Rinka tries to save her friend Yui from being raped by the poolside, but Demura-sensei suddenly appears and stuns her with a stun gun. Still dazed, Rinka hears a familiar voice. She regains consciousness and the scene of Konomi being raped by Demura-sensei fills her vision. Rinka tries to save Konomi, but her body won't move because her arms and legs are restrained. Demura-sensei grows bored of using Konomi's body, and he approaches Rinka. Rinka gives him a defiant stare and tries to resist, but this only turns Demura-sensei on even more.

Who created the first anime?

Japan currently regards a 1917 lost film called Dekobou Shingachou: Meian no Shippai as the oldest confirmed domestic animation film.
[See my answer to What was the first ever anime made?] The man who created that film was Hekoten Shimokawa† (下川凹天).
He was born as Sadanori Shimokawa on May 2, 1892, on the island of Miyako-jima in Okinawa. At the age of 14, Shimokawa became a disciple of manga artist Rakuten Kitazawa, who had founded the manga magazine Tokyo Puck (named after the first successful humor magazine in the United States).
Shimokawa was later accepted into the prestigious Christian academy Aoyama Gakuin thanks to a recommendation from Kitazawa.
However, Shimokawa fell out of favor with artist after he dropped out of school a year and a half later. Kitazawa left Tokyo Puck in 1912 and began publishing a new magazine called Rakuten Puck, recruiting his old disciple once again.
While working for the new magazine in 1916, Shimokawa was introduced by an acquaintance to the film production company Tennenshoku Katsudou Shashin (Tenkatsu for short).
Knowing that Shimokawa was a manga artist, Tenkatsu producers invited him to work on attempting to create Japan’s first animation work. Shimokawa signed on to the Tenkatsu project with a monthly salary of 50 yen.
His drawing method was to draw using chalk on a chalkboard, erasing moving parts and redrawing them little by little.
The image was then photographed each time it was redrawn.
He later began employing sets of background imagery on which to draw and redraw his characters. Ironically, the pioneer of Japanese animation also caught the industry’s first occupational disease.
The light bulb used to capture photographs of Shimokawa’s animated frames caused him to develop an eye disease, and he had to be hospitalized for a year and a half.
Because of this, he left Tenkatsu after producing five works of animation in 1917. Shimokawa never returned to animation.
However, he continued working as a newspaper cartoonist and manga artist.
Shimokawa died in 1973 at the age of 81 and is buried in Tokyo. †His name is transcribed as “Outen Shimokawa” in the circle of anime historians, whereas “Hekoten Shimokawa” is used by manga historians.
The Kyoto International Manga Museum transcribes his name as Hekoten Shimokawa for its exhibition on the 100th anniversary of Japanese animation, which is the name I have used here.
