Stardust/Synopsis

History
When he was younger, he was already called heartless, and in one of these events, he got angry and punched everyone who called him that. He is approached by a friend on a bridge, who asks him what happened and then says that, in order to be angry, he must have a heart, suggesting that David try to become the nicest person in the world, thus changing others' thoughts. David is left curious by the idea.

At some point of his life, he was chosen as England's Hero. He held many concerts for charity and founded Black Cross. About a year before Shy's debut, Stigma's first appearance was in England, which was already under Stardust's jurisdiction at the time. Using his friend as a catalyst, Stigma caused chaos and forced the Hero to cut his friend's finger off to stop him, taking the ring.

Synopsis
David is called to the Heroes Hideout, and he was recording a clip before that, having to decline an invitation from one of his colleagues due to his work as a Hero. He arrives late, but just in time to save Iko Koishikawa from tripping over her own feet, noting the good smell of the borscht that Uni-Lord had made. Since all are gathered, they sit down.

Uni-Lord explains to Stardust about Shy's encounter with Stigma in Japan and he is impressed that she was able to retrieve the entire ring. He tells Shy that the first time Stigma showed up was in England and that he had to cut his friend's finger off so he could stop wreaking havoc, surprising both Shy and Iko, whom he "congratulates" on having her finger intact. Stardust is soon reprimanded by Spirits for scaring them, but he is surprised that she is also including Shy, asking Uni-Lord why he was called there.

Uni-Lord asks Stardust to fight Shy and Spirits is immediately against, offering to fight her instead. The English Hero, however, soon points out that she would never go all out against Shy, and Uni-Lord agrees that Stardust, due to his personality, would be perfect to prepare Shy for future battles. Shy reassures Spirits for wanting to be stronger, but Stardust questions her if she was ready to give up her post as a Hero if she lost.

Shy responds that she was ready for it and, despite Spirits' protests, the group moves to a multipurpose room. Stardust, after making sure Spirits wouldn't interfere, reviews the rules with Shy, flipping a coin to get the fight started. As soon as it touches the ground, Shy lunges at Stardust, but she passes right past him without hitting him. Stardust taunts her, but no matter how hard she tried, she couldn't hit him. He hits her to demonstrate how to attack someone properly, and Shy screams in pain. Stardust comments that he does his best because he doesn't sympathize with others' pain, and that Shy's compassion makes her weak.

Shy is unable to hit him due to his power, Flow, which allows him to "control the battlefield". He hits her again, suggesting that she becomes angry with him and fights with him as if she would kill him, claiming he would kill her first if she didn't. Spirits tries to interfere in the fight, but is stopped by Stardust, who says he is used to the Russian Hero's hateful gaze. Stepping on Shy's head, Stardust suggests that she give up, but to what Shy says she can still fight, they continue until she is completely wounded, but since her form hasn't faded, she was still determined.

Even though Iko begs Shy to give up, she doesn't, stands up shakily and says she'll keep trying as long as there are people on her side, surprising as well as intriguing Stardust. Shy discovers her power and attacks him with a torrent of flames, Stardust dodges his head and then attacks her, proving that his power could dodge Shy's flames. He says she would be killed by another heartless man like him if she remained naive. When Shy denies that he is heartless, Stardust remembers a moment from his past, wondering why Shy's words had triggered that in him.

Intrigued by Shy's earnest gaze, she continues to try to hit him, while Stardust remains brooding over the unnerving feeling she aroused in him. In a slip of his, Shy manages to hit him lightly on the cheek and immediately untransforms. Stardust stops her from falling, Spirits and Iko immediately come to Teru's side and he tells the Russian Hero that even though she is very innocent and naive, maybe someday they will need someone as reckless as her. After asking them to congratulate Teru in his place and to take her to a doctor, Stardust leaves, telling himself that maybe he was a little naive.

After calling in Doktor Schwarz and Lady Black to take care of Teru, Stardust is smoking in the hallways of the base until he is approached by Spirits, who thanks him. He doesn't understand why, even questioning her about not being with Teru. Saying she was unnecessary since Iko was there, Spirits thanks Stardust for making Shy act so determined, but making it clear that she hates him. Stardust is mildly surprised, but claims to like Spirits and her blunt manner. Spirits is exasperated, and Stardust tries to run away from her.
