[Blood Blockade Battlefront] Flame Knight

A manga artist dreams of cosplaying with her teammates from the secret society she belongs to. ---Warnings--- A romantic Blood Blockade Battlefront fanfic, with an original older female lead. The female lead has an ex-boyfriend, and the events surrounding him will remain tangled up in the story for a long time. If you're very particular about your ship, please proceed with caution qwq I watched the anime first, so the plot is a bit all over the place, and there may be speculation and omissions. I haven't researched the real-world background, so the setting is a little flimsy. There may be a Mary Sue and out-of-character moments, so please forgive me _(:з"∠)_
