There is a tower that summons people called “Regulars” with the promise of granting their deepest desires. Whether it’s wealth, fame, authority, or something that surpasses all of them everything awaits those that reach the highest .
Twenty-Fifth Bam may be a boy who had only known a dark cave, a unclean cloth, and an unreachable light his entire life. So when a woman named Rachel came to him through the sunshine , his entire world changed. Becoming close friends with Rachel, he learned various things about the surface world from her. But when Rachel says she must leave him to climb the Tower, his world shatters around him. Vowing to follow after her regardless of what it takes, he sets his sight on the tower, and a miracle occurs.
Thus begins the journey of Bam, a young boy who wasn’t chosen by the Tower but opened its gates by himself. They call his kind “Irregulars” beings that have shaken the very foundation of the Tower whenever they set foot inside it.
