My Skills Can't Be so Hellish

After traveling through time, Zhang Chen thought he would live an ordinary life, but he woke up from the system on the way home from school one day: "Congratulations to the host for acquiring the skill: Bell Twist." "... System, is this bell the kind of bell I think of?" "Yes, you can also call it..." "Okay, okay, no need to say more." This world has magical girls, super sentais, families that dominate the city, and randomly born man-eating monsters. As Zhang Chen continued to advance, the skills given to him by the system became more and more underworld. But what Zhang Chen didn't know was that the underworld skills from his perspective were a great terror in the eyes of others.
