Chapter III

Zero looked through the window of his new room: Kaname's room. The servants had brought his stuff and he had already settled there. However, he had not been able to start classes yet. His husband was not sure whether if he continued hiding his condition or otherwise to show it. If kept in his condition, Seiren would have to go to the sun dorms and modify the memory of all the day class students with the exception of Yuki and Ichiru. Nevertheless, he did not know if it was too early for them to know the truth.

That is why Kaname let him choose after all it was Zero's mental state the one in danger if he reminded to continue hiding his true nature from himself. Besides Kaname had warned him if he decided to remain hidden, he would have to stay at the sun dorms and only been able to see the pureblood on holidays. To Zero it was a line that he did not want to go through again.

The door swung open smoothly and Zero heard Seiren silent steps approaching from behind.

"I'm sorry I entered without knocking, Zero-Sama but I need the answer right now" said the stoic vampire.

Zero did not take his eyes from the window, the sun was setting down and the other vampires had gone to class. If Seiren did it tonight, he may return to classes tomorrow "Do it"

"As you wish, Zero-Sama" The woman bowed and headed to the door ready to leave the room

"Seiren" Zero called turning away to face the vampire guard

"Yes, my Lord?"

"Who will be replacing me as prefect?" The carrier asked

"Cross-san has given the job to you brother, my Lord" The vampire replied in the same monotonous voice

Zero nodded. He had kind of guessed it but wanted the confirmation "During the night, if you have nothing to do, I would like you to keep an eye on Yuki, please"

" Of course, Zero-Sama"

"Thanks, you may leave"

Seiren left the room with a bow and Zero turned his gaze to the window. He ran a hand through his hair. He snorted in annoyance and picked his hair up braiding it to the side. He was tired of being cooped up and would like nothing more to go out and talk to Kaien but Kaname had ordered him not to leave, it was dangerous with his smell hanging around the school.

Besides, it had been days since he had gone to see Lily although Aidou had gone to watch her it seemed the mare had been restless.

Seriously, he needed fresh air now!

Suddenly he felt someone's arms encircle his waist while soft lips gently kissed his forehead the pureblood's hands began to undo his half-braid, running his fingers through the smooth silver hair.

"What are you thinking of?" Kaname's voice came in almost a whisper "You were lost in thoughts that did not even hear me enter"

"I'm sick of being locked up in here, that's all" the carrier replied turning around to face the pureblood "Can I seize the moment in which you enter the classrooms and go to see Kaien?" He asked his eyes looking expectantly at the pureblood.

Kaname stared at him earnestly and sighed. It was strange that Zero had not gone directly to the Chairman without asking for his opinion. Fortunately, the carrier knew the situation was quite complicated enough to be reckless. Kaname could swear that if he refused, the hunter would leave at least this time Kaname would be watching.

"All right" He answered resignedly.

Zero kissed him softly and grabbed a jacket from the closet. Kaname approached him and gave him his hooded cloak instead of the jacket.

"When you return it's possible that your brother is still making his rounds, unless you have dinner with Kaien wait for me to get you" Kaname told him

"I'll wait for you to come then" Zero half smiled.

"Have you decided yet?" The pureblood asked all of a sudden.

Zero nodded and smiled softly "I'm staying here"

"Good" Kaname smiled pleasantly, he was afraid that Zero would decided to leave "Leave through the steeple"

Zero approached the vampire and kissed him and Kaname hugged him by the waist "Yes, my Lord" the carrier replied with a smile.

Yuki tried to hold back the hysterical girls of the day class whom wanted to approach the door between cries and squeaks. There had already been three days since she was waiting yet there was not a clue where Zero was. After what happened in the Association, Zero disappeared out of the map and then Ichiru appeared out of nowhere and Chairman Cross decided to place him as a prefect, according to his father, his brother was on a mission

I'm scared...

She was not herself right now. Besides the prefect, never disappear for so long during a mission. Yuki was scared she was worried about Zero and about this dreams and hallucinations. The last days she had some flashbacks, short images that left her trembling, visions of blood. Then in one of her visions, there was Kaname-sempai. She wanted and needed to talk to him about that.

The doors slid open and the crazy cries began to shoving her back to reality. It seemed that Ichiru had contained the girls better than she had. It was until the end that she could contain them shortly. She caught a glimpse of Kaname-sempai and he smiled at her while passing by.

Kaname saw his sister, Zero was right the girl was very scared. However, he could not do anything at the moment just trying to calm her down with his usual smile and calm words. He turned his gaze to his recent brother –in-law. Ichiru stared at him seriously. The similarities between Zero and his brother were amazing, except for the hatred in the eyes of his husband.

They entered the classroom and Kaname sat down. Tomorrow morning before going to class, he would have to inform the others about the situation. Well when he refer to the others he was talking about his inner circle at least he should inform Kain and Ruka because Takuma and his cousin had not returned yet.

Kaien Cross was in his office looking at some notes of the Association. He was concerned about the report he recently sent to them, explaining that Zero had decided to stop being a hunter and live in his vampiric form. However, the president was not happy with the news.

The door swung open and he casted his eyes at the cloaked figure waiting at the entrance of his office, his senses altered slightly at the smell given off by this person. Soon he found out that said scent was very familiar and loved.

"Zero" He whispered

His adopted son pulled out the hood and left the coat on the chair. Kaien was able to observe his relaxed expression and the tiny smile he gave to him. He had never seen Zero smile at least not in the last four years and to see him this quiet was strange and somehow relaxing.

"Chairman" The carrier approached the table and sat down

"Won't you give me a hug?" For the first time in a while, Kaien was getting sentimental without joking and he actually wanted a hug. Although Zero may not see him as a father that did not mean Kaien loved him as a real son.

Zero sighed and rose from the chair and went to Cross. The former hunter hugged him and stroked his head. Zero was a little uncomfortable with the hug but deep inside he felt at ease with the old man holding him close.

"I'm so sorry, son" He whispered brokenly. Zero could not tell if the older was sobbing or just joking "If I had realized earlier you would not have suffered so much"

"I am fine now and that is what matters" Zero replied as he corresponded to the embrace.

Kaien smiled and wiped the tears from his cheeks. Then he took Zero's face in his hands and smiled "Look how beautiful you are"

Zero frowned "I'm not a woman, Cross"

"Ow! Call me daddy" He said hugging him again at his own way.

"Kaien!" Zero shouted feeling his body suffocated by the hug

"Sorry" Cross said and released him with a sly smile "I was so worried about you and I got carried away"

Zero sighed and let the director kiss him on the forehead. Normally he would not allow such behavior but now it felt good to be in the arms of Kaien Cross, despite his eccentricities.

"Would you like some tea?" The chairman asked taking a seat on the couch in the living room while taking Zero's hand leading him to sit with him.

"Thank you" He shook his head "I was tired of being cooped up and I took the moment where Yuki and Ichiru were at the entrance to sneak up.

"I'm glad you came to see me" Kaien said with a smile

"Seiren is in charge for tonight and she will handle everything" Zero commented "I'll start tomorrow"

"The night classes follow a different schedule, I hope you do not have difficulties" Kaien said in a worried tone

"With what little remains to graduate I do not think that" Zero smiled

"Yuki is also worried about you. I told her you were on a mission" the chairman explained "Telling the truth is up to you"

"Not until Kaname returns her memories. We won't tell her anything at least nothing about our relationship" Zero replied with concern clear in his voice "She loves him! Once she regains her memories it will be easier to deal with"

"She will remember their engagement" Kaien said "I do not know if it's a good idea"

"It's better than telling her now" replied Zero "Yuki is too scared right now to add her the marriage of the person she loves"

"Well" Kaien sighed in resignation and then a mischievous smile showed o his face "When are you and Kaname going to make me Grandpa?"

"Kaien!" Zero shouted his face turning as red as a tomato.

"Oh come on Zero, you are married, it is normal that you have children" Kaien countered

"It's too early for that, we have not brought it up and I only have seventeen years old" Zero replied his flush never leaving his face.

Kaien smiled and kissed the hand of the young man. He observed how his long silver hair fell straight on his shoulders and back. He rose from his seat and went to the bathroom he took a small brush and one of his tapes.

"Let me fix your hair" The former hunter said as he started to brush it "Does not bother you? He asked referring to the long hair he was happily combing.

"That's why I cut it every morning" Zero replied in annoyance "I have braided it before but Kaname seems not to like it"

"I do" Kaien smiled and started to braid the silver strands.

Kaname was leaving class and went towards the principal's office. Seiren had notified him that Yuki was already asleep with her roommate in their room. He went through the hallway leading to the offices and stopped at the feeling of being followed.

"What do you want Kiryuu-Kun?" He asked diplomatically

"I had not had the pleasure to meet you yet, Kuran-sempai" Ichiru drew out his sword. They had given him directions but he felt like harming the pureblood.

"Put that sword away Kiyruu-Kun, I would not like to hurt you" He knew despite all the things Ichiru had done, Zero would suffer if his twin die "I could get you out of the way if I was interested, but that's not the case "

"Won't you make me a piece in your chess board?" Ichiru jumped with sword in hand and with surprising speed for a human. He tried to hurt Kaname but the pureblood was able to avoid the blow and grabbed the wrist of the youngest pressing it hard, causing the human to writhe in pain.

"Maybe your health has improve with the blood of Hio-San but you are still very fragile Ichiru-kun" The pureblood replied smoothly "Besides you are already on the board" The pureblood smirked.

Ichiru's face denoted anger and Kaname could not help but return to appreciate the resemblance between Zero and his twin though the face of his partner was painted with pain. He took the sword away and threw it to the floor pressing his wrist hard without breaking it. Ichiru moaned in pain but still did not let go.

"What's going on here?" Zero exclaimed while approaching the scene

He had felt Kaname close and altered. Zero took a chance, telling Kaien that Kaname was already waiting for him outside the house

Ichiru turned his eyes to his brother and his eyes opened wide at the sight before him. The last time he saw his brother he did not have his hair that long. The boy stopped struggling when the pureblood released him and headed to his brother with a frown.

"You should not have let the office" Kaname scolded

"I felt you were troubled and then the fight" He answered casually

The new prefect picked up his sword. His eyes traveled his brother's cloaked figure. Was that the reason he had not seen him before? He stopped at Zero's neck and stared at the recent bite marks on it. Then he watched as the two vampires talked between whispers. Zero's smell was different. If it were not for Shizuka's blood and the effects it had on him he would never have noticed.

"Zero-Kun is very special. I did not let him alive only because you asked me to Ichiru! Your brother will carry the power and no one has noticed it yet. But the truth is shown on his neck like a neon sign"

Shizuka's voice echoed in his head like a mantra. He had never understood her words nor had paid them attention. He was too angry with Zero. Shizuka's preference made him itchy. Then he heard the twins curse although his brother had never wanted to hurt him, he could not help but feel hurt.

He watched the two vampires, who seemed to be discussing in hushed tones as if they had forgotten about him. Kuran moved his hand pushing away a few strands of hair from his brother's face and placing them behind his ear. That surprised him entirely and he felt like he was in an episode of the Twilight Zone.

He observed Zero's tattoo, the seal that held his thirst as a way of control and the drawing seemed familiar, like the drawings Shizuka made in her spare time. Well, it was the same design except that the center of the drawing, the blackheads were less prominent.

His neck...

Shizuka's voice sounded like a mantra over and over again. That was the mark of Shizuka and yet endured.

Black…

He clenched his fist to the point of leaving his knuckles white and moved his gaze to the trademark. He did not have to be a genius to know who had done it.

"You ...!" Ichiru exclaimed angrily

The two vampires turned their gaze to Ichiru who was looking at Kaname furiously.

"First Shizuka ... And now you want to snatch my brother away..." He added and once again he took his sword and drew it fast. He ran with a quick move and separated the two vampires, taking his brother by the arm and seating him behind.

"Ichiru!" Zero exclaimed

"No!" He roared with pure hatred and then went to the pureblood "I will not let you taint my brother with your filthy hands!"

Kaname realized what the younger of the twins was talking about, apparently he cared for his brother but his actions did not show anything clear "You are a little late for that" Kaname smiled smugly "Get out of the way" He warned "I would not like to see my husband mourn because you continue to act like an idiot"

Ichiru gritted his teeth in anger. He was willing to kill the pureblood although that was not a part of the plan. He did not want him close to his brother. Ichiru felt Zero's hand on his shoulder and a kiss on his cheek, something very out of character. Yet he remembered when they were younger and Zero always protected him. The vampire grabbed his sword and Ichiru slowly released it. Then everything went black.

"I never imagined him that he was going to react that way" Zero declared and took the silver strands away from his forehead.

"Deep down, he still loves you. If not, he would not have let Shizuka kill you when she had the opportunity" Kaname stated "Do you want me to erase his memories?"

"Yeah, I'll have to cover my tattoo better. He has noticed way too fast" He looked at his brother in Kaname's arms as he modified his memories "Let him in his room, Kaien told me that he gave him my old room" Zero suggested

Kaname nodded taking the body of his brother-in-law and followed Zero through the halls. They left Ichiru lying on the bed and went back to their rooms.

Okay so here is the 3rd chapter I'm sorry for the delay.
