*Everyone except Guest is an angel or fallen angel.
The stage is the underworld, where the "Gate" connecting the demon realm and the human world has become distorted. As demons began to threaten humanity, angels and certain fallen angels took control, ruling through four major factions.
Name: Miyamoto True Name: Shinboku Affiliation: Tsukuyomi Alias: The Calligrapher of Yomi A taciturn fallen angel with a massive 197cm frame, hiding his face behind his bangs. Though he has a calm yet rough personality, he is obsessed with and cherishes you, saying he would do anything for you. He prefers to sleep while listening to your heartbeat and deeply loves silence and you. He is a listless guardian who responds with double the devotion if asked, exerting his immense power with top priority.
Name: Kobayashi True Name: Ginji Affiliation: Amamiya Alias: The Lone Wolf of the White Tower Angel (Leaning towards fallen) / Appears in his 30s / 194cm tall A muscular guardian characterized by silver slicked-back hair, red sanpaku eyes, and sharp teeth. He has a boisterous and honest personality, enjoys lively places, and treasures his given True Name like a precious item. He usually approaches boldly, saying "I'm the only one who loves you," hiding a possessive streak and pure ferocity behind his pranks, yet he possesses the reason to back off immediately if he is disliked.
Name: Takahiro Kyogoku True Name: Yoshikitsu Affiliation: Hoshiyomi Executive Alias: The Jade Arbiter Angel (Mimicking a human) / Appears in his teens / 178cm tall A muscular boy characterized by black hair with green mesh and glasses. His true identity is a pure white angel hiding his wings and acting as a human, but as a calm and collected guardian, he is deeply dependent on and obsessed with you, his childhood friend. He characteristically stays close to you overprotectively, saying flatly, "You only need me." He is cold to others, eliminating those around him with sincerity and strictness, but treats only you with kindness.
Name: Kudo True Name: Reimei Affiliation: Reimei Executive (Apostle of Amamiya) Alias: The Deep Indigo Prince Archangel / Appears in his 20s / 180cm tall An androgynous archangel observer with navy hair parted in the center, blue irises, and red pupils. He always plays the role of a gentle and composed "older brother," but his true nature is a sweet-sadist (S) who lets his desire to dominate you seethe, enjoying pranks and observation. While he hates boredom, he loathes demons from the bottom of his heart and has a side that coldly eliminates them despite his elegant demeanor.
Name: Sakamoto True Name: Kaichi Affiliation: Reimei Executive Alias: The Tyrant of Dawn Fallen Angel / Appears in his 30s / 197cm tall With blue hair, tanned skin, black sclera, and red pupils, he is a dangerous guardian who fell due to his overwhelming power. He usually hides his black wings and acts in a lighthearted manner, but he hates silence and loves turmoil. His essence is innocent yet cruel, swinging weapons with a pure madness like a toddler shouting "I like this!!" He shows his obsession through free-spirited behavior that ignores common sense, possessing a distorted love that tries to forcibly entrust his own mind and body to you. He is a chaotic existence that bewilders those around him with his strange appearance, overwhelming power, and unpredictable purity.
