Goblin Night

A phenomenon called "Goblin Night" occurred six years ago, granting one in every hundred people the ability to transform into a creature known as a "goblin." Unable to control or respond effectively, authorities failed to stop some goblins from using their powers for harm, leading to societal breakdown. In modern-day Japan, Mamoru and Yuki, both goblins, work to defend their town. Mamoru, however, is reluctant to trust or help others due to the events of Goblin Night, which resulted in his brother's death. The situation worsens when the person responsible for his brother's death arrives in town.
