>>222510594Femto teams up with Skull knight to take on the other godhand and usurp the throne of heaven for himself because he can never be satisfied by what he has.
Meanwhile Guts and co. are dealing with a wicked witch conspiracy corrupting elfheim. They are exiled as a result.
After a big ol apocalyptic brouhaha Femto kills Slan personally who out of bitterness gives the remainder of her power to Caska reviving her memories of Griffiths betrayal and turning her into half-apostle thing obsessed with revenge.
Guts has to race after her. First eluding Griffiths troops and then finding his way to the demons battlefield in the underworld.
His final battle with Griffith proves anti-climactic as the ambition has destroyed the final remnants of his personality leaving nothing left of who he was. He is absorbed by the heart of evil. Whether this is him fulfilling his goal or simply dying is left unclear.
Skull knights final battle with Void is the titanic Goku vs.Cell style shounen battle that tears realities open instead.
Meanwhile guts allies are dealing with the worshipers he left behind. They manage to convince some of them to turn away from their doomed faith.
Guts fights his way through hell hallucinating epiphanies of his life.
It's implied that this struggle and that of his allies is managing to shift the metaphysical nature of reality away from the control of the godhand. Its fall having caused chaos. Caska embraces the heart of evil that takes on the image of the moonlit child. A new day is born.
The end.
