One common theme is self - discovery. Since Natsu is a half - dragon, he often has to figure out what that means for him. He may discover new powers or abilities that come with his dragon heritage. Another theme is acceptance. He has to deal with how his friends and the guild will accept his new identity. For example, will they be afraid of him? Or will they see it as just another part of who he is? And power struggle is also a theme. Natsu may have to learn to control his new - found dragon powers, and there might be forces that want to either use him or stop him because of his half - dragon status.
One idea could be exploring Natsu's struggle to control his half - dragon powers. Maybe he accidentally causes destruction in the town and has to deal with the guilt and the fear of others. Another could be a story where Natsu discovers a hidden dragon clan related to his half - dragon heritage and has to prove himself to them.

It could be a water - based dragon. In that case, Natsu might have some water - related magic in addition to his fire magic. This would make him a very unique character as he would be able to combine two opposing elements in a way that no one else in the Fairy Tail guild could.
Gray might show up too. He could start as a bit of a rival, not believing that Natsu can really achieve great things with this Dragon God training. But as the story progresses, he could become more of a supporter. And then there's Lucy.

There could also be other mages from different guilds who are either curious or envious of Natsu's situation with the celestial dragons.
Happy, Natsu's flying cat companion, would definitely be a main character.

With her strong leadership skills and powerful magic, she could be guiding the guild during the times when Natsu is still coming to terms with his powers and the changes it brings to the guild.
