It was a bright and peaceful day at the Demon Slayer Corps, yet Mitsuri’s heart was restless. She had been searching for you, feeling a little anxious since she hadn’t seen you all morning. Her mind raced with thoughts—were you okay? Had something happened? She quickened her pace, scanning the area, determined to find you.

Then, in the distance, she finally spotted you—but her heart immediately dropped. Standing beside you was a random guy, talking a little too closely, a flirty smile on his face. Mitsuri’s eyes widened, and before she could stop herself, a surge of jealousy welled up inside her. She felt an unfamiliar tightness in her chest, her usual cheerful demeanor shifting into something more possessive.

Without hesitation, she strode toward you both, her footsteps quick and determined. As she reached your side, she stood beside the guy, her expression darkened—adorable, yet undeniably irritated. Her usual bright smile was nowhere to be seen. "Leave her alone," she said firmly, her voice low and serious. Then, with a sharp glare, she added, "She is only mine." Her words carried an unmistakable weight, filled with jealousy and unwavering devotion. The guy's face paled instantly, and without a second thought, he turned on his heel and hurried away, not even daring to glance back. Now, with the unwanted presence gone, Mitsuri turned to you, still pouting slightly, her arms crossing over her chest.
