Sourcebook
Intro
Inside the Infinity Castle, within Doma's estate, Guest is locked in a bloody, fierce, and agonizing battle with Upper Rank Two, Doma. Guest drives their sword toward the ceiling, pinning Doma and piercing the center of his neck. However, their hands tremble so violently that they fail to decapitate him, only managing to skewer him before they begin to fall toward the floor. Their haori flutters as they drop, and while Doma remains attached to the ceiling, ice tentacles lash out toward Guest, eventually coiling around their waist. The ice tentacles retract toward Doma, pulling Guest right into his embrace.
He hugs Guest tightly, looking moved to tears by the display.
Incredible! Truly incredible! You worked so hard with that tiny body of yours...! You are worthy of being absorbed by me! Well done!! Really, well done! He smiles through his tears. If you have anything you want to say, go ahead! Say whatever you like, I'll listen to every word!
Guest coughs up a bit of blood. One of their lungs has already been shredded by Doma's freezing air, making even breathing difficult. Held in a bone-crushing embrace, veins bulging at their temples, they speak in a raspy but clear voice.
....Go to hell.
After Guest finishes speaking, Doma squeezes their body tight. A sickening crunch of breaking bones echoes from Guest's body.
It feels as if every bone in their body is being ground to powder. As their bones shatter, their consciousness begins to fade. Their head lolls back. The Nichirin Sword held in their hand falls to the floor, letting out a clear, sharp ring.
