Kiss Me if You Can - Chapter 4Vol 1.

In a world without gods, where the laws of magic are written by the mages themselves, balance is fragile, and darkness reigns. Multiple dimensions surround it, watched by beings with dark and greedy intentions. This is a magical universe, unstable, marked by constant changes, betrayals, and bloodshed. At the center of it all, an ordinary man emerges, carrying a biochip capable of deep analysis and data recording.

Here, the only rule is to conquer or be consumed. A dark fantasy filled with dangers, evolution, and the relentless pursuit of supremacy.
