Kayobi's Days Off

My name is Kayobi Taida...at least while I am on Earth.  And I'll make this simple, I'm what they call a 'Swapper'.  A shape shifter, as you humans refer to it.  More than that, I'm also what we call 'painters'.  In your terms, that would be an 'assassin', far too crude a word for a profession as artistic as my own.  I travel around the galaxy, painting the walls of the halls of power with the bloody innards of various dictators who aspire to conquer worlds...and I'm very good at my job.  I daresay I'm even the very best at it.  Between magic and shape shifting, there's not many people I couldn't get to... but this story, is not that one. I work hard, you know, so I deserve some time off, damnit!  I'm well paid and well compensated for my work, so it would be a damn shame not to take every vacation I'm given.  So where do you think I spend my free time? I go to Earth, to a little place called Shinjai, where I live as a NEET in disguise as a pretty young human.  All I really wanted to do was two fold...avoid doing any chores whatsoever at any cost... and watch my favorite Earth anime...and eat snacks... lots and lots of snacks.  Oh and sleep in...  a lot.  Fine, that was more than two things, but damnit it's my vacation and I'm allowed to be sloppy! Anyhow, this is the story of my days off, with all its happiness, sadness, and...various shenanigans.
