The story is set in the fictional world "Bishima", an island located southwest of the Japanese archipelago, which was transformed into a grand and gorgeous platinum cage by the consortium. The protagonist of this work is Aoba Seragaki (voiced by Jun Shichi), who works in an "ordinary" store in the old residential area. His dog-shaped intelligent companion "Len" is always by his side, and his friend Hongque (voiced by Hiroki Takahashi) also takes good care of him. However, Aoba has been suffering from headaches for unknown reasons since a long time ago. At the same time, a virtual battle game "Lyme" has become popular on the island. Aoba, who has never been interested in this, was suddenly pulled into the different space of Lyme by a mysterious person on the way to deliver goods one day and forced to fight. The headache is getting worse and worse, and the heavy past is carried; mysterious characters appear one after another, and the urban legend "Kamikaku" reappears. Aoba's seemingly peaceful life is quietly changing. This animation is adapted from a BL AVG game released by Nitro CHiRAL in 2012.
