Level E (レベル E) is a Japanese manga series written and illustrated by Yoshihiro Togashi. The plot follows the misadventures of alien Prince Baka Ki El Dogra, who crash-lands on Earth and forcibly begins living with high school student and baseball player Yukitaka Tsutsui. However, Prince Baka gradually realizes that he is targeted by aliens from other planets, and he uses his clever wits to somehow maintain world peace each time. Along with its short length and more realistic art style, the story of Level E focuses much more heavily on humor than Togashi's more famous series Yu Yu Hakusho and Hunter × Hunter.
Level E was serialized for sixteen chapters in Shueisha's manga magazine Weekly Shōnen Jump from 1995 to 1997 and collected in three volumes. A 13-episode anime television series adaptation, directed by Toshiyuki Katō and produced by Pierrot and David Production, aired on TV Tokyo in 2011.
