I’m the Demon Lord, and I Specialize in Treating the Mentally Ill

On the first day after transmigrating into the role of the Demon Realm’s supreme ruler, I discovered that the entire demonic territory was a psychiatric hospital. The Left Guardian used a spiked club to clean his ears every day, while the Right Guardian was convinced he was a mushroom. The demon generals had spent three years arguing over who should be a chair leg, and the Holy Maiden hugged a broom and called it her daughter. All I wanted was to retire and enjoy a quiet life, but I was forced to become the Demon Realm’s chief psychologist. Then one day, the alliance leader of the immortal sects led an army to our borders. “Demon! Today is the day you die!” I silently handed him a Mental Health Questionnaire. “How about starting with a depression self-assessment?”
