A Liquid Inspiration
Summary: (A re-telling of Classroom of the Elite sparked by a certain conversation between Masterpiece and Professor.)
One day, Ayanokouji Kiyotaka receives a surprising invitation from his father, Ayanokouji Atsuomi, to join him for a drink. It was unusual for Kiyotaka, who normally wouldn't be summoned by his father without a hidden agenda.
That's why even the emotionless Kiyotaka was surprised when his father began to open up about his own experiences with love and relationships.
For the emotionally distant "masterpiece," this conversation is a rare moment of connection with his father, and it sparked a curiosity within him to explore the world of human relationships, to be more specific: romance and intimacy.
It was that spark that pushed Kiyotaka to demand something from his father:
"Father, teach me everything about human relationships."
This then begins a ripple that changes how Ayanokouji Kiyotaka would approach the world in the foreseeable future.

Vol. 1 Chapter 13 - Return to 'Normalcy'
Kushida Kikyō
After what felt like an eternity of reliving memories I had long wanted to suppress and never remember, I... was finally freed from the shackles that had bound me from the moment that I woke up. The lingering pain from the tightened ropes that once gripped my wrists and legs stayed with me, a chilling reminder of my confinement.
If there were one thing I believed I would never be capable of feeling, that would be the feeling of regret.
But I suppose, just like with most ignorant assumptions, the time would come wherein the fates decided to teach me a lesson about my naivety.
However, couldn't this lesson be taught in a gentler way?
I hesitated to move, my legs trembling from being bound for a couple of hours. The sound of my own labored breathing filled the room, echoing the pounding of my heart. Finally, I stood up from the chair I was formerly bound to and rubbed my sore wrists, which were still feeling the roughness of the ropes that held them earlier.
My tear-filled eyes wandered across the macabre-looking room, the terrifying events of earlier replaying bit by bit in my mind, making it difficult for me to breathe. The dim lighting cast eerie shadows on the walls. Soon, I let out an involuntary flinch as my eyes met the violet orbs of my tormentor, Tsubaki Yuki.
I... would rather not remember what had happened earlier, but that sinister grin on her otherwise gentle and immaculate face would be the source of my nightmares for years to come. I looked away quickly, not wanting to give her the satisfaction of seeing me afraid.
"Are you all right?"
I was interrupted in my thoughts when a cold, detached voice rang in my ears. I turned my head slightly and was met with the impassive face of Ayanokōji-kun, who was examining my face as if to see just how bad did I suffer.
Did... you enjoy seeing me like this, you sick fuck?
As my mind hurled a series of expletives toward the brown-haired boy, my tormentor's words rang back in my head.
"I would have let you go had you not been stupid enough to try to do something like that to Kiyotaka, you know? Maybe just blackmail, if I was feeling generous."
Her cheerful laughter followed those words, making me think like this was just a game for her.
Feeling helpless, I decided not to further aggravate my situation and attempt to be civil with Ayanokōji-kun.
"I... I'm sorry for earlier, Ayanokōji-kun."
"Do you mean it?"
Absolutely not, you fucking dipshit! But... what could I even do?
There was no escape for me.
My life in this school is now under the hands of Tsubaki Yuki, and I've come to realize that whatever I do now... would be futile.
"Y-Yes," I replied, my voice strained.
Ayanokōji-kun's eyes did not leave my own, letting out a deep sigh after a few moments.
Did he perhaps not believe me?
But I suppose that with what had just been revealed to me tonight, that might as well be the truth.
I hate this feeling of helplessness.
Why did I even have to endure something like this? Why couldn't I just live my ideal high school life?
This is your fault, Yuki... you fucking bitch!
I may not be able to get my revenge now, but you just watch. I'll be biding my time, and you better prepare for what I'll have in store.
"Just get some rest, Kushida. Chiaki will be guiding you along with what you need to do for tomorrow," Ayanokōji-kun replied, looking at that demon, who still had a sickly sweet smile on her face. "Since I doubt you'd be comfortable with Yuki's presence."
My face did not show it, but his words stunned me.
Why... why were you extending me that kind of courtesy?
And his eyes...
They may look impassive and uncaring, but upon closer examination, I could see that he was not comfortable with what had just happened to me. In fact, I heard him chiding Matsushita-san earlier for them going overboard.
No... no.
This was a trick.
If he actually cared, he would have stopped that demon when she began her assault on me.
Suppressing a sigh, I walked towards the door, readying myself to walk out of this hell and attempt to get some rest. However, my fear and anxiety had somehow crippled me at the moment as it looked as if I was shuffling towards the door instead of walking normally.
"Sleep well, Kikyō-chan~ Don't have any nightmares!"
My heart beat faster than it ever did upon once again hearing her cheery yet unnerving voice, reminding me once again of what I had to endure from her.
W-Why... why do you enjoy this so much, you demon?
Please... please let me rest easy just for tonight.
My thoughts seemed to have blanked as I did not notice Matsushita-san approaching me, facing me with a smile.
The brown-haired girl was carrying my bag, as well as another handbag that Ayanokōji-kun had ordered her to take.
"Let's go, Kushida-san," she said, gently taking in my arm with her and guiding me out of the room.
As the two of us exited the room, Matsushita-san let out a deep sigh.
"I... I apologize for what Yuki-chan did earlier," she suddenly said, facing me. "I did not even expect her to go that far. I was actually surprised to see you tied up when I came into the room."
"Then... why didn't you stop her?" I asked, trying not to sound accusatory.
"Stop... Yuki?" she asked, arching an eyebrow. "That's not something I'd advise anyone to do, Kushida-san. You were simply unlucky that you had somehow ticked her off," she added, her eyes showing none of their usual kindness.
I didn't know what to say. Matsushita-san was not wrong, but this level of misfortune was almost too much to bear.
What did I do to deserve this?
13.1
We walked down the dimly lit hallway, the faint scent of stale air hanging in the atmosphere. The muted sounds of our footsteps echoed off the walls, punctuating the silence that weighed heavily between us. The darkness seemed to envelop us like a shroud, and the chill in the air sent shivers down my spine. I could feel Matsushita-san's grip on my arm, steady yet cautious, as if she were afraid I might break.
With each step toward my dorm room, the weight of my thoughts intensified. My mind raced with unspoken questions about the twisted game I had become a pawn in. What kind of twisted game were they playing, and why did it have to be me? The bitter taste of humiliation clung to my tongue, and anger simmered beneath the surface like a fire desperate to be unleashed.
Matsushita-san opened the door to my room, the hinges creaking softly as it swung open. The familiar scent of my belongings filled my nostrils, providing a small sense of comfort amidst the chaos that had become my life.
"Here we are," Matsushita-san said softly, as she handed me my bag. "I'll be here with you for a while. I hope you don't mind."
I do mind... but considering all Matsushita-san did was trail me and help the demon accumulate her ammunition, I suppose I could pretend to be civil with her.
Well, it wasn't like I had a choice, don't I?
"It's fine," I murmured, not knowing what else to say. I could feel the exhaustion settling in, my body aching for the respite that sleep would provide.
Matsushita-san followed me inside and closed the door. She gestured towards the couch, and I obliged, sinking into the familiar cushions.
I sighed deeply, allowing my eyes to roam around my room—the pale blue curtains, the worn wooden bookshelf, the soft glow of my desk lamp—hoping the familiar sights would distract me from my recent ordeal, even if only briefly.
"Kushida-san," Matsushita-san called, opening the bag Ayanokōji-kun had given her. "This is what you're supposed to do. It's a lot to take in, but you need to do this."
"It's not like I have a choice, don't I?"
"You do have a choice," Matsushita-san replied. "To survive or to suffer."
Are you seriously pulling jokes now, you fucking side chick?
"Ah, my apologies. I'm just used to talking to Yuki-chan. Sometimes I get carried away," she said, her tone apologetic.
They seemed like two peas in a pod... just as I had expected.
As Matsushita-san explained the details of what the demon had shared earlier, my mind unwillingly returned to the events from hours ago.
My mind reimagined the jolt of icy water splashing against my face, the panic that surged through me when I realized I was bound to a chair with no hope of escape.
Her taunts, accompanied by the recordings of my venting sessions... and her promise to delete them all if I revealed the origins of my hidden self.
Initially, I thought Tsubaki Yuki might have been sincere.
After all, from the month I spent with her, I've noticed her do many things on a whim or just because she wanted to find out something. So I foolishly thought that if I had just obeyed, this nightmare would have ended, and I could prepare to plot my revenge against her.
But I couldn't just break... I had to show resistance...
Then she showed me her phone, displaying a screen that suggested she was about to send a recording of my outbursts to a group chat filled with influential class members like Hirata-kun and Karuizawa-san.
That was something I couldn't allow to happen, so I relented.
I revealed everything—from my secret blog to the class meltdown—and the demoness simply watched, seemingly amused by my confessions.
Her only response was a cold, heartless, "You're a dumbass."
But to my temporary relief, she did delete the recordings.
Then, in a cruel twist, Tsubaki Yuki shattered my hope, revealing that she had multiple copies of the recordings and that Matsushita-san had been the one recording everything. The air in the room became thick with betrayal, the sickly-sweet scent of deception enveloping me.
I felt utterly helpless, my heart sinking with the weight of the realization that I had given up one of my greatest secrets for nothing.
Tsubaki Yuki... is a demon masquerading in human form... the very embodiment of madness.
Her words continued to assault me, each syllable tearing away at my carefully constructed facade, stripping me down to my raw and vulnerable core.
Then, she offered me a way out...
And that was for me to fulfill five quests for her.
The first of them was the same one that Matsushita-san had been relaying for over the last 10 minutes.
I was brought back to the present by Matsushita-san's lilting voice. "Did you catch all of that, Kushida-san?" She asked.
"Yes. I got it..."
The mission?
To frame four second-year students of attempted assault... and to make my testimony authentic, Tsubaki Yuki blindfolded me, and before I knew it, the door opened. Within seconds, unwelcome hands roamed all over my body.
I wanted to squirm, to fight back... but I was paralyzed with fear.
So all I did... was cry.
It felt like an eternity, but it lasted for about five minutes or perhaps even longer. When the blindfold was removed, I felt like I had aged a decade.
A wave of self-disgust washed over me, even though I knew I had done nothing to warrant such a feeling.
The vile sensation of being violated by unseen hands...
The pain was unbearable.
But I was never a quitter... I would persevere, find an opening, and in time... exact my revenge on the devil.
"Here, have some water," Matsushita-san offered, handing me a glass. The cool condensation on the outside of the glass matched the chill I felt in my bones.
It seemed that while I was lost in my memories, Matsushita-san had fetched water for me.
I nodded in thanks and began drinking, the water providing temporary respite from the pain.
"Do you want another one?"
I nodded.
She returned with another glass, which I gratefully accepted.
A few minutes later, Matsushita-san stood up, her eyes looking sympathetic... encouraging even. "Kushida-san, try to get some rest. Tomorrow's a new day, and you'll need your strength."
"Thank you," I murmured, taking a sip from the glass.
She gave me a sad smile and a small nod, then turned to leave. As the door closed behind her, the soft click of the lock was a small reminder of the safety I once took for granted.
As she walked away, I couldn't help but wonder if she felt any guilt for the part she played in this twisted game or if she was just another pawn like me.
That being said, I was alone now, left to pick up the pieces of my shattered pride and broken spirit. As I sat there, my thoughts swirling like a storm within my mind, I couldn't help but wonder how things had gone so horribly wrong.
This is your fault, Yuki-chan... you monster!
For now, though, all I could do was close my eyes and try to escape the nightmare that had become my reality, if only for a few precious hours.
13.2
Ayanokōji Kiyotaka
After a rather eventful day last night, Yuki, Chiaki, and I enjoyed breakfast in my dorm room, the aroma of freshly brewed coffee and sizzling bacon filling the air. We chatted over what everything the three of us had been up to yesterday, which led to us talking about what I had witnessed between Horikita-senpai and his little sister last night.
"So you're telling me... the reason why Horikita-san is such a bitch is because of the fact Horikita-senpai just can't be honest with her? Geez... what a terrible older brother."
"That's an oversimplification, Yuki," I replied, sighing. "But pretty much. Horikita-senpai wants her not to be like him but is so indirect that Horikita is unable to see the message."
Going back, the message Horikita-senpai wanted to tell his little sister was to stop trying to be like him and to try being her own person— being Horikita Suzune.
But the guy was rather roundabout in his messaging that it ended up unheard by Horikita.
"That's rather sad, though. I mean, we don't have the full picture, but with what Kiyotaka-kun had said, their relationship basically soured because they're both bad at communicating what they want," Chiaki chimed in, the sound of her crunching on her toast punctuating her statement.
"Pretty much," I replied, nodding my head. "That's why as bad as Horikita-senpai handled Horikita, I couldn't exactly paint him as a bad guy since he didn't have bad intentions."
"And I suppose I could be less harsh on Horikita-san then," Yuki added, sighing. "But why are you so invested in making sure she realizes what Horikita-senpai wanted out of her, Kiyotaka? You're not falling for her, are you?"
"Absolutely not," I replied without hesitation. "But with the mission my father had given me, I'm pretty much certain that I'm supposed to try and help talents like Horikita to reach their potential."
Yuki arched an eyebrow at my words, her violet eyes sparkling with curiosity. "Is that so? Well, I suppose I couldn't press you much about it. I'd also prefer it if she'd stop being such a bitch, to be honest."
That's rather mature coming out of Yuki, considering how vocal she was about disliking Horikita.
"Would you no longer dislike her if she'd be more bearable?" I asked, turning my head to the blonde-haired girl, her locks shimmering in the morning sunlight streaming through the window.
"Hmm," Yuki had a contemplative look on her face. "Depends if she ends up falling in love with you, which I'm sure would only be a matter of time. So nope, I still won't like her, but I'll be able to tolerate her."
"That said, there's nothing wrong if Horikita-san does fall for you, Kiyotaka. In fact, I'd call her blind and stupid if she's not harboring any feelings for you," Yuki continued. "Because you're simply the best, and you're helping her grow. Still, I wouldn't be friendly with her, especially if she tries to pursue you."
"You're... surprisingly calm about it. Who are you, and what have you done to Yandere Yuki-chan?" Chiaki jokingly asked, pointing her index finger at Yuki, her cheeks flushed from the heat of the conversation.
"Kiyotaka had said multiple times that Horikita-san doesn't have a chance with him," Yuki replied, her shoulders rising in a dismissive shrug. "If I can't believe his words, then I don't deserve to be his future wife. And there's no way I'm handing him to you, Chiaki-chan!"
What a ridiculous reason, Yuki.
But if that's the mindset you're taking to be more mature, then I suppose I couldn't complain.
"Ara ara~! Is that so, Yuki-chan?" Chiaki asked, tilting her head and raising an eyebrow, her voice challenging. "You sure didn't seem to mind me kissing Kiyotaka-kun and even sleeping on the same bed as him, you know?"
"I still get better treatment than you, so I don't really care," Yuki replied, her lips curling into a smug smile as she took a sip out of her coffee. "So long as Kiyotaka doesn't forget that I'm number one, you can enjoy the scraps."
Yuki leaned back in her chair, crossing her arms and letting out a self-assured giggle. "Besides, isn't it more cruel to get great treatment only to realize you'll never have him?"
Chiaki, to her credit, simply giggled at Yuki's taunt, her eyes sparkling with amusement.
"With how you dealt with Kushida last night, I'm starting to doubt if I could ever trust you to be my significant other, Yuki," I spoke nonchalantly, idly noting the worry on the girl's face. "As I said, I do not care for Kushida... but you also needed to learn to keep yourself in check."
Yuki's face paled, her eyes widening as I recounted the details of her encounter with Kushida. Her hands fidgeted in her lap, betraying her unease.
"Making her believe she got assaulted by some unknown man?" I asked incredulously. "While I do see why you went that route... I deliberately told you to simply cinch in the point that we would not have her ruin the class, not to traumatize her."
Chiaki told me that when Yuki blindfolded Kushida, they made the beige-haired girl believe that another 'man' had entered the room, who was tasked to have 'his' way all over her body... but in reality, that was just Yuki's doing, one aided by an elaborate hand prop that was as calloused as a man's hand could be.
A part of me did think, however, that Yuki simply wanted to squeeze Kushida's breasts, which was why she did not want to tell me... although that's unlikely.
From what I know of Yuki, she most likely intentionally left out that information just because she wanted to 'prove' herself to me, which was rather short-sighted of her.
Doing that would simply earn her my wariness.
She was lucky that I had come to care for her, or I wouldn't have even bothered berating her.
"You did not even tell me you had that in the cards," I added, my eyes cold and icy. "I need you to be honest with me moving forward, Yuki. Don't pull something like that behind my back ever again."
"Ki-Kiyotaka-kun... aren't you being too harsh?" Chiaki asked in concern, her eyes filled with sympathy for Yuki. "How else would the goal even succeed?"
"The goal was already accomplished once we got the recordings, Chiaki," I replied, sighing. "What happened yesterday was essentially Yuki lashing out at Kushida and turning her into her plaything... as well as an unrelated secondary objective that I had only learned last night."
Yuki did not say a word, not even touching her meal. She remained like that for a good minute before tears fell down her eyes.
"I-I'm sorry, Kiyotaka..." Yuki's voice quivered as she trailed off, her trembling hand wiping the tears from her reddened face. "I... was just caught in the moment, and my anger made it hard for me to stop what I was doing."
I leaned forward slightly, my eyes locked on hers, trying to gauge her sincerity. "Don't get me wrong," I said in an attempt to ease things over. "I do not necessarily condemn what you did. In fact, I could care less about what you were going to do to her. My disappointment, Yuki, was not about what you did with Kushida... but what you had done to me."
My gaze intensified, and I could see Yuki shrink back slightly. "I hate being lied to, Yuki," I continued, my voice steady and firm. "Remember that."
Yuki nodded, her face still tear-streaked, and her lips quivered as she tried to regain her composure. "I understand, Kiyotaka. I'll make sure to be more transparent with you moving forward."
"Good," I said, my tone still firm but softening a bit. "Now, let's focus on the tasks at hand. We need to figure out a more elaborate way of dealing with the problem. Kushida's testimony and the planted pieces of evidence are step two. Let's discuss step one."
Yuki wiped her tears and took a deep breath, her posture straightening and her eyes narrowing as her mind already focused on the task at hand. "I think I have a plan," she said, her voice steadier once again.
"We could use their cell phones to make it look like they had been communicating about the assault beforehand. We just need to make sure we get access to their phones without raising any alarms."
"That's a good idea," I said, nodding in agreement and leaning back in my chair. "But how do we get access to their phones without them noticing?"
"We could distract them," Yuki suggested, her eyes darting around the room as she considered the possibilities. "For example, we could create a commotion outside their dorm room, and while they're busy checking it out, we could sneak in and grab their phones."
I frowned, crossing my arms over my chest. "That's risky," I said, shaking my head. "We need to make sure we have a backup plan in case things go wrong."
"Right," Yuki said, her fingers tapping rhythmically on the table as she nodded. "I have a better idea... although it has more conditions than what I initially presented. We could also try to hack into their phones remotely. I'm not an expert, but... we can find someone capable?" Yuki trailed off, unsure of her plan.
I suppose that's the difference between Yuki and me when it came to scheming.
Unlike Yuki, who's more in tune with intricate but risky plans, I thrive in making schemes that have multiple layers connected and a surprisingly low risk to them.
Fortunately for Yuki, I can fill in the holes in her proposal just fine.
"I can do it. I learned it over the past three years when I was given a computer to work with. I also have access to the contact information of students since my clearance as Vice President allows me to," I replied.
"And then, I pretty much reverse-engineered the messaging system already," I added, taking one last sip out of my coffee.
"Y-You did?!" Yuki's eyes widened in disbelief, her hands clasping together on the table.
Indeed.
As I said, over the past three years, I've spent some time mastering computer programming and hacking as it was part of a special curriculum taught to the 4th Generation of the White Room. Seeing as I was the only student left when the instructors decided to add that in, I was the only one who was taught the more complex ins and outs of the field.
And, of course, my natural aptitude allowed me to grasp these complex subjects rapidly and dive deep into practical applications.
"Those texts you received from Manabu-senpai actually came from me," I replied off-handedly.
I did not fully intend to learn to hack into the school system, but in an attempt to challenge myself, I spent countless hours studying the school's system, cross-checking it with various security systems, and learning ways to minimize my digital footprint when testing out penetrating the system.
While it's almost impossible to be completely undetectable, my skillset allows me to come close.
That said, the bounds of how much I could get away with were rather limited, given the security of the system was tight, just as you'd expect from a government-sponsored, state-of-the-art school.
But that didn't mean I couldn't do anything nifty.
For example, I used my knowledge to send fake messages to Yuki to make her do my paperwork when I didn't feel like doing it.
"So it was you who made me do your paperwork for you!" she exclaimed, her eyes narrowing as she jabbed a finger in my direction. "You're evil, Kiyotaka! And all you did was hang out with Hirata-kun and Sudo-kun. I feel sorry for cursing Horikita-senpai now."
I couldn't help but be amused at her reaction. "I apologize for that, Yuki. But it was all in good fun, and it did help me practice my skills."
"Fine, I'll forgive you this time," Yuki said, pouting. "But you owe me one, okay?"
"You're not exactly in any position to bargain with me, Yuki," I replied, shaking my head. "But thanks for your forgiveness."
"I'm sorry, okay?" Yuki replied in a low tone, her gaze downcast. "I'll make sure that won't happen again. I don't want you to hate me, Kiyotaka."
"Good."
"Getting back to the plan," Chiaki interjected, "how do we make sure that the message exchanges we plant on their phones won't be traced back to us?"
"I can handle that," I said confidently, my fingers interlocked as I leaned back in my chair. "I'll create a virtual private network (VPN) to mask our location and use an encrypted messaging service to send the messages at the exact time that they need to be sent. Even if someone tried to trace it, they wouldn't be able to find us."
"Wow, Kiyotaka-kun, you're really amazing," Chiaki said, her eyes sparkling in admiration.
"I do my best," I replied modestly.
"Alright, let's get to work," Yuki said, determination in her voice as she straightened her back and focused her gaze on me. "We need to make sure this plan is foolproof."
Well, the plan is mostly fool-proof with me at the helm.
First, securing the numbers are easy due to my position in the Student Council, which allows me access to the e-mails and numbers of every student should I need it.
That being said, what happened yesterday between Nagumo-senpai and me when we exchanged numbers was simply out of courtesy, as it is, of course, more polite to get someone's contact information in person.
With that card in our hand, I could easily see the phone numbers of the students we were planning to expel and do what I needed to do.
Since it was just a small-scale manipulation of the system, it was practically inconsequential. The school wouldn't even bother with punishment so long as I remained undetected, which I could easily do.
As for Kushida, she was to attend classes normally, as if nothing had happened last night. However, later in the night, she will be walking in the direction of a certain location in school, just as instructed, one that, from the profiles that Chiaki had gathered, was frequented by the four students.
This is to push forward the realism that they did indeed attempt to attack Kushida.
At about 7:45 PM, Kushida will then file a complaint regarding the four students, narrating everything that was done to her, including some 'pictures' they made her pose in, one that was a product of the four of them 'blackmailing' her into doing something like that, as well as the fake assault.
That being said, with the messages, the physical evidence planted by Chiaki, Chiaki and Yuki's study of the tendencies of the four students, and Kushida's acting abilities, this plan is set to go without a hitch, which accomplishes two goals:
1. Satisfying our collective irritation by expelling men who lusted after Yuki; and
2. To send a warning shot to Nagumo-senpai.
After all, it was time for him to know that the game had just begun.
Now that I thought about it, I suppose Yuki did me a favor by simulating an assault on Kushida, as it would make her acting look even more authentic.
Even if Kushida's testimony were a web of lies, no one would question her simply because she would be reminded of what had happened to her and, thus, would deliver her story akin to an actual victim.
It was human psychology at work.
However, it still did not sit well with me that Yuki left out critical details of the plan that she had concocted. While I did understand why she did that, I was still not happy at the fact that it happened.
Because it reminded me of the first fourteen years of my life.
I will not let anyone treat me like that... ever.
End of Chapter
Closing A/N:
This simply serves to answer the questions about what had happened to Kushida, as well as a set-up for future plans.
I hope that it was as comfortable as uncomfortable could ever get. (A bit of a paradox, but you get what I mean)
Kushida's POV... is meant to reflect how someone would realistically feel after everything that had happened to her. But it is clear here that there's still a small ember in her that's simply biding its time until the flame could return full blast.
Of course, that's not going to do anything, but Kushida will try.
Honestly, I don't even know if I did it well, but since I liked the flow of the words, I simply decided to go along with it. Hahaha look at what too much divergence plotting does to an MF.
As for Chiaki... as some of you might have thought already, her interaction with Kushida was faked and thought out. It's orchestrated by Kiyotaka, as implied in Chapter 12 when he helped them set up what to do with Kushida for the night.
As Kiyotaka said in Chapter 12.5, there needs to be a balance when seeking to control a person, and he had orchestrated a scenario where Kushida would see Yuki as the demoness and Chiaki as some sort of an empathetic accomplice that simply had to do what she had to do.
Now, I also set up a potential progression in the relationship between Yuki and Suzune with the breakfast scene, as well as added information as to what Kiyotaka thought of the event.
We also delved into the plans they've made to expel the four second-year students... and I hope it's something that you guys could realistically buy happening. Personally, I don't think something like this is ever going to work IRL, but Kiyotaka's Kiyotaka, so hopefully, there's still some semblance of believability there.
Lastly, I addressed how Kiyotaka felt after finding out what actually happened with Kushida. It's rather twisted in a way, since Kiyotaka's effortlessly and callously manipulating everyone, but his experiences in the White Room made him develop a heavy dislike... or even hate at being lied to. He believes that what Yuki did to him was a slight to him, and in a way, reminded him of his previous life... which ticked him off.
As I have always said, Kiyotaka is not perfect. He has his moments that are just like what happened here in this chapter. However, there is growth... since he was willing to let it go due to the fact that he cared for Yuki. But he made sure Yuki knew that this was the only time he was going to let it go... just for emphasis.
See you in Chapter 14!
