To get the now-childlike Mona onto their team officially, G-Wrench and the team visit league registration. It's revealed that Mona can use a Fight Burst, but doesn't remember how to do it. As Kara's suspicions grow, Professor Pi's team Q.E.D. challenges them to a match.
Let's throw down, me and you!
!لنفعلها بملء طاقتنا، أنا وأنتِ
Stell dich mir, nur wir zwei!
¡Enfrentémonos, tú y yo!
¡Enfrentémonos!
Je t’attends pour un duel !
Sfidiamoci seriamente faccia a faccia!
Vamos nos enfrentar a sério!
Выходи и сразимся, только ты и я!
