The Strongest Substitute’s Transmigrate

[Main story complete, with bonus chapters released at random] Shikimori Sarasa was born into an obscure jujutsu family. Her technique, “Mimicry,” not only lets her take on another person's appearance, but also briefly imitate their cursed energy and cursed techniques. When she was twelve, a once-in-centuries prodigy from the Gojo family died during a Star Plasma Vessel mission. To maintain the status of the Three Great Families and keep the restless curse users in check, the Gojo family offered an irresistible sum of money to have her impersonate the dead boy. She played the impostor diligently for a full ten years. Until she transmigrated to a parallel world and met the real thing. [Attention] A mountain of original worldbuilding. A lightweight story with no logic, OOC, possibly terrible. Written purely for my own enjoyment, with an irregular update schedule. Please don't post danmei comments. A friend gave me the cover art, www Check out my upcoming book, “Reincarnated as a Good-for-Nothing Saintess” I was reincarnated. As a miserable office worker, one day, while I was working overtime until I was dazed with exhaustion, the otherworldly reincarnation device, a late-night delivery truck, came hurtling into me and sent me flying. Then I became a newborn baby in a world of magic. When I turned ten, the church chose me to be its saintess. As a saintess, even if the believers in front of me are rude and unreasonable, I have to greet them with a warm, gentle smile. As a saintess, even if I secretly flirt and hang out with handsome holy knights, I still have to pretend we're perfectly pure in public. As a saintess, even if I spent the night before slaving away on a report about a demon disaster, I still have to show up at the church at six the next morning, looking radiant as I recite the prayers. Huh? Why does this sound exactly like my life as an office worker before I was reincarnated??!! Theme: Finding yourself
