I’ve never seen Level E myself but now that it’s on sale for 40% off I have an incentive to check it out.
Tsutsui Yukitaka is a freshman who moved out of his parents’ home to live on his own, hoping to pursue a baseball team position at the new high school he’s attending. When he arrived at his new apartment however, he discovered that someone else was already inside—a young man who claims to be an alien and is suffering from amnesia.
The series is by Yoshihiro Togashi who is best known for his work on Yu Yu Hakusho and Hunter X Hunter. It’s produced by Studio Pierrot and David Production who are responsible for shows like Bleach and Soul Eater respectively.
