Yeah, I don't think it's smart to challenge Hakumen air to air. You'll get beat almost every time. You're better off slowly making your way in on the ground and jumping in through the air while blocking, to push Hakumen back. Don't fire Spark Bolt as soon as you get hit; hold it so the Hakumen has to be more careful and that will let you get in easier. If he does something dumb you can nail him with Spark Bolt.
