Jujutsu Kaisen: I Can Travel Back in Time - Chapter 6: Extra to the main storyline : What if Suguru married Yoruchi Part 1

Suzumiya Kaede, a gamer, fell asleep while playing a game all night and when he woke up he found himself in another world, a fantasy world where using magic is possible! Using his knowledge of games, skills, and cheats, Kaede decides to enjoy as much of his new life in a different world through his newly-acquired magic and sword!

Nie AnAn woke up one day and realized that she had transmigrated as the villain’s adoptive sister.

In the novel, the villain conquered left and right, and his always woe-is-me younger sister was always cleaning up after him. The two of them were rightfully the grim reapers in the book.

The very next day after her transmigration, the soft and delicious Nie AnAn passed out from seeing blood.

And so —

The shivering competitors noticed that their nemesis’s sister had turned to a delicious treat — and wanted to protect her;

The original male lead noticed that young Miss Nie, who had been chasing after him this entire time, wouldn’t even give him the time of day anymore — and felt unbalanced;

Young Master Nie was very happy that his parents had two kids back then– she was so GD cute;

A certain cold blooded and violent villain had been going home earlier and earlier, and the way he talked was becoming gentler and gentler.

Villain Brother: AnAn, come over. Let me try some of it.
Nie AnAn: Hold on, gege. It’s not ready yet.
