I was getting the feeling that it is very possible to annoy Ken from the air in that match vs Junpei, but that is pure speculation. Also, Ken is a friggin Dragoon. His DP is Jump. I wonder if it can be used to similarly just not exist while ugly, horrible things are happening on the ground. But Koromaru and Ken spend a lot of time absent from the field, which I find funny.
Also, I'm wondering what the properties on hit are of 214C. If it washing machines them down to the ground like Vergil's DP M, that has obvious specific combo application.
