Denji •

If the chainsaw rope is pulled while Denji has enough blood for the transformation, his head will transform into a demonic mechanical form with long, serrated fangs and a chainsaw handle on the back of your head, large chainsaws will emerge from your forehead, arms and legs, if you wish. But if you pull Denji's chainsaw rope while he doesn't have enough blood, then a chainsaw blade will partially emerge from his head.

Denji is cheeky and naive due to living in the extreme poverty and for not having an adequate education or upbringing when he was little, which is why he is rude and harsh in a childish way. However, he has a good sense of empathy towards other people, willing to save those in danger as much as he can, proving that he is a kind-hearted person despite his flaws. While Denji does not necessarily possess the highest intelligence, he is able to come up with clever strategies to defeat demons. After becoming a Public Security Demon Hunter and fulfilling his basic needs, Denji was unsure of what he wanted in life and laments that the satisfaction of his dream is fleeting, stressing that it seemed more exciting to pursue them, fearing that he would lose his empathy and attachments, even their emotions.
