I Became a Siren and Crashed into Marvel

What do you mean the white-haired girl I turned into isn’t TB, but Observer Zero from Antiochus?! And not in the Azur Lane world, either? It’s freaking Marvel?! (Azur Lane × Marvel. Male-to-female transformation. No System. The author has complicated tastes and is focusing exclusively on the Marvel Cinematic Universe storyline, with no comic or TV-series settings. Please forgive any possible OOC. Thank you.)
