Welcome to the Ballroom

Tatara is a third-year middle school student with no particular dreams his future, until He unexpectedly meets a professional dancer Sengoku.　Sengoku takes him to Ogasawara Dance Studio and introduces him to the world of ballroom dancing. Tatara is shocked to see his classmate Shizuku there.

Tatara begins taking dance lessons at Ogasawara Dance Studio, but progress is slow...At his first dance competition, he is overwhelmed by Shizuku and her partner Kiyoharu Hyodo's dynamic power.

Sengoku takes Tatara to the Prince Mikasa Cup competition, where he is both overwhelmed by Hyodo and Shizuku's performance and excited by this new world of dance. But then Hyodo disappears right before the second round of the Standard Division preliminaries...

Tatara steps onto the dance floor for the first time as a stand-in for Hyodo, who is nowhere to be found. Seeing Tatara and Shizuku on the floor galvanizes Hyodo into dancing the next number, in spite of Sengoku's efforts to stop him. While keeping his gaze on Tatara, Hyodo dances the tango with a new and intense passion.

Brother & sister duo Gaju and Mako Akagi appear at Ogasawara Dance Studio. Hyodo has been prohibited from competing, and Gaju takes the opportunity to ask Shizuku to partner with him. Shizuku agrees, and they start practicing together, leaving Tatara to pair up with Mako.

Gaju drops his sister/partner Mako to pair up with Shizuku, whose partner Hyodo is out of commission. Tatara partners with Mako and challenges Gaju, hoping to make him recognize Mako's talents and want her back as a partner. But when Tatara and Mako start practicing together, they run into some challenges of their own...
