Dimwit's Journey

I was summoned to the world of Hasnir as a hero. During my summoning i was asked what level should the demon lord be. Obviously a demon lord that is weaker would make my job much easier so i decided on him being level one.Well it seems it doesn't work that way as the first monster i encountered a girl that looks like she is 13 complaining that i stole her pow0ers and caused her title as the demon lord.
