An intruder attempts to steal from a tavern, triggering its lethal defense. The man is confronted by a powerful specter, which his companions identify as a Super SSS-level monster. The group attacks with Thunderstorm Lance and Ice Spike, but their powers prove useless. The specter expands its domain, the 'Execution Ground of Corpses,' ensnaring everyone with unbreakable chains and suppressing their abilities. As one woman is told to flee, the group is completely overpowered and rendered helpless, leaving them trapped at the mercy of the tavern's mysterious boss.
