A/N: New Chapter! Someone asked me to continue, and I felt rather obliged after being away for quite some time. I didn't know people were still reading this enthusiastically and hoped me to continue. Well, enjoy!

"Okay okay. I need to be serious here." Guren straightened himself and rubbed his temple. "This was all some kind of weird hallucination." He sighed. It definitely wasn't. How had he not noticed this before? "Now that I think about it…." Guren had often seen Yuu in the bathroom, but actually never saw him naked before. Feeling his heartbeat rise as he thought back at the view from a few minutes ago, he punched the wall.

"Crap! What should I do now? Can't just walk back in." He stood there, contemplating for a few more minutes before deciding to walk back in and pretending nothing had happened. "I still have to take a shower anyway." He only then noticed he was still half naked in the hallway and people were looking at him weirdly.

As soon as the black haired Lieutenant Colonel stepped inside, his eyes fell on Yuu. She was just finished getting dressed. "Hey." She started. "Hey." He replied. Guren reluctantly walked over to his locker and stared at its content. No words were uttered. Yuu eventually left and Guren quickly grabbed his stuff and walked over to the showers.
"It was you wasn't it?" Suddenly, he heard a voice behind him.
"Yikes!" Guren jumped and turned around, shocked to hear the sudden voice. Yuu stood there, staring at him. Guren was practically naked, so he turned around while looking back at the black haired girl.
"That already confirms it." She nodded at his movement. Guren sighed.
"I…"
"You're actually the second to notice."
"I am?"
"Everyone else just sees me… as a boy." Yuu showed him a wry smile.
"But what I just saw…." Yuu started to unbutton her uniform. "H-hey! You don't have to show me again."
"N-no It's not like-" Yuu struggled with her words. Then a demon horn sprouted from her head. Guren noticed her sword behind her on the wooden bench. "I guess I'm kind of done being seen as a boy." Guren tried to sprint past her, but he failed miserably when she reached out and grabbed him by his throat.
Her voice was a bit lower than usual. Guren was helpless when Yuu, powered up by her demon, pressed him against the cold floor. She turned on the water and let the water cascade onto her victim. "Yuu! Stop it! Don't let the demon take over-" Guren tried to stand up, but was knocked down again when she held him down, her boot pressing down on the side of his face.

"Guh!" Guren tasted the iron on his lips. He tried to resist, but Yuu had the upper hand. The fact that he was naked didn't help either. The water dulled his senses and Yuu was too strong for him when she used her belt to tie his wrists to the shower post. What happened next wasn't even in his wildest dreams. Or nightmares for that matter. Yuu pulled his hair back and pressed her lips hard on his, her tongue searching for the blood in his mouth. Guren whined in response, his mind running overtime to figure out a way to get away from his predicament.

"Yuu! Yuichiro! Come back!" The demon however, had other plans.
Guren cried out in surprise when she touched him. His cheeks were burning as his body reacted.
"Your reactions to my fingers are lovely Guren."
"This can't- Ah!" At his plea, Yuu froze.
"Grr…." Guren tugged at his restraints. This was an opening he could not permit to miss. The water had stopped. Her eyes scanned him before she grabbed her head. "Uhhh!" The horn retracted slowly.

Guren managed to free himself. Yuu was almost back to normal. She panted heavily. "S-sorry.." Yuu fell on her knees before fainting, tears falling down on the cold bathroom floor. The wet floor made Yuu's uniform rather see-through, and Guren sighed heavily. His heart was beating loudly. Eventually, he managed to stand up and get dressed again. Then he carried the girl to her room.

That evening, Guren had been sitting behind his desk for almost an hour. Staring into the distance and thinking about what had happened. Yuu was in her bed. "What the fuck should I do?" Many weird things had happened during his war against the vampires, but this was new. Then he blamed himself.
"He- Fuck- She's your pupil you idiot?! How could you not notice?!" He shook his head. "Nothing I can do about it anymore anyway." He stood up, his heartbeat slowly rising. He had to see her and talk this out. Before it got worse. He turned around again. "Not now you fool." Guren sat back in his chair. Tomorrow, he would talk it out. Not after the little event.

The black haired officer couldn't help but remember laying helplessly on a cold bathroom floor. Never had he been so embarrassed. A blush crept up his cheeks. The sword on his hip laughed in response, a purple haired woman appearing in front of him.
"How hilarious~ My little Guren, excited by a little rough play." He simply shook his head.
"Think whatever you like."
"Oh but I do. Now that you know that she's a girl, I'm sure I will only take a little time before you fall in love."
"Whatever." She vanished, appearing behind him and hung on his shoulders.
"Guren~."
"What do you want."
"I want you to be honest with yourself. I can see your memories, your thoughts." Suddenly, Guren had enough. He suppressed his demon and growled.
"Tomorrow, I'll talk this out and that's the end of it. I'm not into little girls."
"Liar."
"Get lost."

The next day was as difficult as Guren had expected. He was reading in Yuu's room until she would wake up. He did not sleep a wink that night. "Good morning." He tried to say expressionless, but failed, if only a little. His eye twitched. Yuu just stared at the ceiling.
"Could you…. explain what exactly happened Guren? I had a dream… But there's no way that that could have happened."
"Unfortunately for us both, that is exactly what happened." Guren closed his book. Yuu shot up. Guren definitely noticed a girl's chest.

"I'm sorry for not noticing that you were a girl. Apparently, you've been having a hard time, and as your supervisor, I should have noticed." Supervisor? That was cold. Guren mentally hit himself.
"Am I cursed?"
"Don't be so dramatic. But perhaps you're right, I don't know. Did Kureto say anything?"
"No, but-"
"You're close to him right?"
"He's just… trying to help me I think." A silence fell. They did not look at each other. "...I'm sorry." Yuu said, just before Guren would have. "I attacked you. I can't really remember but it must've been horrible."
"It's okay. I've had worse."
"You don't have to be tough." Yuu replied, staring at him. Guren froze at her words.
"I'm not-"
"I'm serious Guren. I feel really bad about it."
"It's okay." The black haired man replied quickly. Yuu closed her mouth. An awkward silence fell.
"Guren… I want things to be back the way they were."
"That's...impossible." Yuu bit her lip. "But don't worry, we'll figure something out."

Enjoyed it and you're glad I finally posted an update? Let me know! Moreover, for the next chapter I'm open for suggestions, requests etc. Anything's possible so don't hesitate :)
