Zero walked in to his room and sat down on the bed. His room was nearly empty except for his night stand and bed. He walked over to the bathroom and stared at himself in front of the mirror. He opened a small black box with a red crest on it. Inside, he took out a tablet of blood. He popped it in his mouth but then started to cough it up. He fell to the ground holding onto the sink with one of his hands. He put the other hand over his mouth and started breathing heavily.
"God damn!" He cursed and closed his eyes to see nothing but the darkness. He opened his eyes once again and his eye color was no longer lavender; but red.
He got up and left his room staggering. Walking around the school he kept saying in a low voice, "Yuki... Yuki."
Trying to hold his thirst he held his neck and then dropped to the floor on his knees. His fangs showing and his eyes glowing dark red. One hand around his throat and the other on the floor to keep him from collapsing. His vision was blurring but then he noticed someone in front of him.
"Yuki." He whispered looking at the figure in front of him.
He couldn't see very well but he could recognize her blood. The figure bent down and opened up their collar. Zero went towards the pure blood in front of him and licked their neck. 'Her neck taste sweeter than usual.' He thought. Then he bit down as hard as he could and started to drink. He felt the person flinch and hadn't realized that he was draining her of her blood.
"Sorry." He said moving away.
The figure then just took the back of his head and moved it towards them into a hug. Zero hugged back and felt the warmness and the softness of the person. He then passed out due to being drunk of blood. He swayed for a moment and then tipped over. About to hit the floor she caught him by the head and waist and carried him to his room.
The next day Zero woke up refreshed once in his life. He sat up on his bed and stretched his arms. He smiled at this amazing feeling and sighed with relief. 'It must be because of Yuki's blood from last night.' He thought. He walked to principal Kaien's office to see her. He opened the door and saw her drinking tea with her adopted father. She was wearing a white trench coat buttoned all the way up to her chin and was wearing brown boots and black leggings.
"Zero!" She exclaimed with a big smile on her face. Even though she was a pure blood, he still seemed like the usual Yuki to him except with longer hair. He looked at her with an apologetic expression which made Yuki's smile fade.
"Sorry Yuki." He apologized with a low voice.
"For what?" She asked in a confused tone.
"For yesterday, you know I drank your blood and accidentally drank too much."
" What are you talking about? I didn't see you all day yesterday."
"What do you mean? I remember precisely that I drank from your blood." Zero said with a positive voice.
"That's impossible." Said Kaien. "Yuki was with me all day picking out what dish I should make for dinner, Kiryu."
"It takes that long to think of what to make?" Zero asked in disbelief and criticizing his adopted father.
"Hey! It took me a long time to decide and cook it." Kaien said crying in his corner.
"Whatever."
He then focused his attention on the blood situation. His eyebrows creased together and was very confused. He was positive that he drank Yuki's blood, or at least it tasted like her's. If he didn't drink from Yuki then who did he drink from?
