Tsukuyomi: Moon Phase Series by Keitaro Arima, Andria Cheng

Cameraman Morioka Kouhei is researching Castle Shebartsvere. Inside, he meets a mysterious little girl, Hazuki, who's been trapped there for two years. Utilising her controlling charm, Hazuki makes Kouhei set her free.

After two weeks of doing chores in Kouheis grandfathers' antique shop, Hazuki asks him for a taste of blood. Not taking rejection lightly, Hazuki furiously prowls the streets for a victim to suck on. Her blood thirst leads to a chain reaction of ill-fated events. Can Hazuki live without using her magic on others?

When the devious Count Kinkle lures Hazuki away, Kouhei and his grandfather do everything in their power to search for her. A trail of clues leads them to a hotel, where they are confronted by a fierce monster! But suddenly, Elfriede appears and helps them defeat the beast. The two men are thankful...and puzzled--why would she help an "enemy"?

The Earl of Kinkel makes Kouhei and Hazuki an offer they can't refuse. He kidnaps Kouhei's grandfather, which forces them to the mansion where Hazuki used to live with his mother. But when they arrive, Hazuki starts to recall some memories from the mansion - and learns more about their mysterious ability.

Hazuki is not feeling like her old self. Literally, she has become this very elegant, well-mannered girl named Luna. Kouhei is still her slave - he really wants to be her love slave. Luna has mystic powers during the full moon. Could this be the reason she was locked in the castle?

Kouhei's photographing spirit brings Hazuki into the limelight, but the attention isn't all good. When world-renowned photographer Beat Graham takes an interest in Hazuki, Kouhei realises he's going to need to get a lot stronger if he plans on protecting her. It looks like a far-off relative in the mountains may be his only solution.

Mario is going after Luna (Hazuki) with murder on his mind. Both Kouhei and Hazuki train in order to better defend themselves with the help of Kouhei's twin cousins. Once Mario discovers where Hazuki's hiding, will Kouhei be able to protect her?

A tale of cute cat girls, vampires and psychic mediums. After Balgus, Jeda and Art capture Hikaru, Yayoi decides to unseal Kouhei's ability. Kouhei undergoes training to be able to control his ability since it is so powerful. Hazuki, in fear of unleashing his power, decides to leave. But who will rescue Hikaru?

Just as things might settle down at their secret hide-out, Kouhei and the gang must once again relocate to an island to keep Hazuki safe. Only one problem - vampires and water don't exactly mix. To make matters worse, the special connection that continues to grow between Hazuki and Kouhei is being threatened - by someone in their midst!

Kouhei and Hazuki continue to lie low on the mysterious island and learn more about how their fates seem to be entwined. Kouhei vows to protect Hazuki, and Hazuki comes to terms with the possibility of never seeing her mother again. And who is the enemy who has been lurking in disguise amongst them?

Kouhei's master, Yayoi, orders him to participate in a festival on an unnamed island where there are old, sacred ruins. They feel relieved to be on the inaccessible island, but the female vampire Freya has already landed, and made Kaoru her servant.

Despite Kouhei Midou's entire family being famous exorcists and mediums, Kouhei has zero spiritual powers. But that hasn't stopped him from getting in supernatural trouble time and time again... and this time is no exception.
