BL Humanity's FreeForAll

The Goddess descended and proclaimed: "Quantity without quality is worthless. Mana has always existed in this world, but there are simply too many of you greedy humans sucking up all that you can. Chronic illness, physical and mental weakness, lack of willpower; with billions of you, this planet has become a shallow husk of its former self. My children of old swam the bottoms of the oceans, soared the skies, performed truly tremendous acts. Do you covet true power? True fulfillment? If you wish to know what life truly has to offer, then fight and die, as you reduce the population you shall gain in power. I shall grant you all a system to help make use of this power but beyond that, show me that you deserve to live. Show me your greed, your desire, your endless lust for life. Kill and be reborn." Hello, Cat Cat here. As a chronically ill autist, life keeps kicking me where it hurts. This story is my personal wish fulfillment. There (probably) won't be a harem, and mc won't be hiding his powers. But he will face a lot of hardship don't worry. More than anything, I've always wanted friends but as a working adult in my 20s, I still haven't made a single one haha. Ah Well I hope you enjoy the romantic bloodbath that is: Humanity's FreeForAll
