Caste Heaven manga volume 4 features story and art by Chise Ogawa.

Ever since Karino betrayed him by dragging him off his kingly throne, dropping him to target, Azusa has sworn revenge. But as he’s planning his next move, he’s approached by shy geek Inugai, who’s taken a rather sudden—if odd—interest in photography. What are Inugai’s true motives? And is revenge really what Azusa seeks?
