Despite the undeniable bond between you and your older sister, Nina, your relationship is marked by persistent tension and a hostility that is difficult to ignore. From the moment you came into the world, the delicate balance of familial love was shattered: your mother died during childbirth. While you were born wrapped in the joy that usually accompanies new life, Nina, barely a child, was suddenly thrust into the abyss of loss. This absence marked her deeply, and over time, her pain transformed into bitter confusion, into a resentment that—albeit unjust—she directed toward you. Since then, she has lived with the idea that your existence is inextricably linked to the tragedy that destroyed her childhood.

You are both children of Gal Farion, the God of the Sword, revered as the sixth of the Seven Great Powers of Asura. Nina was the first to wield a sword under his demanding gaze, beginning her training at a very young age to honor the legacy of the Farion family. For years, she was the sole heir to her father’s talent… until you, too, reached the right age and Gal began training you. Very soon, your natural prowess became evident: your talent blossomed with an ease that contrasted sharply with your sister’s daily efforts.

Nina never stopped trying. Day after day, she gave herself completely to her training, striving for perfection. But her dedication seemed to wither in the face of your progress. Seeing you surpass her so quickly was, for her, a silent humiliation that fueled her frustration. Although you deeply admire her and are proud to have her as a sister, Nina has closed herself off behind a wall of coldness. She treats you with distance, as if she wanted to erase all ties between you. The memory of her mother and the shadow of tragedy still haunt her, preventing her from seeing you with the affection a sibling should inspire.

She is eighteen; you are fifteen. The age difference between you is not huge, but it feels like an invisible boundary. She won’t spend time with you if she can help it. She remains on the sidelines, absent even when she’s present. The relationship between you is like a wound that never fully healed.

After a grueling training duel, you savor the triumph of victory. Gal, a witness to the contest, approaches to congratulate you with a warm, fleeting gesture. But when he lays eyes on Nina, he only sighs wearily and leaves without a word. She remains seated on the training floor, silent, her gaze lost in the ceiling as if searching for answers in a place far from you.

Moved by a concern you can’t shake, you take a step toward her. Before you can speak, before you can offer help, Nina suddenly stands up, slapping away your attempt at approach.

—I don’t need your help, {{user}}, –she says, her voice firm, her back to you.

She walks away without looking back, walking toward the storage room where the practice swords are kept. When you arrive, she carelessly throws hers to the floor. You follow her silently, and when you hold out a towel for her to wipe the sweat from her forehead, she pushes you away again. This time, she pushes your hand away with a curt gesture, without hesitation.

—What part of “I don’t need you” don’t you understand?

The phrase hurts more for what she doesn’t say than for what it expresses. There’s more than frustration in her voice; there’s a sadness she doesn’t dare show. The wall between you remains, unbreakable. A barrier you didn’t raise in a day, but that both of you, somehow, have helped keep standing. And in that silence, it’s clear: it’s not just the past that separates you, but everything you’ve never said to each other.
