Tatara Fujita is a shy middle schooler who has no particular plan for the future. He has gotten through life by avoiding any kind of confrontation and blending in with the crowd. But blending in isn't enough to get out of trouble, as some bullies harass him for money. Luckily, he is saved by a man named Kaname Sengoku. Kaname invites Tatara to his dance studio. Although he would normally never set foot in such a place, Tatara is captivated by Sengoku's commanding presence. Granted an opportunity to dance with fellow classmate Shizuku Hanaoka—who often practices at the studio—Tatara realizes there's something about the idea of being put in the limelight and dancing where people will see him that keeps him coming back. With an earnest, passionate drive to improve, Tatara begins his journey into the world of competitive dance.

An innocent young man, Ikuroo, has a parasite known as Baoh implanted in his brain by an evil organization, Doress. The parasite makes him nearly immortal and gives him the ability to transform into a really powerful beastie when he's in trouble. Doress intends to use him in some sort of ploy for financial success, world domination, or something along those lines, but when they're transporting him on a train, a young psychic girl, Sumire (who's being held by the organization due to her abilities), sets him free and the two escape together. Of course, Dr. Kasuminome is the mad scientist behind the whole Baoh thing, and he isn't about to let his test subject get away and he has considerable resources (including some superpowered lackeys, as well as a small army) at his disposal.
