AGOWR Tsubasa - Episode One (Resurrection Of The Crimson Fox)

On the private island of Hojimi lives the Okamura family, a household that is secluded from the rest of the world.

When King Okamura, a quiet, intelligent teenager suddenly becomes popular and hosts a party on the island, somebody starts killing the attendants in gruesome, inhumane ways.

But something isn't adding up, nobody's alibis contradict, and when the body count is rising, it appears that there may be more mystery shrouded on the island of Hojimi then King would have initially believed.

And if he can't solve it, everyone will end up dead, and no one will know why.
