The captive god-head is flung as a living weapon to duel the demon Slit — revealing her harem enemies, her jealous mother-god, and the worse sister Gash to come.
Psamathe — the split deity trapped as the cackling 'Samantha' doll head, now the party's hired trainer — gets her first taste of combat. When the harem demon Slit comes hunting her, Samantha eagerly demands to fight, and Carl uses the NFC's head-throwing xistera extension (which greatly boosts the range of thrown withering-spirit heads) to hurl her 50 km, taunting Slit into a chase. Her backstory spills out: her father cast her into the Nothing for having a baby with her 'king'; the demon harem (Slit, and the worse Gash) hate her because she boasted of sleeping with their shared king; and the multi-armed god who rips Slit apart is Samantha's own jealous mother, who'd sworn to kill Samantha but killed Slit instead.
She returns to Carl's feet screaming that the kill was stolen from her, a magnet for vengeful gods and demons wherever she goes.
A cackling, white-haired decapitated latex doll head with garish makeup, flung and magically returned; a disembodied minor-deity's true half.
The captive god-head weaponized against a demon, trailing a war of vengeful relatives.
