Cocoapowder Fic Ideas I Can't Get To Yet by 3Pleatv

Summary
With the sudden popularity of Early Awakening (which I hugely appreciate, by the by!) I said in the seventh chapter of that fic that I had been debating making a Cocoapowder fanfic for a good bit and decided to settle with fleshing out their dynamic first.
And then the evil thoughts came. "You could write more, you could!!!!! You have the capabilities!"
But y'see, I fear burnout. So, I made a compromise. I'd write snippets of those ideas and leave them here for when I finish with/get distracted from Early Awakening! Short snippets of the ideas I have.
Enjoy!

Summary
For Kanako and Clover, Dune Hill was the place to be. And after both going through many scary encounters during their short time on the surface, it was nice to have a place to call home. Free from whatever was happening in the rest of the region.
However, not all is well. And soon, they're going to find themselves in the middle of something worse than anything they've been through. Something that will test the strength of their friendship, and will have them both be asking themselves so many questions.
Because when your opponent has nothing to lose, everything can change on a dime.This is the second fic in the series, with the story continuing right where the first fic ends. If you haven't read the first one through, I recommend giving it a read since there's a lot of lore that gets carried over. (provided that I don't accidentally retcon everything since it's almost been two years since I started the series)

Eight years before the barrier broke, a human by the name of Melody fell into the Underground. Their journey, as a result of their own actions, would be cut short - in gruesome fashion, no less.

Eight years later, the barrier broke, and Clover would be led by a flowery friend to a most shocking discovery - Melody, alive and breathing.
But with Melody's revival comes with it the return of old wounds - wounds that Melody needs to at least try to help patch up. But Melody came to the Underground for a reason, and as they work to fix the wounds of others, their own scars become apparent.

Summary
Clover's Journey has come to its end.
For most of the Underground, this is a cause for celebration. After all, monsterkind is now only one soul away, and most can live knowing that they will likely be among those who will first step onto freer soil.
A select few, however, see things differently. For them, that human's death provides only unanswerable questions, not peace of mind.How can they honor the memory of such a beautiful yet fleeting life?
How do they go back to living normally after having their previous lives shattered? Is it even right to try and 'go back', or should the pieces be formed into something new?
'Right' and 'wrong' have been revealed to them, but can those things still be found once the light of justice fades?
Creating new light is not so easy. After all:
Sparks cannot be captured
The sun doesn't reach all corners
Stars don't always shine brightly enough
And not all flames can be containedBut perhaps, as the sun gives way to stars and artificial light, so too can the many guide one another along each leg of the journey. They just need to find each other first.

Summary
The Monsters were dead.
They must have been, the Federation of Super Earth had said so; annihilated during the Great Galactic War along with all the other threats to Managed Democracy. So Clover was understandably confused when he set out to find the five missing Cadets only to discover a whole society of Monsters sealed underground.
What’s more, these Monsters were nothing like the tyrannical, Freedom-hating killers history had portrayed them as.
Things just weren't adding up. But why? It’s not like Super Earth would have lied, right?

Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new magical coinhabitants on the surface? How far would they go if they could weaponise their magic?
'Creation, Destruction, Positivity, Negativity, Chaos, Peace, Possibility and Finality
The elements of the multiverse. All are necessary for it to function as intended.
All the pieces, all the gears, all turning as they should.'
