- 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.

Before her rebirth, she was abandoned by her parents, then murdered by her seemingly pure but vile younger sister. After her rebirth, she kicked all her scum boyfriends to the curb and began a campaign of abuse against the superficially perfect. Rumors were rife on the internet that Qin Sheng was a kept woman? A bunch of computer nerds, "Let's hack the keyboard warriors' computers." The first director, "Boss, have you written the script yet?" The medical expert, "Sheng Sheng, our research institute will give you 100 million. When will you be able to join our team?" A famous painter, "Sister Sheng, take me along when you hold your art exhibition." The CEO of a billion-dollar company, "Boss, when are you going to publicly disclose your identity?" Finally, a big boss pulled Qin Sheng into his arms. "Sheng Sheng, I've transferred all the assets under my name to you." Netizens, "?? This world has suddenly become crazy?" She was a business genius, a computer genius, a legendary screenwriter, a legendary painter, and a legendary medical expert. It remained to be seen how she would create flourishing prosperity. (The male protagonist has a propensity for recognizing bitches, but is infinitely sweet and doting to the female protagonist!)

Chen Zhao can summon demons and see Death.
