Azazel's Sword.

Jack looked at the card in his hand, and in the first part there was a sword, which looked white and small like a fog.

Azazel's Sword: This sword can only be seen by the user and is faster than light. Eats soul.

Seeing the short description of the sword Jack used the card, a white foggy sword came in front of Jack.

The sword was minuscule, resembling the size of a pen. As Jack observed it hovering in his hand, he attempted to grab it, but it evaded his reach.

"This thing is alive?" Jack was astonished; he looked at the sword that was moving on its own.

Jack tried to grab it a few times but failed.

"So, what's the use of such a sword? If I can't even grab it," Jack murmured. He looked frustrated because of the sword.

As Jack gave up on the sword, the white fog revolved around Jack, constantly moving around.

Jack, giving up the sword, wanted to read some novels, but he remembered he has no phone to read.
