I think you nailed it on that one, Kokonoe really excels at running interference. She has no real footsie tools, bad defensive zoning tools, and overall a pretty weak neutral game, but she can really mess with your opponent to throw off their spacing and zoning, and she has enough ways to do it that you can keep it ambiguous. So far i've generally found it hard to get in on people with her, but at the same time its quite easy to set up enough shit on the screen to make yourself unapproachable. It's an interesting sort of passive aggressive character.
