Summary
Alternative Title: I Found Myself In An Isekai Styled Game Of A Game I Barely Know
How’d I get so lost that I found myself in a different dimensional plane?
—
“why is it… every time i see you, your flavor text is always written as ‘confused’.”
“… It’s my default….”
“i find it funny how you sound both confident and confused with just that.”
—
Basically you fell in the middle of the Underground and you just remembered this is a game you played once and never thought about it again. No amount of isekai mangas, reincarnation manhwas, and magical manhuas could ever prepare you for what you should do in situations like these. Because honestly, the fact that you know absolutely nothing outside of playing the neutral route was already a disadvantage.
However, you can’t remember if there was an element to the game that included the enslavement of the whole monster race after they got out of the Underground.
Nor can you remember that there was any sort of color to the status windows that keep randomly popping up out of nowhere. Not that you were complaining since these status windows are what keep you alive from this… chaos…

Summary
You're an office worker living in Ebott, one of few humans who had decided to stay after the monsters emerged a year prior. When asked why on earth you didn't hightail it out of there, you'd say that you, for one, welcomed our new monster overlords.
But despite the jokes, deep down you were excited at the prospects of an entirely new and fantastical species, plain and simple.

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.

Summary
“What is it you desire most?” the shadow called.
“To sleep.” you answered.
With a tilted chin, the embodiment of darkness echoed the statement inquisitively, “That is a rather mundane request,”
