Death Note x reader (guys x reader)

At last

Light's p.o.v.

I was surrounded by darkness. It was to dark to see anything but myself. I was about to say something when--

"Alright, Yagami, I'm done writing your lines of dialog or your thoughts or whatever. I brought you to my world for one reason, and that was not to hear you ramble on about what you're seeing or feeling. It was to tell you to stop trying to kill Mello, Near, and L. I know you don't want to, but you don't really have a choice in the matter. I have already decided you will not kill any of them."

"What are you talking about?! Who are you?!"

"Tsk, tsk. You're very inconsiderate Light. I am someone you have met many times before, countless times even, yet you all refuse to except that I exist. I mean, even the readers don't know who I am. Well, one of them does. Two, if I count myself. But, while I would absolutely love to continue talking to you, I must address the readers now. They are more important now. This is their story after all."

"Wait, what did you-"

"QUIET. Ugh, alright, Reader. Do you know who I am? The last person you would expect, unless You are Gisselle. In which case, don't spoil anything for our other lovely readers~! They need to find out for themselves. Anyway, readers. Look forward to more appearances of me."

"Oh, before I force Yagami to leave, I'll give you a RIDDLE to figure out who I am."

"If I am always watching, yet am never seen. If I am always talking, but never heard. If I am writing something, something that you think you need. What ever could I be? And I usurer you, you know a lot about me~."

"Wait! How did you decide that I am not allowed to kill L, or Near, or Mello!"

"...Sorry, Yagami-San, but I cannot tell you. The readers will have to figure it out. Now, bye bye. There are plenty of things I Have to do to prepare my pocket dimension for. Ciel, Cipher, come. We have much to prepare. Audios, Yagami-San~."

I saw three figures appear before I was dragged back to reality. One, was a glowing gold color and appeared to be in the shape of a triangle. This one appeared to only have a single eye, a top hat, and a strange cane. The second, was a boy, about thirteen, with blue-grey hair and an eye patch over his right eye. He two wore a sort of top hat, and also a cloak of some sort. Lastly, there was...a girl. I had no Idea what she looked like, because she was walking away from where I was. I could see nothing of her except her brown hair that was trailing behind her. If I didn't know better, I would assume that she was the one who was talking to me.

"Heh, Kid you know what they say about assuming things, right?" The triangle asked me, as I was enveloped by darkness once again.

"It makes an Ass out of u and me." The girl said with a chuckle. 

"Time to leave, Yagami."
