For a second there I thought Ignia was an illusion until Irene transformed.
As for Natsuya's second dragon slaying magic I would say it should be Soul Dragon Slayer magic because some people have speculated that Acnologia could you some form of Soul Slaying magic before the big reveal of him being a Magic Dragon.

I am very interested I this development though I haven't read the 100 yes quest manga

A well done chapter. An interesting look at what the Alvarez Empire were doing as Larcade takes a walk outside, but is taken back immediately. It was quite interesting to read Serena and Irene as they will be tasked in training Natsuya in the future. Their thoughts and reaction to doing so shows they aren’t very thrilled about the idea. A good explanation about the Five God Dragons and how they don’t take well to humans. Ignia makes his move and it would seem the Alvarez will be in a bit of ruin. Thank you. Keep up the good work.

great story can't wait to find out what happen next so update soon please...

Fire Devil Slayer Magic since she IS E.N.D as well.

I don't think any but if you do choose one make it something like take-over. Just not Requip its kind of overdone as a secondary magic.

Updatw

A well done chapter. It was amusing to read how Natsuya viewed August thinking he was her grandpa, but in reality he is her nephew. Quite interesting to read about Ignia and how he views Natsuya as it would seem he doesn't like her very much and might want to destroy her when she is at her strongest. To show that he is the strongest of Igneel's children. It was also interesting to know that Acnologia took an interest in Natsuya and seemed to have trained her as well and that her memories are locked of some sort. Going to where the Empire is located, nicely done with the different point of views of two characters, Ajeel and Larcade. It would seem the two are troubled with one not being able to control is powers and the other having a dark past. Can't wait to see how Natsuya will interact with the Spriggans when she makes it to the Empire. Thank you. Keep up the good work.

Looking forward to this story. I hope Natsuya grows into a very lovely and attractive young lady. And get herself a reverse harem this instigating overprotective Oni-chan.

more and fuck ignia

I think this chapter is really interesting, I cant wait for more interactions between August and Natsu, or for more Ignia, even though he seems like a bad guy

I think including Ignia is a neat little addition. I'm right with you on the "not sure about 100 years quest" boat but I think if it used carefully you can take parts of it to enhance your own story. Looking forward to how Natsuya interacts with some of the younger members of the Spriggan 12! I'm sure she will make it something interesting

hope to see more of this the concept is nice and really interests me

It sounds interesting

A well done story. This is quite the interesting turn of events on August as he looks for Zeref’s younger sister to be trained and grow stronger. A well done start as it shows a bit of August’s reasons for looking for Natsuya and telling Larcade. This has piqued my interest and I wonder where this story will go as well as how much will change. Thank you. Keep up the good work.
