After waking up, he discovers that he has entered a mindless romance game for women and, by a cruel twist of fate, become the disposable younger brother of the villainous noblewoman. Faced with a miserable future in which the supposedly invincible power of true love might lead the Crown Prince to kill him, a corrupted character might murder his sister, and his whole family might be exiled to the frontier, he turns around and plunges into the mysterious world of magic. Pale blue flames burn atop pallid bones, while truth lies hidden behind layer upon layer of mist. Beneath the chaotic, lawless curtain of darkness lurk orderly, mysterious laws. Bathed in the witness-light of steam and arcane arts, a traveler from another world embarks on a homeward journey from which there is no return. Who is chuckling behind the mask? In the night, the stars' sparks endure. When the key called curiosity opens the magic box, will what emerges be disaster or hope? * Inspired by Japanese reincarnation-as-a-villainess light novels. (It should be a Western fantasy story wearing a light-novel outfit, with a touch of faux-Cthulhu style.) * Please do not apply any character's worldview to real life. * Includes unverified scientific conjectures. Theme: I think, therefore I am.
