Nobody's point of view:
Madara continued smiling at the dragon and the dragon suddenly lowered to the floor and Madara quickly made a portal teleporting in front of him and looked at him with a half smile.
""I really haven't seen anyone use such an exceptional ability." The dragon was more than surprised and really thought that Madara was someone he had never seen before. "Well actually I got this skill from a book." Madara said with a shrug and the dragon was surprised by the content of that book.
"What is that book? If I could know? The dragon wanted to know more about the abilities that book had since that ability could see that it did not use chakra, but other energy. Madara didn't really care to tell him since the summoning beast really doubted he would tell him anything else. She just took the book out of nowhere, surprising the dragon again, but the truth is Madara only took it out of the system's inventory.
"That one." Madara gave her a large book and what she saw of the dragon also surprised her. This invocation was wonderful. He became small, almost the size of her but a little bigger, she took the book and when she leafed through its contents she was surprised. " Does this book really exist? Can I say that it is not chakra but another energy, like natural energy?" The dragon hesitated a little and Madara previously thought the same. "Yes, it is similar to natural energy." But However, it is something different if it is not the energy of this vast universe. Madara would say, remembering a little and thinking a little. The dragon understood and continued reading the book, intrigued by this girl, he saw enough and spoke.
"I see the unlimited potential you have, as a dragon we have the power to see through the soul and of course read the approximate future." Said the dragon who for now did not know its name and Madara was surprised by that information. "I see, no. We have introduced ourselves properly, I am Madara Uchiha." Madara bowed gently, doing so for the first time. She respected power and this dragon with its presence showed it and therefore I respect it. The dragon just smiled arrogantly and said with a deep voice. "I am Ryunosuke, the leader of the Dragon Clan, and I accepted you as my summoner after thousands of years of not accepting one." Madara found that curious. "Why hadn't they accepted a summoner?"
"The dragon clan is a Noble and powerful clan, we will not accept mediocre summoners, since the creation of the dragon clan we have only accepted one Summoner and that was one of the children of the six paths... Indra otsutsuki." What Ryunosuke told him surprised greatly to Madara, was his ancestor really the first summoner?! Now he knew why this dragon accepted him, comparing the abilities that the dragon clan has, he saw something of Indra in her so he just nodded, he didn't feel special about it. absolute only the whole dragon because of its strength, really in this world personal relationships can weaken or strengthen of course she did not have the same ideology as the original Madara of doing everything by himself. She took what she could from people to be useful and saw his worth and this dragon had it and he just nodded.
"Does that mean that you will accept me as your summoner?" Madara spoke, smiling a little at the fact he recognized. Ryunosuke just nodded and a scroll appeared in front of them. "You just have to sign this contract with your name and your blood." The dragon He spoke and Madara nodded, with a kunai that he kept before he cut his finger and wrote his name with his crimson blood, I could see above the name of his ancestor, a really elegant letter and she only felt excited a little, he really sealed the deal with the dragon clan...
