Hozuki's Coolheadedness [2015]

Like most places on Earth, Hell is run by a bureaucracy. They have all the same problems as humans - internal disputes, staffing issues, and foreign relations problems. The only differences are the pools of boiling blood and screaming souls of the dead. And maybe a few other things...
Hozuki is the aide to King Enma, the ruler of hell. A bureaucrat with hundreds of years of experience, he solves problems with calm and a great big spiky club. In his spare time he enjoys fawning over cute animals and gardening.

Episodes are generally divided into two vignettes per episodes and it doesn't have a real overarching storyline, though it does have some connected story lines.

VideoTapeWorm.com says: Fans of Japanese animation have been howling for this release. Hozuki is a sadistic demon, Deputy Chief to King Enma, Lord of Hell,, who uses his fiendish talents to keep a lid on all the demons and lost souls who populate his wretched plane. But he also likes to play with fluffy little bunnies, and his favorite hobby is raising "Goldfish Flowers" (though we still don't understand exactly what those are). His guiding principal is simple: if any suffering is going to be done, it is not going be done by him. Truly unique, dark, mesmerizing and inventive.
