TLDR: Kanade Yoisaki from HATSUNE MIKU: COLORFUL STAGE!!

No clue about anything else either I'm out of reasonable guesses LOL

Some of my guesses probably might have been a little dumb because as I've said i'm not that brain rotted by pjsk and i don't have the greatest grasp on these characters either but I think they're Quirky And Cool...

as for cards I have no actual guesses but can we get a N25 Miku 4 star I think that she deserves it cause N25 Miku is Awesome

As for the song, although from that one little teaser we got it does sound pretty playful I swear there's something about it that feels sorta sad - The imagery of the teaser itself is also really curious since it's all mirrors and portraits(?? unsure). So like, Whatever that means.

+ Healthier kanade would be Pretty Cool... Sad Wet Cat but no longer Sad And Wet,,,

OR it'll just be more Kanade Memories Ooohhh

I really hope they start actually doing something more meaningful with her rather than what they've been doing with her events since i really like her character and would like her to be expanded a bit more tbh

Thing is, kanade's character feels very stagnant compared to the rest of niigo - most likely on purpose due to their problems going extremely deep, which is probably why she'll be the last pillar to fall out of them all.

I think the event itself is going to start building up some type of Kanade-based arc, due to all of the niigo members alredy having resolved their conflicts to atleast some degree - While Kanade as a character still feels very stuck on her own problems to some degree

I'm not exactly the most invested in this game so my guesses are probably rlly scuffed, but...
