A Dark Rabbit Has Seven Lives (いつか天魔の黒ウサギ, Itsuka Tenma no Kuro Usagi, lit. The Devil's Black Rabbit of an Unknown Time) is a Japanese light novel series by Takaya Kagami, with illustrations by Japanese-Brazilian illustrator Yū Kamiya. The series includes 13 novels published by Fujimi Shobo between November 2008 and December 2013. The series also has a spin-off series, Kurenai Gekkō no Seitokaishitsu (紅月光の生徒会室, Gekkō Kurenai's Student Council Room), which has five volumes since February 2010. A manga adaptation by Shiori Asahina started serialization in the shōnen manga magazine Monthly Dragon Age on October 9, 2009. A 12-episode anime adaptation aired between July and September 2011.[1]


Kurogane Taito is a freshman in Miyasaka High. Ever since an injury to his leg (a snapped tendon) that prevented him from practicing karate, which he had excelled in since elementary school, he has always believed that he was an ordinary, regular guy. However, due to a promise exchanged with a beautiful Vampire (Most Ancient Sorcerer) Saitohimea nine years ago which he has forgotten about, he is in fact no longer ordinary. Nine years ago, Saitohimea injected him with a poison, which prevents him from dying as long as he doesn't die seven times within fifteen minutes. Shortly after his change, a boy named Kurenai Hinata attacked them with a demon and killed Taito six times in rapid succession. In order to prevent him from killing Taito outright, Saitohimea agreed to leave with Hinata and allow Taito's memory to be wiped. Subsequent to this, Saitohimea was experimented on and imprisoned in a dimension with no sound or light whatsoever, and Taito continued with his life as a normal human.

Taito has recently been having a recurring dream concerning Saitohimea, although he is unable to remember her name. After saving Andou Mirai from being hit by a truck he is himself killed, however due to his conditional immortality, he survives. After his body picks up and reattaches his head, he begins to remember more details about Saitohimea and eventually recalls her name, which allows Saitohimea to regain her powers and escape from her prison. By this point, Taito has realized that not only are his most recent injuries healed, but his previous leg injury is also healed. He is attacked by the Church but is able to survive and he makes his way to the playground where he and Saitohimea met previously, where they are reunited.

Along with unlikely allies, Kurenai Gekkou, Miyasaka High's student council president and genius who is bent on avenging his parents as well as Andou Mirai, Gekkou's cute lightning demon familiar, Taito and Saitohimea have to contend against Gekkou's younger twin brother, Kurenai Hinata, who seeks to resurrect the powerful Vampire (Most Ancient Sorcerer) Bahlskra. Unknown to them, their destinies were already woven and foretold in an ancient prophecy of epic proportions.


Taito Kurogane (鉄 大兎, Kurogane Taito)
Voiced by: Yūki Kaji (drama CD), Shinnosuke Tachibana (anime)
A light-blue hair 16-year-old freshman of Miyasaka High, the protagonist of the story, Kurogane Taito used to excel in karate when he was young, but later had to give it up due to a leg injury. Since then, he had believed himself to be an ordinary, regular guy. However, his memories of an event nine years ago were sealed up, during which he had made a contract with the beautiful Saitohimea and acquired an extraordinary ability which grants him a conditional form of immortality. At the start of the story, he manages to regain those memories after a certain incident and goes on to reunite with Saitohimea. He later acquires further powers and swears to protect Saitohimea from the Tenma (天魔). One of the powers he acquires is a familiar in the form of a cat, this familiar, called Nyankichi, required a certain amount of blood to be summoned which was impossible for a normal human to give without dying. The familiar enabled him to cast spells which allowed him to see in the dark as well as a magic which curses other magic, therefore sealing them. While Tenma is normally translated as evil spirit or demon, in the story, it is a special existence different from the conventional evil spirit. He gradually remembers the feelings he had for Saitohimea and realizes he is falling in love with her as she is with him.

Since she was born, everyone around her has sought and hunted her for her powers, except for Taito, whom she fell in love with and subsequently formed a contract with. In order to revive the dead Taito, she exchanged most of her powers in order to revive him, but still retains a large amount compared to humans. She later joins Miyasaka High as a student, and together with Taito, becomes part of Gekkou's student council and takes on the name of Himea Saito.

Voiced by: Daisuke Ono (drama CD), Yūichi Nakamura (anime)
Kurenai Gekkou, a freshman and also the student council president of Miyasaka High, is a self-proclaimed genius. Nine years ago before the starting tumeframe of the story, due to a certain deed committed by his younger twin brother, Hinata, Gekkou was prompted to constantly seek out power, initially driven by the fear for his life, and later motivated by the prospects of revenge. Gekkou is demonstrated to be quick-witted and highly intelligent. He wields an ancient fencing-like sword known as Spell Error, and is trained in several traditional arts of exorcism. As the student council president, he has made a contract with the lightning demon Mirai and is tasked to be the guardian of the Holy Ground (聖地)( a location with certain special properties over which Miyasaka High was built).

Initially tasked to kill Gekkou, she later went on to form a contract with him as she became unable to release her powers without his consent. While she is considered to be an upper-class demon of noble blood, most of her powers are usually sealed away by Gekkou and can only be re-activated with his permission, upon which her hair will turn golden and her body will be wrapped in a vortex of lightning. She is described to be excessively boisterous and annoying to Gekkou, though on the flip side, she is often irritated by Gekkou's apparent indifference to her existence. Her favorite pastime is reading manga and drawing, whilst her favourite drink is Dr. Cinnamon.
