Summary
They say life is full of surprises, but [Name] never expected to end up in an entirely different universe, one filled with monsters, souls, and magic. But this isn’t some happy fairytale; it’s reality. And reality bites.
Adapting to this strange new universe feels impossible, especially when the skeletal monsters causing you trouble also happen to be your roommates. And 'passive-aggressive' doesn’t even begin to cover it. Still, no matter how lost or out of place you feel, you refuse to let go of hope.
After all, if life can surprise you once... who’s to say it won’t surprise you again?

Summary
Long ago on the surface as the light of the sun gave protection. Humans and monsters live in peace and humility side by side, as days pass and the small village starts to advance. A sickness struck, humans baffled by this as they struggled to find a reason why as the ill became fatalities. The odd part as none of the monsters became sick, anger on one side bled into the other when an irredeemable action was made and war started. irreversible damage on both sides as it escalated. The Queen of Monsters as a last resort tried to plead mercy with humans of the village. After the case was solved, they agreed with the monsters being sealed down.
Tragedy struck monsterkind, the King of Monster declared war on humankind with the goal of getting 7 human souls. With the disappearances, humans fought back and with the amount of lives lost, the ones with the strongest [DETERMINATION] able to be contained.
Years later the war was forgotten as civilization advanced. The missing cases caused in MT. Ebott made them put up warning signs warning anyone from venturing into it as a way of preventing.- Language:

Summary
After years of confinement, monsters have finally escaped Mt. Ebbot. Initially, the world struggled to accept their presence, but over time, humans and monsters forged a fragile peace. Yet, beneath the surface, something remains amiss.
You carry the weight of a fractured soul, scarred by past traumas. In a world that seems to have moved on, you're left to navigate the shadows of your own pain. But you're not alone. In the depths of this new reality, you cross paths with another broken soul—Sans.
Once a figure of terror, now a shadow of his former self, Sans understands the darkness that clings to you. Together, you embark on a journey of healing, trust, and the possibility of redemption. But as your bond deepens, so does the question: can two shattered souls truly mend each other, or will the weight of their pasts pull them further into the abyss?

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.
