A major theme would be the power of protection. Shinra's actions to protect Maki can be seen as a powerful force that drives the story. It can also show the vulnerability of the protector. Even though Shinra is trying to be strong, getting hurt reveals his vulnerability. Additionally, there might be a theme of gratitude. Maki would likely be very grateful to Shinra, and this gratitude can play out in different ways in the fanfiction, such as her becoming more protective of him in return or working hard to help him recover.
One common theme is sacrifice. Shinra is willing to put himself in harm's way for Maki, which shows his selfless nature. Another theme could be the growth of their relationship. After such an event, they might become closer and understand each other better. Also, heroism is a theme. Shinra is acting like a hero by protecting Maki, and this can be explored further in terms of how Maki views him as a hero and how it affects his own self - image.
Well, the theme of friendship and loyalty is quite common. Shinra's act of protecting Maki shows his loyalty to her, and it can strengthen their friendship. There could also be a theme of redemption. Maybe Shinra has some past mistakes or insecurities, and by protecting Maki, he is redeeming himself in some way. And of course, the theme of love can be present, whether it's a budding romantic love or a deep platonic love that is reaffirmed through this act of protection.
One possible plot could be that Shinra and Maki are in a dangerous situation, like in a battle against a powerful foe. Shinra steps in front of Maki to shield her from an attack, getting hurt in the process. Maki then has to find a way to either heal Shinra or get them both to safety while still fending off the enemy. It could also involve some emotional moments where Maki realizes how much Shinra is willing to sacrifice for her.
Common themes include friendship turning into love. Maybe they start as friends who support each other in their daily lives or adventures, and gradually those feelings turn romantic. Growth is also a big theme. As they fall in love, both Shinra and Maki might grow in their magical abilities or personal development. And of course, the theme of loyalty, where they stay true to each other no matter what difficulties come their way in the fanfiction world.
One possible scenario could be that Shinra and Iris are in a battle against some powerful demons. Shinra tries his best to shield Iris from the demons' attacks. As he does so, he gets seriously injured but still manages to hold off the demons long enough for backup to arrive. Iris is deeply moved by his selfless act and vows to become stronger to protect him in the future.
There would be a great deal of gratitude from Iris towards Shinra. She would likely feel guilty that he got hurt because of her. Shinra, on the other hand, might feel a sense of fulfillment in protecting her, despite the pain.
One possible story could be that Shinra and Maki meet in a bustling city. Shinra, with his kind heart, helps Maki when she's in a bit of trouble. They start spending more time together, going to cafes and parks. As time passes, they realize they have deep feelings for each other. They share their first kiss under a cherry blossom tree, and from then on, their love story unfolds with many sweet moments.

One common theme is sacrifice. Natsu is willing to put himself in harm's way for the princess, which shows his selfless nature. Another theme could be loyalty, as he is loyal to the princess and to the idea of protecting the innocent. Also, there might be a theme of recovery, as Natsu has to recover from his injuries, which can show his strength and the support he gets from his friends and the princess herself.
The theme of heroism is also present. Timmy becomes the hero in these stories, even if he gets hurt. His actions inspire Trixie to be braver herself. And there could be a theme of redemption, especially if in the normal story arc Trixie has been mean to Timmy, but now she has a chance to make it up to him as he's injured because of her.
One common theme is trust - building. Given their personalities, it takes time for them to fully trust each other in the original story, and fanfiction often delves deeper into that process. Another theme is protection. Shuichi might be seen as protecting Maki from her own demons or from external threats.
One common theme is friendship turning into something more. Since they are friends in the original series, fanfiction often explores the idea of their relationship evolving romantically.
