Nathalia didn't sigh or frown when she realized she was in an adverse situation. She just thought clearly and calmly.
If her opponent's advantage was her speed, the Elf just needed to get faster, and for that, she needed her spear.
Kaga slowly walked towards Nathalia while snapping her stiff shoulders from waiting so long. The boxer had a smile on her face, and when she breathed in again to use <Lethal Velocity>, Nathalia already knew she would advance.
'Come on! I'm ready for you!' Nathalia thought excitedly.
Again, Kaga surged in front of Nathalia at an absurd speed and tried to punch her before the Elf could react, but Nathalia was also somewhat fast and had good notions of dodging.
All it took was for Nathalia to move her spine back slightly for the powerful punch from the boxer to hit the air. Kaga's punch was so fast that it made a loud noise as if the sound barrier itself was being broken.
