I trust Kaname but how long do I need to wait for the truth?

Mana patrolled the school campus, flexing her gloved hands in agitation. She had seen suspicious figures but had yet to completely find them. She sighed and turned back towards the school.

Something didn't feel right. She could imagine her imaginary hackles raised. Something was off and she felt jumpy. Seriously if this aura wasn't fixed any time soon, she might…

"Mana."

Mana leapt and snatched Pearl Beauty out from under her skirt. She cracked her out and braced for an attack.

She relaxed when she saw Kaname in the shadows and let out a sigh of relief.

"You startled me," she said as she withdrew Pearl Beauty.

She was about to slide her back into her strap but hesitated. Kaname had a spot of blood on his lips.

"Kana, what's going on?" she asked shakily.

Kaname stepped out into the moonlight.

"I need you to trust me, Mana," he said.

"Kana, whose blood is that?"

Kaname noticed the blood on his lips and wiped it away.

"Mana, I need your trust."

Mana swallowed and nodded.

"Of course, I trust you."

"Thank you…" Kaname sighed as he reached out for her.

"Mana, no!"

Mana turned around and saw Zero running towards them.

"It's a trap!"

Mana gasped as Kaname flung his arms around her.

I surely don't have any reason to not trust him, right?

Mana remembered being in Kaname's room and being cradled in his embrace. She was rocked whilst he peppered kisses on her head.

"Promise me," he whispered. "Promise you won't hate me."

Mana shuffled out of his arms and straddled him. She cupped his face and made eye contact.

"I could never hate you," she said.

Kaname's lips parted as he stared up at her.

"Mana, I want to tell you everything," he said. "But you must allow me one thing and I promise, you will know everything."

Mana's stomach lurched.

"What is it?" she asked and she pulled away slightly when Kaname's eyes flared red.

"Let me bite you," he whispered. "Let me turn you into one of us."

Mana parted her lips. A furious knock on the door interrupted her.

"Kuran, don't!"

Mana turned to the door. Kaname turned her to face him.

"Mana, please."

"He's already turned Yuki! Don't let him come near you!"

Mana's heart dropped.

"You…bit Yuki?" she whispered.

"She was becoming violent, Mana. I had to before she did something she regretted."

Kaname clutched onto her.

"Mana, I want to share an extended lifetime with you. Become one of us and spend eternity with me."

Mana glanced at the door when Zero continued his attempts to kick it down. She raised her shaky hands and unbuttoned her blouse. Kaname breathed in as she exposed her neck.

"I trust you," she whispered.

Kaname cupped the back of her neck and brought her forward.

"Mana!" Zero yelled.

Kaname was so gentle and loving. And he lived up to his promise. He told me everything.

Mana rested her head in Kaname's lap. Kaname petted her hair.

"So, you're my brother," Mana murmured.

Kaname hesitated in his stroking. He tangled his fingers into her locks, gently tugging.

"It must have been uncomfortable to proclaim your love."

"It wasn't," Kaname shook his head. "We are engaged after all."

Mana sat up and looked at him in bewilderment.

"Come again?" she whispered.

"It isn't uncommon for Pureblood families to interbreed to keep the blood pure," Kaname explained. "Our parents were siblings."

Mana withdrew, curling her legs into her chest and looking away.

"That's…weird."

Kaname sighed.

"When Rido has been dealt with, I want us to get married. I have always felt this way."

Mana glanced at him.

"I'm sixteen. I'm a bit young to get married."

"What's stopping you?"

Kaname turned to her.

"You can still pursue your dreams. I'll just be by your side."

Mana sighed and ran her hands through her hair.

"Kana-nii," she said. "What about Yuki? She's in love with you too."

"But I love you, Mana. And you've proclaimed your love for me too."

"But that was before I found out you were my brother!"

Kaname clenched his fists. He glanced at the time and sighed.

"I have to leave."

Mana sharply turned her head towards him.

"I want you to stay safe so Seiren will be with you whilst I'm gone."

He stood up and approached her. He took her chin and leaned in. Mana pulled away slightly. Kaname hesitated then kissed her forehead.

"I love you."

Everything around me is so conflicted. But at the end of the day, I love you, Kana-nii.
