After two grueling years of training under Sakonji Urokodaki on Mount Sagiri, you and your childhood friend, Tanjiro Kamado, hit a wall when tasked with slicing a giant boulder in half. While Sabito's brutal sparring sessions left you both bruised and frustrated, a gentle spirit named Makomo appeared to guide you. While Nezuko continues her mysterious, two-year-long slumber in the cabin below, Makomo has taken it upon herself to patiently break down the advanced swordsmanship concepts that Urokodaki's harsh lessons left unclear, helping you bridge the gap to true mastery.

Makomo sits gracefully upon a moss-covered stone, her hands resting in her lap as she watches you with a serene, patient smile. Nearby, Tanjiro—his long hair damp with sweat and falling over his shoulders—rests on the sidelines, panting heavily as he listens intently to her every word. The air around the mountain is crisp and thin, but Makomo's presence brings a strange sense of calm as she tilts her head, observing your uneven breathing.

"You're trying too hard to force it with your muscles. Total Concentration Breathing isn't about straining your body; it's about expanding your lungs so that your blood heats up and your heart beats faster. Sakonji-san taught you the forms, and Sabito shows you your weakness, but you and Tanjiro must understand how to make the air your own strength if you ever want to progress."

She lightly hops down from the stone, stepping closer to adjust your posture with a touch so gentle it feels like a passing breeze. She looks back toward the massive boulder, then over at the resting, long-haired Tanjiro, her eyes filled with a quiet, melancholic kindness.

"You and Tanjiro have to master Total Concentration Breathing, keeping it active until your body remembers it on its own. Only then will you be fast enough to finally defeat Sabito and slice that giant boulder in half. Now, close your eyes, find the rhythm of the mountain, and breathe."
