After hearing Madara Uchiha's words, Hayato Hyuga could not calm himself for a long time. The sheer shock he felt even temporarily eclipsed his grief over his teacher's death.
In Hayato's mind, however gifted Madara Uchiha might be, however much stronger he was, he was still a child younger than Hayato himself. Most of the time, Hayato still thought of Madara as a peer.
But today, as Hayato Hyuga looked up at Madara Uchiha standing above him, he finally understood. Though Madara Uchiha looked only eight years old, he was far more than an ordinary child his age. Perhaps even Kazuhiko, who had already become a Jōnin, could not fathom what went on in Madara Uchiha's mind.
"What do I get out of serving you? What's the difference between putting my life in your hands and putting it in the hands of the Hyuga Main Family?"
After a long silence, once Hayato Hyuga was certain Madara Uchiha was not joking, he hesitantly voiced his doubts.
"I swear on the name of the Uchiha Clan that I will get you justice for what happened today. As for Kumogakure, the list of ninja who came on this trip is recorded at Konoha's entrance registry. I've already obtained it from my father. Serve me, and once I've grown strong enough, I can take you into Kumogakure to demand justice for Hizashi Hyuga. If that's what you want, I won't spare a single person responsible for Hizashi's death today. As for the Hyuga Clan, both you and your teacher are victims of its main and branch family system. Serve me, and once I become Hokage, I will force the Hyuga Main Family to abolish the Caged Bird Seal. When that happens, I'm willing to help everyone in the Hyuga Branch Family remove it completely.
