Short anime with up to 13 episodes: a weekend season

Erased has 12 episodes, Death Parade 12, Odd Taxi 13 and Cyberpunk: Edgerunners 10. These counts refer to the named series, not an entire franchise or extra material.

Short length does not imply light subject matter: Edgerunners and Death Parade contain mature content. Inspect the synopsis and platform age rating before planning a marathon.
