Get unexpected help.

As she felt a sharp touch on her shoulder, she looked to her right and saw a black thing on her shoulder.

"AAAAH!" she screamed and waved her hands, trying to get it off her. If the slime also catches them, they will be doomed! Berry jumped away, but with such clumsiness, she landed on her butt.

"How rude." She heard a voice, but it was neither the voice of Lily nor Amelia. What she saw was a black bird in the air, maybe a raven, but with a violet touch on the endings of its feathers, shining with a purple hue. It landed in the place she was standing just a second ago and looking at her with its two, big eyes. "It seems your friends are in trouble." It pointed with its right wing to the direction of the dark, oily creature. Her friends were too busy fighting for their lives to notice the bird near Berry.

"Get off! Get off!" Lily repeated loudly, still trying to pull out her leg, but the more she pulled, the tighter the grab on her leg was becoming, which lead to the creature pulling her closer and closer to it. The black stuff the slime was made of already reached almost to her knee. Meanwhile, Amelia looked like if someone took a small figurine and poured it all over with some oily substance, making it slowly being covered by it entirely… Berry looked at the situation with despair, not knowing how to help her friends.

"Do you want to help them? The bird asked Berry calmly. She looked at it. Could it help them? It's a bird… but can it really be just a bird? Obviously not, since it speaks, and if it can help them…

"Can… you save them?"

"I cannot save them, but you can. I can give you the power to help. It should be able to defeat it." It turned its head in the monster's direction. "Maybe."

"Power? What are you…" As Berry hesitated, the creature did not. Once more, she heard a loud gurgling sound, and as she looked at her friends, she saw the creature becoming even bigger. A lot. Somehow, the weird oozy liquid was spreading through the entire wooden gym class' floor, slowly touching Lily's butt, which was directly touching the ground.

"Ugh! Disgusting!" she screamed, as it was not only covering the parts of her body closest to the floor, but also slowly began to climb her body.

"S-stop touching me there!" she also heard Amelia's voice, who was almost entirely consumed by the substance, save for her head. If it consumed her entirely, she wouldn't even be able to breathe…

"Alright!" Berry said loudly. "Do something! I want to save them! Help us!"

"The contract is made," The bird said, and took flight above Berry. In a second, Berry's body began to glow with such brightness, she saw nothing, but the sparkling, white light.

"What is…" Berry mumbled under her nose, blinded by sudden radiance, but midway her sentence something took control of her mouth and instead, shouted a different sentence. "Power of purity, heed my call! Unleash my magic! With powers untold and dreams unfurled, I transform into the Magical Girl - Timid Darkness Black!"

…

"W-w-w-what was that!" Berry blushed hard after realizing the words that just came out of her mouth. She was so embarrassed, she totally forgot about her friends being in trouble for a second. "W-w-why did I say that!"

"That's the words you must speak each time you want to transform into a magical girl," The bird explained without a hint of emotion in its voice. "You better hurry and help your friends.

"M-magical girl?" Berry questioned what the bird said, but then she looked down. Her school uniform disappeared, and changed into some kind of cosplay!

Her outfit consisted now out of a fitted bodice dress in a slight purple colour, with a high, white-collar covering her breasts and neck and a swing skirt, which was, in fact, like a swing skirt cut in half, with both pieces holding on two metal accessories on her dress, at her waistline, shaped like a bird feather with a lace trim. It was like cut in half because it left huge gaps on her front and the back, and instead did a bad job of covering her sides, which technically meant that except her spandex-like dress, nothing was actually hiding the shape of her peach butt and almost exposed crotch. The straps of the dress were small, like a bra strap, which made nearly her entire waist visible, together with her armpits. If not for the short skirt, her hips would be clear to see, too.

On her arms, she wore hand-less elbow-length gloves, in the colour of her dress, with both endings also shaped like the raven's feather, with a slight violet touch at its endings.

On her legs, knee-high violet stockings, featured with some delicate laces and two black ribbons, while on her feet she wore white high boots with heels.

Her black hair, normally let down to reach her shoulders, now were made with white ribbon into two, short twin tails, while her fringe was split in two.

"What are those clothes!" she squealed, embarrassed. It was exposing so much! You could see her legs, her waist, and even if it was covering her girls parts, it was so tight you could obviously see the shape of her ample breasts, not to even mention almost nothing was covering her crotch!

"You better hurry, or your friend there is going to lose something." The bird flew onto her head and spoke. As Berry was panicking about her obviously revealing outfit.

"Never mind, if it's just to save my friends, I can wear it for some time!" she scolded herself in her mind. It's not like she was seen by anyone, as both Amelia and Lily were far busier with their problem of being eaten alive.

"W-what can I do now?" She looked up, at the bird, which stretched its neck to talk almost eye to eye with Berry.

"Just imagine you are creating a bolt of magic in your hand, and then shoot it at the Libido. The concentration of your purity will hurt it."

"L-libido?" Berry questioned the name of the monster, but hastily ignored it. She had to save her friends now!

With an open hand pointed at the monster, which was slowly growing in strength, and consuming both of her friends, she closed her eyes and started to create something like an image of a ball in her hand. But no mere ball, but glowing, maybe a little pinkish, since she is supposed to be a magical girl, shooting it fast, at the creature, and then…

*PLUM*

Something did come out of her body! She felt a little shiver travelling through her entire body, which concentrated in the palm of her hand, and with a sudden burst, she shot!

"Magic Bolt!" The words again blurted out of her mouth without her consent, but at least this time they weren't immensely embarrassing. The glowing, pink orb hit the oozy "Libido", as the bird called it, it pierced right through it, while spreading small, glowing particles near it.

*BLURP*

"Hmm, quite effective. You seem to be a superb-ranged type." The bird commented on her shooting. "Keep doing it, and you may free one of your friends from it."

What it said seemed true enough because as soon as the third magical bolt hit the creature, it began to swither so much she could see it was trying to escape again, backing away from the shooter, but it seemed it wasn't giving up just yet, as she saw it began to increase in size even more.

"W-what am I supposed to do?" she tried to ask the bird, but it flew off her in Amelia's direction. Will it help her? Berry hoped so, as she had no idea what was she supposed to do with the creature. For now, she continued to shoot at it, hoping for the best. After an eight shoot, the creature decided it's time to fight back, instead of moving away from Berry, it moved towards her, in quite fast manner.

"Ah!" Berry screamed, when the black creature shot a single tentacle at her direction. She dodged it, somehow, but lost balance again and fell on her butt. "Noo!" The creature took this as an opportunity, and began to slither towards her even faster.

"No way! If it grabs me, won't we all be in big trouble? Can I use some other type of magic, can I punch it?" With no time to think, without even standing up, Berry took her left fist and tried to hit the approaching monster as hard as she could.

"By the power of the pure, ignite my inner light! Transform, Magical Girl Radiance Blue!, and bring forth the power that dwells within!"

In a split second, the monster was pushed so hard it flew off to the other end of the gym class and hit the wall, losing a lot of its black goo on the way there.

"Berry! Are you alright?" she heard from her right and saw Amelia, reaching her hand to her, but not in the towel she wore just minutes ago, but in an entirely different outfit.
