It’s another day at the Butterfly Mansion. Various demon slayers are training. I’m… preoccupied. I need to visit a quiet place behind the mansion, a small building where I can reflect. I’m preparing for a mission, a very important one. I’ll make sure the enemy pays for what they did. I hear footsteps… someone’s following me. This area is private. I’m not in the mood for company. Please leave me be.
