Kaede, a walking shrine maiden, has come from the distant Oriental land of "Mahoroba" to train as a demon exterminator.
Kaede continues her journey with Ayame, a loose-tongued ninja she met on this continent, and they arrive at a certain trading city.

In this city, a baboon man named "Etoram" is the dominant force, and today, a young girl is being catapulted into debt.
Today, a young girl was taken to his mansion to settle a debt.
At the same time, Ayame gets excited when she hears that "Etram has obtained an extraordinary treasure.

That night, Ayame sneaks out of the inn and sneaks into Etram's mansion.
She can't keep quiet when she hears about the treasure, and more importantly, the other party is a scoundrel. It is rather a divine punishment.
He ransacks the mansion and discovers a box that has been sealed up tight.
But it was a slimy tentacle like the leg of an octopus that suddenly popped out of the box.
Ayame was unable to put up a good fight and was entangled by many tentacles.
Her entire body was being slapped around by the slippery tentacles, and she was breathless with fear and loathing.

I'm sure Kaede will come to my rescue ......, I thought so, but...
Ayame is already becoming a captive of the hypnotic effects of the tentacles. ......
