A horror manga about a boy suffering from nightmares.

The boys are tormented by nightmares (akumu) caused by scary stories they heard in elementary school.
But a baku eats the akumu and saves them.
Is the baku a good guy? Or...?

Three nightmares in one volume: "The Human-Faced Dog," "The Dashing Granny," and "The Red Cloak."
This volume compiles two works that were published in the 2014 children's magazine "Bessatsu CoroCoro Comic" with one new story drawn for this volume.
Relive those traumatic nightmares you accidentally read back then.
