Let's Dance a Waltz Vol 2

From the Kodansha edition

It’s time for the competition to begin! Yūsei and Himé have a special routine prepared, designed to bring Tango back to the world of Dancesport. Can the two of them reignite the passion Tango once had for ballroom dance, or will Himé fail to stoke the flames of Tango’s competitive fire?
