What's Sumi-e?

Sumi-e is one of the East Asian styles of traditional brush painting. While it's monochrome, it can express rich and impressive scenes. Watch these drawing videos and you'll find what it is.

What's ONI?

ONI are Japanese demons with horns. They have been popular stock characters in Japanese fairytales, manga, film, art, literature, theatre and so on for a long time.

And the lead of this film has these horns too, even though she is not an ONI. You will be able to see the reason why she has horns and discover the meaning of "Operation ONI" at the end of story. It's a military operation concerning her.

Synopsis

This is a fictional story about Japan when there were "samurais".

A war is about to break out between humans and the Empire of Spirits. Mao, the strongest samurai with ONI horns, had been separated from her parents by death and was raised by the tyrannical lord.

Mao is human, but because of the demon horn on her head, she is not considered human. She has always felt lonely.

Only her best friend, Onatsu, was able to save her from her loneliness. Filled with Onatsu's family-like love and affection, Mao felt happy for the first time in her life.

Then, a war begins between humans and monsters. Mao wants to protect both their country and Onatsu, but Onatsu says, "This is the end of our friendship." She bursts into tears and disappears.

What is the true meaning of Onatsu's words?
And what will become of their friendship?

The truth is hidden in Mao's mysterious horns...

Ever since she was a little girl, she loved singing and drawing. Her teacher was a cathode-ray tube TV that was still in black and white. Atom, Sally, and Leo, the Jungle Emperor, appeared on it. It was her awakening to drawing. She found a ballpoint pen and drew her favorite characters on the back of the flier, excitedly enjoying the world of cartoons. She has experienced many things in her life, but now she is feeling as if she is in the same space as she was back then. She is sure that it is a blessing that she was able to meet Director Takane, the Ink Dancer Animation Team, and all the staff of Studio ONI, Operation ONI, as she approaches the milestone of her 60th birthday this year. She will cherish this relationship and continue to support Operation ONI. (Twitter(x))

Thanks to all of you, our crowdfunding campaign for the first 15 minutes (Episode 1) in 2022 ended successfully on both Kickstarter and CAMPFIRE. Thank you from the bottom of our hearts for your warm support!

The first 15 minutes (episode 1) is currently in production. The release of Episode 1 and the next crowdfunding campaign are scheduled in the first half of 2025 or later.

The length of the film is approximately 60 minutes. Since we do not have a large production team, it will take about 5 years to complete the film. We feel bad about keeping you waiting for a long time, so we decided to divide the film into 4 episodes and produce and release 15 minutes of each part every year (12-15 months). In the scripts, I created a climax and a cliffhanger every 15 minutes , so this anime can be enjoyed either in full version or in small 15-minute episodes. This way, our supporters will be able to enjoy our film every year or so. Our first goal is to combine these four episodes into a single movie and bring it to film festivals in the U.S. We would like to walk the red carpet. It is our dream. Thank you very much for your cooperation.
