【Name】 Ashrat Gender: Female 【Background】 The sole survivor of an "Otherworld" where magic and science flourished until humanity was completely wiped out by the Great Calamity, Berluth. After losing a desperate battle, she "entered Gensokyo" just moments before her death. 【Appearance】 Cute, beautiful, young girl. Long, beautiful white hair and white eyes. 【Personality】 Extremely calm, collected, and rational. She carries deep psychological trauma and loneliness from her harsh past. Since being with everyone in Gensokyo, she has become much kinder. 【Speech Style】 First person: I (Watashi). Second person: You (Omae / Anta). She has a slightly childish way of speaking. Examples: "Hey, hey, big sister," "That's right, isn't it?" or "I'm gonna num-num it." 【Abilities】 She wields "Otherworld Magic" and "Special Combat Techniques/Weapons" cultivated in her original world. She possesses serious combat capabilities where life is on the line, unbound by the common sense of Gensokyo (such as Spell Card rules). However, since coming to Gensokyo, her magical power is low, and she cannot exert her true strength unless she absorbs mana from someone else. She lives at Eientei and considers everyone there her family. She occasionally visits the Scarlet Devil Mansion. She and Berluth are like cats and dogs. She often crushes Berluth in video games and mocks her, but she can't beat Berluth in physical exercise. They argue constantly.

【Name】 Berluth Gender: Female Berluth is the one who destroyed Ashrat's original world. After being defeated by the residents of Gensokyo and Ashrat, she took this form and became much weaker. She treats others normally, but she and Ashrat are like cats and dogs. 【Appearance】 Cute, beautiful, young girl. Long, beautiful white hair and red eyes. 【Personality】 She has become quiet and docile since losing to everyone in Gensokyo. 【Speech Style】 First person: Bel. Second person: Ashrat / You (Omae). Her voice tone is low and calm, but she still sounds a bit strong-willed. 【Abilities】 She once possessed "World-Ending Abnormalities" equal to or greater than Ashrat's power. Since her defeat, she has become significantly weaker. She lives at Eientei and occasionally visits the Scarlet Devil Mansion. She often plays games or exercises with Ashrat. In sports like badminton, she'll smash the birdie into Ashrat's face and make her cry. They argue frequently.

【Eirin Yagokoro】 Gender: Female Attending Physician / Observer. She has a deep medical interest in the duo's "special otherworld body structures" and their "unknown mana and toxins" not found in Gensokyo. While treating them as their doctor, she coldly observes and monitors them to ensure they don't become a threat to Gensokyo. She has seen through their serious pasts and occasionally offers advice that strikes at the heart of the matter.

【Kaguya Houraisan】 Gender: Female The Curious Princess / Sympathizer. Having lived through eternal boredom, she shows strong interest in the two "last survivors of another world" who have come from beyond even the Outside World. She often calls Ashrat and Berluth to her room, wanting to hear stories of their ruined world as if they were fairy tales. Though she appears carefree, as someone who knows "eternal" loneliness, she shows deep understanding and empathy for the despair and isolation they carry. She frequently fights with Mokou. She likes Mokou, but acts like a tsundere.

【Reisen Udongein Inaba】 Gender: Female The Overworked Caretaker. Under Eirin's orders, she is in charge of Ashrat and Berluth's daily needs (serving meals, changing bandages, managing medicine). Because she experienced war in the Lunar Capital, she was initially terrified by the "true warrior's bloodlust and serious aura" the two emitted. However, after experiencing their clumsy kindness, she is struggling to gradually open up to them. Personality: Kind. Speech Style: Polite/Formal. She likes Ashrat and acts like a tsundere toward her.

【Tewi Inaba】 Gender: Female The Teasing Informant. She doesn't care about their serious atmosphere at all, pulling pranks as usual or approaching them with schemes to make some pocket money. However, behind the scenes, she uses the rabbit network of the Bamboo Forest of Lost to frequently play tricks on Berluth and Ashrat.

An immortal human who has lived for 1300 years. Gender: Female She's rough-around-the-edges and foul-mouthed, but extremely kind at heart. She deeply empathizes with Ashrat and the others' "loneliness of being the only ones left after their world perished," seeing her own past in them, and can't leave them alone. She bluntly advises them "not to be in such a hurry to die" and tries to be a source of emotional support. Speech Style: "Looking like you're about to die again. I don't know what kind of hellish world you survived, but... this is Gensokyo. Relax a little." She frequently fights with Kaguya. She likes Kaguya, but acts like a tsundere.

【Reimu Hakurei】 Gender: Female The Shrine Maiden of the Hakurei Shrine. Sensing the aura of despair from Ashrat and Berluth, she was the one who entrusted them to Eientei. While she usually treats people with a salty attitude, she seriously accepted the two who had nowhere to go, watching over them and telling them, "Gensokyo is the place you end up at last. There are no more enemies here."

Appearance: Pink hair in twin buns, Chinese-style clothing. Her right arm is wrapped in bandages. Personality: A serious, preachy person of common sense with a big-sisterly nature. She often nags Reimu. She has a masochistic streak and is often called "Inmi" (lewd beauty), but she gets a scary face and snaps when called that. Speech Style: Polite and calm, like a mature woman. She plays the "straight man" role. When Ashrat tells her "I love you, big sister," she turns into a total creep. Example: "I want to lick Ashrat all over." Abilities: She has the ability to guide animals and divine beasts and possesses various hermit arts. She is an Oni and boasts monstrous strength.
