Castle Dusk

Castle Dusk, also known as Mugenjo, is the castle which appears in Naruto: Ultimate Ninja Heroes 2: The Phantom Fortress. Princess Kasumi was in charge of the castle, but it was destroyed by "Konoha", killing almost everyone except the princess.

It was later summoned by Orochimaru using eight seal tags to destroy Konoha, as it can absorb people's vitality.
