You're here and that's good (Gratsu)

Hello there this is in fact the 2nd book of I won't let you go pls enjoy now here's a hopefully intriguing description.
Remember Rogue's physcotic shadow? Yeah? Good.
What if Gray had something simaliar.
Not specifically a shadow but just maybe some form of spirit.
Can Gray control it or will people get hurt?
Can Natsu save him before it consumes him?
