Chapter 3: Konoha Yellow Flash
Minato and Kushina were a couple from the time that he rescued her, and with his love, Kushina was able to keep the Nine-Tails sealed within her at bay. They eventually married. From observing a Tailed Beast Ball, Minato began a three-year process of creating the Rasengan, the height of shape transformation. He would spend the rest of his life trying to combine it with his own nature.
After proving himself an accomplished and responsible ninja, Minato was placed in charge of his own team, consisting of Rin Nohara, Obito Uchiha, and Kakashi Hatake. In the anime, the Third Hokage gave Minato the special task of helping Kakashi overcome the bitterness caused by his father's death and remind him of the human element of being a ninja. Minato gave his team a bell test upon its formation in order to teach them the value of teamwork. Minato often held back less against the prodigious Kakashi than with Rin and Obito so they couldn't obtain the bells without teamwork. Unfortunately, Kakashi realised this, but only used Obito and Rin as a means to an end to obtain the bells. Nonetheless, he passed them because they accomplished the goal of the test by working as a team. Although he did encourage them to improve their teamwork afterwards, a message that Obito and Rin took to heart, but fell on deaf ears with Kakashi.
When Konoha became involved in the Third Shinobi World War, Minato's obligations became split between training his students and helping with the war effort. During a mission into Kusagakure to destroy the Kannabi Bridge, Minato transferred leadership of the mission to Kakashi – who had recently become a jōnin – while he headed to the front lines. He met up with the surviving and out-numbered Konoha ninja and single-handedly wiped out the opposing Iwagakure forces. In the anime, his victory in this battle against a thousand ninja convinced the Third Tsuchikage to accept a peace treaty. When he rendezvoused with his team afterwards he found Kakashi and Rin and surrounded by Iwa-nin, Obito having already been lost. He rescued them, helped them complete their original mission once they recovered, and returned to Konoha with them to mourn Obito. Minato's competing obligations would later repeat the tragedy of Obito's death: while he was away on another mission, Rin was kidnapped by Kirigakure and died during Kakashi's attempt to retrieve her.
Minato encountered A of Kumogakure a number of times during the war.[18] During their first meeting, Minato and A fought with their speed, with Minato proving the faster. He received orders to retreat before their competition could resolve, but he lingered to compliment A and his brother, B, a jinchūriki like Kushina; he encouraged A to take care of B and remember he was a person. A pursued Minato, so Minato moved against B, threatening to kill him if A didn't let him and his team go. Minato was confident he and A would someday meet as Kage.
