Watching Gachiakuta makes me wanna write a fic but I can't, I have too many already, noooooooo
I already have the idea.
Mc is a part of the universe so, no isekai but the first few chapters will be focused on her life and how she gains her virtual instrument before she joins the cleaners. Then it will line with building relationships with everyone before it falls into the plot of the series and Rudo coming down to the ground.
Her virtual instrument is an old motorcycle she uses to drive but for a fight, she can transform it into a scythe. How that is possible? I have no clue for now but this is my idea. I'll come to it in the future when I feel like writing it.
