The "Yarō yo! Shironeko Project 5-Shūnen Kinen Special Nama-Hōsō" (Let's Do This! White Cat Project 5th Anniversary Special Live Stream) event debuted the first teaser promotional video and visual for the television anime of Colopl's Shironeko Project smartphone game on Saturday. The video announced the anime's main staff, main cast, Shironeko Project: Zero Chronicle title, and April 2020 premiere.
Masato Jinbo (Fate/kaleid liner Prisma Illya 2wei!, Chaos;Child) is writing and directing the anime at project No.9 (The Ryuo's Work is Never Done!), and Yousuke Okuda (Sword Art Online the Movie: Ordinal Scale animation director, Is the order a rabbit?) is designing the characters. Taku Iwasaki (Bungo Stray Dogs) is composing the music. The franchise's Hiroki Asai (Colopl) is serving as executive producer of the anime, and the game's director Ryōji Tsunoda is serving as the anime's supervisor.
The cast stars:
- Yuuki Kaji as Yami no Ōji (Prince of Darkness)
- Yui Horie as Hikari no Ō Airisu (Queen of Light Iris)
As the anime's title indicates, the anime will adapt the "Zero Chronicle: Hajimari no Tsumi" (The First Sin) prologue event that commemorated the game's third anniversary.
Colopl's Shironeko Project smartphone game launched in Japan in 2014, and launched in English with the title Rune Story in 2015. The game's English version ceased updates in 2016. The 3D action RPG features real-time battles and players can team up together in groups of four to take on foes. City building is also a prominent aspect that can affect how players' characters grow.
The game was ranked one of the mobile games fans most want to have an anime adaptation on a survey by Famitsu App last year.
Nintendo filed a lawsuit against Colopl in January 2018, alleging that Colopl infringed on at least five Nintendo patents in Shironeko Project. Nintendo is seeking 4.4 billion yen (about US$40 million) in damages and a suspension of Shironeko Project. Nintendo clarified last July that the lawsuit is a separate matter from its games software business and will not affect Shironeko New Project. The court hearings are still ongoing for the lawsuit.
