Appearance[]
At the time of his debut during Final Selection, Genya was a short young man with a rough appearance to him and fair skin tone. The space where his eyebrows would've been is constantly furrowed, which gave him a perpetually angered appearance. His hair is styled into a buzz cut, with only a small clump of messy black hair left to grow on the top of his head. He also possessed a large, jagged scar that ran over his right cheekbone from his ear and to over his nose. Genya is seen wearing a purple, sleeveless yukata over a plain black shirt with long sleeves.
Later on, when seen again in the Butterfly Mansion, Genya, having hit puberty, had a much more feral appearance. He had undergone a growth spurt that made him nearly six feet tall, with inward-slanting, large almond-shaped eyes featuring purple irises similar to Sanemi's. His hair was now longer, styled in a mohawk-like fashion with strands framing his neck. His boyish features had toned down, replaced by a more muscular physique and numerous scars across his body. Genya's outfit had changed to a dark olive-green version of the Demon Slayer uniform, worn under his old purple yukata, and he also wore a pair of white jika-tabi.
When he meets Tanjiro again in the Swordsmith Village, Genya's physical appearance was less intense and intimidating, and although still tall and rugged, his more youthful features were visible. By the time Hashira Training had commenced, his eyes became softer and less wild, and his expression is visible less sullen and harsh, coinciding with his newly gain maturity and sense of camaraderie.
As a child, Genya sported a similar-looking mohawk to his matured appearance and he wore the same sleeves purple yukata over a black long-sleeved shirt. He received his signature scar from an attack by his transformed mother.
After consuming a piece of Aizetsu's flesh, Genya gained many physical qualities reminiscent of a demon. The tips of his hair gained yellow highlights, his mouth grew fangs, and his eyes became a demonic combination of black sclera and yellow irises.
After consuming a piece of Kokushibo's broken flesh sword, he grows features identical to the Upper Rank demon, such as having his longer curled hair, veiny-patterned eyes with golden irises and red sclera, and a Demon Slayer Mark resembling his, although it is unknown if this was an imitation of Kokushibo's physical features or a genuine Mark.

Personality[]

Genya refusing Tanjiro's offer for a rice cracker.
Genya was initially a foul-mouthed and ill-tempered individual; a "lone wolf" who refused any help from others and did not show any interest in being polite or having any manners. During Final Selection, he roughly handled Kanata Ubuyashiki by grabbing her hair and yelling at her due to his impatience, and he later provoked Tanjiro Kamado into directly confronting him with physical force as an attempt to diffuse the situation. His ill temper and brash way of speaking heavily resembles that of his older brother, Sanemi.
He became more open to cooperation during the battle against Hantengu, the Upper Rank Four, where he worked alongside Tanjiro, Mitsuri Kanroji, and Nezuko Kamado. After some time, he learned to become more sociable and less ill-mannered towards others, particularly towards Tanjiro and his friends. Genya also appears to be very confident in battle, telling Aizetsu to focus on him despite the latter already having stabbed Genya with his Yari, and later announced his name to the demon and declared that he is the one who will kill him.

Even as a child, Genya was determined to protect his family.
As a child, Genya was caring and loving towards his family, looking out for them due to their father's abuse and being the second oldest of his siblings. His protective attitude stems from a promise he had made with Sanemi following their father's death, when he stated that it was now their job to be a role model for their siblings and look after their mother. He was deeply regretful of his inability to save his brothers and sisters following their mother's transformation and blamed himself heavily for his own accusation of Sanemi killing her, despite acknowledging later that he was not at fault and she transformed into an uncontrollable demon.
During Sekido's near fatal attack on Genya, he shed tears of regret when he believed he was about to die without ever getting the chance to properly apologize to Sanemi for his harsh words, only encouraged to push past it when Tanjiro had rescued him and placed his faith onto him. Sanemi's refusal to acknowledge Genya made him insecure as he came to realize just how weak he is compared to his companions. When he reunited with his brother during his section of Hashira Training, he attempts to apologize and make amends with his brother, but is left demoralized when Sanemi berates him after threatening to kill him. His desire to reconnect with his brother was so strong that he confesses his habit of eating demons to fight, knowing that the practice was taboo. Nonetheless, he did whatever he could to help his allies, even if it got him horribly maimed in the process, such as shielding Tanjiro from Aizetsu's Blood Demon Art, and playing a pivotal role in the battle against Kokushibo. Despite his brother's harsh rebukes, he bore no ill will towards him, a belief reinforced by Tanjiro and eventually by Sanemi himself.

Genya's newfound maturity and gentle personality.
His abrasive and hostile persona did not last, in part due to Tanjiro's influence and camaraderie, and the two would form a close friendship afterwards. After the attack on the Swordsmith Village, Genya is shown to be a much more pacified and caring individual, giving a warm smile when Tanjiro tearfully reunites with a now sunlight immune Nezuko, inwardly congratulating him for his happiness. Later on, when Sanemi decides to attack Tanjiro for defending him, whom he was also going to beat up, Genya pleaded with his brother to spare the Demon Slayer. When he encounters Tanjiro again while he is taking part in Gyomei's training, Genya thanks him for standing up for him during the incident at Sanemi's dojo before going on to teach him about Repetitive Action, before sharing a laugh at Gyomei's expense. In the evening, Genya offers to help Tanjiro cook onigiri and later asks Tanjiro when his emotions were most worked up in the past in an attempt to further help in his training. When he pauses, Genya immediately apologizes for potentially bringing back haunting memories and gives Tanjiro further encouragement. In spite of his new-gained maturity, Genya can occasionally slip back into his confrontational habits, most notably when he punched Zenitsu Agatsuma and scuffled with Inosuke Hashibira after they had insulted Sanemi and him respectively, though these instances were more than likely a result of these two's strong and stubborn personalities clashing with his own.
In the fight against Kokushibo, though Genya was largely indisposed due to being horizontally bisected by the demon, he still demonstrated an intense devotion to help others, as he ate a lock of Kokushibo's hair, and later willingly swallowed a fragment of his extremely sharp sword, all with the goal of protecting his mentor and elder brother. In the end, as he began disintegrating into ash, his last words were a plea to the gods to give Sanemi a prosperous life, calling his brother the nicest person in the world and thanking him for all he'd done. Tragically, this shows that despite Sanemi's own anger and mistreatment of Genya out of a misguided attempt to protect him, he loved his brother until the very end and wanted the best for him.
Abilities[]
Overall Abilities[]
As one of the five that survived Final Selection, Genya possesses a relatively strong foundation as a Demon Slayer even without utilizing a Breathing Style. His skills were exemplified in the battle against Hantengu, the fourth strongest Upper Rank, when he snuck up on two of his clones and successfully shot them both and proceeded to decapitate them in quick succession. When he consumed the flesh of Aizetsu, Genya managed to overpower the Upper Rank, stabbing Aizetsu into a tree with his own Yari and ripping off his head. When Mitsuri Kanroji, the Love Hashira, was nearly struck and killed by Zohakuten, Genya, along with Tanjiro Kamado and Nezuko Kamado, managed to save her before the attack connected. After gaining power from Zohakuten, Genya became strong enough to pick up and fling a gigantic tree without much effort, surprising the likes of Tanjiro and Nezuko, and then proceeded to throw 3 more. Genya was also capable of ripping both of Urami's arms off.
Against Kokushibo, the strongest Upper Rank, Genya consumed his hair and a chunk of his flesh katana, gaining enough strength to develop his own Blood Demon Art which played a pivotal role in the defeat of the Upper Rank demon.
Demon Slayer Abilities[]
Repetitive Action: A technique taught to him by Gyomei Himejima to help him compensate for his inability to use Breathing Styles. This technique mainly focuses on Genya repeating a set of words or phrases that assists him to focus on his given task properly and keep his mind clear and block out pain. For Genya, he repeats a set of prayer of the Amida Sutra to help him focus and steel his mind, as seen where he used this technique to focus his mind after being fatally injured fighting Aizetsu and to a degree, replicate the effects of Total Concentration Breathing.
Supernatural Abilities[]

Genya dodges Aizetsu’s attack.
Demon Consumption & Empowerment: Genya possesses unnaturally strong jaws and special digestive organs which allow him to tear off and consume the flesh of demons without any adverse effects and tear off even the likes of tree bark. By devouring demon flesh, Genya temporarily gains demonic characteristics, such as fangs, dark sclera, and unique yellow tips in his hair. Sometimes, presumably because of how concentrated a demon’s blood is, Genya can gain attributes related to the demon he devours, like when he gained Kokushibo’s eyes, hair, and Demon Slayer Mark, with his shotgun even gaining the appearance of the Upper Rank’s katana.

Genya splits Hantengu's wooden burl in half.
More importantly, Genya is able to become stronger after consuming a demon, receiving a bigger boost in power depending on the strength of the demon he consumes. For the most part, Genya gets an enhanced physical constitution (which makes up for his inability to use Breathing Styles) along with potent regeneration. The physical attributes he gained enable him to out-speed Aizetsu and nearly decapitate him, as well as pick up enormous trees and hurl them over tremendous distances quite easily, and rip off Hantengu's arm. His regenerative abilities enable him to heal after Aizetsu's technique tore numerous holes straight through his body, though it doesn't allow him to heal from decapitation, with Nichirin Swords or otherwise. It also leaves him vulnerable to Nezuko Kamado's Blood Demon Art, which normally only harms demons and objects belonging to them.
Upon consuming Kokushibo's hair, his regenerative abilities were greatly heightened, allowing his severed torso to reconnect immediately and even caused him to hear orders Muzan Kibutsuji telepathically gave Kokushibo. After eating a chunk of his katana, Genya even developed a unique Blood Demon Art.
However, as noted by Kokushibo, Genya can still be killed in this form, most likely through decapitation.
Fighting Style[]

Genya's proficiency in both marksmanship and swordsmanship.
Dual Wielding: Genya utilizes both a double-barreled shotgun with Nichirin cartridges and a Nichirin Wakizashi placed on his rear hip. He is shown to excel in blending both long-ranged and short-ranged combat against demons. Against strong targets, Genya usually sneaks up on them to fire his shotgun and switches to using his Wakizashi should he fail in doing so. Genya has quite a high degree of marksmanship, being able to shoot off Sekido's head and blow off a huge portion of Karaku's and Aizetsu's neck. He also nearly beheaded Sekido even while being shocked by electricity. It has also been stated that he is more adept at using his shotgun than his Wakizashi.[3]
Game Exclusive Techniques[]
- TBA[4] - A technique exclusive to current Stone Hashira Gyomei Himejima and his young protege Genya Shinazugawa. Genya shoots their opponent using his gun before Gyomei hurls his axe and launches them skywards. After the axe boomerangs back towards Gyomei, Genya grabs hold of the chain and is sent upwards as Gyomei hurls his flail at the opponent, with the young Demon Slayer shooting his target as the chain circles around them mid-air. Gyomei then strikes the ground with his axe and tosses up a massive boulder, which Genya grabs hold of and uses his superhuman strength to maneuver it directly on top of their target. As they falls to the ground, the target is crushed by both the boulder and Gyomei's flail which shatters it, with Genya leaping away to avoid being hit by the latter.
Blood Demon Art[]

Genya's Blood Demon Art trapping Kokushibo while stealing his blood.
Vampiric Trees: After devouring a chunk of Kokushibo's Flesh Katana, Genya developed a unique Blood Demon Art. It is formed out of his altered double-barreled shotgun, which fire's flesh cartridges that he can control the path and direction of. Once implanted into the target's body, the flesh bullets grow into gigantic trees that root into the ground, enough to trap the likes of Kokushibo for a short period of time. As long as the bullets remain in his target's body, Genya can keep activating his Blood Demon Art.
On top of being used to imprison enemies, because the trees absorb a lot of blood to grow, it can be used to prevent targets from using their own Blood Demon Arts, as shown when Kokushibo was unable to unleash a technique with a tree on his back.
Equipment[]
Double-Barreled Shotgun: Genya wields a Western-style double-barreled shotgun, which he uses to shoot down targets from afar. Instead of normal cartridges, it fires shotgun pellets made with the same metal used to create Nichirin swords, which allow him to permanently kill demons if he shoots off their necks. After consuming a chunk of Kokushibo's katana, his shotgun gained a similar appearance to the Upper Rank's flesh katana, with fleshy veins and eyes, and instead fires flesh cartridges.
Nichirin Wakizashi: In addition to his shotgun, Genya also carries a Wakizashi, a Japanese sword with a blade shorter than a katana's, with two hollow ovals as its tsuba that overlap its core and are a dull shade of brown for its handguard. Along with his sword, Genya also has a sword sheath tied to the rear of his hip.

Trivia[]
- Genya's surname contains the Nanori for "immortality, eternal life" (
不死 shinazu?) and the Kun'yomi rendaku for "river, stream" (川 kawa/gawa?). His first name contains the Go-on'yomi kanji for "mysterious, occultness" (玄 gen?) and the Kun'yomi for "all the more, increasingly" (弥 ya?). - Genya is one of the few characters in the series who does not primarily use a sword and is the only Demon Slayer named who cannot use any of the Breathing Styles.
- Instead, he uses a technique referred to as Repetitive Action, which acts as a substitute for Total Concentration Breathing. It's important to note that this technique was taught to Genya by Gyomei Himejima, who himself is a Breathing user, implying that it is possible to use both techniques in conjunction with one another.
- Generally, Genya is better at wielding a gun than a sword, as he's very good at hitting targets.[3]
- Kokushibo mentions that Genya is not the first Demon Slayer he has encountered that consumed demons to gain power.
- In contrast to his brash, somewhat abusive attitude when he was first introduced, Genya has become shy around women.[5] This is seen when he could not say a word to Mitsuri (who initially interpreted his ignorance as hostility), Kanata Ubuyashiki, who he meekly apologizes to for his past actions (which she gently accepts), and the girls who work at the Butterfly Mansion.[6][7]
- Due to his unique demon-eating powers, Genya regularly goes to the Butterfly Mansion for health check-ups.[3]
- Genya ranked 15th place in the second popularity poll with 2589 votes.
- Genya shares his Japanese and English voice actors with Garfiel Tinsel from Re:Zero − Starting Life in Another World.
- In Kimetsu Academy, Genya is a 1st year student belonging in Class Kabosu. He is the shooting club's ace, and despite his hair breaking school rules, they let him keep it since he wouldn't be able to score bullseyes with a shaved head. This is because he uses his hair to read the wind.
- He is the younger brother of math teacher Sanemi Shinazugawa. He once won 1st place in a competition but his brother stormed the place and ripped his certificate apart, all while screaming "Who cares about this shit?! Learn your damn math!!".
- His big body and angry demeanor led to him being misunderstood and friendless. This changed after the competition incident with his brother, to which the students sympathized with Genya and became friends with him.
- Genya's favorite food is watermelon.[8]
- Genya's hobby is Bonsai.[8]
- His younger self has the same English voice actor as Kamanue, Alan Lee.
Quotes[]

Tokito... If only I were stronger!! If I were a Hashira!! The more I want to help, the more my body stiffens up making it difficult for me to move. I'm scared... that I'm no use and can't protect my comrades. Why am I so weak? It's frustrating! It's frustrating to be weak."[9]
- (To himself) "I'll do it. I'm gonna do it. I have to do it. Think only about winning. I will not let my brother, or my master, or any of my comrades die!" [10]
