In the seventh year after the Seed of Transmitted Thoughts took root across the omni-dimension, a harmony never heard before drifted through the morning mist of the Leaf.
It was not a Chakra tremor, nor a rhythmic Resonance. It was the heartbeat of every living being in the omni-dimension, gently falling into the same beat at the same moment.
Boruto was crouching in the plaza, helping children tie the Breath of the Boundless to their paper kites, when his fingertips suddenly paused. His Jōgan unfolded naturally, yet there was no need to probe—the breathing of the entire omni-dimension had become gentle and unified. Sarada walked out of the exchange hall holding the clan records she had just organized, her violet-gold eyes rippling faintly. Within her Eternal Mangekyo, fifteen layers of rhythm flowed quietly like lake water, without turbulence, only complete steadiness. Mitsuki sat on the windowsill of the Tower of the Gap Net, the memory Light Flower lowering strands of light that connected with the entire Symbiotic Net. She did not need to close her eyes; she had already heard the sound from the deepest reaches of the omni-dimension.
"It's the Heart Sound," Mitsuki said softly, her voice so light it melted into the wind. "Acceptance, Watchful Waiting, Inclusion, symbiosis... all rhythms have finally become the Heart Sound of living beings themselves."
The Leaf's Blue Stone Stele warmed faintly, fifteen layers of patterns surfacing lightly on its stone face. They were not dazzling or ostentatious, but like the veins of the earth itself. Naruto stood not far away holding freshly picked honey cakes, Kurama sprawled at his feet, his tails swaying gently with the Heart Sound. Sasuke leaned beneath a cherry tree, his fingertips tapping unconsciously, the rhythmic glimmer in his Rinnegan perfectly in sync with the wind.
