The original Pure Pure Purea Desu comedy anime shorts featured super-deformed characters, and each short aired after the AT-X network’s broadcast of each episode of the main Overlord television anime series in 2015.
The shorts also streamed online, and then shipped with the Japanese home video releases of the main Overlord anime.
The Overlord anime’s main cast reprised their roles for the anime shorts.
The 13-episode Overlord television anime series premiered in Japan in July 2015.
