Description:

After fainting at work, a young lady awakens in the back room of the café she works at with no memory of her life or those around her. Two of her friends, whom she soon learns are named Shin and Toma, are called to help her get home safely. Once she is alone, she meets a spectral boy named Orion that only she can see and hear. He explains that she lost her memories because of his chance visit to her world, so he vows to help her remember who she is. However, regaining her departed memories without worrying those around her may be more difficult than she realizes. In addition to the gloomy Shin and the protective Toma, she must be wary of arousing the suspicions of the captivating Ikki, the quick-witted Kent, and a mysterious man who lurks in the distance. As her amnesia entangles her in the lives of each of these men, her fragmented memories return piece by piece, and the mysteries of her circumstances slowly come to light. [Written by MAL Rewrite]

Ritsuka Tachibana has always been a good student, so she is completely shocked when she is suddenly summoned by the student council. Even more, they seem to think of Ritsuka as a troublemaker. Led by the handsome Rem Kaginuki, the student council—also consisting of Urie Sogami, Shiki Natsumizaka and Mage Nanashiro—tries to question her, but it soon becomes clear that they have ulterior motives. However, this is only the beginning. When her mother gets kidnapped, her life is turned upside down, and Ritsuka gets drawn into a world of vampires and devils. Both groups are searching for the "Grimoire," a forbidden item allowing its owner to rule the world. The return of her brother Lindo from overseas gives her hope, but even he appears to be hiding something. In a world filled with secrets, Ritsuka questions whom she can trust in this dark musical tale, while the handsome and dangerous members of the student council compete for her attention.
