Might Guy trained under Might Duy, entered the Ninja Academy, and helped Hatake Sakumo through a crisis before war threatened the village. As the story left off, Duy had taught Guy the first three of the Eight Inner Gates, and Guy was preparing to grow stronger for the coming battles.
Might Guy advanced from Academy missions to the war front, becoming a Genin and then a Chunin while protecting his teammates and defeating Iwagakure shinobi. The arc ended with Guy and Team 9 stationed on a ridge, preparing to face an advancing force of two thousand enemy soldiers.
Guy warned Konoha that Sunagakure was preparing to attack, but Sarutobi Sosuke punished him for sounding the alarm. When the assault came, Choza took command and Guy helped turn the battle against Rasa’s forces, ending the stretch as he struck at Pakura with his newly forged Du'e Blade.
After helping Konoha win at Kikyo Mountain, Guy returned home, supported war orphans, and was assigned to the Land of Waves front. There, Team Nine’s reconnaissance mission turned into an ambush, leaving Guy facing Mei Terumi while his teammates fought Hozuki Mangetsu and Hyuga Yuma struggled against Ao.
Guy and Team 9 defeated Kirigakure’s forces at Reef Bay, then escorted Hozuki Mangetsu to Orochimaru’s camp. Their next assignment brought them to an all-Uchiha outpost commanded by Uchiha Hisui, where they met his young son, Uchiha Shisui.
Guy, Ebisu, and Genma helped the Uchiha defeat Roshi at Outpost Eight, triggering a dangerous confrontation with Iwagakure and reshaping the frontline. After being transferred for their safety, they reunited with Kurenai and Asuma just before a large-scale enemy attack began.
Konoha defeated Ōnoki’s Iwagakure force, and Guy helped save White Fang and the endangered shinobi before joining reinforcements in the Land of Grass. There, Guy helped Obito awaken his Sharingan and began a clash with Kakashi that revealed his growing strength.
Guy sparred with Minato, then transferred with Ebisu and Genma to the Land of Rivers, where they encountered Pakura and the Seven Ninja Swordsmen. After committing to fight them, Guy killed Hozuki Kurisu with the Sixth Gate, and Pakura took the Spinach Pill.
Guy and Pakura fought the Seven Ninja Swordsmen, then Guy spared Pakura and met Yahiko’s Akatsuki. After returning to Konoha, Guy broke through the Yijin Jing, earned a jonin promotion, and began training with Chen to refine his taijutsu.
Guy completed Teacher Chen’s demanding training and joined Ebisu and Genma in the Giant Forest to secure a summoning contract. After gaining the Crab Fortress King as their summon, the team set out to find a reconnaissance beast and approached a cave of genjutsu-producing bats.
Guy’s team found and rescued Anko from Amachi’s underwater experiment base, then brought her to Orochimaru before escorting her toward Konoha for treatment. The arc ended with Shizune leading them to meet Tsunade.
Guy trained under Tsunade in medical ninjutsu, chose the Yin Seal, and learned Creation Rebirth as his return to the battlefield approached. He prepared to deploy near Kannabi Bridge with Ebisu and Genma, then went to inspect the Ninja Tortoises and recognized the caretaker.
Guy formed contracts with the Ninja Turtle Clan and Katsuyu, treated White Brow, and helped Tsunade overcome her hemophobia. He arranged a turtle-jelly business to support the orphanage and turtles, then left Konoha for Kannabi Bridge, where he learned the Uchiha stationed in the Land of Rice Fields had been wiped out.
Guy destroyed Kannabi Bridge, fought Yugito Nii, and learned that Rin had been captured while Obito might still be alive. He and Kakashi reached Rin on Sentry Island, but Kirigakure’s forces surrounded them as a familiar leader arrived.
Guy, Kakashi, and Obito subdued the Three-Tails and rescued Rin, while Obito survived and returned to Konoha after losing his memories of the black-robed figures. After reporting to the Hokage and tending to their wounds, Guy brought Obito and Rin to Minato, who reinforced Obito’s seal and began examining Rin’s.
Guy helped secure peace between Konoha, Iwagakure, and Kumogakure, then took in war refugees and helped establish their care at Konoha’s orphanage. As he recovered from his fight with A and prepared to cultivate the Yin Seal, Kakashi told him that White Fang might be nominated for Hokage.
Guy helped Jiraiya save Yahiko, Nagato, and Konan, then killed Hanzo and was sent to the Fire Temple to ease the political fallout. There, as Fahai, he mastered the temple’s chanting and manifested powerful forms of Sage Clan Talent.
Guy became head of the Fire Temple’s Martial Monk Hall and taught its monks four Shaolin arts. When Itachi visited, Guy’s conflicting compassion and killing intent awakened the Du'e Blade, leaving Itachi unharmed and the temple bathed in golden light.
Guy prepared for the Nine-Tails’ attack, saved Might Duy by making him the Four-Tails’ jinchuriki, and helped Minato and Kushina seal the Nine-Tails inside Naruto. After the attack, Guy took Naruto to the orphanage and learned that the Uchiha Clan had defected from Konoha.
Guy left Konoha on a secret mission, rescued several children from dangerous fates, and found a lucrative way to support the orphanage. After taking Kimimaro and Haku from their homes, he became trapped in a confrontation with Kirigakure and discovered that Yagura was the Six-Tails Jinchuriki.
