YOKAI SENKI / 妖怪戦記

Kyuubi lives in the sanctuary of the Fox. For some reason
she can not eat tofu to replenish her magical powers,
so she has to absorb the sperm. In preparation
to the annual Yokaev festival, Kyuubi sends to the forest Tengu,
to find the same youkai, which nirazu did not show his face to anyone.
During his quest, Kyuubi learns that many youkai have disappeared,
and at the same time, foreign evil youkai decided to invade the country.
