Aethereal Dominance.
One of the five skills granted by the Minths when Yuuta formed a contract with one. It may not be one of the most useful ones but in that certain situation, it was the only thing that would work. Aethereal Dominance allows one to tap into the innate power of the Minths— which is to have dominance over someone and enter into their bodies, gaining full control over their thoughts and actions. It was quite a scary skill but it has its own fair share of pros and cons as well.
