I didn't say you could leave

Although Sienna is a girl, she is indeed a powerful mage, mastering three types of magic: sensory magic, music magic, and healing magic. 

With her sensory magic, she detected Alex's disappearance in an instant and swung her whip towards the predicted landing spot of Alex.

Sensory magic also allows her to detect elemental fluctuations in the air, so Sienna was confident that Alex would appear at that location. 

Sure enough, Alex materialized there, but now she held a scythe in her hand, blocking Sienna's preemptive strike.

"Are you ready to meet your death?"

!!!

Three exclamation marks appeared above Sienna's head, shocked by Alex's incredible speed. 

Ice pillars surged towards Sienna, who responded by cracking her whip, shattering the ice with the sound waves it emitted.
