Who was this person? Suddenly out of nowhere, only a second after Liv had regained her stance and readied herself for her next course of action, some boy had boldly leaped from between the buildings, ran under the spider, and now stood in front of her. Her fist conclusion was that this was another guardian who'd survived the spiders first attack, but then again she couldn't recall seeing this person in the group from earlier. When he showed clear signs of housing a mana, she grew slightly suspicious, however her suspicions would have to wait to be studied later. At the moment the smoke bombs that had been thrown by Lily had cleared up and the spider now had a clear view of the both of them.
It begun to charge and Liv raised her weapon a few inches and prepared to charge as well, that was until until the strange boy had stepped up and released a strong surge of power from his fist, stopping the mana-eater in it's tracks. Her hair and clothes ruffled as the wind from his, say, shield blew out the sides. Whether this person was someone who had been on the mission with them or not didn't matter to her now. With another person fighting, they might stand a chance.
"You there! Run before its too late!"
Livs eyes widened just slightly, but they once again returned to their mostly stoic appearance after she realized what was about to happen. Of course there was no way he could hold it off for much longer. "How annoying", she thought to herself, feeling kind of angry with him. She could run off and save herself, yeah, but if he tried to step away he wouldn't nearly have enough time to escape the spider before it would ram into him. She resisted the urge to point her gun at him and mutter something like 'idiot', or 'shut up', and instead leaned forward.
"Hold it there.", she said dully before pushing off with her left food and begun to dash forward, sword in both hands and ready to be swung. It was clear to her now. The monsters weakness was obviously it's legs. Without them it wouldn't be able to move and it would be helpless. She of course could not remove all of them, but she new Lily was above watching and she'd spotted another one of their guardians not far off behind the spider. She could yell to them and explain what her plan was, but this mana-eater was intelligent and could not be underestimated in such a way.
All she could do was hope that the other two would catch on as she curved around the right side and aimed for the front leg. There was the loud crackling noise of electricity as she pushed more of her power into the blade of her sword, the light flickering and lines of lightening thickening and shocking the ground around her. With a swift swing she sliced the blade through the middle of the spiders front leg. Maybe it's body was made of almost impenetrable armor, but it's legs didn't seem to be so lucky.
Not knowing whether or not the stranger could keep the spider still fro much longer, she called out Lily's name, though her name was all she called out and she knew she couldn't yell loud enough for the white-haired boy to hear her.
"The legs!", she wanted to shout, but instead kept quiet and instead leaped to the side to avoid the swing of the second leg that reached for her, but moved too slowly. "Aim for it's legs!"
