Crimson Tower

Daimon Crimson, a vampire who had lived for centuries in a modern world where vampires were considered legends, found himself bored to death with nothing to challenge him, despite his eternal life. As the strongest vampire, no one could match him in combat, leaving him unfulfilled until a momentous day arrived. World Towers suddenly materialized all over the world, interconnected structures that had to be conquered to save the world from destruction. Upon entering one of these towers and facing the monsters within, Daimon experienced an unparalleled thrill. He was ecstatic to discover that the monsters were remarkably powerful, finally providing the excitement he had been yearning for all this time.
