Arc 1The Rōran Reinforcement Mission
Baiye rose to Chunin, saved Minato and Kushina from the Nine-Tails, and prepared for the coming war while strengthening his Shinigami and ninja abilities. After learning that Minato’s team had gone to Rōran, Baiye joined a reinforcement squad and left Hayate to train until his return.
- Byakuya awakened in the Naruto world with a deadly Gekko clan bloodline disease, received a Zanpakuto and access to Shin'ō Academy, and began learning from Aizen.
- Baiye trained in Kidō, swordsmanship, and ninja techniques, defeated Kakashi in a spar, and treated Hatake Sakumo after Sakumo attempted suicide amid rumors about his mission.
- Baiye helped Sakumo survive and step away from shinobi life, earned Tsunade's trust, and became a Chunin after passing his assessment.
- Baiye intervened when the Nine-Tails ran wild, healed Minato, helped Kushina restrain the beast, and later spoke privately with Minato and the Nine-Tails.
- Baiye opened the Gate of Opening with Might Guy's guidance, while Minato recovered and gave him a Sealing Jutsu scroll and the name Rasengan for his new technique.
- Hayate graduated from the Ninja Academy, and Baiye subdued an Uchiha Chunin who attacked him before encouraging Hayate to train and surpass Shisui.
- Shikaku told Baiye that Rōran's former queen had died and that Minato's team had gone there, so Baiye volunteered to reinforce them and seek a chance to meet Shukaku.
- The Third approved Baiye's mission and Shikaku assigned him to Tsume Inuzuka's five-person squad, which planned to depart the next morning.
