Pausing time, turning back time, reversing times of specific objects/person, and even predicting the future…

Taking advantage now that Su Lin has control of time within his grasp. Being able to stop time; can dodge incoming attack and avoid mishaps, Su Lin is steered clear of harm’s way. Reversing time; can forever never regret, no need to overthink when acting. Inverting time of specific object/person; can repair any object and heal any person, Su Lin becomes a miracle doctor. Predicting the future; can hide from natural disasters, can buy the winning lottery tickets and stocks, listening to Su Lin is always right.

- Description from Novelupdates

15 years ago the world discovered magic as well as mythical beings (basically beings from various legends) in another dimension. Humankind learned to summon these dangerous mythical beings and use their power to great effect. Seven countries formed contracts with these “mythical beings” and gained their allegiance as a result. The mythical beings will choose their summoners on their 14th birthday and give them a stigma. Schools have been set up to train summoners and magical swordsman (basically bodyguards that give the summoners time to cast their spell) as a result.

15 years later after the finding of magic Kazuki Hayashizaki is chosen as a summoner and given a stigma to indicate that. This is surprising since males aren’t chosen as summoners due to their low amount of mana compared to females. As the first male to be a summoner Kazuki is under a lot of scrutiny by almost everyone.

To complicate matters his sister (who’s a magical swordsman) is against him going into summoner school to train there as a summoner. Because summoners and magical swordsman have a cat mouse thing going on where summoners look down on magical swordsman as inferior so his sister naturally is against him going there. She’ll stop him even if it means going to war.

Kazuki however is determined to thrive in summoner school and has already determined to give it his all. Even if he’s the lowest ranked student (ranked E) and his fellow students intend to demean him he’ll prove himself as the strongest summoner.

Born as the daughter of the last martial artist of this era, that is Yeon. Her father is the world’s greatest fighter and is respected by everyone. The only problem was…… “I know it’s impressive, but I don’t have to follow in his footsteps, do I?” Her stubborn father’s dream was for his daughter to also follow the path of martial arts. Naturally, Yeon’s life was filled with grueling training. Living a dull life, Yeon’s only hobby was reading romance fantasy novels before going to bed. “If only I could live as a lady once……” After making a wish, Yeon fell asleep and entered a novel as if she were dreaming. However, her enjoyment is short-lived when she realizes that it’s not a romance fantasy, but rather a martial arts novel. “It was my dream to be a possessor, but of all things, it had to be a martial arts novel, and in the body of a supporting character who dies early!” Feeling indignant and weeping, she suddenly notices her own reflection in the mirror. It was a glamorous image. ‘Hold on. Does this mean… I could become a lady?’ Moreover, in this world, there was a man who looked exactly like the male lead in her favorite romance fantasy. He was handsome and talented, but with a wretched backstory. “Things are going to be different now.” The fate of a supporting character who dies early? Forget about it. Whether they’re followers of the devil or a heretical sect, even the worst villains don’t scare her. Why? Because she is the strongest possessor in history. This is the story of Yeon’s adventures in the martial arts world, as she stumbles along in pursuit of everything she desires.
