Devil May Cry 3: Dante's Awakening
After the fight with Arkham, Dante and Vergil have a third and final fight to take the Force Edge and both halves of the amulet. Before Dante wins the fight, the portal to the demon world begins to close. Vergil warns Dante that if he does not leave immediately, they would both be trapped in the demon world forever. Dante refuses to leave until he defeats or kills Vergil, but Vergil chooses to stay in the demon world since the it was once their father's home. Vergil then refuses Dante's help and falls down a waterfall so that Dante would return to the human world without him.
