Her liquidization? Well yea it's instant, unless she leaves a delayed effect but she only does that when setting traps on the ground.
"Pff, pff, pff! They fired at least ten times, the muted shots sounding like those of an air gun. In the face of such a merciless onslaught, Liquidizer casually raised her right hand and simply stretched it out in front of her, palm facing front. Then Mikawa's eyes widened in shock, and he imagined that Divider's did, too. Every one of the bullets that had been fired at Liquidizer's body with murderous intent, whether they made impact with her hand or not, melted in midair into lead-colored drops of liquid and fell to the ground"
Raise her hand, bullets get liqified
"Minoru gasped sharply, staring in shock as the liquid quickly solidified again, forming a rocky stalagmite more than nine meters tall. No, it was more like a spear. But they had no time to be surprised, as Liquidizer moved again, using both hands this time. Right as they jumped out of the way, a second spear of rock shot up from the ground, grazing the shell. Then a dark brown torrent of liquid rose up from directly underfoot, clouding Minoru's vision. But of course, the liquefied gravel couldn't scratch the protective shell. Then Minoru suddenly felt his whole body suddenly trapped in place. The spurt of liquefied asphalt and soil had covered the entire shell and then solidified around it, obstructing his movements. "Rrgh…!" Minoru put all his strength into moving his limbs, breaking through the wall of rock. With Yumiko's ability, they used a slide dash to put distance between themselves and Liquidizer. It seemed that the range of her ability to remotely liquefy and solidify the ground was about nine meters"
She can control gravel, asphalt and liquefy it, and then re-solidify it, make earth spears etc
