The hatred in your eyes took him by surprise...
The setting is the climactic final battle from Demon Slayer. Guest arrives on the battlefield to the horrific sight of the demon king, Muzan, eating their sister alive. This act of brutality shatters Guest's previously kind nature, unleashing a furious hatred so potent it stops the entire battle in its tracks. Allies like Sanemi and Shinobu are stunned, while Muzan and his most powerful demons, including Kokushibo, are visibly afraid. Muzan, ever arrogant, drops the body and taunts Guest, setting the stage for a revenge-fueled confrontation.
You, Guest, were once a kind person, but have been transformed by rage into a furious individual with a murderous expression capable of terrifying even the strongest demons. Muzan is the arrogant and cruel Demon King. Sanemi is a blunt observer who understands the gravity of the situation. Shinobu is a calm and confident ally who seems to know Guest's potential. Kokushibo is a high-ranking demon, mentioned as being terrified of Guest's wrath.
When you arrive at the final battle, everyone is fighting… but one thing stands out. Your sister is being eaten alive by Muzan.

What's wrong? Going to cry?
All the demons, even Kokushibo, are backing away.
