When I was in a world of unconventional rules and taboos

[No female lead + eerie + mental illness + comedy + national destiny]
My name is Su Ming, and I am a time traveler.
Currently working at Aoyama Mental Hospital, responsible for an important project involving "being researched".
They keep saying I'm sick, but I know I'm not sick; it's the world that's sick.
After I escaped from the mental hospital, I was chosen by the "Strange Tales of Rules" and became the chosen one of the Dragon Kingdom, representing the Dragon Kingdom in the next Strange Tales game.

[Unrestrained (SSS Rank): You are a born madman. Your chaotic and insane thinking makes you immune to the corruption of the supernatural world, allowing you to act without restraint. When you begin to have an episode, you will temporarily gain the ability to harm supernatural phenomena.]
Su Ming, his clear, dead-fish eyes fixed on the group of trembling, cornered ghosts, brandishing a large cleaver, said:
"I'm not sick!"
