Onigiri

A comedy series that pits the inhabitants of a Japanese sushi restaurant against a gaggle of greedy oni.

There was once an ogre (oni) mother who gave birth to human looking child. Instead of an ogre`s horn, this child was born with a sword in hand called the "Onigirimaru" or Ogre Slayer. He has no name and is only refered to by the name of his sword. Though he appears human, he is pure ogre. Believing that he will become human once all of his kind vanished fromthe world of humans, he sets out on his destiny to slay all of his kind. Even now, in the mother world of Japan, he is still out there slaying ogres. Description from ANN

Long ago, there lived a young man named Yosuke in the village of Shiiba in Hyuuga. "I want enough money and possessions to live a luxurious life without having to work" Yohei abandoned his job in his impoverished village, where only barnyard millet, oxtail millet and beans could be grown. He fled into the mountains, where one night he witnessed a strange sight. A blue ogre clinging to a large cedar tree split its back, began to shed its skin and quickly transformed into a red ogre. Yosuke stole the shed skin, wore it and began committing crimes in the village. However, when he tried to take off the skin, he couldn't get it off no matter what he did...

Over the centuries, oni (AKA demons of Japanese folklore) got a pretty bad reputation. Now it’s up to three plucky oni kids — sunny Tsutsuji, cool Tsuyukusa and boisterous Himawari — to improve human-oni relations through love, friendship and superpowered underpants! Note: Aired in 2 versions, a 60-episode 3-minute short series, and a combined 12-episode 14-minute TV series with the same content. Each episode of the combined version is 5 parts of the original.
