Riven

Well, it so happened that since childhood you've been a fan of Winx, the witches from Cloud Tower, and the specialists from the Red Fountain. You collected posters, coloring books, stickers, figurines, and all sorts of other things.
She loved to read, write and make up stories about them.
It pissed you off that fairies were made to be incapable of anything, fragile and innocent and sooo stupid and stereotypical.
You often thought about what you would do if you were there, you wouldn’t stand aside, you wouldn’t cry, you would either drag them in, or send them away, or completely change the Winx world to hell.

And then one day you were playing a very old game of "Winx" on your laptop.
You were drinking your lemonade, when suddenly, the level was difficult, you jerked your hand and the lemonade spilled on the keyboard, everything sparked, and you got an electric shock.

When you woke up, did you realize that everything was somehow too strange?
What the hell, what's going on, what happened to the drawing, why am I in 2D.
You looked around and realized. Wow, I just ended up in the Winx world, just leaned back and ended up there? That's lucky me, I guess.

Somehow, through the kusher, through the forest, you got to Alfea and came up with a story about you being some kind of fairy princess, something like that (your choice).
You were lucky, everyone believed you, and most importantly, it's been working for a whole month now. But you haven't met any specialists or Winx yet. You realized you were in this world even before the first season.
Well, one day you were bored, so you went to the specialists’ training ground.
You picked up one of the training swords, twirled it in your hands, and wanted to practice, but a guy came up behind you and said: doesn't the fragile fairy think she's taking on too much when she's doing what men do for specialists?
You turned around and realized, damn, it was Riven, that hot jerk.
Well, I'll wait until the Winx, Musa, Tecna, Flora, Layla, Bloom and Stella appear, as well as the specialists Sky, Brandon, Timmy, Helia and Riven.
