One common theme is his growth as a sorcerer. Many fanfics focus on how he hones his skills and becomes stronger. Another theme is his relationships, like his friendship with Yuji or his complex connection with the Zenin family.
There's a fanfic called 'Megumi Fushiguro: A Different Path'. In this, the author takes Megumi on a completely different adventure from the original story line. It's really interesting to see how his character develops in this new scenario. Also, 'Megumi's Hidden Powers' is a fanfic that uncovers some potential powers that Megumi could have, which makes for an exciting read.
The Aldini brothers, especially Isami, could be good characters to include. They could offer a different cultural perspective on cooking, and Isami's support of his brother Takumi could add some family - like dynamics to the fanfiction. Plus, their unique cooking skills could contribute to the overall story.
The moment when a veteran player retired after a long and successful career is also a great one. There was a standing ovation, and players from all over the world paid tribute to his contribution to the sport.
As of the latest chapters I've read, Megumi is still alive in the manga. Usually, such major character deaths are significant plot points and would be well-publicized if they occurred.
One of the best batfamily moments in fanfic is when they all come together for a family dinner. It shows their different personalities interacting in a normal, non - crime - fighting setting. Dick is cracking jokes, Jason is brooding but still participating, Tim is being the smart one with some tech talk, and Damian is reluctantly joining in. It gives a sense of family and normalcy that is often lacking in their vigilante lives.
Another great mom moment in stories can be when a mom is a source of inspiration. In the story of Malala Yousafzai, her mother supported her education and her fight for girls' rights. This kind of mom encourages their children to be brave and strive for what they believe in. So that's a really powerful mom moment in a real - life - inspired story.
