Earthian

Earthian

Since the beginning of Earth's history, angels from the planet Eden have been carefully monitoring the behavior of its inhabitants, whom they call "Earthians." Chihaya and Kagetsuya are two agents sent from Eden to assess the positive and negative aspects of the Earthians' nature. Despite the orders Chihaya was given by his home planet, he frequently ends up entangled in Earthian affairs, much to Kagetsuya's annoyance. Meanwhile, as Chihaya tries to understand the origin of his strange black wings, he uncovers one mystery after another. Angels from the planet Eden have been watching Earthians, the inhabitants of Earth, for 5 billion years. Chihaya, an angel with unlucky black hair and wings, is a plus checker who travels to Earth with Kagetsuya, a minus checker. Each team of plus and minus checkers keep track of Earth events and, if the score ever reaches minus 10,000, the Earth will be destroyed. The story follows Chihaya and Kagetsuya and the different people and events they observe on Earth.
