1. Yami should be the one to get him if you're going to follow cannon and because it woyld be very interesting to read how Natsu will interact with the Black Bulls. And just like Fairy Tail, the Black Bulls often cause chaos behind them, it would be very fitting for Natsu.
That's the only question that I should answer because I believe that you should take this story into how you would want it.
So excited for the next chapter!

1. Make it so that the captains were unsure of his power, and that with him burning his broom and all, that only Yami would take him.

2. Maybe when Natsu gets extremely emotional, which is gonna be a lot, he has little flashbacks and hears his voices from time to time.

3. That would be a good idea, because Noelle can remind him of Lucy since she also complains a lot and is basically partners with Asta., But since Asta is replaced with Natsu, She would basically be his partner instead. So she would definitely remind him of Lucy.

make him as strong as he usually was. You basically already gave him Fire Dragon King Mode, since he already melted the arena. That and I just want to him to kick some serious butt.

nice

Please update this story

Sigue desarrollado la historia por favor

1. Yes, with his display of power in that fight fugo, yami, jack, and William would definitely want him. Charlotte and nozel I don't know.
2. I say make END a spirit dive like spell so you could use the grimoire for regular spells, and END is on the first page. The END book is Natsu in fairytail, but here you can make it a grimoire that contains all of his spells.
3. No not really, wouldn't bring anything since they are dead, I'll leave it to you.
4. Stronger than beginning asta. I'll say strong enough to fight to to toe with Mars. Beginning Mars.

1: I feel like only a few
The lions because fire
Bulls because plot
Dawn because strength
2: When something bad happens to some one or like a trigger word
3: That may just slow down the plot if your not going for him going back
4: I’d say a bit lower than Julius but close because he was able to kill big bad dragon dude with help

I think in the start E.N.D. should only come out when Natsu is in a lost battel and later in arc 3 maybe later learn how to control it's power. Yeah i think it would be good if Natsu have flashbacks.

i like this story

1. everyone who wants it but please don't enter the black bull too often, put him in a deep red lion

the end of the story he comes out when a strong enemy becomes his opponent

3 no

4. vice captain strength

Nice idea hope you update soon

Love the story

Can you please make a "Black Clover" and "Ozzy & Drix" crossover?

Put him in the crimson lions he could give Leopoldo a run for his money

i think mereoleona and natsu should be just really close friends, almost brother and sister like, with people wondering if she is his mother, since they are so alike and the two of them vehemently denying it, making it a running joke
