Vampire Knight: Crimson Passion

Chapter 4: Weakness

Yuna had ran to the Headmaster's office to check if her handbag was still there. But it wasn't and she realised Zero had taken it to his room already. She asked what room number her childhood friend was staying in, he gave her a spare key and rushed to the Sun Dormitory. She ran up the stairs and finally got to the room. She entered and found her bags, as she went through her handbag she found her Ferrous Sulphate tablets were empty. She realised that they were her last ones. She knew it would take 3-4 more days to reorder her tablets and another 2 days to get them.

The young woman went back to the Headmaster and saw Yuki and Zero there. The silver haired teen look like he was bitching about something but then they turned around to see Yuna, who had beads of sweat rolling down her forehead. She breathing heavily and took some time to catch her breath.

"Is everything alright, Yuna?" The Headmaster asked.

"I have a problem." She stated.

"Dear, has mother nature visited again? Cuz Yuki has some spare…you know." He murmured quite seriously. Zero's eyes widened as he turned to his childhood friend, Yuki covered her face and gasped and Yuna's whole face turned beet red out of embarrassment.

"N-no way!" She shouted and exhaled trying to calm down. "My Ferrous Sulphate tablets, they're finished and I have to wait almost a week to get them."

"The tablets for your iron deficiency is finished? Hm, well there's nothing we can do but give you food rich in iron." The Headmaster pushed his glasses to the bridge of his nose. "I want you to take it easy for the meanwhile, Yuna. I'll try to contact the pharmacy and get them as quickly as possible."

"Thank you…" Yuna smiled sweetly.

"Wait, what about the blood tablets?" Zero asked.

"What are blood tablets?" She asked.

"They're a type of substitute for blood which vampires use instead of hunting for blood." Kaien answered.

"No way!" She yelled. "I am not drinking it, that's fucking disgusting."

"Well, they're not as effective as your Ferrous Sulphate tablets. So I highly recommend you don't drink them." Kaien stated. "Yuna, please try to be careful okay. If you don't feel well, make sure you head back here."

"Damn, Uncle. I'll be okay, you don't need to worry too much. I'm not gonna die." She said. "I'm strong, don't worry."

"You sure, Yuna?" Yuki asked.

"Yes, don't worry! Look, I'm gonna go back to patrols around the main building. Again, I'll be fine so don't worry." She reassured them and exited the room.

She walked outside and headed towards the main building. As she patrolled the building, the young woman smoked 2 cigarettes as she made her way round the school.

As she walked through the corridors by herself, she began to remember the night that Pureblood turned her mother into a vampire. She was protecting her and told her to hide in the closet. And when Yuna's mother refused to tell the vampire where her daughter was, she got bitten. She didn't get bitten so easily, of course she fought back but he was way stronger. The young girl saw all of this through a gap in the closet and he ran off just before her father rushed into the room.

This memory gave her a headache and tears fell down her cheeks. She began to walk slowly because she felt dizzy, her hands and feet were very cold and she felt really weak. She took deep breaths and decided to make her way back to Headmaster's office.

As she turned around the corner, she saw Kaname and Takuma walked towards her. Her eyes widened and she tried to look as normal as she could. She stood up straight and walked carefully.

"Why, hello Yuna." Kaname smiled.

"Y-you 2 should be back in class." She mumbled.

"We're on our 15 minute break. It's nice seeing you again, Miss Yagari." The hunter had heard of this vampire and had met him before too.

He was the vice president of the Night Class and the grandson of the Vampire Council. He was actually her good friend and the only vampire she liked. Takuma was so cheerful and caring, not to mention un-vampire like. Yuna just smiled slightly with a small laugh.

"How many times have I told you, Takuma…" She took a deep breath. "Just call me Yuna."

"I always forget." The vampire laughed nervously whilst scratching the back of his head.

"Yuna, are you feeling alright. You look quite pale." Kaname stated.

"I'm fine, I'm just a little tired." She lied and he could tell.

He raised his hand and she instantly grabbed his wrist. Her hand was icy cold and her grip was extremely weak, he had expected a stronger grip. She knew he'd pick up on that and let go immediately.

"Yuna, you look really unwell!" Takuma exclaimed.

"I-I'm…" Yuna's blinked slowly.

The young woman's knees buckled and she felt like her head was spinning. Just as she was about to fall to the ground, Kaname caught her.

"L-let go of me…" Yuna tried to sound intimidating but the tone of her voice was weak and slow.

"You can't walk, not in this condition." Takuma said.

"We need to check your heartbeat." Kaname stated and placed his hand on the left side of her chest. His eyebrows furrowed together and she turned to him.

"I have dextrocardia." His eyes widened when he heard this. His first love, she had that condition too, with her heart being on the right side not the left. His hand slowly moved to the right and he felt her heartbeat was very fast and irregular.

"Takuma, you return to class. I'll take Yuna to the Headmaster's office." The brown haired pureblood stated and he left. Kaname picked the young vampire hunter up with ease and she growled under her breath.

"I swear to god…if you do something edgy I will kill you." She said as he walked outside.

"I ensure you no such thing will happen. I have manners and standards, especially around a lovely lady like you." He smiled and she cringed.

"Just shut up and walk faster." She growled.

Kaname got to the beautiful fountain and leaned Yuna closer to the water. It was freshwater and she drank some of it. He then sat her down against the fountain and knelt down next to her.

"Now take deep breaths." He said gently.

The young woman couldn't believe a Pureblood was helping her in her moment of weakness. She did as she was told and then felt a little better but still a little weak.

"Do you feel better?" He asked and she nodded. "Do you know why this happened by any chance?" She glared at him and he stared at her curiously.

"I have a very low iron deficiency and my tablets are finished. I won't be getting them for almost a week."

"Is there any way I can help? Takuma's family owns a pharmaceutical company, so I could get your tablets quickly." Yuna's eyes widened; she completely forgot about that.

"This is only one favour I will ask from you. Don't expect another." She said and he smiled.

"I will only get your tablets under one condition." He stated.

"I am NOT giving you my blood." She growled and he laughed at this. She turned to him with a dark look which make him stop, but nonetheless he still had that gleam on his face.

"Only if you don't return the favour. I don't want anything in return." He said.

"That's fine with me." She shrugged nonchalantly. "I think it's time for you to return to your classes, Kuran." He nodded in agreement whilst standing up.

"Well, I will see you soon. Make sure you rest properly, okay?" Kaname stated.

"Hm…" She mumbled.

"Have a lovely night." The vampire said and he left.

"Don't tell me your befriending the Pureblood." Yuna heard Zero's voice as he walked up to her.

"Didn't anyone tell you it's rude to eavesdrop?" She asked with crossed arms. "Besides I was brought here against my will. I almost fainted in the corridor and he took me here to give me water." She said clearly irritated by the situation she was in.

"Are you okay?" The silver haired teen asked worriedly as he sat next to her. "Come on, let's go to our room, I think it's best that you lie down."

"But what about prefect duties?" She asked.

"Don't worry, Yuki's got us covered." He said.

"But…"

"No more buts. You okay to walk?" He interrupted her.

"Yeah." She answered.

The brown haired teen stood up and as she took a step forward, her knees buckled again and she fell to the side. Zero caught her with his hands on her shoulders and she blushed.

"Get on my back." He said.

"Do I have to?" She asked sheepishly and he glared at her. "Okay, okay!" Yuna got on her childhood friend's back and he carried her on his back as he started walking back to the Day Dorms.

"You know I'm still taller than you. Remember when you used to say you'd be taller once we're grown up?" She teased with a smirk.

"I have 1 more year." He stated. "Just you wait I'll be taller than you in no time."

"But I'll still be stronger." She laughed.

"Well I can tell you're heavier. What do you do, sit on vampires till they can't breathe?" She pouted and punched his head.

"Hey, shut the fuck up, before I beat you up." She threatened him.

"I swear that came out more cute than threatening." He mumbled and she blushed.

"Did you just call me cute?" She asked with a huge grin on her face. "Oh my, I didn't know I was cute."

"Shut it before I drop you down." He growled.

"Well THAT sounded like you were flustered." She replied smugly.

"No I'm not." Zero lied.

"Your cheeks are red like roses." Yuna giggled and sighed. She rested her head on the side of his and looked at him. "You had the hugest crush on me on kids, remember?" He fell quiet for a few minutes then gulped.

"How did you know about that?" He asked.

"It was really obvious. You were always trying to impress me and whenever you saw me your face was the colour of a tomato!" She exclaimed. "It was so cute, you know. You and Kaito would always compete for my attention."

"I remember when he would always bully me." He mumbled. "I always lost against him, but you were always there to cheer me up, or treat my bruises and cuts."

"Back then, Kaito lived with dad and I, so he was more of a brother. You were the closest best friend I had." She said as she wrapped her arms around his neck.

"It's nice to hear that…" He smiled.

"Especially after my mom died, you were always there for me when I needed you." She whispered.

They got to their room and Yuna hopped off Zero's back. She ran over to her suitcase, opened it up and took out some clothes for her to changed into, face wash and her toothbrush. Her roomie told her to get changed in the bathroom and she went in. The young woman got changed into an oversized jumped and jogging bottoms. She washed her face, brushed her hair and tied her hair up in a ponytail.

She came out whilst scratching her head and yawning. She crawled into a bed and just as her childhood friend was about to tell her it was his bed, she had already fallen asleep. Yuna had a really long day and she was tired.

Zero smiled at this and covered her up with the sheets. He knelt down and placed his hand on her cheek whilst staring at her gently. Then his throat started to burn, he needed to quench his thirst so bad. For a split second he glanced at Yuna's throat and imagined her blood. The silver haired teen shook his head and snapped out of it. There was no way he'd do it, she was his childhood friend, she was the second ranked vampire hunter in the association, she was anaemic and she was his weakness.
