What do you do?
You stay back and let the pros handle it
You decide that it may be best to let the magic girls do the fighting. They seem to have experience with it, after all.
At first Siji jumps down, her magic sword swirling with power which gathers, prepared to release as soon as she hits the ground.
But she never hits the ground. Callie swirls her hands around, gathering her own magic, and releasing it toward Siji, which catches her in the air, keeping her trapped suspended.

Siji quickly retaliates by pushing outward with her sword, dismantling the purple magic and landing on the ground.

Rory is quickly up in her face punching her, as Kim twirls around Siji's legs, trying to tackle her. Siji takes the punches, and thrusts the sword toward Kim, who is now within reach.
But Kim is too quick and dodges the sword, before scratching Siji in her face. She screams, but the wound quickly heals.
Kim keeps on scratching, but Siji uses her free hand to grab Kim's throat, strangling her. Rory tries to punch Kim free, but Siji swipes after her with the sword, occupying Rory.
Ophelia jumps forward on her spider legs and Gilda glides over the ground with her slime body. Ophelia spins webs around Siji and Gilda shoots slime after Siji's arms, making her heavier and unable to move much. Lastly Tanya rides around trying to angle herself for her shotgun. Siji uses Kim as a shield against the three.
But this leaves her open to Rory's punch right in the temple of her head, making her drop Kim, who quickly retreats, and stumbles. Ashley, with her larger body, has positioned herself to drop down on her, but before dropping, Ashley expands her body rounder, making her a larger impact and dropping harder.

Siji looks up in terror, unable to stop it. The rest of the magic girls dispels, making room for Ashley, as she drops.
A loud boom. Siji is crushed by Ashley.
You all stand watching.
Ashley slowly deflates, exhausted after expanding all that energy, she deflates completely, until she is comepletely skinny and, well, well proportioned, curvy even.

"Did I get her?" Ashley asks. Siji lies, **** not far from her.
Rory is the first to speak. "Is it over?"
Suddenly, Siji's sword starts glowing against, this time with blue energy. She laughs. "Thanks for all that power!" And stands up. Siji observes her now blue glowing sword, then points it toward Ashley, who is trying to flee, but isn't fast enough. Blue energy shoots out of the sword, hitting Ashley straight on, throwing her away. She screams.

Rory, Kim, Tanya, Ophelia and Gilda all rush Siji.
Callie turns to Stella and Lilly. "Are you gentleladies ever going to chip in?"
Stella the blonde looks confused. "What do you expect me to do?"

But Lilly simply looks annoyed with her petite form and phone in hand. "Fine! But you owe me for this."
"I'll let you burrow as many spells as you want, dear. Now, please save the day." Callie has a way of still sounding calm, even though her words are ****. She runs to join the fighting, shooting purple magic after Siji, who is currently fighting back Ophelia's webs and slicing through Gilda's slime. She swirls her sword wide, so Kim can't get in close and still dodging Rory's blows. All this actions does not allow Tanya to get a good shoot on Siji, which she seems to know.
Lilly looks annoyed at you, before giving her phone to Stella. "Hold this."
"Okay." A startled Stella says.
Lilly stands and suddenly roars out with her lungs fullest capacity. You're surprised by the intensity of the scream from such a petite body.

You look to Stella for an explanation, but she looks just as scared, if not more.
Suddenly, a heat emanates from Lilly, and her body starts growing. Not only that, but horns sprouts from her forehead, wings shoots out from her back, a tail grows out. Her body is growing, expanding, muscles forming and her eyes turns fiery red.

She looks at Stella, who flinches, and looks at you. "I hate this form!" Before yelling louder, her voice now more demonic than before, and flies off toward the fighting.
Siji is somehow holding her own against the rest of them, but when Lilly enters the fray, she grabs Siji by the throat and lift her off from the ground. Siji tries to stab Lilly, but Lilly grabs Siji's wrist with ease and prevents her from swinging it further. Things looks like they turned into your favors, as Lilly lifts Siji high off the ground, but Siji activates another energy burst from her now blue sword, releasing Ashley's energy, which blinds Lilly and makes her drop Siji, who falls back down and picks up the fight with the rest. Siji seems to have become more powerful with the addition of Ashley's powers.
Speaking off, you look toward Ashley, who is currently still thin and curvy, but looking very distressed.
"Are you okay?" You ask.
She looks up at you, terror forming in her eyes. "I-I don't know what's happening inside me."
Suddenly her face seems to bloat up, followed by her body. She is rounding out, which is her power, But this time, it seems to be involuntary. Like her body is acting against her will, Her eyes widens, as she keeps going, keeps bloating, more round than before.

"Ha-has this ever happened before?" You carefully asks.
She shakes her head. "No, never. I have trouble making myself smaller, but I've never had trouble making myself bigger! Ugh." She doesn't stop there. She bloats and becomes more round, in general, not just her proportions, but her whole framing seems to becoming more round overall. Then her stomachs starts turning blue!
"What the hell! I've never done that before!"
"It-it's probably because of that sword! It did something to you!" You try to comfort her. But it doesn't work, Ashley only looks more scared as her stomach keeps turning more and more blue. Not only that, but her skin seems to change, becoming literal material. Becoming...rubber like?

Meanwhile Siji is still fighting the other seven girls. But the blue magic from the sword seems to have become lesser, depleting, used up.
"Keep it up!" Rory screams. "We almost have her! UGH!" Rory takes a hit to the face as she yells this. Siji herself looks more deadlier than ever, sweating and panting, but not giving up as she swings her sword around, wildly. There's no end to the girl's relentless strikes. Siji is outmatched.
In a **** final attack, she uses the rest of the sword's energy to burst outward again, hoping to take as many of them with her as she can.
But Callie was faster, and she pulls all the girls away with her purple magic, saving them from the blast.
With the final energy depleted, Siji's sword beams back to its neutral red glow, though much dimmer. She wobbles, exhausted and spent. "That all you got?" She pushes out between pants.
Kim rushed her, tackles her, Gilda slimes her legs shut, Ophelia webs her hands to the ground and Lilly knocks her out with a punch to the face. Siji is finally down and out.
But at what price. Callie looks back at you, standing above Ashley's transforming form. "What happened to her?"
You shake your head. "I don't know!" And look back down at the blue ball that was Ashley, now lifeless and inanimate.

What now?
