Why oh why would he do that?

Amazing! Keep up the good work!

Love the story so far but would love to see more character interactions like his meeting with guildhearts

Since the mc is pretty OP already, I would say hold off on rapidly shooting up his strength and focus more on the interactions with the characters or something like making preparations for canon instead.

Damm thats a good one! hope to read more of it soon

Well.. to me nothing wrong with op mc.. as long the author can make it to the plot.

I wish there were more fics like this. It’s a great story, but the only problem is that you made the mc too strong too early. However, it does make sense with the story line.

The chapter was awesome, cant wait for the next one!

No magic in Fairy Tail? I'm out

Awesome so far keep it up

He's way too powerful. If you're gonna make a OP MC story, then your story should not focus on action. Because right now, there's just no point in reading this fic except for seeing in which order he's going to destroy his enemies and which girls he's going to fuck. That's actually all there is to it. If you wanna learn how to make a OP MC story work, go analyze One Punch Man and you'll see that fighting isn't something that Saitama does often and even when he fights, it's usually done in a comedic way. The readers already know he can one punch everything out of existence so if there's nothing else to his fights, nobody would give enough shit to continue reading it, let alone like it.

The same goes for your story. Right now, your MC is just so powerful(and he's still 9, he'll be like 22 when cannon starts) that we all know he's never gonna lose a fight or get seriously injured. At worst, he can just activate speed force and run away to the other side of the planet... On top of that, you are still making him learn practically every magic out there and he's better at all those magic than their main practioners. What's the point of any other character existing anymore? Just to show how cool the MC is? That's not how its supposed to be.
Anyway, I'll continue following this to see where you take it, but my advice is, get rid of either the speed force or any other ability that he may learn if you want this story to be anything better than a classic 12 year old's wish fulfilment fanfic.
Just my advice

Nice

Good so far i am enjoying it.

As I keep reading the chapter, one word, keep repeating in my mind: why?;
Why is lie about the name of his world?, why lie about being royalty?, why lie about the roman empire conquering the world?, why make a another identity? and just keep going on, just the latter get me baffled, he is just hunting demons, so why make a new one?
I pretty sure that you can explain the abillities that doesn't have magic, without those exaggerations, the more complicated the lie the more dificult is to maintain her

loved it can't wait for more
