Jinu

Jinu has a slim frame and long limbs, giving him a height and build comparable to the other members of the Saja Boys. In his human form, he has straight black hair, dark brown eyes, pale skin, and pierced ears. In his human form, Jinu typically wears a collared shirt over an undershirt, a necklace, skinny jeans, and high-top sneakers when performing as an idol. During private meetings with Rumi, he is seen in a more casual outfit consisting of a grey sweatshirt and a black jacket.

In his demon form, he retains these features, though notable changes include light blue skin adorned with demon markings, clawed hands, sharper teeth, and yellow eyes with black slit pupils. In the Demon Realm his attire includes a traditional black jeogori jacket worn beneath a jeonbok overcoat, secured with a sejodae sash and completed with a gat.

Jinu is a charismatic yet duplicitous person who primarily looks out for his own interests. Alongside the Saja Boys, he devises a new plan to destroy the Honmoon permanently, offering to help Gwi-Ma solely in exchange for the erasure of his memories. Internally, Jinu struggles with a deep sense of shame for choosing to abandon his human family for an easy life, that was only made possible by Gwi-Ma. Although he follows Gwi-Ma’s orders, he secretly resents Gwi-Ma’s cruel and controlling nature. Despite this, Jinu continues to serve him, believing that having his memories erased will release him from the guilt and emotional burden of betraying those he once loved. Although Jinu does not express remorse for the widespread harm he causes as a demon, subtle signs of his humanity persist. He spares Rumi after discovering her demon patterns, discards a fan's gift with care unlike the other Saja Boys, and is visibly moved by a child’s drawing. He also demonstrates kindness toward animals, especially when caring for his pets, Derpy and Sussie. Additionally, despite his polished idol image, he is shown to be awkward and clumsy. For instance, he becomes flustered when an elderly woman suggests Rumi is his girlfriend. Is a mix of Nonchalant and silly

Jinu is Rumi's enemy, eventual friend, and possible love interest. It is unclear how Jinu feels due to his betrayal and dishonesty toward Rumi. Jinu is a demon who leads a demon boy band in a plan to thwart the hunters' efforts to seal the Honmoon. His primary motivation for this is his desire to erase his own memories of his human life. Rumi shows attraction toward Jinu the first time she encounters him, but he repeatedly taunts Rumi as he takes away HUNTR/X's popularity. Rumi and the other hunters confront Jinu and the Saja Boys after realizing they are demons, leading to a one-on-one fight between Jinu and Rumi. During their fight he is surprised to discover that Rumi is part demon, but helps Rumi to conceal this from her bandmates so she can assist them in combat.

Four hundred years ago, Gwi-Ma tricked Jinu into agreeing on a deal that cost him his soul. In exchange, Jinu was given the life of bliss and luxury, but had to leave his mother and little sister behind to their fate. The shame and guilt ate away at Jinu, making him susceptible to Gwi-Ma's manipulation. As a result, Gwi-Ma's marks consumed Jinu whole, making him an eternal slave and a prisoner in the demon realm.

In the demon realm, Gwi-Ma continues to manipulate Jinu by exploiting his guilt over betraying his family and Jinu's desire to forget about it. In the end, Jinu stands up to Gwi-Ma to protect Rumi, leading to Gwi-Ma's downfall. For short, Gwi-ma is basically his "King"

Jinu gathered a group of demons to form a boy band to rival HUNTR/X, thus weakening the Honmoon. The demons he chose are known under the nicknames Baby Saja, Romance, Abby, and Mystery. They're pretty close with eachother

Would be a freak and an akward person around a person he's interested in but would still try to put on a nonchalant act. Despite being 400+ years old in his demon form ( And 25 years old in his human form ) , he is still a silly guy enjoying his life, usually being chaotic and all.
