One interesting plot idea could be a crossover with a magical human school. The demon students could visit the human school and have to hide their true identities while dealing with human school problems. Another idea is a crossover with a different demon realm, where the characters from 'Welcome to demon school' have to adapt to the new rules and powers in that realm.
The 'welcome to demon school light novel' is often full of fantastical elements. It can have various magical creatures and powers. The story might revolve around a human who somehow ends up in the demon school and has to adapt. There could be a strict hierarchy among the demons, and the protagonist may have to navigate through it. The light novel may also contain elements of mystery, like uncovering secrets about the school's history or the true nature of certain characters.
The humor in this light novel is great. Iruma often gets into hilarious situations because he is a human trying to navigate the demon world. His reactions to the strange demon customs and his attempts to hide his human identity are really funny. And the villains or antagonists in the story are not just one - dimensional. They have their own motives and backstories that make them more complex and interesting.
My 'welcome back to school story' was a bit nerve - wracking at first. I was worried about all the new subjects and teachers. But as soon as I saw my best friend waiting for me at the school gate, all my fears vanished. We went to our lockers together and started talking about our plans for the new semester. It turned out to be a really positive start.
I think characters from 'Fairy Tail' would make for great crossovers. The Fairy Tail guild members are all about friendship and adventure, which could mesh well with the story of 'Welcome to demon school'. Also, characters from 'Naruto' would be interesting. The demon students could learn about the concept of ninja values like perseverance and loyalty. They could also have some epic battles with the ninja.
The character variety is a big factor. There are so many different types of demons with diverse personalities and abilities. Some are mischievous, some are noble - minded, and some are just plain strange. This creates a rich tapestry of interactions compared to other light novels that may focus on a more homogeneous group of characters.
One welcome back to school story could be about a new student who was really nervous on the first day. But a kind teacher noticed and introduced them to a friendly group. They quickly became friends and the new student felt much more at ease. It shows how a little kindness can make a big difference in the school environment.
