Review Detail of BigiNove in Martial Arts Battle Arena

I design to write a small review after finish the first book. This is a real sport story about a fictional sport called 'battle arena' It could be compare to manga called 'Major' which is about baseball but we follow the MC from his last year of high-school instead of elementary school with the MC has some knowledge and tricks from his first timeline which make it a bit more interesting. The development of story is smooth. I like the MC because he has a very balance personality. The only downside is this so call sport's rule feel a bit weird to me but that is not much of a problem anyway since it is a fictional sport and I focus more on story Lastly, I would like to shamelessly declare this story as the best sport story on this site. (at least IMO)
