Arc 10The Fourth Shinobi World War
Issui led the Allied Shinobi Forces against Obito and Kabuto, overcame the revived Kage, and survived Kabuto’s attempt to steal his soul. After uniting the shinobi and helping Obito turn against Madara, Issui faced Madara alone, with his final battlefield-wide frost attack still unfolding.
- Obito declared war after revealing his Eye of the Moon Plan, and Issui uncovered White Zetsu spies at the Kage summit.
- Issui helped Tsunade organize Konoha’s forces and joined the Allied Shinobi Forces as supreme deputy commander, while Obito prepared nearly a hundred thousand White Zetsu.
- Kabuto lured Issui into a trap and used Sage Art: White Rage Technique and the Eye of Heaven’s frost to freeze his soul, but Leins carried him back to camp and Hinata’s tears revived him.
- Issui merged his soul with Yi Shui, gained the Wind Heaven Eye, and returned to lead the Allied Shinobi Forces against the White Zetsu army and Obito.
- Issui destroyed the White Zetsu army and defeated Obito’s assault, then revealed that Rin was alive and helped Obito reunite with Rin and Kakashi.
- Madara arrived and urged Obito to join his plan, but Obito rejected him, and Issui stepped forward to face Madara as the Allied Shinobi Forces rallied behind him.
- Issui countered Madara’s fire techniques with water and ice, then used an ice-crystal cherry tree to repel Madara’s attacks and break apart two summoned meteors.
- Issui’s Hornless Dragon failed to stop Madara, so Issui unleashed a battlefield-wide frost technique that froze souls and forced the allied fighters to retreat.
