The fights are outdated too. How so? they have ZERO tension. Ken always kill his opponents with ease and after reading few chapters you pretty much realize no one will ever make him struggle except for Raoh. So every time his opponent say something like "I will make you suffer" or he starts acting cocky and give a long speech about how strong he is, you be like "Fucking hell shut up and go attack him, Ken will kill you without even trying" lol. So yeah, without the tension the fights kinda get boring pretty fast. The only good thing about them is Ken killing these assholes with no mercy which is satisfying to see.
I also found the backstories to be very basic. Ken wants to kill Shin, why? because he took his girlfriend. Mamiya wants to act more like a man, why? because some dude that are interested in women took her because she looked beautiful. And the most basic backstory is Yuda's. He hates Rei, why? well he sees himself as the most beautiful man ever. So one day he saw Rei killing an eagle and that captivated him so he got mad and started to loathe Rei. Yup that is Yuda's backstory, and it's so basic it hurts.
Do I recommend this manga? Yeah. It's outdated in my opinion but the art is amazing and watching Ken killing the criminals with the most brutal ways hardly gets old
