The story is fine and all, but the writing quality is not the best.
In almost every chapter you have dialogs like this:
-"How about all of you first announce your name?" Melody said telling them to reveal their names to her.
"Alright. "
Vincent, John, Iris, Varth, Leilani, and Nevis revealed their names to the fairy, taking several seconds to do so. -
You often have a lengthy exposition to a topic, then somebody mentions it in almost the same words and then you get a reply often in the same style. So you read the same words 3 times in a row. The example above is just one without spoilers, but once you notice this pattern, it gets exhausting to read.
Also, dialogues are far too "detailed". Where a normal, short answer would be the norm and perfectly fine, here you have long answers with all the details so the conversations dont "feel" like conversations normal people would have.
