This is a story about constraint and freedom, destruction and rebirth, and the search for one's true self within the cage of perception.
【When the ultimate secret of the tomb-raiding world enters the labyrinth of the human heart, and an immortal is shackled by modern society】
Yumiya Siyuan: his name is a secret in itself. He has lived for over eighteen hundred years, is Zhang Qiling's older brother, is the very “ultimate” that tomb raiders seek, and was once the leader of the mysterious organization “Silence.” He carries the bloodlines of the Ink Qilin and the Candle Dragon, and his blood holds ten times the power of Qilin Exhaustion. Yet this being, after a single act of “heroism,” is exiled to Tokyo alongside his younger brother Yumiya Lian and branded a “problem youth.”
Between the bustle of Shibuya and the quiet of Yongen-Jaya, Siyuan enters Shujin Academy, a new maelstrom, dragging along the semi-invisible shackles of perception.
The warped teacher Kamoshida, a strange phone app, a world of perception capable of rewriting people's hearts... Everything challenges what he has always believed.
And as he suffers from “ALS,” “mania,” and “multiple personality disorder,” he struggles against the poison and madness within him while his five senses gradually fade.
His past follows him like a shadow: the protection of the Silence organization in Yokohama, the concern of old friends from the Port Mafia and the Armed Detective Agency, the support of China's “Iron Triangle,” and his mysterious partner Cheng Yiyuan, who gave him a black diamond ring... The forces at play intertwine in the shadows of this modern city.
As he rides his reborn Kawasaki motorcycle, bearing his eternal shackles and will to redemption, and travels along the boundary between reality and perception, a gamble over destruction and renewal has already begun.
