Ah, Another boxing manga? My exactly first thought when I saw the manga cover. Rikudou is published in my country as physical copies and was on sale at the time (23 Volumes for like 45$), to be honest I didn't have a clue this was going to be such a great one. The story is not what I expected, it focuses on a heavier and darker theme about the world of boxing, Riku overcoming his trauma and fear, finding a purpose to fight and finally accepting life. Rikudou is not just an another boxing manga, I feel like every fight that Riku fought has a purposebehind them. Riku slowly learning new things fights after fights and slowly maturing is very well-paced and written.

Overall the manga is awesome and you should give it a try.
