After transmigrating into the Monogatari world and going through incidents involving vampires, cats, crabs, snakes, and more, Nagi Tooma, who became a vampire, meets a deadpan angel, Evil God-chan, and others. He thought his everyday life was already eventful enough, until he met them.
Miko Yotsuya: "I can see ghosts."
Yayoi Hozuki: "I'm good at catching ghosts."
Kotoko Iwanaga: "I'm the god of ghosts."
Nagi Tooma: "I'm a ghost myself! Look, we're perfect for forming a band."
Miko Yotsuya: "..."
Yayoi Hozuki: "..."
Kotoko Iwanaga: "..."
"Then who is the little girl on your shoulder?" Kotoko Iwanaga pointed to the blonde vampire sitting on Nagi's shoulder, munching on a doughnut.
"She's our band's lead singer and mascot!"
