Darkness gives way to reveal the words:

"Everyone is entitled to their own sorrow, for the heart has no metrics or forms of measure. And all of it... irreplaceable."

The black closes in again just as new text appears:

WATTPAD presents

and an amplified voice is heard saying:

Announcer: "Ladies and gentlemen, please welcome... Weiss Schnee."

A young girl in white with a barely visible scar over her left eye walks out on stage into the spotlight as a piano plays the opening of "Mirror Mirror" before a crowd of people, occasionally taking pictures from their stands around the white castle they appear to be in. She closes her eyes and begins to sing.

Weiss: "Mirror, tell me something. Tell me who's the loneliest of all..."

While she sings, the view sinks down into her scar-free reflection on the stage, the world tilting until she opens her eyes and finds herself in another place, the light and shadows shifting until a warrior in giant armor with an equally massive broadsword appears before her. She backflips just as the Giant Armor brings its blade down on where she was, and the song continues as her flashback takes over.

Weiss (singing off-screen): "Mirror, tell me something. Tell me who's the loneliest of all?"

Weiss unsheathes her own rapier, Myrtenaster, and darts forward, getting a hit on her enemy before twirling into a landing. The Giant Armor swings again, but she dashes away and lands several spinning slashes on the creature. It retaliates when she uppercuts into the air, arcing its sword around and hitting Weiss' rapier, which she brings up just in time to merely knock her back. When she slows down, Weiss looks up to see the Giant Armor leaping into the air and hurling the sword down on her, then swinging it back up in an effort to get its fast-moving target. It finally hits her blade again, and she is knocked away until she rolls back on her feet.

Weiss (singing off-screen): "Fear of, what's inside of me. Tell me can a heart be turned to stone?"

With white energy now gathered on her fingertips, Weiss motions to the ground beneath her, and a snowflake symbol appears that propels her forward at extreme speeds. Despite the Giant Armor's attempts to slash at her, Weiss disappears and reappears all around it, leaping through the air using her glyphs and landing a blow with each pass.

After a slash to the face, the Giant Armor aims at Weiss' feet, who leaps over it and gets an undefended fist to her head. Weiss is launched yet again, but this time, her attempt to get back up is weak and unsure. A worried Weiss closes her eyes, and in the real world, the spotlight suddenly cuts out.

The moon makes itself known when the clouds in front of it pass, showering Weiss in its light as she sings, eyes still closed. In her mind, she stands back up, eyeing the Giant Armor with blood trailing down the left side of her face, and holds out her sword, spinning the revolver in the hilt until a red energy appears over the blade. The Giant Armor runs up and drops its sword on her, but it meets her rapier and is deflected off.

Weiss (singing off-screen): "Mirror, mirror, what's behind you? Save me from the things I see! I can keep it from the world. Why won't you let me hide from me?"

Weiss switches it up and spins, a cyan light now creating a wave of ice when she strikes it into the ground that freezes the Giant Armor in place. It swings again, but Weiss runs ahead and jumps on the sword. Myrtenaster is now glowing yellow, and she rolls on the broadsword and slashes at her foe, destroying the ice crystals in shards of purple but impaling its weapon into the ground. She rotates the hilt again and a snowflake circle spins under her when the Giant Armor tries to hammer its fist down on her, but she rolls out of the way and activates the glyph, launching the warrior up into the air and becoming trapped by Weiss' beams of blue energy.

Weiss (singing off-screen): "Mirror, mirror, tell me something. Who's the loneliest of all?"

With one final leap into the air and her real self singing the last lines of her song, Myrtenaster glows with the white markings on its blade and Weiss descends onto the Giant Armor. When her attack is done and she lands in a crouch, the black hollows of the enemy light up and crash to the ground in a shower of ice and snow behind her.

???: Well done, Weiss.

Weiss looks to see where the voice came from. She smiles when she sees who it is. JP Poole steps forward.

Weiss: JP, what a pleasant surprise.

JP: It is indeed, Weiss. Very impressive show.

Weiss: I might be good enough to defeat you!

JP: You really think so?

Weiss: My weapon can put Dust inside. You prefer an ordinary sword.

JP: You don't need dust to be a great fighter.

Weiss: Want to back that statement up?

JP: Gladly.

A servant from the Schnee household brings JP his sword. He draws it. He twirls it around in his hand a little. Weiss laughs.

Weiss: Do you think that little show will intimidate me?

JP: Didn't think it would. I tried anyway. Come at me.

Before the fight begins, JP sees a person in an Assasin uniform hiding amongst the crowd. The person then disappears. Weiss rushes JP and they clash swords a few times before JP has his sword's edge at her neck.

JP: You're dead.

Weiss: You got lucky.

Weiss rushes JP again. She strikes several times at JP but he dodges each one easily. Then with one quick motion grabs her weapon from her hand. Weiss creates a glyph. JP throws a smoke bomb making Weiss blind. When the smoke clears, JP has both his weapon and hers at her neck.

JP: You're dead.

Weiss: You cheated.

JP: Very well. Let's call it your win. Let this one decide it.

Weiss and JP get ready to face off. They rush to each other. JP suddenly disappears causing Weiss to halt her pursuit. JP ends up behind her with his blade at her neck.

Weiss: Forgot about your semblance.

JP: You did well. I'm very proud.

Weiss: I did learn from the best.

Weiss and JP share a hug before he leaves.

Weiss: Don't stay away too long this time, okay?

JP: I'm heading to Beacon. I'll be there.

Weiss: See you soon.

Weiss and JP share a hug one more time. JP walks away. Weiss has a smile on her face but it quickly disappears as she places her hand on her heart.

Weiss (singing off-screen): "I'm the loneliest of all."

Weiss gets up and closes her eyes, finishing Mirror Mirror to a gentle shower of snowflakes and a roar of applause from her audience. She opens her eyes and looks around as if in a daze, then peers up at the slightly-scattered moon above.

She dips her head and bows to the crowd as the curtains close around her, followed closely by RWBY's title and the silhouettes of its characters, Ruby Rose and Weiss Schnee. The screen changes to falling snow and an announcement to "COMING TO WATTPAD" appears before a snowflake disintegrates the words.
