As Shinra questions what Adora Burst is, Rekka tells him it is the thing that he and others are looking for under his leader's guidance. He goes on to say that he planted the sparks within children to find a compatible person, to which Shinra becomes enraged and begins his attack. Rekka ridicules Shinra for being so easily agitated, and fiercely punches him, to which he accidentally lands into Tamaki's cleavage. As she pushes him away, Shinra is attacked by a flurry of flaming punches that eventually reach Tamaki, burning all her clothes, leaving her in just a bikini and bra. Shinra looks at her dazzled, but falls victim to Rekka's punch again, and ends up all over Tamaki seductively. As she pushes him away again, encouraging him to fight, she grips onto his back, begging him to defeat Rekka. Now determined, Shinra walks toward him confidently. Taking a minute to think about the situation, he realises that the best way to defeat him is to use his greater mobility in the surrounding area. Rekka burns his sleeves and prepares to go all out. The two clash, fist versus leg. Shinra uses his flying ability to dash to a wall, and, as Rekka prepares to punch him, he quickly moves closer to the Company Commander before the latter can react, and explosively kicks him upwards. Rekka continues to punch him, but Shinra manages to dodge all of the attacks. As he prepares for his final attack, Shinra lands onto the ceiling and jumps off rapidly, falling into the opponent at incredible speed with a fiery kick and landing a direct critical hit straight into Rekka's face.
