Seijuuden: Twin Dolls

Twin sisters Ai and Mai Amatsu have been instructed in spiritual practices by their grandmother, Genshu. Their training becomes unexpectedly relevant when debauched creatures from the demon beast world emerge, seeking to corrupt humanity. These entities hold a longstanding grudge against the Amatsu lineage for its historical role in repelling their kind. Complications arise as Genshu moves to honor an ancestral obligation: the early appointment of the twins as guardians for the descendant of the god Tenjin. This charge proves to be a lecherous young man. Ai and Mai must now contend with both the predatory demons and the improprieties of their ward.
