It was finally December 29th and Zoro was excited. He had just remembered that he had wished for a devil fruit and haki! He didn't know what he would unlock first nor did he know what he would tell people about his quirk. He finally realized just how op he could become in this world where a quirk determined his worth. One piece had been his favorite anime and manga, the powers were too good to pass up for a low-key Otaku like him. If he trained right he would be able to laze around for the rest of his life without worry.
Now you may be asking "Well Zoro, even if your the strongest how are you gonna make money if you won't be a hero??" He had immediately chosen to write books and manga from his past life and sell it here for a life of luxury. His third wish had been for this, whatever he chose to do, if he trained for it he could accomplish it.
Since he chose to be a mangaka, he had been training his drawings from small pictures to large paintings. He could feel himself getting better and better at an incredible pace. If he kept up he could make a manga by the time he was 10. As for writhing... he basically copied harry potter and others, such as lord if the rings or percy jackson. Some would be mad that he's copying others but he doesn't give a shit. He could live life how he wanted with the type of money j.k. rowling had in his previous life.
The first thing he would do is set chio up for a nice retirement, and repay all her good will and the tough times he had given her.
Getting back on track, He and Granny chio were at the fields as he had been feeling weird since he woke up this morning. It was if there was an itch inside him waiting to be scratched, he had new instincts that were assessing everything he could see. Finally after pacing in place for 20 minutes, he suddenly felt the urge to move his hand, he also felt a weak energy inside himself. Looking at his hand he pushed it forward as his arm became a dark grey along with purple lines flowing on the sides. Feeling the energy also move incredibly slowly he concentrated for a moment before a royal purple mist moved about 5 inches off of him. Immediately he fell to his knees feeling exhausted and drained.
Granny chio exclaims "Are you okay little Zoro!?" feeling bad for worrying her he tells her that he's just exhausted from expelling so much energy. Feeling relief she responds " That's good, I thought it was something dangerous. Looks like you'll need more stamina to use your quirk. It seems very strong if that's the case, come let's head home and figure this out together." before grabbing his hand and walking home thinking about the future for her grandson.
