"What are you doing here still?"
You instinctively tense up and slowly look to behind you.
Oh fuck is tha-
"Well? Are you going to answer me, soldier?" The lieutenant of exorcists states more than asks you. She's standing in between you and the collapsed wall that reveals the outside world; the only real way out of this situation.
Wait, soldier?

He continues on as his lieutenant, Lute, spots something from the sidelines: A single, small sinner rushing towards Adam with a knife.
She yells out, rushing towards him, hoping to all of heaven that she would make it to him in time. "Adam!"
She makes it! Just in time…
Or; Lute dies instead of Adam.

Summary
In the battle for control,
let the hero take the role,
of angel, wrote in code,
the time that we have bode,
to unite, to overthrow.The humans who once fell,
to the underground they dwell.
Only death can forever quell,
a revolt that went to hell.Now the mighty must sweep out despair,
in a world unjust and unfair.
-----------------------------------------------
The fresh memories of revolution remain stuck onto the minds of the underground.Counting drops of blood in their hands, Chara chose a path against the royal family, who now holds them captive. Glimpsing outwards from the castle, Chara sits in royalty, waiting for another storm to hit New Home.
Back in the Ruins, the revolutionary fortress of New Citadel continues to protect its liberty against the will of the monarchy. Yet Clover and Frisk, against the wishes of its leaders, seek to do more: bring justice to the underground. But when one person serves as the judge, jury, and executioner, how fair can justice really be?

Summary
Your life had once been devoted to a single pursuit: study. A PhD in philosophy and a Master’s degree in theogony and social sciences had shaped your years on Earth; thinking and questioning, until you found some synthesis. Death, however, offered no such courtesy.Your afterlife was sweet in its own cruel way, but it denied you the luxury of a similar calling; after all, who would want to listen to Kant when they were already condemned to eternal suffering?
For the past two years, you’ve worked as a bartender at one of the most popular nightclubs in the entertainment district. The job comes with a certain routine comfort, one of its constants being long conversations with Angel Dust every Tuesday and Friday night he’s on shift. Words are exchanged, thoughts drift in and out, until one evening an invitation is casually extended.
An offer to return, if only briefly, to the old habit of thinking. To study redemption.

Summary
But Alastor had been oddly amiable of late, or at least as friendly as he was probably capable of being.... The demon had even started making him coffee on the rare occasion he saw Lucifer was actually up and out of his room early in the morning (Lucifer had a tendency to take his time starting the day). All of this should have clued him in, but he was so focused on functioning at a basic level that it didn’t even register. He should have realized it was all an act, that Alastor was going to want something. That the sinner was trying to fucking manipulate him.
Were he less oblivious, they might have been able to avoid the duck massacre that took place five miserable days ago.
Lucifer really, really needed to start paying more attention.
--
In summary: Alastor makes a particularly cruel decision to convince the devil to heal his chest wound, and Lucifer spirals. Thankfully, he has Charlie and Vaggi for support and, when Alastor is forced to reconsider his actions, things take a surprising, but not unwelcome turn.Bookmarked by Cet0

Summary
Frisk lights up as they slip through the door.
“You- You came!”
Chara sighs, and shuffles over to slam the pretty-people-discount coupon on the counter. What a stupid little slip of paper. But, a discount is a discount, and 75% off is a downright steal with how much people tended up mark up flowers around this time of year.
“Just something to say ‘I miss you’ for Heir’s Return tomorrow.” They mutter.
Or
fluffy charisk bullshit tattoo artist x florist au! with a little angst to taste, and chara and frisk being foils, because what’s more romantic then being each other’s foil characters?

Gunpowder and Cocoa Don’t Mix Very Well by Random_Writer9

Summary
Clover had accepted his fate. Giving up his Soul to free Monsterkind was his final, ultimate act of justice. As his vision blurred, he surrendered to the euphoria, certain his story had ended.
Then his eyes opened. He was back where it all began. Disoriented but alive—only one thought came to mind.
Finding his friends.
—
Flowey had planned to let Clover rest–honest! But as his vine hovered over the Save button, ready to overwrite Clover’s file–a flash of memory made him pause.
It was the run where he lost.
That alone was rare. But it wasn’t the loss that made him pause. No, It was who he saw in it.
Something shifted in his mind and as the gears turned a new plan started to form.
—
Chara hadn’t expected to wake up, not after their plan to free Monsterkind had failed. They especially hadn’t expected to wake up to a Cowboy slaughtering monsters.
They reached for their save, determined to stop him.
—
The timeline has become unstable from the three beings forcefully seizing control over it in rapid succession. The instability grew to be severe enough that the boundaries between past and future have started to blur into an unrecognizable present.
