It has potential. The oneshot was not that good from the serialized chapter 1.
Chapter 1 is 100 times better than the oneshot. I like the character design for the mc and the girl as well.
I hope they can expand the world development on coming chapters. So far all 4 chapters are great but it need to start building up a world development arc or something.
This manga already got more than 100k views on the official English shonenjump website from 4 chapters. That's an amazing achievement for a new manga.
