So, I figure the bittersweet sending to this game would have Nero and V helping Dante seal off the underworld. But with Dante now being the king of the demon realm, he lost everything. Lady cut down and dying in his arms, Trish being obliterated in a overdose of demon power as she pushes Dante away from danger, and Vergil sacrificing himself and taking a blow meant for Dante. His dying breaths apologizing to Dante for being a bad brother and causing issues, and telling Dante to give his sword to his son before crumbling to demon ashes with a final brotherly hug.
The world was saved, but Dante's world was lost.
