Thanks for the chapter

This has potential hope you haven't abandoned this

Interesting. After the first time, you misname his Quirk as All for One instead of One for All.

Favorited!

hmmmm cool

Devils, they have a superior body I would think that Izuku is 3-4 times stronger not only that 5% would be higher than normal after all base body strength plays a role too.

It looks pretty good. But Deku quirk is One For All, but other than that it's really good. Keep up the good work dude.

I don't think Deku should have a harem

In panic, he channeled All For One into his legs, ready to grab Yaoyorozu but was halted as he saw a shadow engulf them.

Pretty sure you meant One For All.

Not a bad start though!

Well, I know I'd like to see at least Ochako and Tsuyu in the "harem", if you can really call a foursome that, but I wouldn't mind Toru-chan. Her personality is adorable. A certain character that came in later in the manga will always be little sister to me, so she'd be out. If you don't know who I'm talking about, you obviously have only watched the anime. But given that you referenced the End of Terms, you've probably read the manga. Little cinnamon roll needs to be protected.

Anyways, back to what I was saying, I like the idea of Mandalay being in as well, if only because I read a really cute doujinshi... Don't judge, please... That starred her and Izuku as the main characters.

Now, onto my actual review. There were a few points where I got really confused. Like you put "her" instead of "his", and when you put "said girl spoke" when you were talking about Izuku freaking out, I had to scroll back up a bit to figure out who "she" was. Word of advice, "said [person]" is only supposed to be used when you don't have a Noun in the paragraph before it's use. Usually it's in the paragraph that is talking solely about said person, place, or thing. See what I did?

Anyways, this was a decent start. Good luck with the next chapter, and be sure to have fun with it, so that Writer's Block doesn't set in. If you think something is a chore, then your subconscious puts out a "halt productions" order to your conscious brain. So have fun, yeah?

It seems okay, and yeah a little OOC. I'll keep my eye open for this, but yes go for the harem route as it is DxD.

Was about to say that this had potential since the story telling itself was pretty good but then I saw the publish and update date.

I think deku's quirk is One for All

Interesting ,I look forward to more .By class A harem does that include the guys(i.e Shouto,Katsuki,Kirishima etc) if so please go that route(no offense of course)

Wonder how Rias' group knows All Might's secret let alone how to find One For All's new host. Kind of wondering how this works like is the Highachool DxD world the same world as My Hero Academia's? If so how does Quirks fit into this hybrid world? Can devils, angels, and fallen angels develop quirks or is it just a special trait humans have? Are Deku and Momo still in their own world?
This first chapter raises a lot of questions and piques my interest.
Can't wait to see the next chapter to find out more!
Keep up the great work!
See Ya! :)

I love this idea. I haven't seen this paring yet. and while it isnt my favorite. Its wonderful. I hope you do update this story as I would really like to see how it goes from here.
Thanks for the chapter and have a great day!
