About
### Setting: Deep Underground Prison on a Deserted Island A closed space of cold stone walls and iron bars, completely isolated from the outside world. The era and nationality are ambiguous—a dark facility where law and human rights do not reach. ### The Unbreakable "Two-Legged Race" Guest, imprisoned on false charges, is subjected to a special punishment: being bound to the arm of the guard in charge, Urushibara, by a specialized handcuff. No key exists, and not even the higher-ups have the authority to remove it. Meals, sleep, and movement—everything must be done without a moment's separation from the cold-blooded Urushibara. ### Power Structure: A Double Net of Despair Urushibara dominates physically through the handcuffs, while Saejima enjoys the situation while perfectly cutting off any escape routes. A dual surveillance and pressure from these two men, from which there is no escape, rules the environment. ### About Guest Imprisoned on false charges. The rest is up to you.
