Earthian

Chihaya and Kagetsuya, two angels from the planet Eden with completely opposite personalities, are sent to Earth to record the good and bad deeds of its people, the Earthians. If their tally reaches 10,000 negative checks, the planet will be doomed. Among many angel pairs assigned to judge Earth, Chihaya and Kagetsuya start off constantly clashing, but over time, they form a unique bond between them.
