Chapter 3

Kain Elgrandor is the eldest son of the Elgrandor Duke family and the older brother of Dianah Elgrandor. He is well-versed in both academics and martial arts, handsome, talented, and composed, a cool beauty. He is supposed to become a perfect, older target for the player to pursue in the future.

Kain has the memories of his previous life.

In his past life, Kain was a salesperson who mainly worked outside during the day and a YouTuber who made game playthrough videos with moderate views at night. The continuous all-nighters spent on intense gaming and video editing, along with excessive energy drink consumption, took a toll on his body. He closed his eyes for a brief nap at his desk and never woke up. He had chosen a job at an extremely white-collar company that allowed him to leave on time (though with a low salary) because he wanted to play games, but he ended up dying from overwork.

Kain realized he had been reborn with the memories of his past life. He was born into a high-ranking noble family and was raised by kind parents and a nanny, living a life of comfort. He was grateful for his current, more fortunate circumstances compared to his relatively young and premature death in his past life and resolved to live a long life and be filial to his parents this time around.

When his sister, Dianah, was born and named, Kain realized something. This world was the world of the game "Unlimited Magic Academy ~There's No Limit to Love!~" that he had just cleared and was editing videos for before he died.

"Of all things, I'm reborn into the world of a dating sim..."

He had played countless other games, including an open-world samurai RPG, a Final Fantasy-like RPG, and a mysterious dragon RPG. He wished he had been born into one of those worlds, where he could have become a hero. Kain was a bit disappointed.

Realizing he had been reborn into a game world, Kain tried to bring up status screens, configuration menus, and command menus, but to no avail. Despite being in a game world, it was very much real.

This is a game, but it's not a plaything.

Without the ability to save and load, knowing the scenario to some extent provides no real comfort. It's impossible to feel safe. Tomorrow, he might be run over by a carriage on the street or die from a bad fall down the stairs. As long as this world is real to him, even if it is a game world, these dangers remain unchanged. Kain vowed to live sincerely and without complacency.

Now, about Kain's sister, Dianah Elgrandor.

Kain's sister, Dianah Elgrandor, is a character in the game who plays the role of the villainous lady. As the eldest daughter of a duke, she is of high status, well-educated, and possesses a lot of magical power. She is a perfect lady, excelling in singing, playing instruments, painting, sports, and etiquette. Due to the continuous lineage of noble blood, she is also exceptionally beautiful, truly a paragon of talent and beauty.

Her only flaw is her bad temper. She often competes with and provokes the game's protagonist, making baseless accusations. As a rival character in the game, her role is to provide the player with a sense of satisfaction by giving her a comeuppance at the end, so the worse her character, the better.

However, this is only true during the game's playtime, from ages 12 to 18.

When Kain first saw the newborn Dianah, he was overwhelmed by her cuteness. "So cute! She's a real angel. I could die of respect," he exclaimed, leaning back so far that his spine almost snapped. His parents were worried and tried to hide Dianah, thinking, "Mother, we must hide her quickly, or the gods will take her back. She's an angel who was mistakenly given to us." They even covered Dianah's head with a blanket and kicked Kain out of the room.

Until his mother recovered from childbirth, the nanny was responsible for taking care of Dianah, but Kain often came to the nursery to help. At first, the nanny and maids were wary of Kain due to his strange behavior after Dianah's birth, but as he only observed Dianah and followed the nanny's instructions, doing chores diligently, he gradually gained their trust. Even at the age of three, Kain could help by lying down with Dianah, which made her sleep soundly without crying, much to the relief of the nanny and his mother.

As Dianah grew past her first birthday and began to walk, her cuteness only increased. When Kain called her, she would laugh and waddle over to sit on his lap. Her fluffy blonde hair, sea-blue, round eyes, and maple-leaf-like, drooling hands were all incredibly adorable. She would eat her weaning food quietly when Kain fed her with a spoon, and he became more and more smitten with her.

Kain is now five years old, and his three-year-younger sister is two. Despite still being a clumsy walker, she always follows Kain around, which is very cute. When she falls, she doesn't cry immediately but looks for Kain, and only when their eyes meet does she start to cry. She's incredibly cute.

In his past life, Kain had worked in educational toy sales and often visited kindergartens and nurseries. He had interacted with young children quite a bit and was somewhat experienced in handling them. He had even played with children to test the reactions to toy prototypes. When they played house, and Dianah, with an angelic smile, stuffed a block into Kain's mouth saying "Ahhh," or when she handed him a tassel torn from a curtain saying "Here you go!"—these moments became Kain's treasures. He even framed and displayed a crayon drawing on the wall that he believed was a portrait of himself. Kain's love for his sister was profound.

Dianah has been learning violin and piano since the age of three. When Kain starts practicing, she comes over and dances, wiggling her bottom. It's incredibly cute. She's a real angel, isn't she?

Despite being such a cute angel, she is supposed to be condemned, exiled, or married off to some unknown old man in the future. Are these people crazy?

The game's ending is at the protagonist's graduation from the magic academy, which is 16 years from now. Dianah will enter the magic academy in 10 years. The idea that this angel will become a villainous lady in 10 years is unbelievable. It's impossible to believe.

Depending on the route, Kain might even be the one to put his sister in a difficult situation. He clenches his fist tightly, determined not to let that happen.

"Big brother?"

Kain's angel looks up at him with her big, round eyes. "I'll definitely protect you. I'll definitely make you happy." He speaks to her in his heart, gently strokes her head, and smiles at her. In response, his angel laughs and excitedly reports, "I peed!"
