We Can Fly!

Seeking an end to his monotonous and futile life, a high schooler named Sei leapt off a rooftop. However, rather than meeting his demise, he was suddenly hurled into a new realm where each individual possessed a set of wings. As society was shell-shocked by the appearance of someone without wings, Sei was fortunately saved by a black-winged young woman named Sakura, who resided with a group of people possessing less-than-desirable wings.
