I...may have created my own game... so it's pretty simple and stupid-
I am trying again for the non binary people.
You're the sister/sibling of Chishiya

Usagi and Arisu... the obvious match.

No one would ever think of Arisu and Y/n, the friend of Arisu and it made Y/n tear up.

They met Arisu in the second game, and while Chishiya was just...hiding away from the bullets, Y/n did the dumb idea and jumped infront to knock the gun away, although while doing so, they got slashed by a knife on their leg. And that gave enough time for Usagi and Arisu to press the buttons. Chishiya silently smirked to himself. He knew his sibling (or sister, I am trying to learn how to write a non binary reader, so I'm sorry if it's incorrect) wouldn't risk something like that for someone new, so this 'Arisu' person must've done something for her.

Now, people were paired up in teams of two, and Arisu was with Usagi, while Y/n was with their brother, Chishiya. Y/n slightly glared at Usagi, but they knew nothing good would happen if they only had hate. This just pissed them off even more. They wanted to hang out with Arisu, but alas, nothing could happen. The teams were already made.

The teams went to separate games, Y/n and Chishiya with their own brought weapons to the game. While Chishiya had his taser, Y/n kept small throw knives in their jacket and boots.

As they arrived at the game, it turned out Usagi and Arisu had the same game with Chishiya and Y/n. This pissed Y/n off. They just stomped off as they saw Usagi hug Arisu and kiss him on the cheek, making Arisu look at her with a red face.

"A little bit more red and it would make you seem like a rose. What's up, Y/n/n?" Chishiya asked/teased. "Nothing." Y/n growled out, looking at Usagi and Arisu. Chishiya followed their gaze. "Ahhhh! I see it now, sis. You're jealous. Hmm...jealousy isn't your colour." Chishiya teased.

"Oh fuck off, you bitch." Y/n joked, shoving off a laughing Chishiya away. Y/n smiles before looking back at Arisu, then they follow their brother.

Chishiya and Y/n made their way to the entrance of the game, where they were met with Usagi and Arisu. Ugh, those two again.
They made their way to a "mountain"

"Hey Chishiya-san!" Arisu said shyly as he saw Y/n.

"Registration has closed.
There are 16 participants
Game Name: Climb
Game difficulty: 5 of Spades.
Game Rule: First to the top and reaches the goal, wins.
Time limit: 120 minutes"

The female voice said.

Oh, this was gonna be good. A game of spades, and Y/n was really good with spades. And climbing? They smirked to themself. Everyone prepared themselves with the climbing gear. Arisu, Y/n, Chishiya and Usagi all stood together. "Good luck, guys." Y/n said.

"Game start."

Y/n ran forward, the other 15 players after them, Usagi with them in the lead. Then, the climbing began.

It was quite easy at first. Chishiya slightly struggled, but he was able to climb up easily with his sibling's help. They began climbing, but the higher they climbed, the more they found themselves surrounded by fog. At some point, Y/n heard screams. They looked up and a body fell on them, causing them to swing to the side to not fall down. They swing aside and heard machine guns. Y/n screamed for a second before they swung into someone, and they both swung into a cave.

Y/n felt a large weight on top of them. They looked up and saw Arisu. "Arisu...can you get off of me?!" They snapped, startling him. And it took Arisu a second to figure out why. He was basically on top of them, and their lips were close to his.

Meanwhile

Chishiya continued climbing. "Y/n!? Where are you?!" He yelled worriedly. "Arisu!" He heard a female say from the distance. "Chishiya?" The same voice said as he turned to see Usagi. Usagi and Chishiya decided to team up and stay together (kinda against Chishiya's Will) They both looked around and saw a cave. Maybe they could rest there. Chishiya was getting tired. "Usagi! I need a small break."

They then stopped and entered the small cave.

Arisu was about to walk out of the cave and before he did, Y/n ran forward and pulled him back. "NO DON'T!" And just as they pulled him back, a gun shot was heard.
"What the-"
Y/n slapped a hand over his mouth. "Arisu, they are targeting the climbers. Stay here, I'll be back."

And Y/n peeked around the corner. And just before anything happened, as Y/n pulled out a throw knife, both of them heard a sound. "Stay behind me." Y/n whispered. They all hid behind a rock, jumping at each other.
It was Chishiya and Usagi! Chishiya had his taser out while Y/n had a knife to his neck. "Y/n?" Chishiya hugged his sibling/sister and they smiled.

Y/n explained the situation of what happened and they decided to continue into the cave. Everyone stayed together until when they reached a bigger opening. Gunshots were heard and it made Y/n panic. They looked to their side to see Arisu.

It's now or never. She thought to herself. "Arisu. Judging by the guns, I don't know what will happen. So I just wanted to say this: I like you. I have noticed that when we met for the first time in the Tag game. I regret not telling you earlier, but here's the truth. I love you." They said, loud enough for him to hear over the gunshots. He couldn't react. All he did was jump forward and kiss them. They kissed him back. Then they pulled away and pulled out one of their many throw knives. Chishiya once gave them advice on to use the reflection of the knife to see behind them, so they did just that. "Three shooters." Y/n muttered. They turned to face Arisu again.

"When I say run, you RUN, is that understood?" Arisu's eyes widened. "No! You have to come with me! Please!"

They smirked. "If you're scared they're gonna kill me, don't be. Trust me, Arisu."

Arisu looked at them hesitantly. "Alright. But come back alive, please!" He begged. Y/n nodded. "Of course."

They counted to 3 and then they threw two knives, successfully hitting one of them. "RUN!" They yelled at Arisu. Arisu ran fast and deeper into the cave.

Arisu found Usagi and they teamed up. They found a specific powerhouse to everything.

"10 seconds remaining." the AI voice said, startling Arisu and Usagi. They found the switches and pulled them. A huge wall then went down and revealed a button.

"Now this is getting complicated." Usagi muttered to herself. A soldier came up and tried to fight them, but it was quickly stunned. They turned around.

"PRESS THE BUTTON!"

"3. 2."

Arisu pressed the button just as the AI said one. Chishiya ran back to see the guards heads explode, like in Tag. He and Arisu saw Y/n on the ground, holding their arm. It shot their right arm, which was luckily their non-dominant hand.

Chishiya hugged them and frowned. "We have to fix that." He said. Y/n nodded and turned to Arisu. "Told you I'd live." They smirked and pulled Arisu by the shirt and kissed him. He was frozen in shock, but then he kissed them back, cupping their cheek. Y/n licked his bottom lip, which caused a quiet moan to come from him. When they pulled away, Arisu looked at her, as if he was curious to why they stopped the kiss. Y/n rolled their eyes to Chishiya and then smiled. Arisu blushed and looked away, putting on his hood. "You're cute when you blush, Arisu." Y/n whispered in his ear with a smirk on their face, walking away to Chishiya.

"Come on, Arisu. Let's go." Usagi smiled at her friend's dazed expression. "Ok." Arisu replied dreamily, his eyes following Y/n.
