Cross flair intro
The trailer starts with a ringing school bell before zooming out of a picturesque Japanese school classroom, with Pyra, Female Villager, Daisy, and Joker, all in school uniforms, walking out of class. A new door opens and the four school classmates walk into a new room, where they sit down and relax, waiting for a fifth and final member to join them. After a few interactions between the characters, Pyra freezes up as her eyes flat-out glitch a little bit before she snaps out of it just as quickly, cradling her head. Suddenly, they notice the entire room being eaten away by pink energy until eventually, the four are suddenly plunged inside a large, dark red void. The quartet, unnerved by all this, gets a good look at their surroundings before a small giggle is heard.
"Oh. There you are! Sorry that I'm late, I had a few things to handle."
They whirl in the direction of the voice, where they see a single pair of glowing green lights staring down at them. Pyra manages to muster enough courage to summon her Aegis sword, which prompts Joker to take out his knife and gun. Villager and Daisy, still visibly nervous, manage to prepare for battle nonetheless.
"Hey, now, no need to be so hostile," said the young voice, her playfulness evident. "I'm just the same girl I always was. Although...you four aren't the ones I know."
As the voice monologues, the lights get closer until a young, feminine silhouette begins to form from within the void.
"Still, I can't be too picky. Having to be cooped up in my own game gets a bit boring after a while. I wanna see more. I wanna do more."
The silhouette then reveals itself as the shine in their eyes dies down, revealing...an inconspicuous-looking high-school girl with a white ribbon on her ponytail. Her smile then loses any form of innocence it had before as it now becomes more...impish.
"Now then, let's get this club in session!"
MONIKA Books A Spot!?
We then see gameplay of Monika starting off in the "Literature Club Room" stage, where she showcases a moveset involving tampering with the source code of Smash and changing it to suit her needs. Relocating platforms, changing stage properties, and even adding new blast lines. The trailer abruptly ends as she activates her Final Smash before the viewer is treated to one-on-one time with Monika.
"Well...that was fun, wasn't it? I'm in Smash now. Bet you didn't expect that. Though there will be some of you that will be leaving with sour tastes in your mouths, that's to be expected. giggle...I look forward to be on your Switches pretty soon. Goodbye for now, I'll remember you all when Sakurai hosts my presentation. Tune in~"
