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?
Finishing on this powerful line, Di Tou let the classroom sit in silence for a few moments before he coughed and said, "Of course, that being said, I feel I have the obligation to note that although you shouldn't feel ashamed of who you are, if you find that you have destructive thoughts towards society, it's still best to restrain such thoughts. Ultimately, we live in a society of order and regulations. One's individual will can't determine everything."
