Nightmare's an asshole, so I force character development on him.or; Dreamtale canon is written via a children's storybook, isn't that interesting?

Summary
Slowly, as if afraid to scare you, the skeleton extended its hand towards you. Most likely, it had no skin. Perhaps it had phalanges and bones. You doubted that a skeleton could have visible muscles. You wanted to check, casting a fleeting glance at the monster's hand.
Suddenly, you felt the pressure of something slightly sharp but strangely smooth on your cheek.
Oh.
The skeleton just poked you.OR
You jumped down, expecting to never open your eyes again. But you did, and then you found a skeleton to be stuck with for the rest of your days. Just the two of you.

Summary
This fic is more of a what if situation. What if instead of Nightmare taking Cross in, Error ended up doing that? How different would things be?
----
Error watches, unflinching, as the skeleton's giant knife materializes, slicing through the stillness of the void. The vibrant glitches around his fingers pulsate more vividly in response, mirroring the tension. Despite the display of power, Error’s demeanor remains composed, almost amused by the dramatic reaction.
"You can call me Error. As for how I arrived here," he gestures loosely around them with a hand threaded with glitches, "I travel where the code calls, where anomalies beckon. Where the multiverse needs cleaned of anything that could harm it, and this place," he pauses, glancing around the stark whiteness, much like his own home, "Screamed for attention."
His gaze settles back on Cross, the colorful chaos of his form stark against the void. "You, however, are an interesting anomaly. Fighting so fiercely, clinging to existence in a world that has seemingly been erased." Error hummed, eyes still searching.

Summary
You are on death's bed, there is no denying it at this point. Your good friend listened to you rave about an upcoming otome game you have been desperate to play since you've heard of it's creation. Only to sadden when your prognosis would keep you from seeing it in your lifetime. Well this good friend manages to get you a copy. So who would have thought that when you eventually passed on, you'd wake up as a healthy you? With goat ears, nubby horns, and a cute fluffy tail? Also a barrage of skeletons waiting on you hand and foot, calling you their queen... After playing many routes, there is one thing you are sure of... To make sure Black doesn't kill you like he does in the game... yet you don't seem to understand the stark contrast of yourself vs the queen as the skeletons do... and if you aren't careful? Black and the others will fall head over heels for you.
