There is a tower that summons chosen people called Regulars with the promise of granting their deepest desires. Whether it be wealth, fame, authority, or something that surpasses them all—everything awaits those who reach the top. Twenty-Fifth Bam is a boy who had only known a dark cave, a dirty cloth, and an unreachable light his entire life. So when a girl named Rachel came to him through the light, his entire world changed. Becoming close friends with Rachel, he learned various things about the outside 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 no matter what it takes, he sets his sight on the tower, and a miracle occurs. Thus begins the journey of Bam, a young boy who was not 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 each time they set foot inside it.

God has abandoned the world. As a result, life cannot end nor can new life be born, and the dead walk restlessly among the living. Granting one last miracle before turning away forever, God created gravekeepers, mystical beings capable of putting the dead to rest through a proper burial. Ai, a cheerful but naïve young girl, serves as her village's gravekeeper in place of her late mother. One day, a man known as Hampnie Hambart, who is supposedly Ai's father, arrives and kills all the people in her village. Having lost her village and with no plans for the future, Ai decides to accompany the mysterious man on his journey. As she travels the land, the young gravekeeper strives to fulfill her duties, granting peace to the dead and assisting the living, while at the same time learning more about the world that God left in this tragic state.
