A third storyline might be about a group of students who discover a hidden part of the academia. It could be an ancient library or a secret chamber filled with powerful artifacts. As they explore, they learn about the history of the place and also face various challenges and puzzles to uncover its secrets.
In some 'Little Witch Academia Tied Together' fanfiction, there might be a storyline where the witches participate in a magical tournament. This could involve intense battles, new spells being created on the spot, and rivalries between different teams. Or perhaps a story where a character gets lost in time and has to find their way back, all while learning about the history of magic in their world. And then there are those that explore the family backgrounds of the characters, like a character finding out they have a long - lost relative who is a very powerful witch.
The strict but fair professor characters can also be popular. They serve as mentors and often have their own backstories and hidden depths in the fanfiction world. For example, a professor who was once a great adventurer but now teaches at the academia.
One interesting storyline could be the three - tailed wizard's journey to master a new and powerful spell. Maybe he has to face various challenges and overcome his own self - doubts during the process.
Another possible storyline is a story focused on a half - wizard who is an outcast in both worlds. They don't quite fit in with the wizards because of their demigod side, and they're not fully accepted by the demigods either. This character then goes on a journey of self - discovery, trying to find their place in either world or create a new place for themselves where they can use both their wizard and demigod powers.
In some fanfictions, there might be a storyline focused on the origin of the 'Flame On' concept. It could be tied to an ancient civilization within the 'My Hero Academia' world.

They learn about the true power of the flame - on quirk and how it can change the balance of power in their world.
One interesting storyline could be about the little vampire's adventures in the modern human world. For example, how he tries to fit into a school without revealing his true identity.
There could also be a storyline where the little vampire discovers a long - lost vampire clan. He then has to decide whether to join them or stay with his human friends. This could lead to a lot of internal conflict as he weighs the pros and cons of both options. He might learn new vampire powers from the clan, but also have to follow their strict rules which could put his relationship with the humans at risk.
You could write a 'little hero academia fanfiction' where the heroes have to face a new type of villain that is immune to most quirks. This would force them to rely on their wits and teamwork more than ever. Also, a story about the teachers' early days as heroes and how they trained would be really cool. It could show how they developed their teaching methods based on their own experiences.
Another storyline might involve a character from Kingdom Hearts getting lost in the 'Little Witch Academia' world. For instance, Riku could end up there and have to work with Akko to find a way back. Along the way, they could exchange knowledge about their different worlds and powers. This could lead to some interesting battles against local villains in the 'Little Witch Academia' world who are interested in Riku's power.
One interesting storyline could be Mount Lady facing a new type of villain that can manipulate the earth in ways she's never encountered. This forces her to use her quirk in creative ways to overcome the threat.
