Before I start, I wanna say that I don't really know much about Clio so I'm just going to try my best. He's not a very well-developed character I don't think. But here goes. 

Requested by: Pokemon_Fangirl23  I hope that you like it and I'm really sorry about how long it's taken me to write this one.

Your POV

You're dating a vampire. Well, not really, but your friends Valt, Honcho, and Cuza think so. You're a member of BC Sol alongside them and you see Clio every weekend. This weekend is no different.

"Where are you off to?" Honcho asks you. 

"Off to see Clio," you tell him excitedly. 

"Eek! I hope that you're okay. Don't let him suck your blood!" Valt warns you. You giggle and reply,

"He's not a real vampire, Valt." You run off and Valt looks worried for you.

-Time Skip (the next day)- 

"Y/n!" Clio yells, running over to you and kissing you on the lips. 

"Ow! Clio, watch your teeth. They're sharp," you say after one of his "fangs" hurts your lip. 

"Sorry, love," Clio replies, letting go of you and taking a sip of his tomato juice.

"It's alright," you giggle. Clio dramatically fluffs his cape and then asks you,

"What do you want to do today?" You smirk and reply,

"I have an idea, actually. How would you feel about playing a prank on Valt, Honcho, and Cuza?" Clio smirks evilly and tells you,

"That sounds perfect. What do you have in mind?" You tell Clio all about your plan and he nods his head afterward, smiling. "Let's do it," Clio says, his mind set. You smirk and grab Clio's hand, pulling him along behind you to your destination. 

-Time Skip- 

"Alright, done. Now, time to go and see the others, Y/n," Clio says to you. You smirk, touching your neck where the two bite marks that you painted on are at. 

"This is gonna be great," you say to him. He nods and pushes you towards the door. You walk out of the door, heading for BC Sol. 

You find Valt, Cuza, and Honcho in the gym, battling with their beys. Taking a deep breath, you walk through the doors. You walk over to the guys, acting like you're out of energy. The guys see you walking weirdly and Cuza asks you,

"Y/n, you feeling alright?" You groan and say,

"I don't know. It's weird, but it's like I have no energy left. And I'm super light-headed." Honcho frowns and questions you,

"When did this start?" You pretend to think.

"Last night. After I got back from hanging out with Clio," you tell him. Valt looks really worried. You scratch at your neck, "And my neck hurts really bad. Right here," you tell them, pointing at the spot where the fake bite marks are at. The three of them gasp. 

"You said this all started after you hung out with Clio?" Valt asks, scared. You nod your head and then pretend to collapse onto the ground. Honcho and Cuza rush over to you and help you up. 

"Let's get you back to your room. I think you should rest," Honcho says to you. You agree, allowing the two of them to walk you to your room. 

After the guys have put you in your bed, they walk out into the hallway and begin to talk. 

"Did you see those bite marks on Y/n's neck?" Cuza asks the others. They both nod. 

"I knew it was only a matter of time before Clio came after Y/n. He is a vampire after all. He probably can't control his cravings for blood," Valt says, terrified. 

"What should we do?" Honcho asks, panicking. Cuza's eyes widen and he replies, 

"I don't know. Do you think... do you think that he could've turned Y/n into a vampire too?" The other two gasp. 

"I didn't even think about that," Valt says, "Let's keep an eye on them just in case." The other two nod as then look at the door to your room and then walk off. On the other side of the door, you smirk, hearing the whole conversation. 'Time for step two' you think to yourself, looking at the cup of tomato juice that Clio had given you.

-Time Skip Again-

The next day, you wipe off the fake bite marks and grab your cup of tomato juice. You pour it into a water bottle that you can't see through to hide the liquid for now. After doing so, you walk out of your room and head to the cafeteria for breakfast. 

You walk up to Valt, Cuza, and Honcho and sit down next to them. You notice them look at your neck and then nervously look among each other. Smirking, you tip your water bottle over and the red liquid seeps out of the cup. You pretend to panic and you pick up the cup immediately. You jump up and grab paper towels to clean up the mess. 

"What is that?" Valt asks you nervously.

"N-Nothing," you stutter, pretending to panic again. Valt's eyes widen and he looks at Cuza, who also looks freaked out. "Let's just eat," you say, changing the subject. The others slowly begin to eat their food, while you just stare at yours. Instead, you just sip out of your water bottle as the others watch you. 

After breakfast, you all head to the gym to train. On the way, you look at a bulletin board that has a list of the bladers who are facing off in your upcoming tournament. Honcho grabs the paper too fast and exclaims,

"Ouch, paper cut!" You smirk at the opportunity, pretending not to notice Honcho's cut. 

"Do you guys smell that? It smells delicious," you say. Then, you look at Honcho's cut and see a small amount of blood. "Oh," you say simply, "Excuse me." You walk off quickly. Valt watches you run off and turns to Honcho,

"Did you see that? They ran away after they saw your blood." Cuza nods, frightened.

"Yeah, and they said it smelled delicious. Creepy," Cuza replies. You smirk from around the corner. The guys shake it off and go around the corner, seeing you there. 

"Weren't you supposed to go out with Clio this afternoon?" Honcho asks you, still rattled from the previous event. 

"Yeah, but we rescheduled for tonight. It's too bright outside. I mean, it's too hot outside," you say quickly. The others all tense up and look at you with wide eyes. You turn around and smirk before asking,

"Now, come on. Are you coming to train or not?" They follow behind you, leaving a safe amount of room in between you and them. 

-Time Skip(last one I promise)-

You run up to Clio, kissing him on the lips quickly. 

"They're totally falling for it," you tell him, smirking, "Now for the grand finale. Come on, I need you for this part." He smirks and follows you to BC Sol. 

You knock on the door to Valt and Honcho's room, knowing that Cuza's in there too for a sleepover. They open the door and see the two of you standing there. Valt gasps and asks,

"Wh-What are you two doing here?" You look at Clio and then say,

"We're hungry. You guys wanna come with us to the cafeteria? It'll probably just be us five. Then we can catch a midnight snack." Cuza replies nervously,

"S-Sorry. We're really t-tired, so we're just gonna stay in tonight." You shrug and turn to Clio, pretending to be disappointed. 

"Alright," you say sadly, "See you guys tomorrow." They close the door and you and Clio laugh quietly. 

"They were so scared," he whispers. You giggle and kiss him on the lips. He kisses back and then you two pull apart. You take his hand in yours and then the two of you walk off.

-Bonus- 

Valt, Honcho, and Cuza look around the corner of the hallway. They sigh with relief when they see that you two aren't there. 

"Looks like we lost them," Cuza says. 

"Lost who?" You ask. The boys scream and turn around to see both you and Clio standing there. They scream again before taking off running down the hallway. You and Clio both start laughing and then the two of you share a kiss. 

"Wonder what their problem is," you say, laughing.
