😋I recommend " The Magical Girl of the Contract " to you. This is a magic school + mystery mystery novel. It is different from ordinary magic school novels. It may be a little slow, but it will definitely not disappoint you. I hope you will like this story of the contracted girl in the dark.
One of the best is 'Harry Potter' series by J.K. Rowling. It's set in Hogwarts School of Witchcraft and Wizardry. The story follows Harry and his friends as they learn magic, face dark forces, and grow up. The world - building is rich, with different spells, magical creatures, and a complex wizarding society.
The magic of a returner in the manhwa and anime is very special. It usually comes with hidden powers and unique traits that drive the plot forward and make the character stand out. Also, it might have some rules and limitations that add to the complexity and excitement.
The specialness of a returner's magic lies in its rarity and the way it gives the character an edge in various situations. It might have unexpected effects or be tied to a profound backstory.
