Hijiri Minase's joy at being able to play the violin again thanks to a donated cornea fades as his precious instrument is destroyed in a fire. Offered a replacement by Kazusa, the daughter of the cornea donor, little does Hijiri realise the secrets that the violin holds or that the true despair is only just beginning.
Hijiri is crushed to learn that by receiving Tatsuya Otonashi's cornea he has been entered into a contract with the devil that will culminate in the death of both Hijiri and his close friend, and Tatsuya's daughter, Kazusa. Determined to defy the pact, Hijiri tries to go on with life as normal but soon discovers this is not an option and that the assistance of Tsuzuki and Hisoka may be his only solution.
Despite what he may believe, Hijiri Minase's contract with the devil is far from over and now Tsuzuki, under the devil's control, is looking to fulfill both parts of the contract. Distraught at his friend and partner's suffering, Hisoka set a plan in motion with the hopes of freeing Tsuzuki from Sagatanas' control, however the risks are great for all involved.
A request from the Count himself leads Tsuzuki and Hisoka to the Queen Camellia cruise ship to investigate its ties with the mysterious longevity of a number of people who were due to die. Once on board, Hisoka finds himself drawn to Princess Tsubaki, the daughter of the ship's owner, while Tsuzuki is horrified to discover an old accquaintance alive and well. As one of the passengers is killed, suspicions turn to all directions but Tsuzki and Hisoka have one particular suspect at the top of their list.
The serial killings take an unexpected turn as Dr Muraki becomes the second victim. Tsuzuki and Gushoshin attempt to unravel the mystery of the Tarot Cards left at each killing, however Muraki's card, the King of Swords ripped in two, leaves them stumped. Hisoka, meanwhile, furthers his friendship with Princess Tsubaki but uncovers some shocking truths in the process.
Dr. Muraki's miraculous return from the dead helps Tsuzuki and Hisoka unravel the mysteries of the Tarot Card murders, however the truths they uncover are not easy to stomach. With Princess Tsubaki under Muraki's control, Hisoka is forced to fight his new found friend in order to save her from her torment, but will the power of the Guardians of Death be enough to save this victim from her fate?
A serial killer taking a lock of hair from each victim leads Hisoka and Tsuzuki to Kyoto, Watari's home town. When a lock of the murderer's hair is found at the scene of the latest victim, the pair discover that their criminal is none other than Dr Muraki and a run in with the evil doctor leaves Tsuzuki battling with memories of his past. However Muraki knows more about Tsuzuki's past than he is letting on, and what Tsuzki doesn't know could just be his downfall.
Descendants of Darkness is a supernatural story with hinted shonen ai themes, akin to some of its more modern and popular counterparts, such as Uraboku. The characters and story are thoroughly interesting, and honestly, my only serious complaint was that it was too short. Dark pasts behind the flamboyant and angsty (and handsome) protagonists, a truly unlikable villain, intriguing plots with unexpected twists, and small shots of comedy are all positive qualities this anime has to offer. Unfortunately, the length given to the stories is far too short, leading to rushed character development that feels a bit unnatural. Also, I watched the dub, and although I quite enjoyed it and thought it humorous, the antagonist's nasally voice was incredibly hard to take seriously. Overall, this is a great anime that I will not forget quickly. It is worth the time of anyone who is a fan of the genre. If you are not into other similar works, this may not be on the very top of your priority list, but surely a fun time for a rainy day.
