Most people don't choose reincarnation. Reincarnation finds their way to them. Perhaps they did something great in their life. Or maybe truck-sama wasn't looking where it was going. But without fail, those who reincarnate are destined for something great. A new life where everything changes for the better. But... Reincarnation isn't always the greatest thing. Sometimes you just draw the short end of the stick. Di Tou just happens to have drawn the shortest stick. Pulled out of his life randomly. Taken by a crazy old eccentric man not as a disciple, but as a body double?! And a janitor body double no less?! Grasping a system to find... It's a JANITOR SYSTEM!? Truly, how unlucky can one get?
Having finally bested its foe of many years, how could it be content with the little parcel of sky it had known since it had grown up? Although its parents had once told it that the world was vast and the far skies were not the territory of their clan, that was also moments before they had dropped him and his brothers down a gorge to fight for survival. As the ultimate winner in both that game of survival and in the fight between it and its parents, it prevailed time and time again. How could the word of the defeated be compared to that of the victor?
For them, this small parcel of sky was the limit, and their clan was their burden, but it… it had broken free from that chain and had collected the strength of the collective into one body, so how could it be so easily faltered?
