Power Progression

Stage / Realm / Level	Chapter	Notes
Beginner Flowing Iron Block	11	Hardens his palm after three demonstrations and five explanations. Initially sustains it for half a second, with shaking afterward; later practices shorter activations during handstand push-ups.
Improved localized chakra control	25	His chakra flows more smoothly than Obito’s, but becomes unstable when he attempts to solidify it into localized hardening.
Life Return — first version	31	Learns Makoto’s chakra-circulation method for strengthening the body. Early practice produces only modest gains.
Above ordinary first-year combat ability	32	After learning Flowing Iron Block and Life Return, is assessed by Makoto as capable of beating higher-grade students. Defeats Akimichi Kosuke with one kick.
Life Return 2.1	39	Receives a version that raises training speed to roughly 3.5 times normal and improves physical vitality. Two months of practice sharply improves his taijutsu.
Further physical growth	40	Can kick a wooden training post to splinters. Remains superior to Obito, who can now withstand roughly a dozen exchanges before losing.
High-speed taijutsu sparring	64	Uses high-speed movement against Makoto’s Shave: Flash Step. Their movements are too fast for Obito and Shisui to follow.
Genin-level ability and enhanced ninjutsu potential	66	Makoto assesses him as strong enough to graduate early. Through Shisui’s belief, Makoto has secretly given Guy and Obito a small increase in ninjutsu talent.
Water-walking training	66 67	Begins training to improve chakra control and prepare for Moonwalk. His first attempt lasts only a few seconds; he continues practicing through repeated failures.
Early graduation — Genin	75	Graduates early from the Ninja Academy alongside Obito and begins serving as a Konoha genin.
Shave footwork training	153	Practices Shave under Makoto’s supervision. His forceful steps produce muffled booms and leave shallow footprints; full mastery is not established.
Chunin promotion	155	Receives a Chunin appointment letter as Konoha accelerates advancement amid rising mission danger and approaching war.

Appearance

• Green outfit: Wears his signature green clothing while running around Konoha and a green jumpsuit during the practical exam 7 32.
• Family resemblance: Closely resembles Duy, whose distinguishing features include thick eyebrows and a bowl haircut 32.
• Expressive gestures: Frequently gives thumbs-ups and flashes gleaming white teeth when encouraging others 2 10 11.
• Forehead protector: Wears a Konoha forehead protector after his early graduation 75.

Personality

Guy treats strenuous training as an expression of “youth.” He welcomes Makoto into his running routine, describes shared sweat as a way to strengthen friendship, and continues practicing even when exhausted. Makoto recognizes that praise will not make him slack off 7 11.

His enthusiasm is tempered by concern for his friends. Before testing Iron Body, he hesitates because he fears hurting Makoto. After injuring his own fist, however, he celebrates the technique’s apparent success instead of dwelling on the pain. He is also considerate about money, worrying over Makoto’s ramen bill and promising to return the favor 8 20.

Guy’s straightforward trust makes him particularly susceptible to Makoto’s deception. He readily accepts Makoto’s claims about invented techniques, although he does ask practical questions about their mechanics. Excitement can also make him overzealous: after knocking down a classmate, he apologizes when Nakamura reminds him that sparring is not a fight to the death 8 18 30.

He generally focuses on immediate training goals rather than distant technical possibilities. During water-walking practice, his priorities are mastering the exercise, learning Moonwalk, and becoming stronger; he repeatedly tries again despite being soaked by his failures. His first unsuccessful attempt nevertheless brings a comic excuse about external conditions rather than an admission of poor chakra control 66 67.

Friendly competition further increases his effort. Kakashi’s dedication to Shave prompts Guy to declare that he will double his own training. Promotion brings similarly exuberant pride: he celebrates becoming a Chunin with a standing backflip and a declaration to his father, then vows to work harder and catch up with Makoto. The growing danger of their assignments subsequently gives Guy and Obito greater seriousness about their responsibilities 153 155.

Abilities & Skills

Taijutsu and Physical Conditioning

• Exceptional endurance: Plans a ten-lap run around Konoha—approximately fifty kilometers—and remains neither flushed nor breathless after fifteen kilometers, while Makoto struggles to continue 7.
• Powerful strikes: His punch knocks Makoto back several steps during the iron-plate test. In Academy sparring, he defeats a bespectacled opponent with one punch 8 18.
• Speed and timing: Evades Kosuke’s enlarged-hand attack with a leap, then knocks him unconscious with a downward kick before he can react 32.
• Rigorous conditioning: Practices handstand push-ups and completes a thousand-push-up set 10 27.
• High-speed movement: During a spar with Makoto, moves fast enough that Obito and Shisui cannot follow the exchange. The passage identifies Guy’s movement as high-speed movement, not specifically as Shave 64.
• Shave training: Later explicitly practices Shave’s basic footwork. His approach emphasizes forceful, sweeping movement, with each stamp leaving a shallow footprint in the ground 153.
• Planned development: Makoto intends for him to thoroughly master Life Return, refine the Six Powers taijutsu, and eventually train in the Eight Gates Formation. These are projected goals rather than confirmed mastery; Makoto particularly wants him to avoid opening the Gate of Death 153.

Iron Body and Flowing Iron Block

Makoto teaches Guy defensive hardening techniques that reinforce the body with chakra 11 18 24.

• Iron Body: Initially considers full-body hardening too passive because it prevents movement. Obito’s victory shows him its potential for absorbing an opening strike and immediately counterattacking 18.
• Flowing Iron Block: Learns to harden selected areas rather than immobilize his whole body. His first successful palm hardening lasts only half a second 11.
• Control limitations: Later practice still produces unstable hardening. Makoto explains that only unhardened body parts can move at their current level 25.

Life Return

• Training method: Circulates chakra through the body to improve vitality and strength rather than providing only a temporary combat enhancement 30 31.
• Version used: Receives Life Return 2.1, not Makoto’s much stronger personal version 7.0 39.
• Observed results: His taijutsu improves sharply after two months, followed by enough kicking power to splinter a wooden post 39 40.
• Long-term importance: Makoto regards deeper mastery of the Life Return system as a foundation of Guy’s future taijutsu-focused development 153.

Ninjutsu and Chakra-Control Limitations

• Clone Technique: Produces unevenly proportioned clones—one fat and one thin—because his chakra output is unstable 24.
• Substitution Technique: Can perform substitutions but has difficulty controlling his destination; once becomes stuck in a tree 24.
• Moonwalk prerequisite: Makoto considers his physical fitness sufficient for Moonwalk, but refuses to teach him until his chakra control and Flowing Iron Block improve. No successful use by Guy is documented 27 28.
• Secret talent enhancement: Makoto uses Shisui’s trust to manifest a small improvement in Guy’s and Obito’s ninjutsu talent. Guy is unaware of the supernatural source of this enhancement 66.
• Water walking: Begins learning at the river beside the Third Training Ground. He initially stays on the surface for only a few seconds before falling in, then perseveres through repeated attempts. Makoto presents the exercise as both chakra-control training and preparation for Moonwalk 66 67.
• Interest in Fire Release: Asks to learn a Fire Release technique when Makoto promises Obito one as a reward for defeating Asuma. This request does not establish that Guy learns or successfully uses the technique 70.
• Later assessment: Makoto considers his chakra reserves decent but still describes his chakra control as poor and his ninjutsu aptitude as extremely limited compared with his exceptional taijutsu talent 153.

Relationships

• Might Duy — Father. Rushes onto the exam field to embrace Guy after his victory; the pair celebrate tearfully with declarations about youth and passion. Guy later invokes his father while celebrating his Chunin promotion 32 33 155.
• Uchiha Makoto — Friend and instructor. Teaches Guy defensive taijutsu and Life Return, encourages him to rest, and treats him to ramen. Unknown to Guy, Makoto also exploits his trust to manifest abilities. Guy calls Makoto his “lifelong rival” after a high-speed spar. Makoto continues teaching him chakra control and Shave after becoming a working ninja, while planning a development path centered on taijutsu 8 11 20 39 64 66 153.
• Obito Uchiha — Classmate, training partner, and sparring rival. They practice basic techniques together and inspire each other’s ambitions; Guy consistently retains the advantage in taijutsu. They later graduate early together and both receive Chunin promotions 18 23 25 34 40 75 155.
• Kakashi Hatake — Friend within Makoto’s wider social circle and a competitive training partner. They attend the celebration of Guy’s and Obito’s graduation and later practice Shave together. Kakashi’s hard work inspires Guy to intensify his own training 75 153.
• Shisui Uchiha — Member of their shared training and friendship circle. Congratulates Guy on his early graduation. Unknown to Guy, Shisui’s belief also helps Makoto enhance his ninjutsu potential 64 66 75.
• Teacher Nakamura — Academy teacher. Oversees Guy’s matches and reprimands him for using excessive force during sparring 18 32.

Story Role / Major Arcs

Enabling Makoto’s Invented Techniques

Guy becomes one of Makoto’s principal sources of belief after progress through Obito begins to plateau. His complete trust produces a documented 70% manifestation rate; this strengthens Makoto, not Guy directly 7 8.

Technique	Guy’s contribution
Iron Body	Mistakes a concealed iron plate for Makoto’s hardened body. His belief manifests the actual technique at 70% 8.
Flowing Iron Block	Believes Makoto has completely mastered localized hardening. His contribution combines with Obito’s earlier belief to bring manifestation to 100% 10.
Moonwalk	Accepts Makoto’s claim that he can briefly step through the air, enabling its initial 70% manifestation 27.
Life Return’s underlying cultivation method	Joins Obito in believing that Makoto can create a chakra-circulation method that permanently strengthens the body. The displayed initial manifestation is attributed to Obito, rather than a separately measured contribution from Guy 30.
Secret experimental base	Believes approximately 40% of Makoto’s claim that he possesses a large, multifunctional base. Makoto later obtains further belief from Kakashi, producing an expanded two-level laboratory 97.
Sharingan improvement	Continues accepting claims about Makoto’s increasing ocular abilities during the months preceding the Four-Tomoe Sharingan mutation 99.
Warning of intense pain	Responds with faith and concern to Makoto’s warning of an approaching painful ordeal. His belief forms part of a five-person effort whose combined manifestation reaches 111% 190 191.

Guy’s expectations also influence the quality of the results: imagining Iron Body as capable of blocking swords produces tougher hardening than Obito’s simpler conception 11.

Makoto additionally uses Guy’s belief in his rapid chakra growth, taijutsu talent, and physical strength to obtain incremental improvements over time. These gains belong to Makoto and should not be confused with Guy’s own training progress 23.

The laboratory claim demonstrates that Guy’s trust is not uniformly complete. Makoto considers his partial acceptance satisfactory given Guy’s concentration on taijutsu and the scale of the boast. A promise that Guy will receive the first test puppet greatly excites him, but the context does not confirm delivery of that puppet 97.

Academy Recognition

At the Year 41 practical finals, spectators dismiss Guy because Duy is a perpetual genin. His immediate victory over Akimichi Kosuke overturns their expectations and makes him known to the audience 32.

Makoto’s Graduation

At Makoto’s graduation dinner, Guy and Obito worry that missions will leave them with less time together. Makoto promises to continue teaching them whenever he is in Konoha 46.

Continued Training and Early Graduation

Makoto keeps his promise by continuing to spar with Guy and teach him alongside Obito and Shisui. In one high-speed taijutsu session, Guy declares Makoto his lifelong rival after an exchange that the other two boys cannot follow 64.

After approximately a year of instruction, Makoto judges Guy and Obito to have Genin-level strength and plans for them to graduate in their second Academy year. He begins teaching them water walking to strengthen their chakra control and prepare them for aerial movement. Guy repeatedly fails but remains focused on mastering the exercise 66 67.

When Asuma challenges Makoto, Guy is named alongside Obito as an opponent Asuma must first defeat. Guy eagerly wants to fight, but Obito volunteers first and wins. Guy subsequently asks for Fire Release instruction and increases his taijutsu practice 69 70.

By Year 43, Guy and Obito have both graduated early and become genin. Makoto celebrates with a barbecue gathering attended by Kakashi, Shisui, and Rin 74 75.

Advanced Training and Chunin Promotion

Guy continues training under Makoto at a secret training ground. He and Kakashi arrive fifteen minutes early to practice Shave without prompting, then spur one another to work harder. Makoto envisions Guy becoming a powerful taijutsu specialist through Life Return, the Six Powers, and eventually the Eight Gates. The session ends at nightfall with a shared meal at Makoto’s restaurant 153.

As war approaches and missions become more frequent and dangerous, Guy and Obito receive Chunin appointment letters. Guy celebrates with a standing backflip, a thumbs-up, and a declaration that the promotion is the fruit of his burning youth. He congratulates Makoto on becoming a Special Jōnin and resolves to catch up with him 155.

Guy and Obito also help Makoto put together the roster for his own squad, consisting of Makoto as leader and Uchiha Nako, Uchiha Shun, and Uchiha Entetsu as members 157.

Belief in Makoto’s Approaching Ordeal

Before Makoto’s deployment to the Land of Hot Water, Guy is among the friends whose belief helps manifest a warning of intense pain. Makoto’s aim is to create conditions that might trigger his Mangekyō Sharingan, rather than to manifest the eye directly. Guy responds through straightforward trust and concern; the combined effort reaches 111% manifestation 190 191.

Makoto subsequently experiences near-fatal agony from Kumogakure’s Golden Circlet and awakens his Mangekyō Sharingan. Guy contributes to the earlier belief-based setup but is not present in that battle 201 202.
