## Plot

An ogre-like demon and former human Hozuki (鬼灯, Hōzuki) works as Chief of Staff under King Enma (閻魔大王, Enma-Daiō), the King and Head Judge of Hell, who determines what kind of hell the dead will be sent to. The serious-minded Hozuki attempts to manage and troubleshoot unusual problems that occur in the Japanese hell. Two of Hozuki's most prominent subordinates are Karauri (唐瓜) and Nasubi (茄子). Other characters in the underworld include Okoh (お香, Okō) the chief assistant of Mortal Hell; Mustard (芥子, Karashi), the rabbit from Kachi-kachi Yama, who acts cute but snaps when someone says Tanuki/Raccoon or acts as one; Peach Maki (ピーチ・マキ, Pīchi Maki), a famous idol in Hell and Hozuki's acquaintance; and Yoshitsune Minamoto (源義経, Minamoto no Yoshitsune), a commander in the Crow-Tengu Police. Hozuki's main rival is Hakutaku (白澤), a Chinese medicine expert who works at Shangri-La. Hakutaku is assisted by Momotarō (桃太郎), who was a famous samurai in life. Momotaro's pets Shiro (シロ) the dog, Kakisuke (柿助) the monkey, and Rurio (ルリオ) the pheasant are also regular characters in the series, working as torturers in the animal cruelty section of hell. In the second season, more characters are introduced such as the original Chief of Staff Izanami-no-Mikoto (伊邪那美命), Miki (ミキ, Miki) an Idol signed in Maki's Idol office and Hozuki's Twin Zashiki-warashi adopted daughters.

## Production

In 2010, Natsumi Eguchi won the Honorable Mention Award of the 57th Chiba Tetsuya Awards for Hinichijōtekina Nanigenai Hanashi (非日常的な何気ない話, lit. "An unusual casual story"). This work's character Oni (鬼, lit. "Ogre") was the model upon which Hozuki, who would first appear in the Morning's 32nd issue of 2010 with the story Jigoku no Sata to Are ya Kore (地獄の沙汰とあれやこれ, lit. "The State of the Hell, and This and That"), was based. The series was later renamed Hōzuki no Reitetsu and the magazine started to serialize it.
Eguchi developed a liking for yōkai manga such as GeGeGe no Kitarō and Akuma-kun because of the influence of her parents, whose "strange" preferences for these instead of the typical girl's manga and battle manga lead Eguchi to say she "has been reading only afterworld yōkai books since [she] can remember". The horror-themed series The Laughing Salesman and the Japanese folktales-based Manga Nihon Mukashi Banashi [ja] also influenced Eguchi, who attributes this childhood experience to her mother being a classical studies professor, and as such she had access to several mythology and folklore books, one of which was Shigeru Mizuki's compilation of 101 yōkai stories. Eguchi highlighted the influence of the anime adaptation of Mizuki's GeGeGe; she appreciated the characters' scary-but-cute features and their variety in each episode. Other non-horror works, including Doraemon—especially the main character's bossy personality in the "insane" manga as Eguchi dubbed it, rather than the educational anime, also influenced her.

### Critical response

The 2012 edition of Takarajimasha's Kono Manga ga Sugoi!, which surveys people in the manga and publishing industry, named Hozuki's Coolheadedness along with I the nineteenth-best manga series for male readers. In 2012, it was one of the 15 manga nominated for the 5th Manga Taishō, and a jury selected it for the 16th Japan Media Arts Festival Awards. The series was nominated for the 38th Kodansha Manga Award for Best General Manga, and Media Factory's Da Vinci ranked it fifth on the "Book of the Year" in 2014. It also ranked 25th, 37th, and 47th on Da Vinci's "Book of the Year" in 2018, 2019, and 2020, respectively. In 2021, the manga, along with Kimi o Shinasenai tame no Storia by Toriko Gin, won the 52nd Seiun Sci-fi Award for Best Comic.
Several reviewers named Hozuki's Coolheadedness' first season among their favorite anime of 2014 or of that winter season; this include Vichus Smith of Electronic Gaming Monthly, Seb Reid of UK Anime Network, Kelly Quinn of Tor.com, and Amy McNulty and Gabriella Ekens of Anime News Network (ANN). Most reviewers pondered over its humor, which requires some understanding of Japanese culture, but ultimately appreciated it. Quinn considered it to be one of the year's most original comedy shows because of its "sadistic humor and bizarre setting". Ekens said; "While not every episode provoked peals of laughter, there was just enough cuteness and cleverness aside to make me love this little show". Reid compared it to Polar Bear Cafe because of its "dry, sarcastic" humor style and "weird" stories, and praised the writing for its peculiar stories and dialogues, as well as its "deadpan acting". Josh Tolentino of Japanator often compared it to Lucky Star for its slow pace. He commented; "I've heard rumblings in some circles about [the anime] being intensely boring, but I'm having fun so far. It's just really low-key in the way that, say, Dilbert is low-key." Nicole MacLean of THEM Anime Reviews also found it similar to Dilbert and salaryman manga, especially on the depiction of Hozuki–Enma relationship.
ANN's Carl Kimlinger found the series generally unfavorable; although he noted its premise as singular, he criticized its music, characters and "comedic incompetence". He nevertheless praised its sumi-e-inspired visuals, which are "startlingly beautiful at times, and utterly distinctive at all times". Quinn also praised the series for its visuals, while Tolentino stated "one of this show's best qualities is how it shows off traditional Japanese art". Browne commended the series' mixture of modern character designs with classic art style that creates a "unique and appealing look", and said "the animation is generally quite good, if low-key". Kate O'Neil of The Fandom Post also praised it, stating "the animation is quite superb" and "It's the weird artsy kid sitting in the back row of desks combined with The Office. Many viewers won't get the appeal, but it's always been a fascinating and often funny watch with a great artistic style and well defined personalities."
