Nyx the Demon Girl [OP MC, Academy]

Nyx was supposed to be a game character. Instead, she was summoned. While soloing a late-game boss in Asteroth Online, a freelance graphic designer finds herself pulled into another world, manifested not as a hero, but as her own level 198 VRMMORPG avatar: Nyx, a [High Demon] with power far beyond what this world should allow. Her summoners are not kings or archmages or cultists, but three noble girls armed with a forbidden grimoire. To protect them—and herself—Nyx agrees to a lie. Disguised as a minor noble student at the Royal Academy, Nyx just wants to keep her head down. Unfortunately, the Academy is a minefield of tropes. Between avoiding the Crown Prince’s sudden interest, dodging the Villainess schemes, and babysitting her summoners through dungeons they are woefully under-leveled for, Nyx realizes she’s trapped in a narrative web. She has the power to shatter the world, but using it would ruin her cover. Can she survive the "plot" without accidentally becoming the Demon King everyone fears? What to expect: - OP protagonist - Noble society, etiquette, and academy politics (heavily-otome plot!) - Very light on LitRPG elements
