Yuki Sakurai is a teenager with a mysterious ability. He was abandoned at birth near the Asahi orphanage. Because of that event, Yuki strives for independence. He hates being a burden to anyone near him, but at the same time, he is afraid of being abandoned. Moreover, ever since he can remember, he has had a strange empathic ability that when he touches others, he can feel their emotions, and generate a very powerful wave of pure yellow light that instantaneously purifies everything in its path which is why he is known as "God's Light." Unable to control them, he's often made insensitive blunders in the past. He later meets a mysterious yet beautiful stranger who saves his life, but for some reason he feels like they've met before. While death looms and his ability gets stronger and stronger, a man who claims to be his older brother suddenly appears, which raises the question: "What will Yuki do when he learns the whole truth of his previous life?"

• Yuki Giou (祇王 夕月, Giō Yuki) Sakurai (桜井) • Sōichirō Hoshi • Yuki is a high school freshman who bears Kami no Hikari (神の光, 'The Light of God'). Abandoned at birth by his mother, Mizuki, he grows up in Asahi Orphanage. Physical contact with those in emotional distress allows him to read their emotions and see their past, an ability that causes him great suffering. He feels an odd nostalgia for Zess and often relies on him. After moving to the Twilight Mansion, he becomes known as Giou Yuki. He is the most important member of the Giou Clan and is considered the master of the Zweilts. His special technique, Hallowed Wall, creates a protective yellow barrier, though it demands significant focus and mystical energy. Yuki possesses the ability to bear the pain and "sins" of others, healing fellow Zweilts by taking their injuries upon himself, often resulting in his collapse for days. Yuki has been reincarnated many times, with his current life being his first as a male. • Luka Crosszeria (ルカクロスゼリア, Ruka Kurosuzeria) Zess (ゼス, Zesu) • Takahiro Sakurai • A Duras demon with silver eyes and black hair, Luka has protected Yuki from the shadows for 15 years. Though his true age is unknown, he appears as a college student. Reserved and indifferent, his demeanor softens only around Yuki. A descendant of the "sinner" clan Crosszeria, Luka is a powerful Opasts known as "Bloody Cross" for his unique red Brand Zess. He wields a large black sword capable of powerful magic and commands the dragon familiar Sodom. Once bound by a painful blood contract to the demon king, Luka abandoned that position after meeting Yuki. He now fights alongside the Giou Clan, considered a traitor by other Duras, and is completely devoted to Yuki.

• Tsukumo Murasame (叢雨九十九, Murasame Tsukumo) • Jun Fukuyama • A bearer of Kami no Mimi (神の耳, 'God's Ears'), Hose is a high school boy and a Zweilt Guardian of the Giou Clan.

Hose is deeply protective of his older sister, Toko, and the two are constant companions. • Toko Murasame (叢雨十瑚, Murasame Tōko) • Marina Inoue • Tsukumo's older sister, Yuki's relative and also a Zweilt guardian. Her ring produces a huge sword called Eon (Eternity). She attends the same high school as her brother, where their closeness make all the girls jealous of her. She is very fond of Yuki (whom she calls Yuki-chan), telling him that "He is a person who is too kind for his own good" and asking him to refer to her in a more close way (Tōko-chan) instead of calling her Tōko-san. She is the guardian that most interacts with Luka, and sometimes blushes when she is near him, because in her past life, Tōko had a lover who resembled Luka. • Hotsuma Renjou (蓮城焔椎真, Renjou Hotsuma) • Daisuke Ono • A bearer of Kami no Koe (神の声, 'God's Voice'), Hotsuma is a Zweilt guardian whose gift manifests as fire, which he controls with volatile results. His fiery abilities caused an incident in his youth, leading to profound isolation. He carries deep guilt over a scar his childhood friend, Shuusei, received while stopping a subsequent suicide attempt. Hotsuma's ring produces a curvy blade named Masterstroke. Initially distrustful of Yuki, he gradually forms a bond with him, finding his fiery emotions can be calmed in Yuki's presence. • Shūsei Usui (碓氷 愁生, Usui Shūsei) • Mamoru Miyano • A bearer of Kami no Me (神の目, 'God's Eyes'), Shuusei is a Zweilt guardian and Hotsuma's childhood friend. He assists the police with his sixth sense and fights using crystal balls for support and a pair of short swords named Kurai Kurou. Quiet and sensitive, Shuusei has a notably small appetite. He later disappears, feeling his purpose was fulfilled after Yuki helps Hotsuma overcome his fears. After being kidnapped by Ashley and falling into a deep sleep, Hotsuma uses his Kami no Koe to command Shuusei to live, reviving him. • Kuroto Hourai (蓬莱 黒刀, Hourai Kuroto) • Hiroshi Kamiya • A professional shogi prodigy, he is quiet and serious by nature. He commits fully to his decisions, even if it means leaving behind something he loves, such as his shogi career, which he discovered after being taken in by Senshirou's grandfather.

• Takashiro Giou (祇王 天白, Giou Takashiro) • Takehito Koyasu • Takashiro Giou is the head of the Giou clan, initially introduced as Yuki's half-brother. He has lived for over a thousand years, having performed a forbidden ritual to house a Duras within his body, which grants him rapid healing and exempts him from reincarnation. He possesses a red grimoire known as the Book of Solomon. Takashiro is responsible for the continual reincarnation of Yuki and the Zweilts to fight the war against Reiga, a former friend, believing victory requires significant sacrifices. The Duras within him is later revealed to be a fragment of King Lucifer. • Tachibana Giou (祇王 橘, Giou Tachibana) • Shinichiro Miki • Tachibana is the curator at the Twilight Mansion and a member of the Giou clan.

Isuzu is known for passing out for various days from lack of sleep, which is caused by his sleepless and restless nights of researching the subject of Duras.

• Kanata Wakamiya (若宮奏多, Wakamiya Kanata) • Akira Ishida • Kanata is a childhood friend of Yuki, having grown up with him in the same orphanage. He carries the "Book of Raziel" and frequently opposes Yuki's residence at the Twilight Mansion. Kanata is later revealed to be the human reincarnation of Giou Reiga.

His memories and power as Reiga were sealed until his human body matured enough to withstand them. • Yuki Giou (ユキ(前世)) • Yukana • A supremely powerful Zweilt, the female incarnation of Yuki fell deeply in love with the Duras Luka, an event that precipitated Luka's betrayal of the demon king.

Although he serves the entire residence and its guests, his greatest loyalty resides with Takashiro.

His admiration is palpable throughout the story, but he has openly admitted that Takashiro is the one he loves. • Aya Kureha (呉羽 綾, Kureha Aya) • Sayuri Yahagi • Although not much is yet revealed about Aya, Aya takes care of those in the Twilight Mansion. She is also the younger sister of Fuyutoki. • Katsumi Tooma (遠間 克己, Tooma Katsumi) • Nobuhiko Okamoto • Katsumi is a full time cook at "Twilight Mansion" and a world-class chef.

His abilities were unknown. • Sodom (ソドム, Sodomu) • Momoko Ishikawa • Luka's pet dragon who often serves as one of the series comic reliefs. He has a more larger and realistic appearance of a dragon when fighting, but is often shown in his chibi form which has a split resemblance to Pikachu from the Pokémon franchise.

After Kuroto was reincarnated and put into the custody of Senshirou's grandfather for Zweilt training, Cadenza returned to kill Kuroto. The old man died protecting Senshirou and Kuroto, who both now want Cadenza dead. He is also known as the "Master Killer" due to his reputation of turning on the person who summons him. • Luze (ルゼ, Ruze) • Shinnosuke Tachibana • He is Luka's younger fraternal twin brother, distinguished by his amethyst eyes and longer hair worn in a ponytail. As a half-Duras, he relates to Reiga Giou and resents Luka for his betrayal of the Duras and for further disgracing the Crosszeria Clan through his romance with the female Yuki. • Jekyll (ジキル, Jikiru) Hyde (ハイド, Haido) • Identical twin brothers who fought as a coordinated team, Jekyll and Hyde were both killed in the same battle. After Jekyll's death, Elegy allowed Hyde to drink her blood. This act granted him a power boost, enabling him to create a copy of himself to fight alongside as if Jekyll were still present.
