A few years ago, maybe around 2015, I was following this really good manga. Things I remember: had older style of art, the main character was I assume a blonde female knight, maybe she was crossdressing and no one knew or select people knew, can't remember. It was still being translated at the time though I remember it had slow updates. I think it had some sort of reverse harem. The female lead I remember looked very androgynous. Setting is probably historical? I think it had some sort of connection to English knights or churches or pirates or something. I believe it had blood or graphic details. Probably had action or tragedy tags too. Quite vague details I know but ever since I forgot the manga's name, every now and again I remember it and I wish I could read it again. Any sort of idea can help, thank you!
