The moon and the earth are linked by a single contact point, "Mitsuru ga Sakichau Ouren Rakuniushi" where Tatsuya lives under the supervision of the Sphere Kingdom (Moon Kingdom)'s Princess Feena Fam Earthlight who is coming to stay at his home.

Ushio thinks his father's tale of an ancient ancestor impaling a demon on a temple altar stone with the legendary Beast Spear is nuts, but when he finds the monster in his own basement, Ushio has to take another look at the family legend! Fortunately, Ushio knows it's best to let sleeping dogs lie and leave captured demons where they are. Unfortunately, the release of the monster's evil energies begins to beckon other demons to Ushio's hometown! To save his friends and family from the invading spirits, Ushio is forced to release Tora from his captivity. But will the cure prove to be worse than the curse? Will Ushio end his life a Tora-snack? Or will the Beast Spear keep Tora in line long enough to save the city? (Source: AniDB)

Considered as the third installment in the highly popular When They Cry series by 07th Expansion, Umineko no Naku Koro ni takes place on the island of Rokkenjima, owned by the immensely wealthy Ushiromiya family. As customary per year, the entire family is gathering on the island for a conference that discusses the current financial situations of each respective person. Because of the family head's poor health, this year involves the topic of the head of the family's inheritance and how it will be distributed. However, the family is unaware that the distribution of his wealth is the least of Ushiromiya Kinzou's (family head) concerns for this year's family conference. After being told that his end was approaching by his longtime friend and physician, Kinzou is desperate to meet his life's true love one last time: the Golden Witch, Beatrice.

Soon after, a violent typhoon traps the family on the island and a string of mysterious murders commence, forcing the eighteen people on the island to fight for their lives in a deadly struggle between fantasy and reality.
