Dark Matter is an uncertain existence, its transformation is not humanoid.
But precisely because of this, after performing this transformation, the Hero can completely reshape an Ether humanoid to fight.
Since that's the case, naturally there's no need for a Mermaid Incarnation to challenge the Corrupted Phoenix.
The primordial Dark Matter is also a Great Demon level transcendent species, coupled with its attributes that counter the Corrupted Phoenix, and the enormous Magic Power provided by the Ancient Hero...
There's not even a need for the Sergeant to sacrifice himself to gain time, in the previous deduction where the Hero fought with all her might but still lost with regret, this time she felt almost no pressure and easily defeated her other self.
Feeling that almost overflowing resentment and shame within her other self, the curve at the Hero's lips couldn't be pressed down for a moment.
