Another plot could be set in a different realm. The reader somehow gets transported to Thoth's realm. Thoth is tasked with showing the reader around and protecting them. The reader is amazed by this new world and is drawn to Thoth's intelligence and grace. They face challenges together in this realm, which brings them closer, and a love story blossoms between them.
Maybe the reader has a special power that they are unaware of, and Thoth senses it. He decides to keep an eye on the reader to figure out what this power is. In the process, they get involved in various adventures together. Thoth helps the reader control their power, and during these intense times, their relationship deepens into a romantic one.
Perhaps the first meeting could happen during a class or a lecture. The reader is sitting there, a bit bored, when Thoth stands up to give a presentation. The reader is immediately drawn to his confidence and knowledge. After the presentation, the reader goes to ask Thoth a question, and that's when they really start to interact. You can add some humor to this, like the reader being a bit nervous and stumbling over their words, which makes Thoth smile.
A plot could involve Loki accidentally putting Balder in danger while trying to prove himself. Then he has to go to great lengths to save Balder. This would show Loki's growth as he realizes the importance of Balder's life.
Another fanfic idea could be a more romantic one. For example, Balder is initially hesitant to show his feelings for Yui because of his status as a god, but as time passes, he can't resist his emotions any longer. Yui, on the other hand, has always been secretly in love with Balder and when he finally makes a move, it's a beautiful moment of two different worlds coming together in love.
One possible scenario in a Loki x Balder fanfiction could be their initial encounter. Maybe Loki, with his mischievous nature, tries to play a prank on Balder, but Balder's pure and kind heart makes Loki's attempt backfire in an unexpected way. This could lead to an interesting dynamic where Loki starts to see Balder in a new light.
First, you should familiarize yourself with the characters of Balder and Yui from 'Kamigami no Asobi'. Think about their personalities, their goals, and what makes them unique. Then, come up with a basic plot idea, like a meeting between them that starts their story.
One idea could be a story where the reader is a new hero in the Injustice 2 universe. Superman, initially suspicious, starts to see the good in the reader. As they team up against common threats, a bond forms between them. Maybe the reader has a unique power that Superman comes to rely on.
One idea could be that the reader is a new student at the university where Tadashi studies. They meet in the robotics lab and start collaborating on a project, which leads to a budding friendship and then romance.
A really interesting plot could involve the reader being a Muggle - born who discovers a magical ability that no one has ever seen before. The Weasley twins, being curious and always interested in the extraordinary, take the reader under their wing. They explore this new ability together, getting into all sorts of adventures and misadventures at Hogwarts. This could also lead to a romantic relationship as they get closer through their shared exploration.
A good plot might be that the male reader is an outcast in the village because of some special power he has. Kakashi is the only one who doesn't fear him and decides to understand him better. As they spend time together, they find that they have a lot in common and start to fall for each other. Or perhaps they meet during a time - travel incident where they have to fix something in the past. This adventure brings them closer and they realize their love for each other.
One idea could be that the male reader is a dragon in human form from another dimension. He comes to the HTTYD world to seek help because his own dimension is in danger. The Vikings initially suspect him but as they learn more about his situation, they team up with him. Another plot could be that the male reader's dimension is slowly being consumed by the dark forces of the HTTYD world's past. He has to work with Hiccup and Toothless to find a way to stop it before his dimension and the HTTYD world are both destroyed.
