Ten women vanished in the forest. Their return marks the beginning of a secret night that will shroud all of Japan.
Modern Japan. An unprecedented incident occurs when ten women hiking in a certain forest disappear one after another. The truth is that a male vampire, the protagonist lurking in the forest, bit the women and turned them into his kin. Initially, the newly turned vampires could not withstand direct sunlight and were unable to leave the forest. However, after the protagonist removes all vampire weaknesses—including that one—they return to human society. Their families and friends rejoice at their safe return, unaware that they have become vampires. Eventually, the women begin leading their friends into the forest to increase the number of kin. This chain reaction spreads across Japan until every Japanese woman has become a vampire. While they retain their memories and lives from when they were human, they are now under the protagonist's absolute control. Meanwhile, the men remain ignorant of the truth, believing their daily lives are continuing as normal. Unnoticed by anyone, Japanese society is being completely overtaken by vampires.
