@DecemberAzure Oh, okay. But, maybe, can you please watch some cutscenes of JJK Phantom Parade in YouTube? JJK Phantom Parade shows a lot more depth to the JJK characters and you won't regret it!
Also, what did you think about the story idea about Nyx? I know it needs more information but I was thinking you can fill in the plot/story telling to since you're going to write/tell how it's going to happen.
Though, I can give you an idea of how Nyx's personality and the body she's going to make for herself since she going to earth. Okay, here we go. Nyx's personality: Authoritative, protective, and independent. These are the personality people think/believe she has, which is true but that's not all. She's childish at times(almost like gojo's but it's endearing), curious(since she was sealed away, she hasn't seen the world change), kind, a little naive/innocent and dense, adventurers, positive, and other things you want to put.
Nyx's body is durable but fragile somewhat at the same(in a way). Nyx's can change her body into three forms: a child, teenager, and adult(like Nezuko). Her child and teenager forms she always use to save up her power. Nyx's adult form is were she unleash her somewhat full power but if she unleash her full power for too long, she starts to crumble(though she can use her adult form without using her full power but she likes using her child and teenager forms a lot).
Like the ideas for Nyx's so far? I tried ( ̄ー ̄). And hope you're having great day!
