Sugiura, Shiho

Cold-blooded and ferocious demon Blood lives inside a cave and has been trapped in an impenetrable wall of ice for decades. His only goal is to find the Tear Jewel, the purest tear shed by a human at death's door. So far, all of his victims have failed to give Blood what he wants until he meets his newest prey: 18-year-old Ishuca Lake Sierra Vise Ell.

However, Ishuca is unlike any other human Blood has ever met. In the presence of the demon, Ishuca never cowers in fear and even wishes to be eaten by Blood, as he is soon to die due to a heart condition. Although taken aback by Ishuca's kindhearted nature, Blood warms up to the boy and his tragic circumstances.

Sadly, Ishuca's illness rapidly catches up to him and he is soon on his deathbed. Wanting to save him, Blood manages to shed the Tear Jewel, which he uses to revive Ishuca. Unaware of everything that happened, Ishuca asks Blood if he can join the demon on his next adventure. With Blood now also free from his prison, he agrees to allow his partially-human companion to accompany him into the unknown that awaits them.

The only way to return to his true form is to win over the heart of a human.

As if by fate, Lee Nok, a wistful and unfortunate prince pining for his childhood friend, takes pity on the animal and brings it in. While Nok's abundance of yin energy attracts malevolent spirits, Jae-shin must absorb yin to sustain himself. In every respect, Nok is the perfect target for Jae-shin's goals. He begins visiting the prince's chambers at night in his human form, hoping to erase the traces of affection for another from the prince's heart and lure him into eternal love.

The Ghost's Nocturne

귀야곡

Hinohara, Meguru

Upon his return to his rural hometown, writer's-block-stricken author Chiharu Izunome meets Rin, an eccentric young man looking for his wife-to-be, whom he met once long ago. However, little does he know that Rin is actually a draconic water god; and that just like a local legend, Chiharu's grandmother had promised Rin her grandson's hand in marriage in exchange for a wish.

Chiharu, however, has no interest in an arranged marriage with a god—especially not a male one. While Rin forcefully invites himself into Chiharu's home and does his best to become the ideal husband, Chiharu looks for any way he can get rid of the god—even if it means calling an exorcist. As the two continue to live with one another, though, they gradually form a bond far beyond that of the simple promise that brought them together.

Sakura-gari

櫻狩り

Huingwi

Vicious nightmares are much different from the regular ones: they are vivid almost like reality, persistent and recurring over an extended period of time, and most dangerously, they create physical injuries and extreme side effects called "malady." Shamans—individuals blessed with spiritual powers—perform rituals in which they enter the affected person's dreams and eliminate the "nightmare seedling" that is causing the vicious nightmares.

When 24-year-old Han Jungoh lands a job as a shaman's assistant, he ends up in the client's dream despite having no spiritual energy. His boss, the serious yet oddly adorable Shin Ibeom, is not too thrilled about Jungoh's interference with his work. However, Ibeom suddenly develops a malady—his body becomes hot and his head dizzy, unable to resist his physical desires. Too distraught and embarrassed to turn to his family, Ibeom asks Jungoh for help, swearing that his attraction is nothing but a bothersome side effect.

Haruto Soma used to love music. Previously, he would write songs to play on the guitar and sing along to them. Haruto left his hometown to come to Tokyo and pursue a musical career, but his first live street performance was a major discouragement. Since then, he no longer experiences the same joy on the rare occasions he touches his instrument.

Still living in Tokyo, Haruto is struck by a scooter one evening and taken to a hospital due to the alarming amount of blood at the accident site. Luckily, he is discharged a few days later, relatively unscathed; the only remaining ill-effect is a fuzzy feeling in his head. 

When Haruto returns home, he discovers a stranger lounging comfortably on the floor of his living area. His first thought is to wonder who this person is; the stranger, however, questions why Haruto suddenly notices him, because he wasn't able to see ghosts before!
