History

Early life and Konoha Academy

Su Yu returned to Konoha Ninja Academy after a month away following his parents’ deaths. A transmigrator focused on becoming stronger, he completed ten system achievements and used the resulting draws to obtain Genin-level chakra, Uzumaki and Uchiha bloodlines, and several foundational techniques. His first system mission required him to become a Konoha Genin within one month or defect from the village. 1

Seeking faster growth than Konoha could offer, Su Yu approached Yakushi Kabuto and declared his intention to follow Orochimaru. Kabuto agreed to keep him undercover in Konoha until he was stronger, supplying taijutsu and Eight Inner Gates training methods. 2

After passing the Genin examination, Su Yu followed Naruto when he stole the Scroll of Sealing and found the Flying Thunder God formula within it. He and Naruto then defeated Mizuki: Su Yu restrained the Chunin with Shadow Possession while Naruto overwhelmed him with Multi Shadow Clone Technique. 3 4

Anbu training and the Hyuga Clan

Su Yu was placed under Uzuki Yugao’s instruction because of his parents’ sacrifice. She taught him specialist taijutsu training and Konoha-Style Kenjutsu, while Su Yu used weighted gear and his Uzumaki recovery to train for extended periods. 5 6

He befriended Hinata Hyuga by offering to train her, then used their sparring to acquire the Hyuga bloodline, Byakugan, Gentle Fist, Rotation, Eight Trigrams Vacuum Palm, and Chakra Sealing Palm. Hyuga Hiashi recognized Su Yu’s command of Gentle Fist and asked him to instruct Hinata and Hanabi. 7 8

Land of Waves mission

During a mission to protect Tazuna, Su Yu sought out Yuki Haku and Zabuza, proposing that they eliminate Gato and gain independence from his control. He trained with Haku, disclosed his Byakugan, and tried to persuade him that he was more than Zabuza’s tool. 9 10

Using heavy fog, Byakugan, and Shadow Clones, Su Yu infiltrated Gato’s building, killed Gato, stole his wealth, and set the building ablaze. The bridge project resumed, and Su Yu continued sparring with Haku before returning to Konoha. 11

Rise through Anbu

Su Yu trained until he reached Chunin-level chakra, then passed an Anbu Chunin assessment by stealing an intelligence scroll from three Anbu Chunin and bypassing Kurenai Yuhi’s genjutsu. Afterward, he studied sealing jutsu, medical ninjutsu, elemental transformations, and Konoha-Style Kenjutsu. 13 14

He mastered Great Fireball Technique, Water Prison Technique, Rasengan, Healing Technique, Chakra Scalpel, and a modified version of Adamantine Sealing Chains. He also trained Haruno Sakura in medical ninjutsu and helped Naruto, Sasuke, and Sakura recognize weaknesses in their combat styles. 15 17

The Third Hokage formally placed him in the Anbu Intelligence Division, providing a custom cat mask, armor, arm guards, ninja sword, and cloak. 17

Chunin Exams and departure

During the Chunin Exams, Su Yu upgraded Hell Viewing Technique to S-rank, obtained the Two-Tomoe Sharingan, and secretly monitored Hinata with Mind’s Eye of the Kagura. He rescued Anko Mitarashi after her clash with Orochimaru and promised Karin Uzumaki that he would help her escape her mistreatment. 20 21

He signed a Summoning Contract with Sage Katsuyu, who entrusted him with an Uzumaki sealing scroll. Su Yu was subsequently transferred to the Hokage Direct Squad, giving him greater access to ninjutsu scrolls through Hiashi. 23 24

Su Yu later upgraded to the Three-Tomoe Sharingan. During Konoha’s invasion, he saved Hinata and Hanabi, cooperated with Naruto and Gamabunta against Shukaku, sealed away one of Shukaku’s arms, stole Tsunade’s medical notes from the Hokage Office, killed the imprisoned Mizuki, and left Konoha. 26 27

Land of Waves base and later research

After leaving, Su Yu established himself on property he purchased along the Land of Waves coast. Tsunade sent Uzuki Yugao to remain at his side as both a liaison and observer, while Karin and nine young ninja trainees joined his household. 29 30

He completed the authentic Adamantine Sealing Chains by extracting Shukaku’s chakra, then incorporated it into his Wind Style: Rasenshuriken research. He later took Nine-Tails chakra from Sora without killing him, stabilized a three-tailed Tailed Beast Cloak, and developed Wind Wings and a Wind Barrier. 30 32

Su Yu researched Ice Release by studying Haku’s techniques and eventually succeeded in fusing Wind and Water chakra. He later confronted the Three-Tails, defeated Sound Four members Jirobo and Tayuya, and gained Orochimaru’s recognition. 33 35 37

He maintained ties with Konoha, providing Tsunade with his Rasenshuriken, Wind Release Chakra Mode, and medical-ninjutsu research. While investigating the Ancient Kingdom of Roran, he absorbed the Dragon Vein’s power and discovered a means to travel through time and space. 40 46 47

Personality

Su Yu is intensely ambitious and views strength as essential for survival. From early on, he planned to remain hidden while cultivating power, intending to use Orochimaru, the Sharingan, and eventually the Akatsuki as steps toward his own goals. 2

He is methodical in training and research, frequently using Shadow Clones to maximize his time and experimenting with bloodlines, Tailed Beast chakra, sealing, and chakra-nature fusion. He treats combat as a practical problem, preferring information, control techniques, ambushes, and preparation over direct confrontation. 11 13 32 33

Despite his calculating nature, Su Yu repeatedly protects people he considers important or useful. He trains Hinata, rescues Anko and Karin, provides guidance to Haku, and remains attentive to Uzuki Yugao after Gekko Hayate’s death. 7 10 21 24

Abilities & Skills

Ability Extraction System

Su Yu’s system rewards completed achievements with ability-draw opportunities and periodically issues advancement missions.

  • His initial ten draws granted Genin-level chakra, Uzumaki and Uchiha bloodlines, Shadow Possession Technique, and the Three Body Technique. 1
  • Extracted abilities can be consumed to upgrade other extracted abilities; he used Multi-Size Technique and Shadow Possession Technique to raise Hell Viewing Technique to S-rank. 20
  • He upgraded the Uchiha bloodline to Three-Tomoe Sharingan by consuming an Ice Release bloodline. 26
  • Failure of certain advancement missions can result in the loss of a skill. 20

Dōjutsu and Sensory Skills

Su Yu possesses both Sharingan and Byakugan, allowing him to combine visual perception, genjutsu, chakra observation, and close-range chakra disruption.

  • Byakugan — Perceives chakra flow and targets through obstacles or mist; enabled him to track Zabuza’s group, locate Shukaku, and identify hidden Kumogakure ninja. 8 10 26 27
  • Sharingan — Progressed from One-Tomoe observation to Two-Tomoe copying and finally Three-Tomoe genjutsu. 2 20 26
  • Hell Viewing Technique — S-rank genjutsu that forces targets to confront their deepest fears; Su Yu used it to subdue Sora and accidentally killed Mizuki through the terror it induced. 20 27 31
  • Mind’s Eye of the Kagura — Tracks chakra signatures over distance; used to watch Hinata’s team and locate Sora. 20 31
  • Limitation: Su Yu initially concealed his Sharingan and avoided activating it outside his room to prevent discovery. 2 5

Taijutsu and Gentle Fist

Su Yu’s rapid physical growth is supported by Uzumaki stamina, weighted training, specialist instruction, and mastery of Hyuga techniques.

  • Konoha-style taijutsu — Reached Chunin-comparable proficiency after one week of weighted training under Yugao’s program. 5 6
  • Gentle Fist — Uses chakra-point strikes to disrupt an opponent’s chakra flow; he employed it against Sasuke and taught its principles to Hinata. 7 8 15
  • Chakra Sealing Palm — Injects chakra into an enemy to interfere with their chakra circulation and temporarily impair ninjutsu use. 7
  • Rotation and Eight Trigrams Vacuum Palm — Hyuga Clan techniques acquired through the system. 7
  • Eight Inner Gates — Received the training method from Kabuto and later extracted the skill itself. 2 26

Ninjutsu

Wind Release

Su Yu developed several Wind-nature techniques through Rasengan research and Tailed Beast chakra integration.

  • Wind Style: Rasenshuriken — S-rank technique developed from Rasengan; initially dangerous because Su Yu could not throw it without self-injury. 30
    • A One-Tail chakra version is more efficient and inflicts sustained damage through tiny wind blades. 36
    • A Nine-Tails chakra version has substantially greater destructive power but higher chakra demands. 36
  • Wind Release Chakra Mode — Uses controlled wind thrust for speed, evasive movement, barriers, and close-range cutting force. 32
  • Wind Barrier — Blocks Haku’s Ice Senbon and Great Ice Kunai; can shatter Demonic Mirroring Ice Crystals when combined with Su Yu’s strikes. 32
  • Wind Wings — Wind-based flight method, though it consumes considerable chakra. 35

Sealing and Tailed Beast Chakra

Su Yu’s Uzumaki heritage supports his sealing research and use of Tailed Beast chakra.

  • Adamantine Sealing Chains — Reconstructed from a modified version, then completed after extracting chakra from Shukaku’s severed arm. 15 30
    • Can bind targets and seal Tailed Beast chakra for later use. 15 30
    • The sealed chakra acts as a catalyst that continuously condenses further chakra of the same Tailed Beast. 30
  • Tailed Beast Cloak — Stabilized a three-tailed cloak using Nine-Tails chakra. 32
  • Three-Tails chakra — Enhances his Water Release and, together with Wind Release, enables Ice Release. 47
  • Dragon Vein absorption — Used Adamantine Sealing Chains to extract the Dragon Vein’s vast chakra reserve from Roran. 46

Medical Ninjutsu

Su Yu learned medical techniques through scroll study and Tsunade’s notes.

  • Healing Technique — Stabilized Anko’s injuries and treated Jirobo and Tayuya after defeating them. 21 36
  • Chakra Scalpel — Learned as part of his medical-ninjutsu training. 15
  • His chakra control, built through Tree Climbing, Water Surface Walking, and Rasengan training, accelerated his medical progress. 15

Ice Release

Su Yu developed Ice Release rather than inheriting it directly.

  • Studied Haku’s Ice Kunai and other Ice Release techniques to understand chakra fusion. 32
  • Built an ice cellar and spent half a month refining Wind- and Water-nature chakra until he could form ice sculptures. 33
  • Initially could only use Ice Release reliably in extremely low-temperature environments. 40

Summoning and Time-Space Techniques

  • Sage Katsuyu Summoning Contract — Signed at Shikkotsu Forest due to his Uzumaki lineage; the size of the summoned slug depends on his chakra expenditure. 23
  • Katsuyu can transport him to Shikkotsu Forest in a crisis and relay messages or items between Su Yu and Tsunade. 23 29
  • Dragon Vein time-space travel — After reactivating the Fourth Hokage’s sealing jutsu in Roran, Su Yu traveled to Konoha during the Third Hokage’s era to investigate the past. 47
