Denji is brash and naive due to living in extreme poverty and not having a proper education or upbringing as a child, resulting in him being rude and harsh in a childish manner. However, he has a good sense of empathy towards other people, willing to save those in danger as much as he can, showing that he is a kind-hearted person despite his flaws. While Denji does not necessarily possess the highest intelligence, he is capable of devising clever strategies to defeat demons, such as the time he set himself on fire and used light to weaken Santa Claus enough to incapacitate him.[8]

After becoming a Public Security Demon Hunter and having his basic needs met, Denji was unsure of what he wanted in life and laments that the fulfillment of his dream is fleeting, stressing that it seems more exciting to pursue them, fearing that he will lose his empathy and attachments, even his emotions.

Makima was Denji's love interest and affection, being the first woman he had ever hugged, as well as proposing a life of his desired comforts, which led him to propose to her, follow her lead without hesitation, and become more interested in physical-affective acts with women, which he already strongly desired since before fusing with Pochita. According to the author, Makima also played a role close to a maternal figure for Denji.

Said by Makima, Aki and Power played the role of older brother and younger sister respectively for Denji, revealing the reason why he did not feel any lascivious desire towards Power being naked and in physical contact with him, also emphasizing why it hurt him emotionally so much to have ended Aki's life and see before his eyes how Power was killed by Makima, being that before he did not care that both of them died.

Desperate to love and be loved, Denji became emotionally dependent on Makima as a survival mechanism, even going so far as to tell her that his wish was to be her mindless dog and obey her commands, though hesitant to do so, he did not stop following them even after she ended Power's life in front of him, revealed her deepest trauma, broke into mocking laughter and confessed her entire plan to make him break his contract with Pochita; in the process Denji mentally broke down to a state similar to a dog obedient to Makima.

Denji's mental disturbance led him to such an extent that he did not intend to kill Makima, but to become one with her, which helped him in the end to deduce that he would be capable of killing her as an act, although twisted, of love.

Currently, Denji's mentality is shown to be more stable, retaining his cheeky attitude, his lust and his madness recognized by Himeno, however, according to his talk with Asa to rescue her, it shows that he has a somewhat pessimistic and realistic point of view of life, but unlike her, he maintains an objective that keeps him relatively free from falling completely into depression, and that is to have sex a large number of times, although Asa's comments made him doubt and fall under the effects of the Demon of the Fall.

Denji has no qualms about saving people from demons, however, he tends to have a markedly greater appreciation for women, being much more cruel or even coldly concerned about victims who are men.

Denji is a teenage boy with scruffy blond hair, brown eyes and dark circles under his eyes, making him look tired, and his teeth are noticeably sharp and angular; due to malnutrition in his childhood, he is very thin and even has prominent ribs. Before fusing his heart with Pochita's, Denji was missing his right eye which was covered by an eyepatch and several other non-essential organs, including a testicle and a kidney. [1] During this time, he also wore a loose white sleeveless undershirt, a green jacket, and black pants.

After Denji's heart fused with Pochita's, a chainsaw cord appeared in the middle of his chest and he regained his lost organs.[2] He spends much of his time wearing the standard Public Security Demon Slayer uniform, consisting of a white shirt, tie, and pants, but dresses with the shirt wrinkled and the sleeves rolled up.

If the chainsaw's cord is pulled while Denji has enough blood for the transformation, his head will transform into a demonic mechanical form with long, jagged fangs and a chainsaw handle on the back of his head, large chainsaws will emerge from his forehead, arms, and legs if he wishes.[4] But if Denji's chainsaw cord is pulled while he does not have enough blood, then a chainsaw blade will partially emerge from his head.[5] When Denji leaves this form and returns to his human form, the changes that occurred turn into a liquid-like layer and melt away.

When Denji let the Chainsaw Demon (Pochita) take control of him, his intestines emerged from his stomach and wrapped around his neck, resembling a scarf.[6] Once transformed, his body is black and appears to be covered in armored plates or scales, gaining spikes on his shoulders and the back of his head, but losing the handle on his back; in this form, he becomes much larger and bulkier, having four arms, each equipped with its own chainsaw blade.[7]

Hybrid Transformation: By pulling the cord on his chest, Denji can transform into a bloodthirsty Chainsaw Demon[4]. Enhanced Strength: Denji has enough strength to catch a thrown car in the air without wobbling and throw it back with force.[10] He was also able to throw his own heart hard enough to pierce through Earth's atmosphere and avoid being lost in space.[11] Enhanced Durability: Denji withstood a point-blank blast from the Bat Demon that destroyed the building behind him, getting back to his feet to continue fighting.[12] He has survived multiple explosions and has been on fire for long periods of time. Chainsaw Manifestation: As part of his transformation, Denji develops fully functional chainsaws from his arms, legs, and head, which are extremely effective at slicing through demons. He is even able to manifest short chainsaws under his feet, which he can stick into walls and even walk on. As a full demon, all four of his arms have chainsaws. Chainsaw Retraction: Should he need full use of his arms and legs, Denji's chainsaws automatically retract into his body.[13] However, this has not been seen in his demon form. Chain Entanglement: Denji can disconnect his chains from his chainsaws to wrap around his opponent's body and pull them closer to him.[14] If Denji's arms are torn off, but still connected to his body, he can still use his chain as body tissue to wrap around his enemies. Demonic Transformation: After renouncing his contract with Pochita, Denji transformed into the Chainsaw Demon, displaying incredible speed and strength, easily defeating multiple Hybrids in a matter of seconds. His immense power is further highlighted in Hell, where it is implied that he defeated all the demons residing there. This transformation lacks his original personality and consciousness.
