Croa Chimera  

クロアキメラ

Lucas' acquaintance, Will, who comes from a disadvantaged background, disappeared. The only clue Lucas possesses to locate his friend is their shared love for a specific club in the entertainment district where Yue performs. Although they had always planned to visit this place together, when Lucas went there alone, he was brutally assaulted. Fortunately, Yue discovered him and took him to her friend Takaomi for medical attention. It soon became apparent that Will had contracted chimera sickness, a condition affecting many people in the lower classes. Despite his determination, Lucas remains committed to finding his friend and saving him from this affliction.
