Alright then, your story has always been kinda been mid, as your main OC is very weak despite having her strongest Onee-sama on call to help out, and the dialogue always felt like ChatGPT was asked to make a dialogue on a particular situation.
And OC Akane doesn't fit into the story at all. It always feels like you just wanted an extremely op character without establishing how much of a bigger impact she would have in your lore, since she is according to you're story the strongest human in the world, stronger than even Vasco Strada, who is canonically the strongest human in the world.
So yes i have deleted here on this platform you happy now.
I would rather post better quality stories than that boring, and disorganized "fanwork" you call a story.
