The Simple Life of Killing Demons - Chapter 30Book 10:

Three years after graduating from Hogwarts, Felix entered the school again, only this time as a professor!

What kind of sparks will come from the combination of Muggle wisdom and magic?

Shen Yansheng always thought that she didn’t like Lu Jingce until one day she heard that a certain group boss intended to marry his daughter to Lu Jingce. She was so angry that she couldn’t eat anything that night and locked herself in the room after returning home. When Lu Jingce came back in the evening, he took the key from the study, opened the door and entered her bedroom. He sat beside the bed, leaned over and kissed her to wake her from her sleep. She looked at him angrily, but he smiled happily and asked, “Jealous?”

Shen Yansheng and Lu Jingce have been falling in love all the time, mainly because she hadn’t figured out how to explain their relationship to her parents, which caused her parents to always think she was single, so they took the initiative to trick her into going on a blind date. But someone happened to have a dinner in that restaurant that day, and saw her and her blind date sitting at a table for dinner from a distance. She felt a gaze looking at her from behind, and when she turned her head, she met someone’s handsome face that was half-smiling. That night, as soon as Shen Yansheng came home, she threw herself on someone, raised her hand and swore, “I can explain it!” Someone still had that half-smile and pinched her cheek, “The explanation is invalid.”

Amakawa Haruto died before he’d the chance to reunite with his childhood friend who disappeared five years ago. Rio, a young boy living in the slums seeks revenge for his mother who was murdered in cold blood in front of him when he was only five years of age.

There exists the earth many knows of and there exists an alternate world. Two people, each with their own backgrounds and values. For odd reasons, the memories and personality of Haruto, one who should have died resurrects in Rio’s body. As the two are confused over their memories and personality fusing together, Rio (Haruto) decides to live in this new world.

Along with Haruto’s memories, Rio awakens an unknown but special power. If he’s to use it, it looks as if he can live a better life, but before that, Rio encountered a kidnapping which results in involving the two princesses of the Bertam Kingdom.

After saving the princesses, Rio is given a scholarship to attend the Royal Academy, a school for the rich and powerful. His background being a poor orphan who once lived in the slums, the school full of nobles was rather a detestable place to stay at.
