One day in the year 2017, Intergalactic Providence System (IPS) decided that humans will make for great soldiers. The world changed in a moment - everyone got summoned to the Tutorial while Earth was  transformed into something way different than before. The earthlings were given a choice - adapt to the new reality of Classes, Levels, and Trials... or die.  Alexei Zverev, a youth with intimidating looks but a kind heart, studied at Stanford to become a veterinarian. The System didn't ignore his (not always mutual) love for animals. Given the Tamer Class and the chance to take his three pets to the Tutorial, he entered the path to become the strongest Beastmaster ever alive. With Sasuke the Parrot, Mikasa the Dog, and Taiga the Cat, he will rise to the top in this brutal New World. When such reliable allies are by his side, even the Impossible Difficulty Trials don't seem so scary anymore!
