After seeing how their parents died to Fidro the brothers became sad and started training so that they get stronger and defend them selves because the brothers lived in a though village with grandma. She had a secret training room where no sound can be heard from there no matter how strong the blows are. Akito beeing the big brother had to look out for his brothers. And he is responsable for their training. So Buchuro the strongest of the two younger than him so he was up first against Akito. Akito couldin't go full power cause Kurama the Nine Tail told Akito not too. So he listend.
Buchuros phoinex aura felt similar to Fidros phoinex so Akito stopped the fight and let Juhwan go up against him. Juhwans Dragon had impressive powes like Dragon claw, Blast breath and Fire shower. Akito used Soaring Beast and an aura of the nine tails blasted sound waves that made anyone passout. Juhwan was put to sleep after. Naotos Ice dragon was pretty though for Akito when he is not using full power against him. Naoto used Ice breath and Ice sword which was kind of strong for a 14 year old like Naoto. But Akito counterd the attacks and summoned Kurama and used a form called Yokai. This form is used when the user is draining energy from the opponent and charges a powerfull blast of energy. And Kurama changed color to yellow black like it has awakend. Good thing enough Akito and Kurama didin't fire their strongest one but a strong blow that Naoto got damaged pretty much of.
