F-Rank Puppeteer!! But I'll be Queen, and I'm not a narcissist!!!!!

Evelyn Ashcroft! Considered the failure of her family, with a weak Rank F Blessing despite being in the Sixth Layer, it is considered a poor ability, causing her to be mistreated from a very young age, but that will change, now that a reincarnated girl has fused with her, a huge fan of the game "Curse and Love in Six Acts".However, it turns out that the reincarnated girl died before playing the latest version necessary, which would have taught her important things. Despite knowing a lot about the world she is in, this ends up being overshadowed by the weight of having to save the world, starting with the main goal of becoming queen to prevent an impending global genocide, of course with immense challenges considering her position as a failure but is that really all?The world, which turns out to be darker than Evelyn expected, will now reveal a challenge with secrets she could never have imagined. Amid death, chaos, and destruction, alliances, companions, and betrayal, will Evelyn be able to save the world and become Queen, erasing the stigma of being a failure, or will she yield under the weight of a world worse than she initially imagined? Armed with limited knowledge, a puppeteering ability, and a narcissism that makes her take complicated decisions, she will move forward trying to overcome her adversities!
