Writing New Inuyasha Idea

[Sir Gawain]

I've been working on rough drafts of a new idea for the Inuyasha storyline. Although it doesn't take place alngside the stars of Inuyasha, they are seen several times, but not mentioned by name.
First, I'd like someone to review my cast of characters:
Shike (She K)- The main character. She follows Kagome to the warring states era. However, she has a secret that makes her a prime target for demons. She turns into a wolf demon uring the full moon.
Adoko (Aid O Ko)- Used to be a guardian of Hell. Shike frees him and he becomes her servant, him doing most of the killing throught the story. He's a bull/minotaur demon.
Six Dragons- These dragons are all named after Japanesse weapons. They also each have an element. Kodachi, thunder. Katana, fire. Kotetsu, Nature. Masmune, poison. Shuriken, Yin. Judo, Yang.

That's all of the important things. After I get some reviews I'll post the basic overlay of the story. Please tell me what you think! I don't care if it's brutal!

The dragons aren't really spirits. They're just living creatures. Each of them is represented by a color. Blue, red, purple, black, green, and white. The whole reason for them being there is the story. If they all use their energy on each other's enegy, they create a new fist sized diamond called the Dragon's Heart. There really aren't any main bad guys except for Adoko's old partner, the serpent guardian. But they do run in to Naraku a few times. He eventually kidnaps Shike because of her demon transformation.
Other than that, the only baddies are random demons. You can give me an idea if you want to get some credit if anyone really likes the story.
