Vayu is fighting against a field boss that is called the Desert Fiend Fox. It is a monster that uses manipulation of its pheromones to control or seduce anything in its area of effect. It also has six tails that is able to stretch which also hits like a truck.
Each of the tails can also be used as a way to defend when all curl up. This way of attack is what the Desert Fiend Fox uses on order to destroy any enemy it cannot hypnotize with its pheromones. Vayu made sure to always circulate the air near him so that his nose does not pick up on the scent of the Desert Fiend Fox.
He would then use the air currents to guide him in where he needs to attack as his fighting style continued to evolve. If one were to say that he is a swordsman that is one with the wind then that is the perfect description of him. Vayu is also making use of his ability to read the change in air flow to perfectly dodge all the attacks of the tails.
A bit busy today. Will have more chaps tomorrow
