A world which was run by money, where wealth and material goods were what made one king, is suddenly changed into one which has a new power given to those without a way to change society. A world which values the lowest of the low instead of ignoring them and pretending they don't exist. The less wealth a person possesses, the more magical power they possess. Takeuchi Kei who just lost all of her money due to her father's gambling addiction and has gone into debt now has the power to change society at her will.

How does the world change when it no longer has the option of leaving behind anyone? When the person whose life was ruined gets powerful enough to wipe out whoever wronged them? Will Kei change society for the better?
