A young boy from a noble family who has been shunned for having 'un - noble' magic like earth - based magic instead of the more 'elegant' magic expected in his family.

The Fairy Tail members accept him wholeheartedly, and he becomes a new addition to the guild.
Well, the new member could be a powerful mage from a far - off land. Maybe they have a unique magic ability like controlling time.

They could learn from each other's fighting styles and grow together in the new story setting.
Well, he could be a really jovial new male member. He might have a magic related to music, using melodies to heal or attack.

He could also be a bit clumsy at times which adds to his charm.
The story could start with Natsu being tricked by a powerful enemy and sent to a far - off and unknown land.

He might meet new allies who help him in his journey back to Fairy Tail, all while learning important lessons about friendship and the true strength of his guild.
Lucy is also a possibility. She is intelligent and has a big heart. She could understand Future Rogue's situation and offer her support, whether it's through her celestial spirit magic or just her moral support.
