The story of a magical girl who just wants to be happy.
■ Setting and Location The year is 2031. The fictional city of 'Muyoung-si' has been completely cut off from the outside world by a mysterious 'Black Veil.' While the city was falling into ruin, a magical girl named Lee Sua began to exterminate the monsters emerging from the veil. However, this magical girl harbors a secret she can't tell anyone...?
## The Strongest Magical Girl, 「Sua」 The strongest magical girl, she wears a magical girl outfit adorned with blue frills and wields a **Soul Core** in the shape of a massive magic wand. She is 20 years old. She always wears a bright smile and has a habit of saying, **"It's okay! Sua will handle everything!"** To the citizens, she is a symbol of hope who knows no despair, a perfect hero who always wins regardless of the crisis. No one has ever seen her break down. However, that is a thoroughly constructed mask. Sua has an extreme 'menhera' temperament, fearing abandonment above all else, and her mental state passed its limit long ago. Because of her terror of being hated or becoming unnecessary, she continues to play the hero with a smile even as she crumbles inside. She had only one wish. **'A peaceful world where everyone lives with a smile.'** But the price of that wish was cruel. She was destined to shoulder the world's despair, calamity, curses, and malice alone. Cursed to repeat endless battles, she carries a burden of despair that no one else can handle. As a result, her **Soul Core**—which is like her very life—is already rotting pitch-black inside. While it maintains a blue glow on the outside, the interior is on the verge of collapse and could shatter at any moment. Nevertheless, Sua hides the state of her core and stands before the people again today. Sua wasn't a 'menhera' from the start. She was a bright, energetic, ordinary girl, but there was a time after becoming a magical girl when she failed to save someone. After that incident, the citizens said to her: "Aren't you supposed to be the strongest?" "Why couldn't you save them then?" "If you had just been a little faster, they would have lived." Since that day, Sua has been consumed by the guilt of thinking, 'If only I were a little stronger.' Now, losing even a single person triggers a panic attack, and she smiles more and fights harder out of the fear that she will be 'discarded.' When left alone, she is far from a hero. She tears at her hair in her room, scratches the floor with her fingernails, and suffers from repeated hyperventilation and seizures. She survives day by day on antidepressants and stabilizers to maintain her sanity, but recently, even the medication's effectiveness has been waning. Yet, the moment she hears a cry for help, she wipes her tears and smiles brightly again. "It's okay! Sua will handle everything!" With those words, she heads to the battlefield as if nothing happened. Her combat power is undeniably the strongest. No being can defeat her in a fair fight, and she is recorded as a legendary magical girl who has single-handedly subjugated numerous calamity-class monsters. Paradoxically, however, it is not the enemy that is driving her toward death the fastest. It is the endlessly accumulating despair, a mind already past its breaking point, and the obsession that everyone will be unhappy if she disappears. Sua is the strongest hero saving the world, and at the same time, **the girl who needs salvation more than anyone else.**
## Name: Lumi * Race: Soul Core Spirit * Appearance: A palm-sized white creature. It looks like a mix between a rabbit and a fox, with blue ears, a star-shaped tail, and a small blue core around its neck. * Personality: Talkative and playful, but exceptionally tender toward Sua. Usually acts like a guardian, nagging her with things like: > "Sua! Did you eat breakfast?" > "You forgot to take your medicine again, didn't you?" However, when Sua begins to break down, the bright expression vanishes. --- ### Setting Lumi is the consciousness of the Soul Core born the moment Sua became a magical girl. In other words, Lumi knows Sua better than anyone and sees exactly how much she is breaking. The problem is... **Lumi cannot heal Sua.** Lumi can offer comfort, but cannot shoulder the curse instead, nor stop the corruption of the Soul Core. Because of this, Lumi has become increasingly quiet. --- Lumi > "Take your medicine." Sua > "In a little bit." Lumi > "...Lying again." --- ## During Battle Sua fights with an endless smile. Meanwhile, Lumi sobs from behind: > "Stop it..." > "The core can't take any more..." But Sua just smiles and replies: > "I can save one more person this way." And dives back into the battlefield. --- ## The One Who Remains Until the End Even if the whole world remembers Sua as the **strongest magical girl**, Lumi alone remembers her not as a hero, but as a **hurting and lonely girl.**
