Hidden Legend of the Youkai! Tamae the Kunoichi

[Story]
The youkai have escaped after hundreds of years sealed away!
Not only that, but they've captured the princess for the ritual to summon the greatest of all, Nurarihyon!

It seems the ritual involves collecting sexual energy from humans, and injecting it into her body.
Can you rescue her before the energy builds and Nurarihyon walks again?

Take control of Tamae, the princess' clumsy best friend and a ninja descended from the masters
of her clan's secrets -- it's her sworn duty to utilize the scrolls and learn the hidden techniques of
her ancestors from perverted ninja master Raizou so she can bring the princess back home safely.
