"You're mine alone"

When Sigmund heard it, he laughed. "I thought you're not that kind of Master," he grabbed her shoulders and pushed her lightly, making her loosen her embrace. "Is there something on your mind again?"

"I just thought I'd thank you for everything you did for me."

"What are you saying, you birdbrain? You summoned the Great Vampire, Sigmund. Of course, I can do anything for you," Sigmund then gave a serious look. "Besides, you promised me. Once you've gotten stronger, you will help me find what happened in the Silverblade Castle and why I was accused of killing the royal family. You haven't forgotten, right?"

Ivory nodded at him, "I will do my best so that I can help you."

He patted her head, "And once you've become a hero and a strong Master, you will not have a hard time convincing your sister to go back home. I will help you in that matter as well."

She gave him a smile and led him to sit on the bed. She placed her hand in front of his mouth, "As a thank you, you can drink more blood from me."

"How enticing…" Sigmund grabbed her wrist and chuckled. "But why will I bite your hand if you're exposing your bare skin like that?" He panned his sight from her head to her toes.

Ivory turned beet red, "Where do you want to bite me then?"

The Vampire smirked at his Master's question and pulled her onto her lap. With an arm wrapped around her as support, he bit her wildly and sucked her blood in different parts of her body.

Ivory would always blush intensely whenever he would sometimes pause and stare at her. Sigmund, feeling elated seeing his bite marks all over her, would whisper in a deep voice, "You're mine alone…" before sinking his fangs into her flesh, whilst Ivory would tighten her grip to his shoulders, trembling and letting out soft moans.

He got so absorbed with the act and how delicious her blood was that he repeatedly bit and sucked her the whole afternoon until she passed out on his arm.

"Shit. I overdid it," Sigmund muttered, embracing Ivory with one hand as she slept peacefully on his chest. He moved close to the wall and leaned his back against it before pulling the sheets to cover her back, making sure she wouldn't feel cold.

...

Ivory woke up at dawn, and she widened her eyes when she saw her arms wrapped around Sigmund.

"Why are you surprised?" Sigmund cocked a brow. "You told me I'd be your body pillow."

"Yes, but-" She then noticed the bite marks on her arms and legs, "These…! Sigmund, you're so mean!"

"You gave me the freedom to bite you anywhere, remember? Don't act so surprised."

"But I never told you to bite everywhere!" She playfully hit his arm, "How will I hide these marks? It would be troublesome if they knew you're a Vampire Class…"

"You've already rested. Why don't you try to heal yourself?" He suggested, even though at the back of his mind, he wanted her to retain his bitemarks.

Ivory closed her eyes, and she tried to concentrate. She recalled the lessons that she had on focusing her mana, and she tried to channel the mana onto the surface of her skin.

But nothing happened.

"What's the matter?" Sigmund asked when she opened her eyes.

"Uhm… I can't do it…"

Sigmund smirked, "Wear something conservative later. From now on, I will not allow you to show too much of your skin."

"Ehhh? But-"

He pulled her back into his arms and whispered in a deep voice, "You'll catch a cold, dimwit."

Ivory couldn't do anything since her possessive Servant did whatever he wished. Sigmund stroked her long silky hair until she fell asleep once again.

...

And so when they went to class the next day, Ivory wore a red and blue green long-sleeved checkered turtleneck sweater and a long gray pleated skirt.

"Eh? Isn't it too early for winter?" Arcea uttered as soon as she saw her in the weird outfit. "I think you need to improve your wardrobe. How about I give you some off-shoulder dresses? You looked really gorgeous on Lucius' birthday!"

Peeking at Sigmund's annoyed expression, Ivory replied, "Uhh, no. I'm okay, Arcea, thank you."

Seeing an Educator enter the room, Lucius told them, "Let's take our seats. Educator Wallace is here."

"Everyone, settle down and listen carefully," Educator Wallace said, and the students kept quiet. "Today, you will all learn an advanced Water magic technique called Conversion magic."

The eighteen students of the Blue Gem section became excited. Ivory glanced at Sigmund, and he nodded at her. Finally, she could learn the magic technique she had been doing unconsciously.

The whole class proceeded to the coliseum where eighteen buckets of water were prepared for each student.

The Educator explained, "Conversion magic is changing the phase of water, meaning turning water into ice or vapor. You can even turn it into fog."

The students seemed confident, especially Ivory, who was already familiar with the idea of Conversion magic.

"You have the whole day to do it, but here is the challenge. You must never use other elements to convert the water in your bucket. That means… do not boil it using fire. Focus the mana on your magic weapons. Incorporate and concentrate on the Water element… make it evaporate and condense, and..."

The more the Educator explained further, the more they got nervous.

After explaining, he told them, "You won't go home until you convert the whole bucket of water into fog."

And so, they all started trying Conversion magic. Educator Wallace and his Servant walked around to see if anyone needed advice with their magic control. His Black Eight-tailed Fox Spirit Servant, Furrene, had skin as dark as coal, ears like a fox's, and curvy body like a human's. Aside from the fancy knee-long black leather dress, she was wearing a furry robe of black and red color.

Both of them made sure that nobody would use a different kind of element aside from Water.

"I don't get it…" Ivory sighed. She sat down on the cold, stone floor. "Tell me, Sigmund. Did I really do it before?"

"Yes, you did."

She then heard one of her classmates shout, "Yay! I did it!"

They finished the task one by one. Lucius finished the earliest before lunch time, while Arcea finished around early in the afternoon. Slowly, the eighteen students were reduced to fifteen, then five.

And before sunset, only two of them remained.

"Still don't get it?" Sigmund asked her. "How about I help-"

But even before he could get near his Master, Furrene shot a ball of fire on his feet.

"Hey!"

"That is not allowed," she told him, and Educator Wallace chuckled when he saw him surprised with the ball of fire.

"Fine…" he crossed his arms.

"You can do it, Master Zephie!" The other student's Butterfly Nymph Servant yelled. He's a tall and muscular man with antennae on each side of his head and huge butterfly wings.

The Servant then noticed Sigmund, staring at his Master with furrowed eyebrows. He stood beside him and said, "Why don't you cheer for your Master as well?"

But Sigmund preferred to cheer for his Master secretly. Even though he knew that she's doing the best that she could, he just stood there and stared at her, because it's not in his personality to openly voice out how much he cared for her. In an annoyed face, he responded to the friendly Nymph:

"Nah... I'm not a sweet Servant."
