Yōkai senki (妖怪戦記)

Kyuubi resides at the Fox shrine. She cannot eat offered aburaage for
some reason, so she refills her magic energy by intake of sperm instead.
In preparation for the annual Yokai Festival, she goes to the Tengu forest
in search of Tengu who hasn’t shown her face for a while.

While looking for Tengu, she comes to know that many Yokai are missing
all over the country and a group of foreign Yukai is invading the country.

Thus, Kyuubi and her fellows take action to get to the bottom of it!
