Great idea though I’d suggest fleshing the world out more as Izuko can come across as too OP for the current story line (Anime only). Maybe have the League of Villains or whatever they’re call gain more recruits due to Izuko’s fame/infamy.
The Haki thing was a wonderful idea because of how well it can scale and offers versatility. Half the reason I read fanfiction is because I love seeing a diverse use of abilities and how they can change a story. That’ll be interesting to see as things go on depending on how you play things out.
The scene with the children at the beginning came across a bit surreal with the wordings they used but if I remember correctly the story is set in the future so I guess quirks might not be the only thing different for humanity. That and I can’t believe so many people have quirks and most are fine leading ordinary boring lives. Actually if Izuko inspires people that could lead to more heroes and villains and that could solve the OP problem, if that even becomes a problem.
Are you planning to pair Izuko’s mum and all might? Well guess I’ll see in the future.
Some might say that Izuko seems Gary Stu but from my experience people who put effort into their lives and improving themselves always do seem like Mary Sues/Gary Stus. That and Izuko exercises his willpower often (discipline without the army identity brainwashing is very healthy for an individual), and the effects of that type of lifestyle along with continuously having mantra active must have some effects on anyone’s psyche.
I don’t really have much to say about the pairing, single is better for romance and harem is better for exploration of stories and characters without getting bogged down in romance and relationship drama. Actually, just for the fact that there probably won’t be excessive relationship drama in this story I gotta say thank you! I’m so exhausted of that crap.
The chapter was well written too if a bit annoying how closely it tread to cannon. Still having a familiar foundation to a fanfiction is great for actually seeing the differences and what they mean. I can’t really think of anything to add other than Izuko did need something more interesting then buffed up physical stats and I’m glad to see a story like this.

Good. Please Continue...

This is how you make Izuku a badass without overdoing it. 10/10 chapter.

Hell yes to this story.

Holy shit that was impressive I can't wait for the next chapter! When will it come?! When? When? When? When? Please tell me when! If you don't want to I ain't forcing ha

Great story, loving it so far, but I have two things I'd like to say:

1. Replace Momo with Himiko in Izuku's oncoming harem, mostly because I have Momo and Shoto as an OTP.

and 2. Have All Might get with Inko, also because they're my OTP.

Other than that no problems. Keep up the good work!

Huh, adding the Colors of Ambition to Izuku... I have to admit, that's original.

But as far as complete invulnerability to the after-effects of OfA, I have skepticism.

While your Izuku has much more confidence in himself, I'm fairly certain that he may still pique with some canon moments, so as to ensure that he is him, and not an OC with his name.

Also, I do hope you can save the little girl Eri. Personal preference, but still.

my suggestion, if ur gonna make OP...then make it OP, downplaying strength something cause the story to become worse in my opinion. nice story, keep going.

I always thought a Female Todoroki would be great for a Harem fic

Amazing!

this is perfect

i eagerly wait 4 more

Dude, add Toga in his harem. It works for my hero academia because a hero dating a villain makes very interesting. If you want my reasons why, just ask. Also, are you going to add sanji's style of fighting and diable jamble and the rokushiki?

Very interesting story so far looking forward to where you will be taking this. I have a few suggestions for you if you don't mind. Calling the first Haki "armament" but the second "mantra" threw me off big time and kinda felt out of place, as why would Izuku use that word for it when in the world of One Piece only a very specific place uses it and it is know as "observation" everywhere else in that world. I'd say keeping all three consistent as "armament, observation, and king's" would be better.

My other suggestion is to really limit the number of girls in the harem. You have five confirmed, two possible additions, and are open to a total of ten. That is just too much. I've read lots of harem fics over the years and the biggest fault in them is people want everyone in them which means that very few of the girls get characterization beyond being into the MC. If you think you can write all those characters then more power to you, but I recommend you pick three(or four at the absolute most) girls YOU want to write and use that as the harem that way you don't have to figure out how to keep them all in character and equal in the story to each other.

That's so cool how in someway you have him all aspects of the 3 types of haki awesome. I can't wait for more. I'm addicted and I just can't get enough.

I love it ! I just love your ,,Deku" ! Keep going !
