The official website for Ninja Slayer From Animation began streaming a teaser trailer for the upcoming anime on Sunday. The trailer premiered at Anime Expo on Friday.

Akira Amemiya (Inferno Cop) will direct the series at Studio Trigger. Boom Boom Satellites (Xam'd: Lost Memories, Mobile Suit Gundam UC) will perform the main theme song "Back in Black."

The "cyberpunk ninja action drama" is set in the near-future city of Neo Saitama, where ninja souls have been unleashed. The story follows Kenji Fujikido, a salaryman whose wife and children were killed in a ninja battle. He is then possessed by a ninja soul and becomes a ninja slayer, devoted to killing all ninja to avenge his family.

The story was originally posted piecemeal on Twitter by Japanese "translators" Honda Yu and Sugi Leika, allegedly translating the work of American authors "Bradley Bond and Philip [email protected] Morzez." After the story grew in popularity, Enterbrain published the first Japanese-translated volume in print, Ninja Slayer: Neo Saitama in Flames , in September 2012. The story then inspired three comic adaptations from Enterbrain and Kodansha, as well as an audio drama with Toshiyuki Morikawa as the title character.

Tokyo Otaku Mode is releasing the first two novels online in English. The company is also releasing a manga version online in English.
