While unconscious, Katsuo entered a dreamlike palace armory where he found a colossal Susanoo statue and phantom divine artifacts. The statue’s taunts unleashed his dark desires, and he manifested a uniquely black, destructive Susanoo.

• A nearby girl had rescued the gravely wounded Katsuo, who remained unconscious for three days before stirring in his sleep.
• Katsuo wandered through darkness and entered a vast, glowing palace, where he studied a colossal complete-body Susanoo statue until he felt himself transform into one.
• Katsuo explored the armory and recognized the Yasakani no Magatama, Sasuke Uchiha’s bow and arrow, and the Totsuka-no-Tsurugi, but found that the artifacts were phantoms.
• Katsuo touched the statue and noticed a nick in its sword, then heard a mocking voice and sensed malice in the statue’s gaze.
• The voice taunted Katsuo, stirring his rage and desire to destroy everything until black flames formed a violent, unprecedented Susanoo around him.

Katsuo awakened the Mangekyō Sharingan and fought his way through a dreamlike palace filled with murderous divine artifacts. After manifesting the Complete Body Susanoo and destroying most of the weapons, he discovered that Susanoo could wield the surviving artifacts and seized the Yasakani no Magatama.

• Katsuo’s Mangekyō Sharingan awakened as he faced losing the bonds he had gained after rebirth.

• Katsuo grabbed the Yasakani no Magatama with Susanoo and looked greedily toward the remaining artifacts.

Katsuo watched the Sealing Gourd shatter and unleash the Kusanagi-no-Tsurugi, then seized the sword as the palace began collapsing. He used it to destroy most of the divine artifacts, but remained trapped beneath a dangerous vortex of black clouds.

• Katsuo saw the Sealing Gourd shatter and release a blinding mass of sword light that injured him and shook the palace.
• Katsuo charged through the sword light with Susanoo and grasped the Kusanagi-no-Tsurugi just before his hand was stripped to bone.
• Katsuo recognized the Kusanagi-no-Tsurugi and swung it to split a falling boulder and tear open the dark sky.
• Katsuo enlarged the sword to match Susanoo and slashed, destroying roughly ninety percent of the divine artifacts in the ensuing blast.
• Katsuo dodged falling stones and watched the swirling black clouds overhead, finding no way out of the collapsing hall.

Katsuo stopped the catastrophic upheaval in his strange dream by replacing the Susanoo and divine sword, then awoke from his coma with his Mangekyō Sharingan newly awakened. Severely injured and nearly out of Chakra, he began treating himself and left his money pouch for the girl who had saved him before passing out again.

• Katsuo placed his Susanoo on the altar and used Kusanagi-no-Tsurugi to replace Totsuka-no-Tsurugi, then commanded the black mist and the chaotic sky to return to their former state.
• Katsuo awoke from his coma and discovered that his body was almost paralyzed, though some Chakra and ocular power remained.
• Katsuo activated his Mangekyō Sharingan and summoned a skeletal Susanoo arm surrounded by sinister Black Flame, but stopped when the little girl shivered beside him.
• Katsuo used the Susanoo claw to cut away his bandages, frightening the girl into fainting, then began treating his severe injuries with the Mystical Palm Technique.
• After his Chakra and strength ran low, Katsuo unsealed his money pouch for the girl to find, hoping she would buy medicine and nutritious food, and then fainted.

Uchiha Sheng’s force confronted Hanzo, who revealed that Katsuo had fallen in battle. As Uchiha Sheng grieved over Katsuo’s battered blade and suspected he had died pursuing the Mangekyō Sharingan, his eyes evolved.

• Hanzo halted the Rain Ninja’s advance, ordered them to withdraw behind him, and prepared them to face Uchiha Sheng’s force.

• Uchiha Sheng was devastated by the news and wondered whether Katsuo had died trying to awaken the Mangekyō Sharingan.
• Uchiha Sheng demanded to know who had told Katsuo about the forbidden power, and a jonin announced that his eyes had evolved.

After learning that Katsuo had died, Uchiha Sheng awakened his Three-Tomoe Sharingan and attacked Hanzo the Salamander in a rage. As Hanzo’s poisonous mist closed in, the Uchiha fought back against the Rain ninja, leaving Hanzo’s forces in retreat.

• Uchiha Sheng mourned Katsuo’s death, blamed himself for keeping the Mangekyo secret, and awakened his Three-Tomoe Sharingan.
• Hanzo the Salamander told Uchiha Sheng that Ibuse had swallowed Katsuo, then taunted him as the Rain ninja laughed.
• Uchiha Sheng charged Hanzo, but Hanzo blocked his strike and fought defensively while waiting for Ibuse’s poisonous mist to spread.
• An Elite Jonin ordered the Uchiha jonin to use Wind Release against the mist and the rest of the clan to use Fire Release against the Rain ninja.
• The Uchiha combined Wind and Fire Release to push back the poisonous mist, then charged through the smoke and drove the Rain ninja into retreat.

Hanzo the Salamander unleashed poison mist and summoned beasts against the Uchiha Clan, but their combined Fire and Wind Release briefly pushed back the poison and turned the battle in their favor. Black and White Zetsu watched as the poison mist returned, Hanzo killed a Uchiha jonin, and Uchiha Sheng ordered a retreat just as Hanzo prepared to finish the clan force.

• Uchiha Masawa’s Phoenix Sage Fire and kunai slowed Hanzo, allowing Uchiha Ichiya to strike him with Lightning Panther and Exploding Tags.
• Hanzo survived with a charred, bleeding arm, but the Uchiha escaped and he admitted that he had underestimated the clan.

After recovering from his wounds, Katsuo invited Konan to leave the cave with him, and she accepted despite fearing she would burden him. As they traveled together, Katsuo sensed an approaching ninja unit, and a ninja confronted them.

• Katsuo used Susanoo to block weapons and kill or disable several Cloud Shinobi despite their attacks.
• Katsuo expanded Susanoo into its Mature form, and the remaining Cloud Shinobi jonin ordered his men to carry their unconscious comrades and run.

Katsuo used Susanoo to annihilate a group of Cloud Shinobi who tried to flee, then took Konan safely back to Konoha's command headquarters. On the journey, he considered the severe cost of his Mangekyō Sharingan's power and the terrifying attack sealed in his right eye.

• Katsuo summoned Susanoo's Kusanagi Blade and cut down the fleeing Cloud Shinobi, leaving one unconscious Chunin behind.
• Katsuo dismissed Susanoo and left the battlefield with Konan, who later opened her eyes and praised him for being a powerful ninja.
• Katsuo used Genjutsu to handle further trouble on the journey and reflected on how Mangekyō Sharingan power gradually drained away.
• Katsuo realized his right-eye technique concentrated most of that eye's power and would nearly ruin it if he used the attack.
• Katsuo and Konan returned to Konoha's command headquarters after encountering resistance along the way.

Katsuo returned to the Uchiha camp with white hair and a failing body, and Tsunade secretly learned that he had less than two years to live. As Uchiha Sheng prepared to send him back to the village, Katsuo asked to break out with the others, and his next move left Sheng stunned.

• Uchiha Sheng welcomed Katsuo and fetched Tsunade to examine him.

After driving back the demigod, Katsuo discussed Mount Myōboku’s Sage Spring with Orochimaru and revealed that the Mangekyō Sharingan and his prodigious strength were consuming his life. He planned a desperate attempt to reach the spring with Orochimaru in three days.
