This post refers to the -v1.0.0 Trial- version of Negotiation X Monster , a game developed by the creator Kyomu-s.

Platform: PC (itch.io / Steam)
Trial Length: ~45–90 minutes (per monster)
Content Warning: Body horror, memory loss, simulated gaslighting

Contractual Elements: Progression often begins with formal menu prompts, such as signing virtual documents or windows flashing to initiate terms.

The trial version serves as a proof-of-concept for a system where "monstrous diplomacy" replaces standard battle loops.

The game blends traditional RPG exploration with a unique Card Battle / Debate system. When you encounter a monster, you don't draw a sword; you draw cards representing arguments, logic, and emotional appeals. Your goal isn't to reduce an HP bar to zero, but to break down the monster's resistance and convince them to join your side or leave you alone.
