(Y/N) stood on sidewalk as she watched a baseball game near by. The emotions the baseball players had on their faces made her smile. The players did whatever they could for their teams. She envied them deeply. (Y/N) bet her bottom dollar that they were all friends and were having fun.

Fun she couldn't even have.

Her smile was still planted on her lips as she looks away. Not noticing one of the players yell at her to move. The baseball was knocked out of the lot and was heading straight towards her!

"*Bonk!*"

"Ow-! Damn that fucking hurt." (Y/N) whimpers in pain, scratching the back of her head. Looking down she sees the baseball that hit her.

Her mouth turned into a huge grin.

Picking up the baseball, she rushed over to the field. "Hey! You guys lost your ball! Do you need another player?!" (Y/N) exclaimed with excitement.

Hoping she could join in on the fun. One of the players noticed her figure and told the others to stop playing since someone was coming on the field. (Y/N) walked over to one of the pichters. Her tall height and slow steps made the little boy shiver in fear. "Hey, your ball went out of bounds, you guys need someone else to help out?"

(Y/N) replies calmly with a toothy smile at the end. The boy gets out of his fearful daze and yells at her.

"No! We don't need players!!"

(Y/N)'s happy grin turned slowly into a frown. She wasn't even surprised by the kids remark. "S-sorry.. I'll leave this here." The young high school student drops the ball on the floor and left the field.

Going back on the sidewalk, she watches the game resume like nothing happened.

(Y/N) then heard footsteps coming close to her. Looking over her shoulder, she sees a small man with a hat next to her. The little man looks up to meet (Y/N)'s. He then screams in fear. "Y.. Y-your hight, my friend.. It's abnormal!" The little man points out, making the female drop to the floor in sorrow. The little man realized his mistake and tries to actually say what he meant.

"What I meant to say is that... You have tremendously unlucky fate because of your hight."

(Y/N) nods, agreeing with the stranger. "Yeah, I already know sir. Thanks for pointing that out..." (H/C)-nette replies sadly, her mood dropping more and more. "I can't do anything about it sir, please excuse me." (Y/N) says with very little politeness, getting up and starting to walk home.

"Wait! You must not go in that direction!"

(Y/N) waves the guy off, "bye sir!" She calls back, starting to run home before the sun sets. The little man looks at retreating figure. "That poor girl, I hope nothing happens to her. But I'll say her last rites anyway," the little man prayed.

On her way home, a car stops in front of her. (Y/N) felt fear enter her body but she couldn't run away. She was stuck in place, not even reacting when a buff man steps out the car. He wore a black suit, black sunglass and a black fedora. With a huge frown on his face.

He grabs (Y/N) and throws her into the car. The female screams in fear as she tries to struggle out the guys grip. "Let me go! Please! Who even are you guys?!"

(Y/N) cries out as she kept struggling.

The car drove fast making her attempt to escape slim. Hat man kept his hold on her as she kept trying get out of his grip. Not realizing that there was another person in the car. The car then stops abruptly out of nowhere and the poor girl falls out the car once one of the doors open.

"We arrived at your house, miss." A guy in the car she didn't notice before tells her. (Y/N) pulls herself off the floor as she looks at her surroundings. Army men stood outside her apartment. Holding guns and were placed in tanks as well.

(Y/N) knew something wasn't right.

The man that go out the car with was a old man that wore the same clothing as the other guy. "Do.. Do you want to come inside?" (Y/N) blurted out stupidly, mentally punching herself in the face. Mr. Old guy nods as the two head up to her apartment.

When she walks by her neighbors doors, they all had army men posted outside their door. Once the two reach her door, two army men equipped with guns allow them in.

(Y/N) takes off her shoes at the door and was about to head into the living room. But a young male around (Y/N)'s age jumps in front of her. "(Y/N)!" The teen yells fearfully, taking her into a hug.

"Shinobu?! What on earth are you doing here?!"

Shinobu is a bit short and skinny for a boy. Yet he was down right cute in a way. He had short straight brown hair and black eyes. Wearing a simple hot pink t-shirt and jean shorts and a pair of black flats. "I saw the news and I was so worried.." He mumbles into (Y/N)'s stomach.

"Shinobu.." (Y/N) looks down at her with soft eyes. He was one of the only few friends she had. Shinobu stuck with her through thick and thin. He and a few others were the only people besides her parents that would not look at her like some type of giraffe. Breathing in and out, (Y/N) relaxed her nerves. Shinobu was what mattered right now, not her.

"Shin.. It's okay, whatever's going on I'll try to fix it. I promise, p-please don't be upset 'c-cause of me. Then I'll start crying and it would like I have two waterfalls coming out of my eyes. Hehe.." (Y/N) jokes, trying to calm Shinobu down. The teen laughs lightly as he let's go of his friend. (Y/N) smiles as Shinobu musters up a grin. "Idiot.." He chuckles out.

Mr. Old guy ruins the moment by taking (Y/N)'s arm and starts dragging her into the living room. He then throws her onto the floor. (Y/N) gets up and was about to cuss out the old guy, but then sees a gaint horrifying man sitting right in front of her and her coffee table.

Instead of feeling fear, she gave him a small strained smile. (Y/N) knew she was tall. But this stranger was much bigger than her, she could respect that. "Ms. (Y/N), our guest here is Mr. Invader who has come from beyond the galaxy... To take over the earth."

"Oh, really..?"

"That's right, my dear girl. I'm Invader. Nice to meet ya!" Mr. Invader said with a kind smile. (Y/N) copied his smile. "It's very nice to meet you Mr. Invader. Would you like some tea, or can I offer you a snack?" (Y/N) asks, wanting to be a polite hostess even durring this odd situation.

Mr. Invader shakes his head, but thanks her for the offer as he pulls out a piece of paper and hands it to her. "Oh, thank you sir." (Y/N) takes the paper and reads it. It even had a small chibi picture of him on it...

"So, you want me to have a duel with Mr. Invader?!" (Y/N) yells out in fear with wide eyes. "Yes. His people have given us a condition regarding their invasion of Earth. Their computer chooses a inhabitant of Earth to fight for our planet."

"And has randomly chosen... You. Ms. (L/N), you get to have a duel with him, and if he loses.." Old guy let's Mr. Invader continue.

"We'll go back home in peace."

"Please dedicate your young life in saving our planet."  Mr. Old guy bows his head. "Um... I don't know..." (Y/N) responds with anxiety dripping from her tone.

"Please, I beg you." Old guy said with more emotion. "I..I...I-" Before she could give her answer, the ground started to shake rapidly. (Y/N) holds Shinobu in fear. "Is this an earthquake!?"

"Right on time. Your opponent has arrived." Mr. Invader said, looking up at the ceiling. While (Y/N) and Shinobu sat in place, unaware of the giant spaceship covering the entire city. Suddenly a bright light came crashing through the room. Making everyone fall back and thrown off to the side.

The light soon stops, but in it's place was a boy. "Sorry to keep you waiting! I'm your opponent, Lum!" The young male Oni said with a smile. His tiny white fangs slightly peeking out of his mouth.

(Y/N) inspects the new person, or "Lum". Lum had average height of a teenage human and wore a yellow tiger print clothes that covered bits of his body. He had somewhat short, soft looking green hair. As well as having two tiny horns on his temples.

(Y/N) was no longer taking in the boys features. But instead looked at Mr. Invader, Lum looks a bit like him! "Excuse me, Mr. Invader?" "Yes, Ms. (L/N), what is it?" The (h/c)-nette stares a bit more at Lum before looking at Mr. Invader.

"Is Lum your son? He looks almost like you." (Y/N) points out with a thoughtful tone.

"Yes ma'am, this is my son Lum." Mr. Invader says pridefully. Gesturing to his son that stood beside him. "If you can grab his horns in a game of tag within ten days.. We will not concur your planet."

Once that was said the air grows tense and everyone went silent.

(Y/N) gets up and takes a few steps towards Lum. Her face facing down at her feet with unreadable look on her face. Walking slowly until she was standing in front of the teen Oni. Lum could feel a bit of sweat on his brow as he watched the female human stalk closer to him. (Y/N) stopped in front of Lum.

Not uttering a single word. Just standing there... 

Compared to Lum, she was much taller than him so he had to look up at his opponent. Though once he did, Lum saw a bright polite smile. Holding out her hand, the female human said. "Hello, Lum. I'm (L/N) (Y/N), welcome to earth!"

"....."

"......"

"Thank you..?" The teenage Oni blinks, greatly confused before taking the humans hand. (Y/N) smiles, giving his hand a firm shake. She then let's go and goes back to her seat next to Shinobu. Said male was glaring daggers at Lum.

"Well I guess that settles it." Mr. Invader announced, not caring about how (Y/N) didn't give her answer. "Thank you Ms. (L/N) for fighting for earth," Old guy said. (Y/N) pales, "h-hold on a second! I didn't agree, all I did was shake Lum's hand in greeting-!" (Y/N) tries to reason, but was soon cut off by hundreds of reports filling into the room.

Forcing Lum and Shinobu to stand right squished between her. Reporters asked questions left and right. Flashes of the camera was all could she see. Making her a bit dizzy. A reporter called out: "Ms. (L/N), the responsibility you bare is grave! Your thoughts on it?"

"No comment..."

✨💫✨

It was now finally the time to start the race. The clock that signals the end was ticking as (Y/N) tied her sneakers laces. Doing a small stretch, the female looks over her shoulder. Seeing her opponent jumping up and down for a warm up.

"Get ready!!" The announcer calls, making the two players get in their positions. "Start!!"

(Y/N) runs over to Lum with a war cry! She jumps at him in hopes of catching him. But instead of his body underneath hers, he was floating above her. Getting up from the ground, (Y/N) looks up at Lum. "You could fly!?"

"Why didn't you say anything! No one said that you can fly?!" Lum chuckles at her, "you just didn't do your research!" He winks afterwards, running away from the pissed female.

After many attempts of catching the male Oni. They all resulted in failure.

Now it was finally the ninth day, another attempt at catching Lum ruined. (Y/N) gazes at the night sky she used to love. One of the things that brought her comfort before all this battle of cat and mouse between Oni and human. The T.V in the other room blared static instead of anything else. She really needed to get that fixed...

Sighing, (Y/N) lowers her head in shame. Shinobu, who came into the room earlier, gave her a pitied look. "I should of asked if Lum could fly! No. I should of rejected the idea of battling against him!" (Y/N) yells, punching the wall with little force. Not wanting to destroy her room.

Shinobu speaks up, "(Y/N) if you don't win.. We won't be friends anymore!" (Y/N) looks at Shinobu with horror. "Y-you can't be serious... Right?!"

The female stutters out as she grips her arms. "I am! I won't be able to be friends with you if you die!!" (Y/N) went silent from Shinobu's words. "But if you win..."

"We will stay friends and I'll take you out on a lunch date." Shinobu states, while (Y/N)'s eyes widen at her proposal. "Lunch... Friends again..Date..."

She mutters out with dazed face. (Y/N) shakes her head. "Okay!" The T.V that was once staticy played a commercial, which gave her a idea.

It was now the next day. The two teens stood on the road facing one another. Readying for the last battle deciding earth fate. "Listen to this crowd cheering!" The announcer spoke.

"This is the Final Day, at last. But, look at (L/N)! She shows no willingness to move at all!"

'For friendship, I'm doing this to save the only people that care for me! No matter how dirty, I'll save earth! God, that sounds just like those superhero in manga say. Ugh, whatever! I'm not gonna lose!'

"FOR A LUNCH DATE!!!"

Pulling out a grappling hook, it manages to wrap around Lum's waist and pulls him towards her. Running at full speed, the two body's clash and fall to the ground. Lum goes head first into her breasts. 

The Oni blushes at the contact of skin. His milky skin becoming red as he tries to push her away. Ingnoring the soft flesh as the two restle on the ground as Lum manged to push her onto the floor. His arms caging around her, keeping the two in place. The young Oni pants tiredly, his warm breath brushing against the humans neck while his green locks are matted against his forehead.

(Y/N) shifts a bit underneath him, but stops when Lum growls angrily at her. 

Slowly raising his body, the alien was about to fly away. But before he could, (Y/N) raised her arms quickly and pulled him down so he would remain on top of her. Finally grasping his yellow horns, accidently pushing him into her chest area again.

"SHE'S DONE IT! OUR GREAT SAVIOR, (Y/N) (L/N), SAVED EARTH ON IT'S FINAL DAY!" 

(Y/N) smiles happily, hugging Lum tightly. Not caring if he was still connected to her body. "Yes! Now I can still have my best friend and go on a ramen date! Maybe I'll find someone at the restaurant and we'll hit off and get married!" (Y/N) rambled, to excited to think about what she was saying.

The male alien's eyes become hazy as he inhales the scent of her skin to himself.

"Oh, I get it. Okay, if you insist, I'll marry you!" Lum said, wholeheartedly returning the girls embrace, snuggling into her breasts. The female froze at what she heard come out from Lum's mouth.

"Huh?"

In at least a second, reporters stand around her. Asking her questions about her "marriage" and "fiance". (Y/N) could feel her face drain of colors as she tries to clear up the misunderstanding. What made it even worse was that Shinobu walked over to her and Lum.

Enraged.

"You can forget about that lunch date. (Y/N)." The short haired teen seethed. The tall female felt herself grow faint from everything happening so fast. Lum's hands never leave her waist as he stared at (Y/N) lovingly. "Darling~", ""Darling"!?"

"On my planet, marriage proposals are sacred. I'll dedicate my life to loving you forever. And if you cheat on me..." A sharp scream erupted from her lips as a huge force of electricity shocked her body.

The tiny man from before stood in the crowd. "This is fate." He prayed.

(Y/N) felt her body becoming slack as she slowly loses consciousness in Lum's arms. Her (e/c) eyes fluttering shut as her head leans against the Oni's chest. "Darling!" The alien purred sweetly, nuzzling into her (s/c) neck.

(Tell me what you think! This is my first time writing for this anime and show. Also, originally, I wanted to call this story Mr. Alien and Miss Earthling! And Ataru is gonna show up in the next chap?)
