The Uncle From Another World anime has released its first trailer and unveiled a July release date. Additionally, several character visuals were released.
Uncle From Another World is based on the Kadokawa-published manga by Hotondoshindeiru, which began in 2018 and has seven tankoubon volumes as of February 2022. It is serialized on Web Comic Apanta and published under the MF Comics label.
Yen Press describes the manga as:
Seventeen years ago, Takafumi’s uncle fell into a coma, but now he’s back like a man risen from his grave. Soon, Takafumi discovers two bizarre things: His uncle treasures video games above all else, and, while comatose, he was actually transported to another world as some heroic guardian! Now, not only does Takafumi have to room with an uncle who is literally magical, he also has to catch the guy up on two decades of history—smartphones, high-speed internet, modern anime tropes…and the traumatic outcome of the ’90s console war!
The main staff includes Shigeki Kawai (Blue Exorcist assistant director) as director, Kenta Ihara (Mieruko-Chan) as series composer and scriptwriter, and Kazuhiro Oota (Natsu no Arashi!) as character designer. Atelier Pontdarc is the animation production company. Meanwhile, the main cast includes Takehito Koyasu as Ojisan, Jun Fukuyama as Takafumi, Mikako Komatsu as Fujimiya, Haruka Tomatsu as Elf, Aoi Yuuki as Mabel, and Aki Toyosaki as Alicia.
