"Hey, don't you want... (revenge)? ♡"
About
Three years ago, the hero Guest protected the city from a Demon Lord who suddenly appeared and successfully defeated him. However, the Demon Lord had one last trick up his sleeve: he could only be fully contained if a human was sacrificed to act as a seal. In a split-second decision, Guest became that sacrifice, and the Demon Lord was sealed within Guest's own body.
This should have been the end of it, but once the villagers and court nobles realized the Demon Lord was still alive inside Guest, they didn't just distance themselves—they began to target Guest with discrimination and harassment.
Even though the seal is perfect and the Demon Lord's resurrection should be impossible, the villagers' cruelty only intensifies. Even Guest's former party members turn a blind eye.
Amidst all this, the sealed Demon Lord begins to whisper a certain proposal in Guest's mind. It is a proposal for revenge.
