Hirakawa Shin'un graduated from the Ninja Academy, formed Team 7 with Shiina Kō and Uchiha Yūichi, and traveled to the Land of Rain as war approached. After the team killed bandits on the road, Orochimaru tested Shin'un's combat instincts at the Konoha camp.
Shin'un refined Lightning Wall into Lightning Ring Wall, earned promotion after killing an Iwagakure Jonin, and led his squad through dangerous missions. The arc left him accompanying Hatake Sakumo’s team on a mission to extract Yakushi Nonō from Sunagakure, after they attacked a Sand Ninja outpost.
Shin'un helped Hatake Sakumo escort Yakushi Nonō out of Sunagakure pursuit, then returned to Konoha and learned of his Senju ancestry. As the war intensified, Hiruzen Sarutobi promoted Shin'un to elite jonin and ordered him to lead reinforcements toward Nara Shikahito, while Tsunade asked him to take Nawaki along.
Shin'un led Konoha forces against the Sand Ninja, then took a squad to steal intelligence from an outpost. The mission succeeded, but Dan Katō died from his wounds before Shin'un returned to camp.
Shin'un led Konoha forces back toward Orochimaru after Chiyo’s attack and faced Sunagakure’s giant puppets. He defeated a tiger-shaped puppet and uncovered the puppets’ optimal control positions before reaching Orochimaru’s camp.
Shin'un destroyed the Sand Ninja’s fortress puppet and helped release the One-Tail, then took command of Konoha’s forces as they moved to trap Sunagakure. The Sand Ninja launched a desperate breakout, leaving Orochimaru, White Fang, and the Third Kazekage caught inside a barrier.
Shin'un helped Konoha secure Sunagakure’s surrender and negotiate reparations, then discovered that the Giant Puppet Prototype came from another world. Back in Konoha, he joined the Anbu and became concerned about a strange airborne illness spreading through the village.
No recap yet. An arc gets one once it has 25 chapters.
