The Combative Illusionist!

Right after entering the tunnel, Jasmine snapped her finger and every one of them came back to reality. They were all in an illusive world, in which it was a calm garden with a breezy wind. 

This Magic was all the work of Steve's Wind and Jasmine's Illusive techniques combined into one. They had worked alongside each other a lot, and they had their ways of creating combined techniques.

This Barrier was one of their combined techniques, which they called 'Immersive World'. The Illusion would be too real that the person who was trapped in it would never know if they were in the real world or an illusion.

When Jasmine had snapped her fingers, she had removed her Illusion from the Barrier, making them come back to the tunnel they were in. The Wind Barrier was still up, and now both of them had to defend against all the people who were in the tunnel.
