Sword trails in Unity

Hey guys i was wondering if you could help me with an issue i am having. I am trying to create a sword trail effect Unity. I have created the trails through a particle system and have parented them to the sword of an animated character. However I am unable to find a way to have the trails emit correctly from the sword and correctly follow it’s angle and orientation when they are animated. Below is a video of the issue i am experiencing. If anyone could provide any insight to what i am doing wrong it would be greatly appreciated:

If you are looking just for trails, the better way to achieve them is:

Trail Renderer of unity, like the name says, TRAILS xD, here some documentation bout the component:
