For a short amount of time, he can become a demon using his bite strength and his special digestive organs." Basically, as a result of his serious gnashers and iron stomach, Genya can devour demon flesh and gain characteristics like the sharpened fangs, frosted tips, and black pupils seen in the most recent episodes.
By devouring demon flesh, Genya gains demonic characteristics, such as fangs, dark sclera, and unique yellow tips in his hair.
No, Genya is not a demon in Demon Slayer: Kimetsu no Yaiba. His demon-like appearance is simply due to his power that helps him consume demon flesh without any adverse effects. He gains the characteristics of a demon, like fangs, changed eye color, and others but does not turn into a demon himself.
Demon Slayer's Genya Can Eat Demon Flesh
This allows him to temporarily gain demonic abilities, such as regeneration or heightened strength, making him immortal while in demon form.
Why does Genya eat demons? He consumes demon flesh because it allows him to temporarily gain that demon's abilities despite being a human. This is a power that is unique only to him. In the latest episode of Demon Slayer, fans could watch him recite the Amida Sutra.
In the simplest terms, the reason that Genya can't use Breathing Styles stems from his inability to achieve the total concentration breathing that other demon slayers use in order to access their abilities.
The most accurate assumption to make here would be that he cannot perform concentration breathing and improve his breath. This is something that is quite intuitive and the main reason for his inability to perform said techniques is probably because he lacks the natural talent to do so.
Due to his brother, Sanemi's criticism and his lack of power, the young and desperate Genya consumes demon flesh in order to become stronger. However, that takes away his ability to use breathing techniques, which is why Genya is unable to master swordsmanship.
After being attacked by nichevo'ya, or the nothings, her skin is scarred all over, and she has one remaining eye.
Genya Safin is a Tailor, a hybrid Grisha who has the power to alter people's appearances. Because of her unique gifts she has been placed in service to the Queen of Ravka, a situation that has isolated her from other Grisha and made her an outcast among her own people.
Sanemi was angry with Genya joining the Demon Slaying Corps as that would've made all his work and dedications to his job pointless- he joined so that Genya could have a normal, happy life, yet there he was; risking his life trying to apologize to Sanemi about something that he had already been long forgiven for.
Abilities and Powers
Demonic Transformation: By consuming the live flesh of a Demon, Genya could temporarily gain demonic attributes from it. Depending on the strength of the individual, he could gain regeneration and physical strength equal to one.
Genya remains loyal to the Darkling, but his nichevo'ya mutilate her when she betrays him to help Alina escape in Siege and Storm. She joins Alina and helps in taking the King down. She marries David Kostyk and becomes a member of the Grisha Triumvirate.
Genya was sliced up by Kokushibo, but the consumption of his hair allowed him to regenerate immediately. He also consumed Kokushibo's sword which was made out of his flesh. In the end, Kokushibo and Genya died without fully realizing the love their brothers had for them.
Genya is considered a weaker Demon Slayer, since the Upper Moon 1 acknowledged him to be the smallest threat during his battle against Genya and multiple Hashira.
Genya Shinazugawa is not a demon in the series. He is a human and utilizes his unique abilities to fight against demons and protect humanity. While Genya's ability to consume demon flesh may have raised questions, it is a result of an experimental procedure and not an indication of his demonic nature.
Demon Slayer: Kimetsu No Yaiba, Volume 20 continues as the Demon Slayer Corps' initial confrontation with the most powerful of Muzan's demons, Kokushibo, has left Tokito severely wounded and Genya cut in half. Miraculously Genya is still alive hoping that his regenerative power can heal even his fatal wound.
(Genya wears white because she's a servant of the Little Palace.)
He asked impatiently about getting his Nichirin Sword, striking both his crow and Katana violently when his request went unfulfilled. Tanjiro interfered, if he didn't let his hands off Kanata immediately promised to break his arm. Then, when Genya dared him, Tanjiro pushes, leaving him with a broken limb.
Ruin and Rising
Alexander III wants Genya to be beheaded for high treason and murder, while it becomes clear that he raped her. Genya confesses that she poisoned her own skin so that the king would consume it when he kissed and touched her.
The bullets he uses are made of Scarlet Crimson Iron Sand and Scarlet Ore, allowing him to kill demons without a blade.
The emerald green blade also represents wind breathing and is seen by Wind Hashira, Sanemi Shinazugawa. The abilities that come with his green sword is being fast like a tornado whilst also staying extremely calm.
5 Genya Shinazugawa
Genya was killed by the Upper Moon 1, Kokushibo, but not before helping the others take him down. As he was dying, his brother Sanemi regretted how strained their relationship have become, and wept as he begged the heavens to spare Genya.
Genya is moved to tears and apologized after hearing Sanemi's reasoning behind his rudeness. After their battle with Kokushibou, Genya apologized again for blaming Sanemi and thanked his brother for protecting him before succumbing to his wounds and crumbling into dust, leaving Sanemi stricken with grief.
He then used his gun and sword to behead Karaku and Sekido, only to reveal two more of his personalities, Aizetsu and Urogi. While Urogi takes Tanjiro up in the air, Aizetsu stabs Genya with his sword and lifts him up in the air, passing the sword completely through his body.
