Arc 1The Eye of Heaven Awakens
Issui Kanna survived the destruction of Heaven Village, grew stronger in Konoha, and discovered the Eye of Heaven’s power through battles with Kakuzu and Root. After recovering from a devastating attack, he advanced in rank and prepared to help Hinata develop her Ninjutsu.
- Zabuza Momochi attacked Heaven Village, and Issui escaped to Konoha after awakening the Eye of Heaven and sealing Zabuza’s Ninjutsu.
- The Third Hokage approved Issui’s engagement to Hinata, and the two became close as Issui trained and befriended Naruto and Sasuke.
- Issui captured the missing-nin Nanaha, passed an early graduation test, and became a Genin despite Danzo’s interest in his bloodline.
- Issui escorted Yamada Hika’s caravan, killed the bandits who attacked it, and then fought Kakuzu, awakening the Eye of Heaven’s second stage before Jiraiya rescued him.
- Issui returned to Heaven Village, honored its dead, found its secret scrolls, and summoned the fire dragon Laxus as his ninja beast.
- Five unidentified ninja ambushed Issui near Konoha, and he unleashed Magma Hell before Kakashi and Might Guy found him unconscious.
- The Third stripped Danzo of control over the Anbu, and Issui recovered, became a Chunin and then a Special Jōnin, and refused an Anbu position.
- Issui planned to remove the restriction preventing Hinata from using advanced Ninjutsu, with Hiashi preparing four trusted Jonin to maintain a barrier.
