Raised by an abusive father, bullied by his tyrant classmate, and grew up without a mother and friends, Kaiju was chosen by the Tower as a player to participate in the trial. However, how could the Tower blundered about overchoosing its participants? Kaiju didn't have a choice but to participate on the Hellish Trial, the difficult there is. Without much preparations, Kaiju had to rely on luck to survive. [You have survived through a fortuitous encounter. You have obtained 10 Luck Points! Your 10 Luck Points are multiplied ten times… Congratulations! You have been rewarded with 100 Luck Points!] When Ladyluck decided to help him, can he survive the Hellish Trial and possibly completed it, when, in the history of the Tower, no one haven't yet? [You have formed a master and pet bond with the Savage Beast. You have obtained the title, Beastmaster!] With the beasts accompanying him, will he soar and conquer the Tower?
