come. It's hard enough for him to handle human students without whimpering-and now he's going to be teaching at a school full of monsters?! It's a classroom of horrors for Haruaki, as his mischievous students use every means at their disposal to prank him! Will this poor teacher be able to get his group of ghouls under control, or is this class destined for failure?
