---Familiar
"Keeeh~?" The bulging Familiar seemed to notice it was being attacked again, as its closest pursuer blitzes forwards with the full extent of her magically-enhanced speed. It pulls its tail close to its body, slowing its movements slightly as it hurtles downwards, wall to its right. When Megumi comes through the barrier, chains swinging in an attempt to capture it, the creature reacts immediately.
Fortunately, this Familiar's single redeeming quality in life was that it was good at escaping. Just as Megumi's first chain approaches from the side, its tail shoots out, suddenly propelling the Familiar to the side. At the same time, another storm of school supplies shoots from its body, flying in the general direction of its new attacker. The high-velocity junk, while virtually harmless, serves as a distraction to cover for its escape.
It's also probably really annoying. Nobody likes being hit with erasers.
Spiraling through the air, the creature fluffs its body up again as it approaches the other alleyway wall, striking it at an angle and fluffing outwards, instantly recovering with another lightning-quick bounce in the other direction. Zigzagging like this, it adjusts its trajectory and continues its jaunt towards the nearby roadway.
And just like that, it was there-
"Kiiiiiiiiiiiiiii~!" The Familiar screeches cheerfully, hurtling past the outskirts of the abandoned area and into populated space once again. With the incredible density of people around the main roadways, it was only natural that immediately upon approaching the street, three humans are sucked into and trapped within the Familiar's flimsy barrier.
It makes its choice, and spirals wildly, hurtling itself towards the nearest human. It was clear what its intention was at this point.
At the same time, Salomea would notice the distinctive sensation of a Witch being almost on top of her. Directly across the street from her, she could probably see the edge of the monster's barrier encroaching on the sidewalk, sucking in a couple of passerby before stopping there, dangerously close to the crowd.
---Minerva
Minerva runs at the height of her ordinary speed, trying to catch up with the blazing speed of Megumi and the Familiar, who already had quite a head start. At her own pace, however, she does manage to catch up with Frederica in time to offer a hasty greeting. "Hi. You must be another girl... I didn't expect there to be so many of us! It's quite jarring, considering I didn't even know there were other Magical Girls until a few minutes ago. Haha..." She smiles at the older girl, and then stares ahead frowning.
"They sure are fast... hey, it looks like the Familiar or whatever is almost at the street. Isn't that bad?" She considers their environment, noting the proximity to large crowds of people, and figuring that it was a bad idea to be fighting a Witch so close to humans. Although, maybe if this was just a Familiar, it wasn't so bad? She didn't know. All she knew was that she was being left behind on her first Witch Hunt ever. And she didn't like it.
