A 12-episode anime television series adaptation was made by J.C. Staff, broadcast in a post-midnight slot on TV Asahi and ABC from April 2005 to June 2005. The anime series was licensed and released in the US by Media Blasters in a set of 3 DVDs in early 2006. A 12-episode anime adaptation was made by J.C.Staff, and first aired in Japan from April 2005 to June 2005. The episodes covered approximately volumes 1–4, due to production starting in August 2004—about four months before volume 5 was published. Because the source material hadn’t finished its serialization, and with a limit of 12 episodes, the anime adaptation has quite a few differences. The most notable is the series finale, which was written specifically for the anime and left the storyline open to the possibility of a future sequel. The opening theme music was “Tsuki no Curse” and the ending theme was “Michiyuki”; both were composed by Yuki Kajiura and arranged by Masayuki Sakamoto, and performed by Kaori Hikita. Media Blasters licensed and released an English subtitled version in early 2006. On April 26, 2011 Media Blasters re-released the series with an English dub titling it as “Loveless: Vocal Collection”. The series is also licensed in German by Tokyopop.
is twelve years old and the protagonist of the story. He was named after the lunar day “Rikka,” which fell on May 5 in the year 2005. His “true name” is Loveless, although it is yet to be seen on his body as the other teams’ names are. He enjoys taking photographs and “making memories.”In the first volume, the story alludes to an abrupt change of personality occurring in Ritsuka two years prior. It is seen often through flashbacks, when his mother beats him and denies that he is truly Ritsuka and that he is actually someone else in his body. Before this change, he was a popular, yet academically average student; he doesn’t get along with his classmates, and he purposely points out their faults. In contrast to this, he is the perfect student now. In addition to the personality change, he suffers a loss in memory. The cause of these drastic changes is still unknown, although he has regular therapy sessions to determine why.On his first day at his new school, Ritsuka meets Soubi Agatsuma. Soubi confuses him with his sudden intimacy and puzzling claims that he was Seimei’s friend and Fighter Unit. As Ritsuka discovers, Seimei’s impromptu will dictates that Soubi shall “become Ritsuka’s” upon his death. Ritsuka and Soubi’s relationship is complex, but in many ways Ritsuka admires Soubi. However, Ritsuka has trouble trusting others, and Soubi’s various secrets continue to have an adverse effect on this. Despite his young age and inexperience, Ritsuka is very intelligent and approaches things with startling maturity. The circumstances of his life encourage his lack of innocence; however, there have been notable incidents that bare his naïveté, particularly in sexual love and healthy relationships. Despite this, he still has firm opinions and unrelenting ideas about those subjects. It is these opinions that clash dramatically with adults and authority figures around him, most notably Soubi. Ritsuka is a pacifist, and strongly opposes violence under any circumstance. Love is an uncomfortable subject for Ritsuka. He is wary of compliments, and doesn’t like affection. Ritsuka’s inner conflict over believing Soubi’s declarations of love becomes a source of great tension and bitterness in their relationship.
is a twenty-year-old student, studying Japanese art. He is a former student of Shichisei Gakuen (“Seven Moons Academy”), a school for fighters, where Ritsu Minami was his teacher. He arrived at the school and became Ritsu’s student after the death of his brother, who was Ritsu’s former partner. Ritsu raised Soubi and, incidentally, was the person that took his ears. Whether it was a consensual act or not wasn’t specified. It is hinted by another teacher at the school that Ritsu took Soubi’s virginity because Soubi had his mother’s face, which made Ritsu desire him. Ritsu explains to Soubi that he took his ears to make him a better fighter. Soubi is later partnered with Seimei. He doesn’t enjoy this, feeling attached to Ritsu and resenting that Seimei is younger than he is. Seimei notices this and mocks Soubi for feeling attached to Ritsu. He later carved the name ‘Beloved’ into Soubi’s neck, making him his fighter unit. As ordered, Soubi contacted Ritsuka after Seimei’s death. He introduced Ritsuka to the world of fighters and sacrifices and told Ritsuka he would be his Fighter Unit. He fought beside Seimei for some time, and many people believe that he is Beloved’s Fighter Unit. The appearance of Nisei in the manga, however, proves this to be false later in the manga. Soubi now fights for Ritsuka as Loveless, which is considered taboo because there is not a fighter-sacrifice bond between them. There is also a severe loss of strength, and in Soubi’s case, his markings bleed in battle. Soubi was revealed to not have a true name at all—in fact, Ritsu comments that he is a blank slate, and whatever marking he is given becomes his name. Since Seimei carved Beloved into his skin, it became his name. When given a command to break the windows, courtesy of Seimei, in volume 8, it is shown that he cannot disobey, no matter how strongly he is against it. Soubi appears to know much more about Seimei and his cause of death than he will divulge. Despite Ritsuka’s insistence that he tell him everything he knows, Soubi refuses. In volume 5 of the manga, he even says, “Seimei is my God.” He openly declares that he lives his life by Seimei’s orders, but still says he’ll obey Ritsuka’s every order, which is not necessarily true. Because Seimei told Soubi not to tell Ritsuka about the seven moons he cannot tell him.
