Arc 4The Divine Son’s Campaign

- Issui reunited with Hinata, but his affairs with Fini, Mei Terumi, and Kazahana Koyuki led to a confrontation in which he stabbed himself and Hinata awakened the Mangekyō Byakuringan to reach him.
- Hinata forgave Issui under strict rules and asked Haku to become his woman, and the three agreed to form a family despite ongoing clashes with Fini.
- During a mission with Shizune and Haku, Issui fought and killed Kimimaro, then helped pursue Sasuke with Naruto’s team before letting Sasuke leave with information about Itachi.
- Issui found the Phantom Underground Ruins, absorbed the Gelel Vein, and unlocked the fourth stage of his Eye of Heaven, which revealed a coming threat from another world.
- After receiving Tsunade’s approval for an extended mission, Issui left Konoha with Haku, told her about the approaching demonic beasts, and made her his wife and assistant.
- Issui and Haku entered the other world, where Issui rescued Bruton’s villagers and was welcomed as the divine descendant of Auguste Philia.
- Issui introduced ninja cultivation to the rulers of the three kingdoms and proposed defeating the magical beasts’ leaders and allying with the elves and dwarves.
- With Xiliya’s guidance, Issui went alone to confront the Two-Headed Frost Wolf Xiaotian, but Xiaotian survived his black flames and froze him with Extreme Ice Feast.
