Earthian - S01

Since the beginning of Earth's history, angels from the planet Eden have kept a close watch on its people, whom they call "Earthians." Chihaya and Kagetsuya are two agents sent from Eden to weigh the good and bad sides of the Earthians' nature. Even though Chihaya was given orders by his home planet, he often ends up caught up in Earthian matters, which annoys Kagetsuya. Meanwhile, as Chihaya tries to understand where his strange black wings came from, he uncovers one mystery after another.
