ウィ キャン フライ!

In an attempt to end his tedious and pointless everyday existence, high school student Sei threw himself off of a roof. Instead of falling to his death, he found himself transported to a different world, where all people had wings. During the public's general shock at the arrival of a wingless man, Sei is rescued by a black-winged girl named Sakura, who lives with a community of citizens with inferior wings.
