Let's... Keep Flying!! - S1.E12

Asuka is facing off with Saki. Asuka uses three consecutive Sonic Boosts and a new technique called Pentagram Force to score the first two points. After scoring a point herself, Saki attacks Asuka but the latter evades all her attacks and scores her third point. Now 3-1, an angry Irina orders Saki to switch off her balancer, allowing her to tap into the full potential of her shoes.
