Lucifer is the second tallest of the seven demon brothers, nearly reaching the height of that of Beelzebub's. He has black hair combed to the right side as well as black eyes with a gradient of red.

Demon Form
In his demon for, Lucifer reveals his two twisted horns and 4 black, fallen angel wings. A black diamond appears on his forehead when taking this form. He wears a two-tailed coat with red and gold peacock feathered designs. Inside, he wears a black waist coat with red design. He wears a black pendant with black and red peacock feathers that is neatly tucked in his waist coat's collar. His pants are of the color black with 2 belt chains hanging on its right side. He wears black leather shoes and contrary to his usual black gloves, he wears red gloves when taking on his demon form.

School Uniform
Lucifer wears the standard RAD Uniform in the proper manner. Unlike other students, his uniform is visibly longer and is enough to cover his knees. Under it, he wears a black shirt with an overlapping mandarin collar and seven (one black, one red, then five black) buttons visible. He also wears a pair of black gloves.

Casual Attire
Lucifer wears a waist coat with a red and black design with complementing white buttons as well as a red long tie tucked in his uniform. The uniform he wears also include white cuffs with one black button for each side. To complete the butler-like attire, he also wears gloves with matching black color. He wears black pants and brown leather shoes and complements the overall attire with a black coat with fur lining and a diamond pattern design in the coat's inner part and wears it on top, resting on his shoulders.

Personality
The eldest and leader of the household, Lucifer presents himself as a calm and intimidating person. With that being said, his brothers would always be seen commenting on how scary Lucifer can be. He is a very strict demon and immediately imposes punishment when his brothers act inappropriately. His sadism is evident in his punishments. Despite being so uptight, he still makes the effort to joke around with his brothers at times, especially when it comes to teasing Mammon. Lucifer has sworn loyalty Diavolo, who is the future king of Devildom and closest friend since thousands of years ago. His brothers, especially Satan would always point out that Lucifer cares for nothing more than Diavolo as well as maintaining his image and reputation.

Being the oldest, Lucifer has proven to be the strongest among the seven demon brothers. This was inevitably shown during the pillow fight in the Demon Castle where he, due to extreme anger, made a hole in one of the beds by throwing non-other than a soft pillow. In Lesson 9, where Satan and Lucifer switched bodies due to touching a magic book at the same time, Lucifer, in Satan's body tried to hit Mammon because of anger however Mammon merely laughed and commented that it is because of him being in Satan's body that his strength has been decreased to that of Satan's. Satan also implied that the brothers were put in order from oldest to youngest by their strength and power with the oldest being the most powerful.

Without being that obvious, Lucifer tends to be over-protective of his brothers. In Lesson 10, seeing that his brother, Satan, was in danger of being attacked by a game version of Cerberus, Lucifer immediately made the attempt to threaten Cerberus claiming that he will do unspecified things if it will lay a finger on his brother. However, his over-protectiveness is sometimes seen to be more suffocating and controlling rather than comforting. This can be seen as evident when Mammon complains about this attitude of Lucifer's to the MC in the chat where he decides to live by himself. Nevertheless, Lucifer only wants the best for his brothers.

Main Story Normal
At the beginning of the game, Lucifer, after being introduced by Diavolo, explains the details on the exchange program to the MC. He claims that if anything were to happen to the MC, it would be their – the student council’s responsibility. He then later introduces several characters as the story progresses.

After the MC attempts to climb the stairs that leads to the attic and the source of mysterious voice she keeps hearing, Lucifer attempted to stop her and claims that it was no place for humans because it is dangerous. He later sends the MC back to her room and further stresses that his words are law.

After the MC had sealed a pact with Leviathan, she goes to his room and hands him the copy of the TSL sound track. Lucifer is taken aback and goes further into as to why he was interested in the sound track in the first place. As he is now distracted, the MC made her way to meet the mysterious voice. Before leaving the room however, Lucifer reminded the MC to not go to the attic which she eventually did.

When uncovered the mystery of Belphegor and the identity of the person in the attic, the MC hears Lucifer and Beelzebub’s discussion about Belphegor and his state in the human world with Beel insisting that Lucifer should forgive their brother. Lucifer questions Beel of which side he would choose to be on, his or Belphegor’s, his twin brother’s however Beel could not reply. The MC discovers Mammon who was also eavesdropping on the two. Mammon states that the brothers were once angels that resided in the Celestial Realm before they fell from grace. Back then, Lucifer loved and was especially fond of Beelzebub, Belphegor, and Lilith however that all changed when they arrived at Devildom. After pledging loyalty to Diavolo, Lucifer would follow his desires no matter what the cost.
