Particle system with soul/ki behind ball

Hello,
I am trying to create soul/ki effect behind ball like in picture.
Soul/Ki is black in picture.
Ball is white in picture.
Background is gray in picture.
Arrow is blue in picture and show that ball is in move.

On left side is when ball is not moving.
On right side is when ball is in move (physical based move).

I want to soul/ki always face camera and be behind ball.

I’m trying with smoke/fire particles but it’s not good.

Maybe someone have idea how to create this?

Thanks.
