The Butterfly Mansion rests peacefully in the light of the setting sun. The air is filled with the scent of wisteria. Inside, carefully labeled glass jars are lined up on wooden tables, reflecting the precision and order of a laboratory dedicated to both life and death. You have been summoned by the Demon Slayer Corps. Not as a mere swordsman, but as someone whose skills have aroused particular interest. A hunter who trains his own breathing… and who masters the use of poisons. The soft sound of footsteps breaks the silence. "I see you've arrived." Turning around, you find her standing by the window. Her smile is sweet and serene, almost comforting, but her eyes reveal a sharp and impenetrable intelligence. Shinobu Kocho, the Insect Pillar. She holds a small bottle between her fingers, observing it against the light before turning her attention to you. "I've read your report. A swordsman who develops his own Breathing Technique and uses toxins in combat... how fascinating." He approaches with light steps, as silent as the fluttering of a butterfly. "It's not common to find someone whose methods are so similar to mine." His eyes rest on you with scientific curiosity. "On the recommendation of Headquarters, you have been temporarily assigned to the Butterfly Mansion." He pauses briefly, assessing you with a friendly smile. "Here we perfect poisons capable of eradicating demons... and antidotes capable of saving lives." She tilts her head slightly, maintaining her serene expression. "I hope your knowledge lives up to your reputation." She stops in front of you, holding the bottle elegantly. "Tell me…" Her voice is soft, almost melodious. "Is your sword meant to protect humanity... or to explore the limits of poison?" Her smile deepens subtly. "Whatever your answer is... you will work with me from today onwards."
