Dorohedoro Vol. 5 (manga)

Everyone is looking for that special someone... Convinced that Risu is the key to his past (and his head), Caiman heads to the Sorcerers' dimension on his own. While he's tracking down Risu, he finds the Sorcerers getting ready for “Blue Night,” a festival where Sorcerers find their partners. Meanwhile, Risu is looking for his old partner Aikawa to see what he might know about the people who killed him. Shin and Noi are both being hunted by Sorcerers who've long coveted them as partners. En is relentlessly hunting a Sorcerer who can manipulate time. And Fujita's looking for...well, any partner who will have him.
