Gem of Heart
In the first chapter, Rei and Ichiro are shown to fall in front of a girl. The two start bickering when a seahorse appeared and told them to stop creating a scene. The two are puzzled and the girl clears her throat. The two noticed her but before they could proceed a bunch of students attacked them, prompting the duo to cast a shield. The moment they let it down, however, they are attacked once more; and this time, they flee. When they reach an alleyway, the girl punches him sending him to land on the ground on his head and the two start bickering. When the man told them that the medicine would take till Christmas, the boy is mortified.

Their conversation was soon interrupted by two people. The duo are forced to then fight with Hifumi and Shiro. After the fight, Noa has a vision and they go to a Music School, where Noa is known. As they entered, he and Ichiro are surrounded by girls as Noa talks to one of the students. Rei notices her and tries to get out of the crowd but to no avail.

When the girl played her guitar, the two boys had pushed their way through the crowd. On their way back, Rei asked Noa how she knew what to do, to which the red haired responded that she was experienced. As they talked, a Prime Stone appeared in front of them. Before he could take it, however, Team Ultra took it. Soon a fight broke out. However, the Shiro he was fighting with was a clone as the real one kidnapped Noa.

He is then shown sitting on the back seat of the car complaining about how the duo had gotten tricked. Rei is soon able to find out the location of Noa and attacks the opposing team. He and Ichiro had casted a shield to protect Noa while injuring themselves and ignoring the please of the girl as Zuka explained to her. The blunette had shuddered at the mention at the mention of their parent's, grandparents, aunts, uncles and siblings scolding and stories, showing that he might dread hearing them so many times. After they let down the shield, Rei attacked Team Ultra with 'Destruction Magic, Broken Storm'.

After the fight, the two are thanked by Noa. When the girl blushes, Rei comments how she had caused them so much trouble, Noa hit him with a hammer (which she brought out of mid air). When Noa says that it would've been much worse if she had her whip, he comments how the hammer hit hadn't hurt (which was a lie), Noa hit him more times while calling him an idiot and Ichiro and Zuka watched the scene motionlessly.

Quotes
