I Secretly Develop Myself In The Demon World - Chapter 1 - Demon World

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.

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?
