Luner is the first creation made by star other than light. Although he's in charge of eternal punishment, he's actually on good terms with star, having a romantic relationship with her.

Motives

Luner's job is to tempt and punish bad people to keep them from wrongfully entering heaven, Luner's powers are often limited by star, requiring him to have written agreements to use them. He's mostly restricted to interacting with humans though mirrors. He is easily containable with red string or salt, and uses strings himself to keep contractually obligated people in check.

When a saint named Claire was sacrificed to him, he took it upon himself to take care of her as his daughter. after 3 years, Stella decided Claire should be with the living. Luner wasn't a fan of having this poor girl back with the people who killed her.
