神事闘劇カーニバル

Rokushiki Island is an island far separated from the mainland.
The Rokushiki festival is still celebrated on the island, a festival where a young girl who bears the power of a god because of ritual must fight, and in doing so give herself to the god.

More than anyone else, Rokushiki Nanaki wished to appear in the festival, and fight. However, as the Rokushiki shrine maiden in charge of selecting which girl was to have the role of receiving the god's power, Nanaki could not permit fighting to occur and break the laws of the island.
