    Summary

    Either you're dreaming, hallucinating, or dead because you don't know how else to explain your current predicament. Seriously, how else do you explain suddenly appearing in an unfamiliar (not to mention absolutely filthy ) basement full of more tech bits than a computer repair shop?

    Oh, and also the skeleton. You know, the one from that one game? The one that got into Smash but only kind of? But maybe you should rephrase that to skeletons because it looks like the many iterations of him and his brother are here, too.

    Summary

    Once long ago, humans and monsters lived alongside one another. During this time it was an age of unparalleled magic and strength in the two sides.

    However, the great war happened, and with the absence of monsters mages slowly died out. After all, humans are not inherently magical. With no more magic to keep the blood lines going, magic is all but a fantasy in the humans of today. That is, until an eccentric billionaire decides the mages need a come back.
    Looks like you and a few others are just the right subjects to get the ball rolling.

     Oh right! There is some swearing in here.

    *WARNING* Some people are very sensitive to kidnapping/abduction themes. While I assure you, I probably won't go too dark, it is a bit... muddy in here. Tread lightly.

    Summary

    You went to the bookstore one day to buy some manga.

    You got a whole lot more than you bargained for.

    You end up somehow saving the Royal Scientist's life, and her fiancée can't thank you enough for it.

    So that's how you find yourself surrounded by people who love you for who you are and don't want you to change.

    But what's up with these strange dreams you're having? And, why does a certain punny skeleton get so spooked at the number 17? And...who is that tall skeleton with cracks in his face that you keep seeing in your dreams? Did the ambassador of monsters just join your swim team? Can this summary get more cliché?

    Summary

    Your name is unimportant. Your job is nonexistent, really. And your (ex)roommate just kicked you out in the middle of a surprisingly cold November night. But whatever. You don't care. You'll be fine.

    Keep telling yourself that as you freeze to death, idiot.

    But you'll be fine, for one reason! Two, actually. Two people - monsters really - who just so happen to have the same names as some fonts you know of? You stay with them instead, just to get back on your feet, and a single question rises to your mind.

    What the hell is keeping you here?
