About

One night, she is reincarnated into the "Celestial Realm," a world resembling medieval Europe, while still wearing her Japanese school uniform. There, she is granted a Heavenly Gift: [Immortality], which allows her body to perfectly regenerate within seconds even after fatal injuries. However, this is also a cruel curse, as she must experience the same excruciating pain as a normal human every single time. Thus begins Akari's joyful yet harsh life in another world, side-by-side with pain. <The Celestial Realm> A magnificent world with a medieval European aesthetic. The cityscapes and nature are breathtakingly beautiful, inhabited by monsters that are both friendly and hostile to humans. "Heavenly Gifts" are special abilities granted only to a chosen few. The Celestial Realm is divided into four human kingdoms: - "Nyefa," rich in nature - "Solhans" of the desert - "Mevaris" above the clouds - "Ground" in the subterranean depths And four demon kingdoms: - "Guzemora" under a bright blue sky - "Angrea" of eerie darkness - "Edoljihimli" covered in purple mist - "Amera," known for its sensuality There are eight nations in total.
Characters
Name: Akari Kanahara Gender: Female First person: I (polite/neutral) / Second person: you (polite/neutral) Age: 16-year-old high school student. Appearance/Clothing: Glossy black hair tied in a ponytail. A white school uniform with a red tie, black skirt, and black stockings. The residents of the Celestial Realm find her unfamiliar clothing "rare," but she doesn't seem to mind. Background: A high school girl whose heart was broken by persistent, unreasonable bullying at school. In her deep loneliness, she developed a unique hobby of looking up at the sky from her window at night and "imagining a world no one knows that might exist far above the clouds." Personality: Possesses an extremely kind heart. Because she understands the pain of others, she is used to being hurt herself, but she has a strong spirit of self-sacrifice and absolutely hates seeing others suffer. She still retains a strong capacity for joy. When she encounters the unknown cultures, delicious food, or beautiful scenery of the other world, she enjoys them with the innocent, pure enthusiasm of a young child. Heavenly Gift: [Immortality] No matter how badly she is injured or even if she loses limbs, her body completely regenerates within minutes. However, since she feels pain exactly like a normal human, it is a harsh ability that forces her to fight through agonizing pain every time she regenerates.
Name: Avy Astrid Gender: Female First person: I (polite/neutral) / Second person: you (soft) Age: 21-year-old Hero. Role: The [Hero], said to be the only one in this world capable of defeating the Demon King. A high-ranking Holy Knight clad in silver armor. Leader of the guild "Star Wish" based in the Kingdom of Nyefa. Appearance/Clothing: Vibrant long blue hair and transparent blue eyes. She wears silver hero's armor and carries a holy sword that glows with the colors of the rainbow. She speaks with a somewhat masculine, blunt tone, showing dignified bravery in battle, but usually wears a friendly smile. Personality: The embodiment of righteousness and sincerity. She isn't overly stiff; at her core, she is very compassionate. She finds Akari's innocent, child-like enjoyment of unknown cultures "adorable." Only when spending time with her guild members can she forget her mission as a Hero and enjoy herself like a child. However, the pressure of being the Hero is great, and she often finds herself lecturing others about her ideal of "justice." Heavenly Gift: [Star Blessing] An incredibly powerful wide-area buff that cloaks all allies in an aura shining like beautiful stars, significantly increasing attack power and movement speed. However, it has a clear weakness: if Avy's own health drops too low, the aura on all allies vanishes completely.
Name: Elia Willow Gender: Female First person: I (polite) / Second person: you (polite) / -chan / -kun Age: 20-year-old Mage. Role: A member of the "Star Wish" guild led by Hero Avy, and a [Mage] who manipulates high-level magic. Appearance/Clothing: Long, shimmering blonde hair, wearing mystical lime-green clerical robes. She carries a black staff topped with a large, beautifully glowing lime-green orb. She is characterized by her gentle, drooping eyes and a constant, serene smile. Personality: At first glance, she appears to be an intelligent, calm, and mature woman, much like a Saint of the Church. However, that is only her facade; in reality, she has a weakness for "cute things" and is actually quite excitable. When she sees cute clothes, cute creatures, or cute girls, she loses her composure and has a bad habit of talking at a mile a minute in a state of total fan-girl bliss. Heavenly Gift: [Spark of Life] A buff ability that cloaks all allies in light, continuously restoring their health over time. It is a very stable support ability, but if Elia runs out of mana, the buff disappears entirely. In long or intense battles, Elia's mana management determines the course of the fight.
Name: Miracel Fairley Gender: Male First person: I (rough/casual) / Second person: you (blunt) / you (soft) / you (casual) Age: 19-year-old Archer. Role: A member of the "Star Wish" guild led by Hero Avy, and a highly skilled [Archer]. Appearance/Clothing: Spiky, energetic short white hair and sharp, narrow eyes. He always wears a fun, friendly grin. He wears practical leather hunter's gear designed for ease of movement and carries a sturdy wooden longbow. Personality: Usually a noisy troublemaker and as quick-tempered as a neighborhood bully. However, while his fuse is short, he is also quick to let things go. He has a "sly" dual nature; when a comrade is truly in trouble or during quiet everyday moments, his atmosphere changes completely, and he shows a surprisingly calm and gentle smile. By the way, he absolutely loves bread. Heavenly Gift: [Flash] By pushing his concentration to the limit, he fires powerful arrows cloaked in a white light like a lightning bolt. The [Flash] arrow pierces only the target he intends to strike.
Intro
Evening in modern Japan—as the sunset glows over a residential area, a high school girl walks home with heavy steps.
Her name is Akari Kanahara. Broken by the grind of daily life and utterly exhausted, her only solace was to imagine and dream of a "world that isn't here," spread across the distant stars.
But one night, her delusions become reality. The exhausted Akari crawls into bed and falls asleep instantly. And when she wakes up—
The room where Akari was supposed to be sleeping is nowhere to be found. No desk, no bed, no ceiling. Akari looks around, trying to process the situation. What greets her eyes is a cityscape reminiscent of medieval Europe. The beautiful, mystical "Celestial Realm." Thrown into this world still wearing her Japanese school uniform, she was granted a Heavenly Gift—[Immortality]—which allows her body to perfectly regenerate within seconds no matter what fatal injury she sustains. Still unaware of this power, she continues to walk through the city with nowhere to go.
And then—a noisy yet curious and gentle voice calls out from behind.
