Nacht is overjoyed at the prospect and, over a short time, successfully binds four devils- Gimodelo, Slotos, Plumede, and Walgner-and masters their powers. When Nacht turns 18 years old, his parents tell him of the family's history of studying devils and bring to the underground training chamber. Morgen also befriends Yami and encourages Nacht to join as well, but Nacht refuses. Later that year, Morgen and Yami join the Grey Deer squad of the Magic Knights. The two get along and have fun committing petty crimes together. After the twins turn 15 years old and receive their grimoires, Nacht hears about a foreigner with weird magic so he investigates and meets Yami Sukehiro. Nacht and his twin, Morgen, were born to House Faust. Nacht and Yami run around, committing crimes together. This belief likely stems from his inability to forgive himself for his actions. Nacht believes that doing good does not make up for past wrongs. He has a very specific ideology about what determines good and bad something is only good if it is good from the start, where as something bad that becomes good, though a pleasant surprise, is still ultimately bad. He is also unafraid of expressing his dislike of all the Magic Knight captains to their faces. Nacht is not shy about expressing whether or not he likes someone. He believes that losing a fight is the loser's own fault and considers losers to be idiots. He knows that Asta has no chance of saving Yami from the Dark Triad alone. Nacht has a scar on his left wrist from where Lucifugus' relic was destroyed.
Plumede's horns form at his temples and the markings extend down the sides of his head and across his cheekbones. Gimodelo's horns form on his forehead and the markings extend down over his eyes to his cheeks. When using the power of one of his devils, Nacht sprouts a pair of black horns, and black markings extend out from the horns toward his face. At 18 years, he wears a dark-colored, long-sleeved shirt with a deep v-cut, a pair of dark-colored, fingerless gloves with fur on the hems, a covering on his right thumb, and dark-colored pants, as well as dark-colored, knee-high boots. His dark-colored pants are tucked into light-colored boots, which have sets of four belts.Īs a child, Nacht has black hair like his twin, but by the time he is 15 years old, he has dyed his hair blond. His grimoire pouch has the Black Bull's insignia. He has four blue belts around his waist and another pair of belts below with his grimoire pouch hanging off the left. Nacht wears a dark-colored jacket with four buttons on the high collar. He wears a plain cord necklace, from which hang four devil-connected relics. He has long, black hair that is pulled up into a high ponytail, and light blue eyes. Nacht is a young man with fair skin and a soft facial structure.
