[A battle had broken out in the beach along with an argument between Kanade and Souta. While Hibiki engaged the Negatone who had been made from the box of cupcakes that Souta had made, Hibiki grit her teeth and pushed the Negatone back. Kanade had lost a lot of her power, due to the conflict in her heart as her Harmony Power had been severely disrupted.
With several blows from a powerless Rhythm, it seemed hopeless for her to achieve victory. Seiren looked pretty smug from her end.]
Seiren: It's hopeless for you, why don't you give it up?
Kanade: I'm the older sister. I cannot leave my precious brother behind even if I lost my powers!
Seiren: Enough acting tough. Negatone, go!
[With the Negatone charging for Rhythm, Melody jumped in front as she clashed with the Negatone.]
Hibiki: My pride rides on defeating this!
[As Hibiki fought, Rhythm charged into the glowing mess as she stretched out her hand.]
Rhythm: Give me your hand!
Souta: Sis doesn't care about me! I hate her!
Rhythm: That's not true! Your sister cares about you!
Souta: No matter what I do, she gets mad at me! What should I do?!
Rhythm: If she doesn't care for you, she won't get mad! It's because she cares for you that she gets mad!
Souta: It's because she cares?
Rhythm: People who don't care won't get mad. Your sister cares for you.
Souta: But she'll get mad at me. We fight all the time.
Rhythm: You just have to make up with her. Like always, right? Here, give me your hand. [She stretches her hand out to him.] Let's go home to where your sister is.
[And with that, Rhythm pulled him out of despair. However, the Negatone launched an attack at them seconds afterwards. With the tender moment almost cut short via cupcake bombs, Melody leaped into the fray again, kicking and punching the explosives to the sides.]
Melody: I won't let you hurt Rhythm and her brother! They are awesome! They always fight with each other, but protect each other when it counts, like it's the most natural thing in the world.
Seiren: So what? You're not related, right?
Melody: That's right. I'm an only child. I don't have anyone like that.
Seiren: Then just leave them alone. You have nothing to do with them.
Melody: That's right, but I don't want them to feel lonely. They are precious to me, so I want them to be like me and Rhythm, always fighting and always making up. Their feelings... Their connecting hearts... I'll protect them all!
[What happened next? Pure and astute asskicking.]((Joint canon update for Kanade and Hibiki (wildmelody); replies will come from both girls, a little while after the battle.))
