In this episode, Percy's adventures in the Land of the Rising Sun continue, as he re-encounters the beautiful and dangerous Aiko from the train and, even after nearly losing his life for accidentally seeing her... naked, still succeeds in charming her into giving him free lessons at the local dojo. He also takes a trip to the local temple, where the shrine maiden supplies him with some useful information on the mysterious "Grimoire of Magnus", and accompanies Carla on a journey up into the mountains for a cleansing ritual in a ceremonial hot spring... which somehow ends up turning into the holiest ritual of them all - having hot, passionate sex with your mother and filling her still fertile womb with a huge load of your equally fertile semen...
