A Heartless Person Shy begins her training fight with Stardust, where the goal is to land one punch on his face. Every effort proves fruitless as Stardust shows the ability of his power: to control what flows around him, causing Shy's punches to miss. He shows no hesitation in attacking Shy with brute and powerful force, as he lacks empathy for others' pain; he suggests Shy to act the same in order to fight effectively as a hero. It is in the midst of her fight that Shy realizes the power of her Heart-Shift Bracelets: the ability to conjure flames. As Shy realizes why Stardust is being so rough with her, she is able to land one small strike on Stardust's cheek with the last bit of her stamina, as Stardust momentarily let his guard down, thereby conceding the fight to her and allowing her to continue being a hero. While recuperating in the infirmary, Teru meets two more heroes: Switzerland's hero, Lady Black (Piltz Dunant) and Germany's hero, Doctor Schwartz (Gelm Stein) from the international rescue organization Black Cross. Afterwards, while walking home together, Teru vows to be a stronger hero so Iko will never have to cry for her again.
