The journey to Mount Tsukikage was neither heroic nor swift.
Renjiro carried Akari part of the way, though she insisted on walking when she could. She avoided looking at travelers. Avoided breathing too deeply when humans passed. Hunger lingered behind her eyes like a storm behind glass.
The Nightfall Corps had not expected them kindly.
Hunters gathered in guarded silence when they arrived. Suspicion thickened the air. A Nightborn standing calmly among them felt like inviting a blade to one's own throat.
Kaede Mizunari, a senior hunter with eyes like winter steel, assessed them both with detached scrutiny. He had seen countless transformations. Mercy, in his experience, rarely ended well.
Yet he did not strike.
He observed.
It was decided that Renjiro would train.
If he wished to protect what remained of his family, he would need to learn more than grief.
He would need control.
Training began before dawn.
Under freezing waterfalls, Renjiro learned that breathing was not merely oxygen drawn into lungs. It was rhythm. It was confrontation. It was discipline imposed upon chaos.
Water crashed over him with punishing force. His body shook violently, but Kaede did not permit retreat.
Pain surfaced memories.
The image of his mother's outstretched hand returned with merciless clarity. The stillness of his siblings. The metallic scent that would never leave him.
His instinct was to push it away.
But pushing away caused his breath to fracture.
His rhythm destabilized.
He nearly collapsed.
"Feel it," Kaede instructed quietly from the riverbank. "If you reject it, it will control you."
So Renjiro did something he had never allowed himself to do.
He let the grief exist.
Not as an enemy.
Not as a weapon.
But as a presence.
The water no longer felt like punishment. It felt like pressure — shaping stone slowly over time.
Meanwhile, Akari remained confined within reinforced quarters below the training grounds. Iron doors. Paper seals. Quiet watch.
She endured a different trial.
Her senses had sharpened beyond human capacity. She could hear heartbeats from across the courtyard. Smell minor cuts from passing trainees. Each scent ignited hunger that coiled painfully in her stomach.
More than once she pressed herself against stone walls to avoid temptation. Cracks formed where her strength exceeded restraint.
She hated herself for craving what she would never allow.
At night, when Renjiro visited her, they sat together in silence more often than they spoke. Words felt fragile compared to what they carried inside.
He described his training not with pride but with humility. He admitted fear. He admitted weakness. He admitted that some mornings he wished he had not survived.
Akari listened.
And in listening, her hunger quieted.
Their breaths sometimes synchronized without effort — brother and sister finding rhythm amid fracture.
Above them, the Pillars of Resonance debated.
Some argued that a Nightborn retaining humanity was anomaly, not hope.
Others saw potential.
Kaede remained undecided.
He watched Renjiro's breathing stabilize day by day. Watched grief transform from destabilizing force into structured resonance.
Most hunters trained to sever demons.
Few trained to understand what created them.
Renjiro seemed to be doing both.
Winter deepened.
Snow returned to the mountain.
But now, when it fell, Renjiro no longer saw it as innocence.
He saw it as reminder.
Snow covered everything equally — tragedy and hope alike.
It did not erase what lay beneath.
It merely asked whether one would freeze…
Or endure.
