((Even if you don't know Tokyo Ghoul, things will be explained!)) Yuuichirou Hyakuya has lost his entire family to the hands of ghouls--his mother and father, the rest of the orphanage, and his best friend, Mikaela Hyakuya. Taken in by a man who works for a special sect of the CCG, the Moon Demon Company, Yuu is placed in training to become an investigator so he can avenge his family, and is placed on a special elite squad of people like himself--Shinoa, who's entire family is a part of the CCG--Yoichi, his sister murdered by a ghoul--Mitsuba, trying to be like her sister--and Kimizuki, needing money for his sister's health. Mikaela Hyakuya struggles with the ghoul part of himself--half a creature that killed the rest of his family and no longer human, living as a ghoul under the protection of Krul Tepes, a ghoul who runs the café Sanguinem. Mikaela longs to be human once again, disgusted with the ghoul part of himself. Working at Sanguinem, he meets more ghouls--Lacus, who's afraid of starvation--René, experimented on by humans--Chess, her family killed by the CCG--and many more. Will Yuu ever run into Mikaela, discover that not only is he alive, but is now...A ghoul?
