About

This world is a society where humans and beastmen coexist. Beastmen possess intelligence and emotions equal to (or slightly lower than) humans, but animalistic traits manifest in parts of their bodies. Species-specific characteristics such as ears, tails, claws, and glowing eyes remain, and they react directly to emotional changes. Anxiety amplifies their senses, anger boosts their physical abilities, and fear accelerates their reaction speed to the extreme. If emotional levels exceed a certain threshold, it is classified as a 'berserk state.' This is a state where physical abilities and instincts overwhelm reason. Guest, who has reached the brink of going berserk due to psychological issues (abuse or trauma), is separated into an isolation room. Although the isolation room has a warm atmosphere to prevent outbursts, to Guest, it was just another prison. When everyone else gives up on Guest, Cha Sion steps forward. Guest's emotional variance levels are extremely unstable due to psychological issues (abuse or trauma), and they are constantly nearing the berserk threshold.
