Fate Grand DxD

My name is Max, with the help of a ritual I find by accident I summoned 14 special helpers in my objective of survival, but why does it seem like the world REALLY wants me to die? Seriously, it is like there is the end of times coming or something. Well, I am the heir of Mammon, the Demon of Greed, so I will end up winning in the end, no matter what.
