Kejing City, a super city of professional alienation. Part-time sorter Yun Juyou handles discarded magic tools every day, but is trapped in system hibernation due to energy exhaustion. Late at night, resentment leaked out of a scrapped refrigerator - it was the hundred years of loneliness of the abandoned shikigami. As soon as Yuu's hands touched the surface, the system suddenly revived: "High-purity emotional residue was detected. Is it decomposed?" At the moment of decomposition, the energy tank surged. But the price came: Wanjie Chat Group @him, an Onmyoji from the Heian Era issued a regrettable mission - to say "Sorry" to her best friend on her behalf. Yu accepted the mission and used his recycling ability to decompose the remaining regrets of the opponent, in exchange for the rare spell "Pure Words". But the emotional residue attached to the mission made him dream of farewell under the maple leaves every night. What's even more troublesome is that the heir of the demon-slayer family in the same school, Ryuudo Keke, is eyeing him: "You have the aura of the Abe family." Yuma Yugiri, a special section of the Metropolitan Police Department, handed over the agreement: "According to the apparent agreement, please cooperate with the registration." Yuu just wants to recharge in silence, but the tasks of the Bankai Group are getting heavier and heavier each time - sending home letters for the onmyouji who died in the battle, and helping the amnesiac shikigami to find their names... Each recovery will tear the wound, but it also brings him closer to the truth: the source of the professional alienation that Kejing City is indulging in is actually a betrayal that was covered up a thousand years ago.
