If you don't know who he is or how he looks like he is basically a demon. Also you are about to turn 10.

(Y/N)'s POV
"You mean we finally can have a break?!" I asked my dad with shock and joy. My whole family are born with amazing voices so we always perform at parties, entertain a town, and even star in musicals. Though singing all the time is exhausting. I live with my dad, older brother and sister, my aunt, uncle, and my six cousins which who are all older than me. Since we have the greatest voices in my town we earn a lot of money but I want to rest. "Yup for a few weeks." My dad informs me. I smile and cheer as he chuckles at me. For the first time in years we get to have a break. Greatest week ever. I walk outside feeling the wind touch my skin and the sun glow on my skin. I run to my favorite spot in my whole town which is the cliff. Unlike most nine year olds I know when I'm getting too close to the edge.

I sit down near the edge but not to close as I gaze at the forest in front of it as well as the horizon. It really is a pretty sight which I'm glad to see again.

THUD

My body flew up and fell back on the ground of the cliff. That is not normal. I get up and look around to see no one or anything that could cause me to fly me in the air. While gazing around I see a tail of some sort slither in huge cave. Forgot that was there. I walk towards the right side away from the edge of the cliff to the forest. Though the cave isn't that deep in it. I make my way into the cave only to met with stinky breath. "Who goes there?" He has a very low voice and it sounded mad. "Hello I'm (Y/N)! I think it's better out there than in here." I suggest. In here it is dark and spooky not a very good place to be in. Chuckling could be heard in the darkness of the cave echoing every slight sound that happens in here. "Foolish mortal you wouldn't want to see a terrifying monster now would you?" He questions with what sounds like happiness and curiosity. Happiness isn't the word more like sinister. I raise a brow. He probably doesn't live where I live since there are monsters there too. "I've seen many and they are all nice and you might be too." A few seconds later loud thuds can be heard. It echoes throughout the cave. It gets closer to me as the sound increases. After a few moments it stops. A dark silhouette is in front of me, crouching so he doesn't hit the top of the cave. It looks to have horns and wings. Orange dots glow in the dark as not much can be shown.

I back up to the entrance in case he was trying to leave. "Aren't you going to come out? It is a beautiful day." I smile at him. Deep breathing is all I heard as well as the wind hitting the trees as the leave rustle against each other. I wait until thuds could be heard, the cave falling apart as he rises up to the sky to show himself. My eyes widen as I back away a bit. A skeleton with a black shirt or something that doesn't cover his rib cage, black collar with a blue chain attached to it, black shorts, black sandals, a ling tail that is just bone, large demon like wings, and horns. (I know he really doesn't have a tail or wings but screw that!) "Oh.....my............gosh......you're a...a.....giant!" I yell with excitement. He makes a confused face as he sits down on the ground. My eyes turn into stars at the sight. We learned about this at school and if you find one good things come to you!

I run to his hand and compare it to my teeny tiny hand. "You look so cool Mr. Giant!" I smile while jumping up and down. He rolls his 'eyes' at me and looks away. He is a bit rude but he can change everyone can....at least I think they do. The wind lifts up his shirt or sweater a bit from the wind as it does to my clothes and hair. "What's your name?!" I yell. Since he is tall he might not hear me. He continues to look at the view in front of us. I sigh and sit near the edge looking at the horizon. Might as well enjoy my break. "Sans." He states. My eyes widen a bit as I look up at him. His iris' look down at me and then back at the horizon. I smile and look back at the horizon. "That's a cool name, Sans." He makes the 'tch' sound at me. I ignore it since that is what I always do. Then it occurred to me. I jump up and look at Sans. "I have to go home! Hope to see you soon." He doesn't look at me. "I hope that doesn't happen. You are very obnoxious and a bothersome. The last thing I want is to see a another mortal like you." He looks down at me. A laugh escapes me. "You're funny. You should know though if I'm like that or anyone else they are the happiest person in the world....to me anyways. Bye!" I run home.
