Dual Doomsdays: My Sister Stole My Beastman, but Misfortune Followed Her

The high-temperature apocalypse arrives, along with a Beastman System.

Those with high college entrance exam scores get first pick of high-ranking beastmen. My younger sister and parents forced me to give up the Snow Python, so I had no choice but to spend all my points on the Fire Fox.

The heat apocalypse soon ended, only for a deep freeze to follow. The three of them failed to survive the cold and froze into ice sculptures.

The Fire Fox had long been in love with my sister. After she died, he plotted to kill me.
