In a realm where humanity's history has been eclipsed by the rule of the Ikars, a game of twisted amusement holds the key to both their entertainment and the fate of mankind. Forgotten are the painful origins of their subjugation, as the humans now revere their captors in the midst of this dark and elaborate game. Known as the Enigma Tower, this ominous structure beckons participants from every corner of the universe. With its towering presence and 99 treacherous floors, it promises the ultimate glory to the one who conquers its heights. Each floor teems with creatures and challenges, a relentless ascent that only the most determined dare undertake. Among those braving the tower's perils is Kieran Vale, a prince hailing from the desolate planet of Zeroes. As he battles for survival, his companions fall one by one, leaving him to face the tower's horrors alone. Yet even as victory seems within his grasp, Kieran meets his untimely end at the hands of fellow humans. But death is not the end. Awakening in a body not his own, Kieran's consciousness is trapped in an unfamiliar vessel. Fueled by an unquenchable thirst for revenge against those who betrayed him in the tower, Kieran now harbors a consuming desire: to unravel the mysteries of the Ikars, expose their malevolent intentions, and finally break free from the shackles that bind humanity. In a world where the line between reality and illusion blurs, Kieran's quest for retribution becomes a battle not just for his own salvation, but for the very soul of mankind itself.
