Lu Ming awakens the "Chuunibyou Godhood System." By performing over-the-top, cringey acts to show off and collecting emotional points, he can continuously grow stronger. During military training on a rainy day, his classmates laugh at him for wildly swinging a wooden stick like a sword, while the campus beauty thinks he's mentally ill. Unexpectedly, the monstrous beast Rain-Howling King attacks the campus. The supernatural squad is utterly defeated, and the entire school faces certain doom! Yet, in the depths of despair, Lu Ming calmly draws his "sword" and declares, "This time, I'll be incredibly cool." In the next instant, one sword strike splits the sky and instantly slays the giant monster. Ten thousand swords bow in submission, and the entire school drops to its knees in terror! You say I have chuunibyou syndrome? Sorry, I am the Sovereign Sword Lord!
