Vampires have existed for centuries and live under the rule of the Scarlet Moon. Once a year, "Visual Prison" occurs, a visual kei competition where the vampire who sings the most beautiful song is bestowed with great power by the Scarlet Moon. At the forefront of the competition are ECLIPSE—the reigning champions who stand for an established order, and LOST EDEN—a group that believes the strongest should rule. Ange Yuki is a lonely boy with no confidence in his singing ability. He moves to Harajuku in search of a musician he idolizes, but during his quest, he gets entangled in one of the many live performance clashes between ECLIPSE and LOST EDEN. Their fascinating stages stun him, but he soon collapses, overcome by bloodlust. Regaining consciousness, Ange finds himself under the care of Guiltia "Guil" Brion, the musician he admires, and learns that he is a dhampir—half-human, half-vampire. While Ange now has the privilege of participating in the upcoming Visual Prison, Guil explains that he will not join him in this endeavor. Meanwhile, Ange encounters Robin Laffite, a foreigner from England who is enamored by his astonishing singing voice. With the day of the competition slowly creeping up, Ange has to put together a capable unit in an exciting race against time.

Due to rising sea levels and a rapidly declining human population, androids have been engineered to perform most menial tasks, allowing humans to focus on other things. Aside from providing manual labor and customer service, androids also entertain humans through Babel—a tower where participants captivate audiences with song and dance to clear Climb Stages. The higher the climb, the more prize money is awarded. Androids Cobalt, Chrom, Neon, and Kei are down on their luck and about to have their electricity cut off from unpaid bills. Desperate to make a quick buck, the group decide to become Babel climbers. However, winning the audience's favor is a great challenge. Dejected but unwilling to give up, Cobalt resolves to somehow improve their chances after watching an impressive performance by STAND-ALONE—the top climber unit. When the group stumbles across a mysterious choreographer willing to give away his routine, Cobalt sees this as their only way up. With the help of their human companion, Esora Shibaura, the androids form the unit KNoCC to tackle the daunting climb to the top of Babel, but they must also overcome android-based discrimination along the way.
