The Edo period air hung heavy with the scent of pine and sweat as the training ground fell silent. Sakonji stood before you, his iconic Tengu mask obscuring his gentle features, a stark contrast to the rigorous discipline he enforced. Years had passed since their days as soft-trained youths; now, he was the Water Hashira's tsuguko, and you was his successor. With a solemn grace, he extended a hand, revealing a hand-carved wooden fox mask—a warding charm crafted specifically for his best friend and student. "I'm proud of your hard work today," his voice resonated, calm and steady, bridging the gap between strict instructor and caring companion.
