Interstellar Sentinel + Mary Sue with a universally adored but one-sided love + No romantic pairing but some ambiguous feelings + No BL but includes a small amount of GL + A female protagonist who grows through character development, not a lighthearted story at the beginning + Dark and villainous (not a delicate and kind female lead, not a traditional strong female lead, please do not read if you mind).

"Everything I've done is a vote for the world I want."
