Zongman: This World Is a Bit Dangerous!

I have traveled through time, but it has been 3 years since I arrived here before Saki Uesugi really started to get in touch with this world. He originally thought it was an ordinary world, but when he went to the supermarket and saw Saitama with dead fish eyes, he met Saitama when he went to school. When the tsundere Kuronaga Naoto Tosaka Rin, who participated in the Cup War, was sleeping at home and was suddenly informed that the Armored Titan Reiner was attacking the city... He found that he was wrong. This world is not an ordinary violent one. To this, Uesugisaki just wants to say, do it more and harder, the fun has just begun. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
