Lord of Mysteries: I'm a Sealed Angel

Waking up as Olivia wasn't just a gender swap; it was a cosmic joke. I, Lin Xiao, an ordinary guy, am now a Sequence 2 Angel—a literal sealed artifact of the Goddess of Night, trapped in the deepest part of her holy church in the perilous Lord of Mysteries world. Powerless, imprisoned, and surrounded by seals designed to contain beings beyond comprehension, my future seems bleak. But I remember. Every plot twist, every secret, every divine entity in this terrifying world. My knowledge of the future is my only weapon. With a cunning mind and a desperate prayer, I'll join the nascent Tarot Club, manipulate the 'Fool,' and leverage every scrap of meta-knowledge. My first target: the legendary Wishing Magic Lamp, and a quick profit from selling the very seals that once bound me. Will this cross-gender, meta-gaming angel rewrite her fate, or will the terrifying truth of this world consume her before she can even escape her gilded cage?
