Welcome to the Tsukuyomi Moonphase fanclub.
Tsukuyomi -Moon Phase- is a manga series by Keitarō Arima about a young vampire girl named Hazuki and a Japanese freelance photographer Kohei Morioka whom Hazuki attempts to make into her servant.
The manga was adapted into a 25 episode TV anime series by the Shaft studio and aired late night on TV Tokyo from 4 October 2004 to 28 March 2005, followed by an additional 26th episode released only on DVD in 22 February 2006 which featured art from Type-moon.The OVA storyline has very little to do with the original series outside of having some of the same characters, and has a completely different storyline which does not fit into anything which came before it.
TOKYOPOP publishes an English language version of the manga while FUNimation is releasing English language version of the anime under the name Moon Phase.
STORY
The story is about the relationship between freelance photographer Kouhei Morioka and Hazuki, a teenager who descends from a royal vampire lineage. At the beginning of the story, Kouhei travels to a castle in Germany to take some photographs of paranormal phenomena for his friend Hiromi, who is the editor of an occult magazine. At the castle, Kouhei meets Hazuki, who feeds on Kouhei's blood and claims him as her unwilling servant. Although this "blood pact" is supposed to bind Kouhei to Hazuki as her obedient slave, her act has no effect on Kouhei (later in the series, it is revealed that this is because Kouhei is "the vampire's lover"). Following an action packed sorcerers battle, in which Kouhei and his cousin manage to free Hazuki from her captivity in the dreary castle, Hazuki travels to Tokyo, and takes up residence with Kouhei in his grandfather's house in Japan. Hazuki claims that, because she fed on his blood, Kouhei is now her servant, but Kouhei continually refuses to obey her, especially when he thinks her requests are unreasonable. Despite their fighting, the relationship between the duo progresses over time - even in the face of repeated attacks by opposing vampires - until Kouhei becomes determined to protect Hazuki from the vampire servants of her family, who are determined to retrieve her by whatever means necessary.
CHARACTERS
Hazuki/Luna
Voiced by: Chiwa Saito (Japanese), Monica Rial (English)
A selfish but adorable vampire, whose age is narrated as somewhere between prepubescence and early teens, Hazuki was separated from her mother and restrained in a castle in Germany. She escapes the castle with Kouhei's help and flees to Japan in search of her mother. A vampire's kiss, the act of drawing blood from a mortal, normally turns the mortal into the feeding vampire's unwilling servant, but Hazuki's attempt on Kouhei fails. According to the story line, Kouhei is narrated as "the vampire's lover," and therefore is immune to the binding power of Hazuki's vampiric "kiss." Despite her continuous claims that Kouhei is her slave and must obey her every command, Kouhei refuses to do so. Her family is desperate to retrieve her because she is actually a "daywalker", a vampire who, unlike others of her kind, can withstand sunlight. She is plagued by an alternate personality named Luna that was forced upon her by her vampire relatives to keep her under control. Her name is pronounced closer to Hahd-ski.
Kouhei Morioka
Voiced by: Hiroshi Kamiya (Japanese), Jason Liebrecht (English)
Kouhei is a photographer who, due to an accident involving paranormal forces in his early childhood, is oblivious to spirits and the supernatural (which he specializes in photographing). He is an "Ama Lamia" (Vampire Lover), meaning no vampire can make him their servant. Furthermore, vampires who feed on him have their servitude ties with their masters broken, making of him a threat to the vampires' society structure. Later it is revealed that he possesses great spiritual powers which were sealed by his family in order to allow him to live a normal life, as they were too strong for him to control. From their first meeting, he and Hazuki have a tempestuous but affectionate relationship that eventually turns into romance. In the manga, Kouhei's surname is Midou.
Ryuuhei Midou
Voiced by: Mugihito (Japanese), Randy Tallman (English)
Ryuuhei is Kouhei's grandfather and a powerful spiritualist and exorcist. Kouhei lives in his household, which is located in an antique shop. He agrees to take Hazuki in out of kindness, though he appears to have other motives for it as well. Later in the tale, Ryuuhei develops a relationship with Elfriede.
Seiji Midou
Voiced by: Takahiro Sakurai (Japanese), Sonny Strait (English)
Kouhei's cousin and a powerful exorcist in his own right. Later in the series it is revealed that despite training his entire life, his powers are no match for Kouhei's latent potential. Because of this, he is slightly jealous of Kouhei. Seiji Midou (御堂 晴爾 Midō Seiji?) is his writer's name.
Haiji
Voiced by: Vanilla Yamazaki (Japanese), Gwendolyn Lau (Episodes 2-5), Luci Christian (Episodes 6+) (English)
Haiji is Hazuki's guardian spirit. Haiji originally belonged to Hazuki's mother Chizuru, but the little spirit guardian lost most of her memories of Hazuki's mother when she was reassigned to Hazuki. Her name was "Heidi" and she had the form of a cat when she belonged to Chizuru.
Count Heinrich von Kinkell
Voiced by: Takashi Matsuyama (Japanese), Troy Baker (English)
One of the minions of Hazuki's family, Count Kinkell tries to kill Kouhei and retrieve Hazuki, but is defeated by them with Elfriede's help. He is able to control and bend light which allows him to create illusions and walk under daylight.
Elfriede
Voiced by: Yumi Kakazu (Japanese), Stephanie Young (English)
Elfriede is Kinkell's daughter and servant. His control over her was nullified when she fed on Kouhei's blood, and since then she joined his and Hazuki's side. She is able to summon creatures and monsters.
Hiromi Anzai
Voiced by: Michiko Neya (Japanese), Laura Bailey (English)
Hiromi is a childhood friend and co-worker of Kouhei's, assigning various photo jobs to him. Has a notable crush on Seiji. She is also a horrible driver. Her relationship with Hazuki is much like a doting older sister.

Artemis ("Arte")
Voiced by: Sawa Ishige (Japanese), Carrie Savage (English)
Hazuki's younger sister, Arte envies her because of the attention their family dedicates to her older sister, and because of it Arte is determined to deprive Hazuki of everything and everyone she truly cares for, taking by force or destroying completely.
