Hozuki's Coolheadedness Volume 10

In this tenth edition, Hozuki is invited to give a presentation at an elementary school, fills in at a mixer at the behest of Karashi, investigates a group of ogres terrorizing the mortal realm, and even has to deal with Haruichi, a spy from the Eight Cold Hells. As if he wasn't busy enough, Hozuki still finds time to drop by European hell to give Satan a piece of his mind for sending King Enma a most offensive missive!
