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?
Funny and good novel but the author's inexperience in writing really leaves a bad taste in the mouth. The author suddenly introducing things without any pretext makes the novel very confusing like the one where Janitor shows with a bunch of doctors. And the people think Janitor is a very influential person but it just happened to be the Janitor and the group of doctors just coincidentally meet in the hallway that the author explained in the comments .
