As force started mounting on his foot being held by the mysterious thing, he instinctively slashed the sword down without even adding his qi onto it.
Cling
A sharp metallic sound echoed.
Noctis looked down finally to see a grey tube like object wrapped around his foot with a slash on it, cutting it half open as blue liquid, roughly the same colour as the sea, flowed out of it.
At the same time he heard a scream from his side.
Noctis looked towards Cora in alarm, only to see her missing, her scream still being heard from above his head.
Jerking his head upwards he saw Cora in the grip of the same grey rope-like thing, one end holding Cora and another going into the sea.
In a split second as he saw Cora in the air, the tube started shrinking back into water with speed, dragging her with it.
