In the near-future, Tokyo is ruled by a wizard. Rei is an odd-job maintenance worker who lives in Twilight Town, one of Tokyo’s impoverished slums. One day, he meets Guan, an incredibly attractive man. Guan is covered in tattoos, and carries himself with the arrogance of a highborn. Their meeting leads to a night together… and becomes pivotal for the future of Tokyo. A fantastic, magical love story about overcoming fate told through the experiences of an obstinate handyman and a charismatic leader.
