What in the world is Hozuki doing when he visit the mortal realm? How do Hell's ogres feel about Setsubun? Is it just me, or do a lot of ogres have curly hair? Why is King Shinko's personal aide the Heian noble Ono-no-Takamura? Are there dinosaurs in Hell? Find all of that out and more in volume 6! And at long last, Hakutaku's age is revealed!

The Jizo is an avatar of King Enma? There's a special hell for sending an elephant on a drunken rampage?! Learn these and other veritably useless Hell trivia in this eventful edition! We've got a goldfish plant pageant, a day in the life of Shiro, a look into Hell management, and much more! And what's this? It turns out Hozuki is actually King Enma's second aide?!

Whether it's Cow-Head or Amanosagume, Hakutaku is a lover of all women! But have you ever wondered just where he draws the line? At the court of the machine maniac King Henjo, we'll get a first-hand look at his next-in-line chief of staff, the mechanical Memeko-chan! Next, ever the derrière devotee, the man-faced dog catches a few hands when he goes around sniffing one too many rears! And at long last, Hozuki's beloved goldfish plants bloom! An event so momentous, it made the cover! Ogyaaaaah!

The mural of Enma Palace is crumbling! Families are offering too many oblations to the dead! Beelzebub’s wife and master seductress Lady Lilith visits Japan from the West! There is no problem that Hozuki can’t solve. Well, apart from constant headache Hakutaku gives him, perhaps.

What more is there is to say about the main character's sadistic tendencies? We've got Lurio the pheasant, the most humble of Momotaro's companions; Oiwa the lantern from the Yotsuya Kaidan, who hasn't appeared since volume two; Kama, the designer, who appears...surprisingly often; and even Hageito of the Records Section, who briefly appeared at the end of the last book. Volume seven's all about side-characters, and they're here to shine!

More Mao Hao Hao, more fun! Volume 12 marks a huge milestone with the series' 100th chapter! In this monumental edition, Hozuki shows great interest in the legends surrounding King Enma, while the others show great interest in the antics of a 15-year-old (in human years) Hozuki, skipping class to check out a cursed club. Meanwhile, half for business, half out of morbid curiosity for cruel fairy tales, Hozuki heads to Heaven to have a chat with the goats of The Wolf and the Seven Young Goats. And at long last, the names of Hozuki's two lifelong friends are revealed!

Volume eight opens appropriately with a tale of the Eight Cold Hells! In this edition, we review the similarities between the Greek and Japanese underworld, eavesdrop on King Enma and King Shinko grumbling about their respective aides, sit in on a conversation between Hozuki and Hakutaku on the intricacies of badmouthing, and get a peek into the life of Kakisuke. Volume eight, now with nine laugh-packed chapters!
