[Western Crossover] An Angel's Heart

[I struggled onward, chasing a faint illusion, only to gain nothing in the end] She always felt pain, because she knew that some things in this world could never be achieved, no matter how hard she tried. She was neither god nor demon, and her love and hatred were not pure enough, so she suffered. Laetitia, leader of the angelic army, was given a new life and a reason to exist by an ineffable, mighty being from the multiverse. She was willing to become its knight. The purpose of her existence was to give everything to its experiments and advance civilization. If civilization did not progress, she would shatter anything that stood in its way, even if it was something good. - I encountered the Light and came to love. Without the Light, I would sink into darkness; without love, my heart would be utterly desolate. Who can walk beside me in the Holy Light? - The heroine is impossibly cool, and belongs to the Lawful Neutral alignment. The War installment of the Four Horsemen of the Apocalypse series. P.S. The heroine is Thanos's younger sister. If you find that off-putting, feel free to leave. Let's give each other some peace and quiet.
