Did you not see the Harem tag? we get both and more

Honestly author, I hate that you changed the teams. You just made more work for yourself, because now you have changed so many dynamics like team names, leaders, team interactions and more. Also they're not even the main focus of the story so why?

I'm confused? chapter 1 said his power level was in the 700's now 80 is near his level? did you mean for it to be in the 70's in chapter 1?

Well as long as the love interest isn't an OC im fine with any girl. Nothing is worse than an OC love interest when there are so many female characters to pick from.

and that soul piece became navi didn't it?

he better get a free affinity when tests his chakra affinities, because everyone has atleast 1 and he PAID for this extra 1

seems a bit unfair. why does she get to use ice bending when he's not allowed lightning bending until the 4th round?

honestly I can see the MC being stronger than Jin-woo at the start but by the time Jin-woo inherits the full shadow monarchs powers I don't see how the MC can be stronger with the abilities he has and was granted. The Demon slayer abilities he has are strong in the demon slayer world but when crossed over to other worlds they can be lacking in comparison to other powers. Jin-woo powerful himself and can summon literally undying armies with all kinds of abilities, skills, weapons, and sizes. Jin-woo even ends up resetting the timeline by fighting and defeating the Big Bad's so the dungeons never appeared. when that happens what even happens to our MC?

good luck with your novel but Its not for me. I don't like the devil fruit power and the chapters are too short for my liking. I skipped ahead and they were still short.

when? so far the the mc was building hoping, then this random guy jumps up while he's in the air mid jump and stabs him with a knife. this "robber" has yet to even speak a word to the mc

You did the exact opposite and left the impression that your an idiot. You let a bunch of criminals you could have easily arrested get away. Author I don't understand how you can think arresting criminals WHO WERE ATTACKING PEOPLE would leave a bad impression.

so is the MC going to be ignorant of every world he goes too?

Then what's the point of this story? if the characters cant use they're abilities in other worlds due to the energy not matching up with the worlds they enter then this story is going to get boring FAST. By your logic the MC after going to a world and obtaining Ki wont be able to use it in his original world because there is no Ki in his world and same with any world he visits that doesn't have Ki.

Honestly this is just stupid. The MC is at most Peak human after cleansing his body but most likely not since hes saying he should have exercised more. He's not immune to the zombie virus and all he has his 10 years experience of marital arts but for those to be useful he needs ki or w/e so its just basically normal marital arts. Zombies don't exactly feel pain and Marital arts are used to disable/kill opponents through injury's which the zombies why care about. So his survival odds are basically the same as every other marital artist in japan lol and most of them ended up dead.

So how did he put the bus in his inventory when they were in the bank and umbrella was outside? I'm sure he was way more the 5m-15ft away. Also he knew the zombie apocalypse was going to happen. Why hasn't he stocked up on survival supplies in his inventory in all the years before it kicked off? Even just a little bit here and there would have added up over the years especially with his neglectful father giving him free reign to do whatever.

honestly I think the goliath fight needs to somehow be retconned because it really screws the power scaling of the MC. A basic normal average Goliath is a lvl 4 monster and you had the MC fight a variant making it lvl 4+. also the MC wasn't even technically lvl 1 at the time since he didn't have any falna. so anything lvl 2 and below should be a cake walk for the MC.

sigh, well good luck with your story. not a fan of reincarnation fic's where the mc doesn't know anything of the setting. I mean why not just do an original character at that point, its not like this MC brings anything with him by being reincarnated since he was just at young 18 year old who's life seemed to revolve around soccer (football) from some questionable country. So he shouldn't have any useful knowledge to help in his new life, which means he's just a slightly more mature and slightly more knowledgeable nobody MC. so whats the point of the reincarnation?

so I'm confused, is this story supposed to be a AU code geass? because the last few chapters don't make sense at all since america literally doesn't exist in code geass. The American revolution failed and the British got kicked out of Europe and moved to where America was and thus came Britannia. also most of that happens in the 1800's. there's tons of lore/backstory in code geass. like cannon code geass actually take place in the 1960's

is that it? a multi-billion company that causes the death of 2 ppl and orphans a child is offering a out of court settlement of only 200k? author are you high?! that's not even enough money to raise a child to adulthood in the U.S.A. he should be getting atleast 20-100+million. Remember this is a multi-billion dollar company, the amount of negative news coverage this story would cause would cost them more money and if they fought him in court the public would crucify Oscorp.

whats the point of having juubei levels of chakra and shadow clones and not mastering all his chakra affinities and all ninjutsu knowledge he wished for? you say he wanted to enjoy his life but with shadow clones he could easily do both and more.
