Reijou Kanteishi to Garou no Akuma

Riz, an earl's daughter and art enthusiast, is approached by John, a temporary gallery manager hired by her uncle, who proposes a contract. John's request is not for love, but to use Riz's "Holy Eyes"—a rare ability to see demons hidden in paintings. Forced into an agreement with John, who is actually a demon, Riz unexpectedly turns the situation around by declaring her intent to own him instead. The story follows the unusual dynamic between Riz and John as their relationship develops.
