Summary
Alexander Koskinen is not a perfect man, but he’s lived his life to what he believes is the best he could. But after falling into the underground, that belief is shattered, and the guilt that has built up over the years has come crashing down, a weight he can no longer bear alone like he has for so long. Now it’s up to Chujin Ketsukane, patriarch of the Ketsukane household, to help pick up the pieces of this lost soul’s life, lest he be consumed by the past that’s been haunting him for all these years.

A contribution of oneshots for an Undertale Yellow AU from UTY Sub-Reddit called "Mamadillo" made by u/CandidCriticism1730
To put it simply, at one point Dina (The Wild East's Saloon Owner) adopts Clover. That's it, and I love it to the bottom of my heart.
And here I am, making a chapter whenever I can to contribute more fluffiness, or angstfest :V

Dragon Blaz(ing) 2: Tragedy In Blue by altruisticTerror, TGClmao
Fandoms: Deltarune (Video Game)
08 Nov 2025
Tags
Summary
I uncovered a mysterious Dragon Blazers 2 ROM hack on an old, obscure forum. To help everyone get the full experience, I've decided to novelise it! Hopefully this makes my exploration make more sense!
Cel, resident college student and now begrudgingly a protagonist, gets heroism forced on them by the hand of fate. Stuck a world based on another's trauma, their real mission becomes clear: they've gotta get out of here.
This is a metafiction story; both about a non-existent creepypasta ROM hack, the changing tides of Deltarune's fate, and an author getting caught up in it.
Perhaps it means something. Perhaps it doesn't. But it exists, and that's what matters.

Summary
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. The human that fell after them, Clover, would learn some of what they had done and the effects that followed.
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
Snowdin, a place usually synonymous with joyous family outings and quality time, became the stage for a cruel twist of fate for young Kanako. She and her family, the Ketsukane, had ventured there for a day of simple pleasures, unaware of the darkness that had recently descended upon the snowy landscape. A human, clad in a dusty tutu, had arrived—not misunderstood or scared, but driven by a chilling love for the game, a thrill for chaos. In this alternate universe, their attacks were not born of fear, but of a cold, calculated desire to kill.
This human stumbled upon the Ketsukane family and, without hesitation, caught Chujin and Ceroba off guard, slaying them where they stood. All Kanako could do was watch in terror as her parents fell, their forms dissolving into dust. The memory, a searing brand, haunts her to this day.
Now many years into the future, she has grown and changed.

This will include stats, HP, LV, EXP, as well as physical descriptions and small summaries about each character. These descriptions will change as the story progresses, growing as the characters do. Stats are base stats with the stats in parenthesis being their current stats with whatever they have equipped. Finally, I want to make it clear that these are headcannons of the characters, so without further ado, I give you our heroes!

Does anyone want to tell them what kind of sin they committed? After waking up each time, in different timelines, some of which they even know they generated, and others that they themselves didn't commit? Yeah, this isn't going to happen (it happens anyway).
