Isekai Maou to Shoukan Shoujo Dorei Majutsu - Volume 9 Chapter 1

The story is about a man who’s opposed to the now-common practice of implanting false memories, but is one day given memories of a fictional childhood friend. This fabricated happiness torments him, but then, to his surprise, he meets her – a girl who shouldn’t exist.

A broken man who ended his own life finds himself reincarnated into the game he used to play. However, instead of becoming the protagonist or a powerful antagonist, fate places him in the role of a minor villain—a mere stepping stone for the protagonist in the game's first arc.

For decades, the brave warriors of the Northern Army fought to keep the world safe from the evil Silent Night. But when the fourth-generation leader, Jin Kwan-Ho is accused of colluding with the enemy, he is forced to disband the sect and commit suicide to protect his son, Jin Mu-Won. With no family and allies left, Mu-Won leads a dreary life under close surveillance… until a surprise attack from the Silent Night gives him a chance to escape to the mountains.

There, the young warrior trains to master the fighting techniques of his predecessors, before the mysterious disappearance of a loved one brings him back to the mainland. Follow Jin Mu-Won as he embarks on a journey to avenge his father’s death and take down the villains who threaten to plunge the world into darkness!

As a useless spoiled wild child, Bai YiHan finally brought about the end of his family, chased away the one he loved and caused his own death. After rebirth, he decides to cleanse himself and work hard at being a good child. But a lot of things don’t seem to be as he expected…

Bai Pa + Bai Ma: My son’s so obedient. Someone must be bullying him. This cannot be forgiven!

Bai Big Bro + Bai Big Sis: If my little brother’s sensibility comes from his suffering, then I’d rather he be a spoiled brat forever!

Mu JingYuan: If HanHan hits you, you must accept it. Yet you dodged…The wind’s changing. Someone should be bankrupt to make HanHan smile.

Bai YiHan: …I was so wild in my past life. Your involvement are undeniable!

This story is speculative, speculative, speculative. Important matters must be said thrice. Everything is about speculative time-traveling.
