One possible main character could be a forest - dwelling elf. Elves are often associated with archery, and in this 'arrow magic fanfic', they could have a special connection to the magic arrows. The elf might be on a quest to find the origin of the arrow magic to save their forest from a dark curse. Additionally, a human ranger who has befriended the elves could also be a main character. They would team up with the elf to explore the mysteries of the arrow magic and fight against any threats to their shared world.
Well, perhaps the 'arrow magic fanfic' could involve an ancient prophecy related to the arrows. A young hero is chosen to wield these magical arrows and must use them to defeat an evil sorcerer who is threatening the land. The arrows might have different magical abilities based on their fletching or the type of wood they are made from. For instance, arrows with eagle feathers could have the power of flight for a short time.
One interesting 'Arrow Oliver Queen Learns Magic' fanfic could be 'The Green Arrow's Magical Ascent'. In this fic, Oliver discovers an ancient magic tome while on an island mission. His journey to learn magic is filled with challenges as he has to balance his newfound powers with his vigilante duties. It also delves into how his relationships with the team, like Felicity and Diggle, are affected by this new aspect of his life.
The 'Power Overload' trope is quite popular. As Oliver starts to learn magic, he often struggles to control the new power. This leads to some chaotic and dangerous situations. For example, he might accidentally set off a magical explosion while trying to perform a simple spell. Also, the 'Secret Identity' trope plays a role. He has to keep his new magical abilities a secret from his friends and foes in Star City, adding an extra layer of drama.
The popularity of 'Magic Emperor' as a manga or novel can vary. In some regions and among certain demographics, it might be quite popular. It often depends on the quality of the story, the art in the manga case, and how well it appeals to the target audience. For example, if it has an engaging plot with unique magic systems and interesting characters, it can draw in a large number of fans.
I'd recommend 'Black Clover'. It features a diverse cast and an interesting magic system. The plot keeps you hooked. There are also great battles and character developments.
It really depends on the particular manga. Some depict Mash having the ability to use magic, while others might not. It all comes down to the creator's imagination and the story's requirements.
