Prologue - Night and DayEdit
Shinya’s talent is recognized by one of the Order of the Imperial Demon kindergartens, and he is removed from his home and family. He survives by mastering spells, illusions, and fighting techniques. As he kills his friends and rival fiancé candidates over the years, he begins to constantly grin in order to keep calm and unnerve his opponents. At ten years old, Shinya wins the right to be bred with Mahiru Hiragi, and the Hiragi family adopts him as her fiancé. She meets him and rejects him because she is in love with Guren Ichinose, but they decide to pretend to be a couple in front of the Hiragi Family.
Chapter 1 - A Demon's PawEdit
It is mid-August. Mitsuki Iori uses herself as an experimental subject by injecting her left wrist with Guren’s demon-tainted blood. The hand transforms, leading Guren to amputate and then slay it when it suddenly grows into a monster and attempts to eat Mitsuki. Due to the wills of the occult researchers, Guren gives them permission for minimal human experimentation.
Chapter 2 - The Mice Will PlayEdit
It is August 20th, 2012. Guren recalls the love story 500 years ago that led the Hiragi Clan to scorn the Ichinose Clan. Shinya passes a note to Guren, stating that the Thousand Nights are going to meet at 2 a.m. at the tennis courts in Hikarigaoka Park that night. Norito, Shinya, and Mito invite themselves to Guren’s place to get all "chummy-chummy."
Chapter 3 - Demon and MouseEdit
Guren’s team plays shogi for the first time. Meanwhile, Yuichiro Amane’s mother appears on the news screaming about killing her demon child while her apartment is consumed by flames. She dowses herself in gasoline and attempts to light herself on fire, but firefighters tackle her to the ground before Saito appears and stops the broadcast.
Guren and Shinya arrive at Hikarigaoka Park on stolen motorcycles at 1:30 a.m. to witness a meeting of the Thousand Nights, but a vampire kills all eight members prior. Guren and Shinya barely manage to escape with their lives.
