Magical girls are made of magic power.
Thus, in their transformed state, they don't have various vital points like humans do. No matter the injury, as long as their magic power remains, they can recover quickly.
To truly harm a magical girl, one must aim for her essence; to injure the essence, there are only three ways: wait until the magical girl exhausts her magic power, attack her soul directly, or, if all else fails, attack the source of magic power.
This was precisely the action taken by Yuan.
However, harming the source of magic power is not an easy task. Once the magic source leaves the state of the Heart's Gem and merges with the magical girl, it wanders within the magic body in a semi-illusory state. Its existence is extremely elusive, its position ever-shifting, hardly locatable by normal means.
But in that moment, Emerald Sparrow felt as if her magic source had been locked onto. Fortunately, the enemy did not succeed.
