She was safe only up to the 12 gate.
So she arrived at the gate, told everyone to run. But was too late because that lolita error used her Flower Exploding skill.
Which means, hundreds thousands of sharp flower petals explode in all directions cutting everyone there in pieces.
As you can see at 1 of the scene, her head was on the top right and her hand was on bottom left.

Wait, when did the blonde necromancer girl die? She was fine after the mermaid river thing, wasn't she?
