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 3. Chapter 4.5 - Building the Foundation
Ayanokōji Kiyotaka
The sun was at its highest point when Yuki and the others returned, beads of sweat trickling down their faces. They had a glint of victory in their eyes as they informed us of a favorable area by the riverside. Ten minutes of trudging through unexplored terrain and we arrived at the area they'd discovered. Just as they promised, the site was a balanced blend of grassy terrain and canopy trees that cast a cool shade, the river humming its melodious tune nearby—the ideal place to set base.
I made a quick appraisal of the area and wasted no time instructing Yōsuke, Ken, Akito, and Ike to begin setting up camp. Alongside a few other boys from the class, they began to work.
As our base started to take form, Chabashira-sensei emerged from the crowd, her hawk-like eyes scanning the scene. Her shoes kicked up a trail of dust, and her long hair was swept around by the soft, warm breeze. Eventually, her gaze found me.
"Are you choosing this place as your base camp?" She questioned, her voice retaining the authoritative tone she always carried, even amidst the wilderness.
"Yes, Sensei," I responded, meeting her gaze squarely and giving a slight nod.
"Alright then," she nodded, seemingly satisfied with my choice. "We'll be having our roll call here at exactly 8 PM. Make sure everyone makes it on time."
"We understand, Sensei."
Not long after, the boys had finished setting up the two tents. The girls also helped out in sorting our things, ensuring everything was orderly. With that preliminary task done, I called for everyone's attention once more. Yōsuke and Yuki then gathered our classmates, and soon, the class gathered before me.
"Good job thus far, everyone, especially Ike, Yōsuke, Ken, Akito, Yamauchi, Yuki, and Kushida, for scouting for the riverside as well as our base," I began by applauding the people who did the heaviest work so far. "Now that we've pretty much settled here, I would like to realign everyone pertaining to what we're going to do here and on how we'll spend our points."
At my words, a ripple of reactions passed through the crowd. Some classmates pursed their lips, their eyebrows furrowing slightly at the prospect of being made to work. It was evident that their discomfort was a byproduct of their lack of experience in the outdoors. It made sense, but it was something that could be worked around.
"Don't worry too much about it. I know some of the class aren't used to this yet, so feel free to tell me if you disagree with anything or feel uncomfortable. I'll do my best to compromise with your needs.
Shinohara raised her hand. "Uhh... Ayanokōji-kun, what will you do about the toilet?" She asked.
"The toilet? Don't worry about that. According to the manual, we can install portable toilets. They'll cost 20 points each," I answered.
Upon my assurance, the girls heaved out a sigh of relief.
"Hold on, Ayanokōji," Yamauchi interrupted, drawing the attention away from the now visibly relieved girls. His brow was creased with skepticism. "Wouldn't spending 20 points for a toilet be too much? And that goes for other expenses too. Think about it this way... we could probably sustain ourselves with the fruits, vegetables, or the like that we could find around here. And since we're in the river, water isn't that much of a problem, too."
Plenty of boys agreed with his opinion. To be honest, I was impressed with his logical idea, considering the image I had of Yamauchi. On the other hand, the girls began to panic, no doubt worried about the possibility of me being swayed by Yamauchi's proposal. Some of them shot me anxious looks, silently pleading for me to stand by them.
Azuma and Nishimura, meanwhile, locked into a debate with Yukimura, who had just voiced his agreement with Yamauchi's proposal.
"I don't understand why we're going to limit ourselves when we're living on a deserted island of all places. In case you haven't picked it up from sensei earlier, the point of this test isn't to hold out and try to save 300 points. It's on using our points effectively. We're not saying we should spend all our points, but some spending is necessary," Azuma argued, sighing.
Azuma Sana was one of the more intelligent students in the class, having the tenth-highest score on the mock test last April as well as the finals. However, despite being cute and smart, she remained somewhat overlooked by the boys due to her no-nonsense personality. Her straightforward manner was reminiscent of Horikita, but unlike Horikita, Sana had a more sociable demeanor.
"I agree with Sana-chan. I'm sorry, Yukimura-kun, but if you think 40 people could live here on the bare minimum, I would say you're incredibly out of touch, considering a lot of us here don't have much outdoor experience," Nishimura added.
Yukimura looked taken aback by the sound arguments presented by the girls, but he held his ground. "I get that, but won't we get ahead if we restrain ourselves as much as we can? We're only trailing Class A by 14 points, or maybe it's 25 now, due to the finals. But the point is, the more points we save, the higher the chance that we'll surpass them."
"And we can still do that eventually," Azuma shot back. "The point is, everyone's comfort should be a priority. If our classmates' health starts to deteriorate, what's the point of holding out?"
Yōsuke, who had been listening for a while, decided to insert himself into the conversation. "Not just comfort, Yukimura-kun, but everyone's mental state needs to be taken into account as well. We've seen earlier how uncomfortable the girls were with the toilet from earlier. There's no telling what would happen if they become increasingly anxious. I fully support Kiyotaka's decision to buy a portable toilet."
With that settled, I clapped my hands to take everyone's attention.
"There are some merits to Yukimura and Yamauchi's points, but I will be purchasing the portable toilet," I announced, standing firm with my decision.
As I made the announcement, a wave of relief swept through the girls, their faces lighting up with gratitude and approval. The boys who had supported Yamauchi and Yukimura's proposal, including Yamauchi and Yukimura themselves, grimaced but didn't protest further.
"That being said, do you guys remember what Mashima-sensei and Chabashira-sensei said earlier about the exam?" I asked, my eyes drifting over the class.
"The theme is freedom. And while this might be a great way for us to surpass Class A, I honestly would want us to take it easy and treat this test as an actual vacation," I continued.
"A vacation?!"
"Wait, isn't that too irresponsible?"
"Ayanokōji, are you sure about this?"
A lot of the class, mainly the boys, voiced out their concerns about what I had shared. After all, announcing that I was planning to have the class treat the exam like a vacation wasn't something they'd expect to hear from me.
In fact, from what I did earlier in the planning and mapping out our route, they would assume that I was going to take the exams head-on. I could see their minds churning, trying to reconcile this unexpected revelation with their earlier assumptions.
But while their concerns had merit, they were missing a certain detail in the puzzle.
"I am serious about it," I said, doubling down on my words earlier. "Besides, it's not like our results are limited to how many points we have left over. There are several spots that we could occupy in the east, and within the week, we should be able to get a decent amount of points from spots alone."
"Wouldn't that be risky then, Ayanokōji? The more spots we occupy, we risk the chance of having our leader exposed. If the other classes would stumble upon us marking a base and guess our leader correctly, our points from occupying the spots would be null," Yukimura questioned, his brows furrowed in thought.
It was a reasonable conclusion to make based on the rules presented in the manual.
"That's true, but even if that were to be the case, don't worry about it. I've already thought of a way out of it," I explained, looking him directly in the eye.
While my explanation was quite vague, Yukimura backed down. It was most likely a byproduct of his trust in my abilities, having proven myself to the class right from the beginning.
"With that out of the way, we'll set a goal. I want us to have at least 100 points remaining by the end of the exam," I declared.
"A vacation is fine... but that's 200 points!"
"Yeah... that's a bit too much!"
I nodded my head. "I can see where you guys are coming from, but it'll be fine. It's not like we'll just be lounging around, we'll be trying to occupy spots too. I've done the numbers already, and I think we'll still get good results even if we'll be conservative in procuring spots."
"What do you mean by that, Ayanokōji-kun?" Nishimura asked. While Nishimura was supportive of my idea of maximizing comfort, she was probably shocked that I wanted to spend that many points.
Turning to her, I responded. "If we were taking a conservative approach in occupying spots, we'd still be able to get around 30-35 points from securing two spots. That still puts us at 130-135 points. Now, if we were to go further and get more spots, we'd probably end up with around 180 points. I'd say those are pretty good numbers, and in theory, we'd still be able to make the most out of this test."
The murmurs resumed amongst the class, but no one openly challenged my plan. They were all caught up in processing the numbers and evaluating the possibilities.
"That said, I'm not saying we'll be careless in how we'll spend points. I'm saying we'll have to be more lenient in spending it to maximize our experience," I continued. "We have to address certain things to ensure we'd be comfortable throughout the test. For example, we only have two tents. There's no way that would be enough for all of us. It's good enough for just eight people, after all. And for leisure, we could buy a couple of beach balls so we could play around. We could even have a barbeque grill too. Those things that I've mentioned only cost 72 points—92 if we add in the toilet."
Yuki, who had been silent throughout the discussion, finally made herself known. "I agree with Kiyotaka! Look at it this way, guys. We've been restraining ourselves for too long because the school gets pretty harsh with its rules," she began.
"Besides, it's not like he's telling us to spend all of our points on useless things, you know? He just wants to make the experience enjoyable for everyone," she continued.
Yuki then turned her head to Kushida, who took center stage moments later. Her energy was infectious, and as she began speaking, the class started to lean in. Such was the charisma Kushida Kikyō commanded.
"I also agree! Don't you guys think it would be fun if we made more memories for the entire week? While this is an exam, that doesn't mean we can't have fun, you know? We could be having a barbecue party!" Kushida added, her voice rising in excitement towards the end.
"Well, if we're gonna have a barbeque party, I want Kiyotaka to be the one grilling!" Ken exclaimed, a wide grin stretching across his face.
This idiot...
"Wait, is Ayanokōji a great cook?" Yamauchi asked Ken.
Ken nodded his head enthusiastically. "The best. Kiyotaka cooked for us after the midterms, and that was really the best pasta I've ever tasted."
"How does that relate to grilling, though?" Yamauchi pressed, confusion lacing his words.
"It just does! Besides, he said before he liked cooking pork."
Yamauchi then turned his head to me. "I'll be looking forward to it, Ayanokōji!" He exclaimed, his face lighting up in anticipation.
While it wasn't his intention, Ken had effectively shifted the mood from the class worrying about potential expenditure to discussing having a barbecue party.
After the cacophony of voices had simmered down to an attentive hush, I began to explain in detail the items I planned to purchase with our allocated points—a toilet, four extra tents, a barbecue grill, a set of kitchen tools, a cooking pot, three fishing rods, a handful of beach balls, two lanterns, two parasols for much-needed shade, a hammock, and four walkie-talkies to ensure we maintained open lines of communication within our group.
The tally came up to 145 points, a number that left us with 55 points as a buffer to meet any unforeseen needs or to purchase any other items that might prove to be necessary later. For example, I was debating on whether we'd buy a shower room for 20 points or a water shower for 15 points.
While the obvious choice would be going for the latter, the manual only had reference images for each item and none of the item's descriptions. If the water shower ended up being a bust purchase, the class wouldn't take it well, so I needed to run it through everyone first.
"And that's pretty much it. We'll only be spending 145 points for now since I still need to consult with you guys about whether we should go for a water shower or install a temporary shower," I concluded.
As I broke down my proposed spending plan, I could see understanding dawn on many faces in the class.
"That's... That's a lot better than I thought it'd be," Yukimura muttered, voicing the relief some of our classmates seemed to share.
Apparently, they had assumed that I was planning on spending 200 points right away.
"What does a water shower do, though? How is it different from installing a normal shower? There has to be a reason why it costs less, right?" Karuizawa asked.
"It's probably a shower that's reliant on a manual refill of a water source," Yuki suggested. "I'm not sure, but that has to be the difference, right?"
"If that's the case... we should go for the water shower, then. We got plenty of water around," Ike replied.
"Wouldn't that mean the water would always be cold, though?" Chiaki asked.
Sato groaned. "Why couldn't the school just put some descriptions in the manual? It'd be easier, you know?"
Murmurs began to spread across the class, weighing in the options.
"Enough about that since it's not an immediate need. We'll be continuing our discussion about the shower in the following days or if we get some information. For now, the river should suffice as a temporary bathing area. Of course, we have to consider the bathing schedules for the boys and the girls, but we'll talk about that later," I said.
"Now, is there anything you guys want clarified? Is the budgeting good enough for everyone?" I paused for a bit and waited for anyone in the class to voice out their concerns.
Since no one interjected, I spoke once again. "I'm assuming then that everyone is in approval of the plan. Is that right?"
After a round of nods from the class, I was satisfied and dismissed them for the time being, allowing them to lounge near the tents or whatever it was that they wanted to do. It would seem that with everything laid out, the class' initial apprehension had turned into acceptance and, by extension, confidence in the plan.
"Man... I don't think we'd even need to buy other stuff for the rest of this test with what Ayanokōji had in mind," Ike voiced out, breaking the silence. His comment was met with nods of agreement, setting the stage for a lighter mood.
"We still have 55 points left to spend! Maybe we could convince him to buy two jetskis? They're just 20 points!" Yamauchi suggested enthusiastically.
"Eh?! Didn't you say earlier that we need to be mindful of our spending, Haruki?" Ike questioned, his eyebrows raised in disbelief.
Looking a little sheepish, Yamauchi rubbed the back of his head. "My bad, Kanji! I just got carried away!"
"It's weird how a jetski costs as much as a portable toilet, though..." Miyamoto mused.
I had to agree with Miyamoto. In fact, when I checked all the items available for purchase, I noticed a theme. The essentials for comfort, such as the toilet, shower, kitchen tools, and such, were priced quite steeply, whereas recreational items like parasols, beach balls, cameras, drinks, and even something extravagant like a jetski, were relatively inexpensive.
It would seem that the school did intend for us to enjoy our vacation, but at the same time, attempted to make things challenging with the financial constraints imposed on basic necessities.
After reporting our purchases to Chabashira-sensei, which also included a collection of blue vinyl bags, I sought solace in the comforting shade of a distant tree. My gaze wandered off, lost in the rhythmic murmur of the river nearby.
"Glad to know you weren't planning to play this game like an island survivor, Ayanokōji-boy!"
The familiar voice drew my attention. Turning, I saw Kōenji sauntering toward me, a wide grin on his face.
"Kōenji," I said, nodding my head at him.
"Staying on an island... brings back memories, doesn't it?" He asked, leaning his back against the tree's trunk.
"It does. Both good and bad ones," I replied.
"Ha Ha Ha! To think you believed me when I said those holly berries were edible," Kōenji chuckled as he forced me to remember our first camping trip where he used his superior knowledge about the wilderness to basically get back at me for all the times I had defeated him.
While eating those holly berries didn't make me nauseous, it gave me a bad case of diarrhea, which was annoying to deal with.
"That also led to you being unconscious for three hours when I recovered, in case you forgot," I shot back, making sure he didn't forget his own moment of weakness. His carefree response was just as I expected, brushing off my comment with a dismissive wave.
"I was simply sleeping as I enjoyed the comfort of nature!" he declared with exaggerated grandeur.
"Whatever you say, Kōenji..." I replied, sighing in exasperation.
"Anyway, those barbecues that you'll be grilling for later," Kōenji then pushed off the tree, standing tall once again. "Make sure they're worthy of my palate."
"I'll make sure to coat the ones you'll eat with poison. No worries."
"Ha Ha Ha! Well, I'll be going now, Ayanokōji-boy. Nature calls for me!" And with a wave, he walked away, leaving me alone under the tree's shade once again.
Island Exam Day 1 (1:00 PM)
As the clock struck 1 PM, a parade of uniformed staff marched into our camp carrying the various items we had requested, except for the barbecue grill that I held off from ordering for the time being. Apparently, the barbecue grill came with a set of skewered pork, and upon that knowledge, I told Chabashira-sensei earlier that we'll have it delivered at 5 PM instead.
That aside, the scene before us could have been mistaken for a military operation as seven people efficiently unloaded the cargo, a sense of purpose in their every move.
Once everything was unloaded, four of the uniformed staff proceeded to install the toilet. It was installed some distance away from our tents upon the request of the girls, who wanted some privacy.
I turned my eyes away from the working men and turned my eyes to the other stuff we had ordered— four tents, kitchen tools (which were just a bunch of utensils and cooking equipment), a cooking pot, three fishing rods with baits, four beach balls, two lanterns, a tarp, two unassembled parasols, a hammock, and four walkie-talkie boxes.
And... about 600 blue vinyl bags. It was a lot, but they'll be useful. And since the school told us we could have an unlimited supply of it, then it would be a great idea to take advantage of it.
"Alright. Now that our stuff is here, it's time to work again," I began, clapping my hands to get everyone's attention.
"Firstly, I want the boys to set up the tents as well as the parasols. We'll have three tents on each side, one for the girls and the other for the boys. For the parasols, I want Yuki to take command of arranging where they'll be placed," I instructed.
From the corner of my eye, I noticed Yōsuke walking over to Akito, Ken, Miyamoto, and Makida, pointing towards the tents that were placed on the ground. Great initiative, Yōsuke.
"Next up, the fishing rods. Before I continue, is there anyone here who knows how to fish?" I asked, my gaze sweeping over the group.
Ike raised his hand, grinning. "I know how to fish. Leave it to me, Ayanokōji! I'll teach the guys who'll be assigned with me," he said before following Yōsuke and the other boys who had taken the four tents.
He seemed really eager to prove himself. Perhaps, the positive affirmations Yuki and Kushida gave him earlier boosted his confidence again.
"Great. We'll be counting on you, Ike. Next, I want to assemble a search party who'll find edible fruits in the forest or vegetables, if there are any."
"We'll do it, Ayanokōji-kun!" Kushida offered, her hand shooting up before she even finished speaking. Her enthusiastic volunteering was followed by some of the other girls who were part of her friend group.
"Alright, but I want some guys to tag along with you too. Akito, Ken, can you join them later?" I asked the two boys, who were now unrolling the second of the four new tents
"Yeah, sure!"
"We'll make Ken eat the poisoned ones!"
"Hey!"
"Kenchin and Miyacchi are going?" Haruka asked before she jumped in enthusiasm. "Hey, Kiyopon, can Ai-chan and I tag along with them? Please?"
Haruka and Airi probably wanted to work with people they were comfortable with. Well... Airi wasn't exactly comfortable with Kushida, but the presence of Haruka and the others was probably a sufficient buffer.
I nodded my head at the blue-haired girl. "Sure."
With that set, the girls of the newly-formed search party—Airi, Azuma, Haruka, Ichihashi, and Kushida— gathered and exchanged pleasantries.
Akito and Ken, meanwhile, were still working on the tents under Ike's command, now unloading the third tent. They were joined by Makida and Miyamoto, who were now assembling one of the tents.
"Before I continue with my final point, do you guys have any questions?"
Yōsuke raised his hand. "Kiyotaka, what will we do about drinking water?"
"Great question, Yōsuke." I nodded in acknowledgment, glad that someone had brought up this vital matter.
"I have my eye on having the river be our supply, but we have to be careful about it since we don't know if it's safe or not. And besides, it's safe to assume that some of our classmates wouldn't be comfortable drinking straight from the river, right?" I paused, scanning the faces of our classmates to gauge their reactions.
"Straight from the river? Count me out!"
"Yeah... I don't think we can drink from that..."
"Won't we get sick from it?"
The concerns came thick and fast, mostly from the girls, and I couldn't fault them for their wariness. After all, we still weren't certain if this was actually spring water.
Ike then turned his head in our direction. "I think it's fine. The water is clear, and you can even see from the bottom. From what I've learned from camping, it's probably spring water," he said, his gaze now focusing on the river.
But that wasn't enough to placate the girls, as they still seemed unsure despite his assurance.
"You're probably right, but we'll still check just to be sure. I'll be assigning Chiaki, Horikita, Wang, and Mori to check out the water source of this river. If it's spring, then we'll consider drinking from it. Of course, if you guys aren't comfortable drinking straight from the river, we could boil it for five minutes to eliminate possible bacteria," I stated, noting the flicker of relief in several faces.
"Hmm... from what my dad told me, it usually takes just one to three minutes, but five should be fine if you want to make sure," Ike interjected. "Spring water really is fine as it is, though."
It was, but considering the fact that the group needed to be cohesive, the concerns of many had to be addressed before they would snowball into something ugly— that was one of the things that had been taught to me.
"Girls, is it alright for the four of you to go right now?" I asked, now turning my attention to the Chiaki, Horikita, Mori, and Wang.
"Sure thing, Kiyotaka-kun!"
"Yup~!"
Wang and Horikita both opted to just nod at me.
The four girls quickly fell into a group, ready to check the river. As they moved past me, I reached out to Horikita, my hand gently pulling her back by her forearm. Our eyes met, and I whispered, "Are you sure you're alright? I know I said that I'll give you something to do, but if you're not feeling well, you don't have to force yourself."
She shot me a firm look, her jaw set stubbornly. "I can do this much. I'll go because I want to help the class. I appreciate your concern, Ayanokōji-kun," she replied, her voice steady.
"I'll be there to help her out, don't worry too much, Kiyotaka-kun!" Chiaki called out from a distance.
I wasn't particularly worried, but it would be bad if Horikita suddenly collapsed due to the heat of the sun. The afternoon sun was starting its assault, after all.
"Finally, I want some of the boys and girls to take these vinyl bags and just stack them over your tents. Since I took 600, 300 of them will be going to the boys, the rest to the girls. Since we have three tents per gender, I want each tent to have 100 of them that would be utilized as mats," I instructed.
While there was the alternative route of cutting through them and turning them into makeshift mats, it would be a hassle to clean them up. Besides, with how the bags look, stacking them with each other would most probably give a decent cushion that would be comfortable to sleep in.
Soon after, the rest of the class, especially those who hadn't helped, began to move, taking the initiative to do something. They were probably pressured by the sight of seeing plenty of our classmates working while they simply lounged around.
Everyone except Kōenji that is.
The blonde-haired boy simply relaxed on top of a tree branch, uncaring of what was happening around him.
A few minutes later, all the tents had been set up, and with that, our classmates began distributing the vinyl bags.
Yuki, who had just overseen the setup of the parasols, immediately headed to the tents and directed traffic.
"It's amazing how quickly we've settled into our base. You sure are something, Kiyotaka," Yōsuke mused as he approached me, a sheen of sweat visible on his brow. "Thank you for leading our class."
"I was simply barking out orders. If anything, Ike, Yuki, and you deserve most of the credit, Yōsuke. You guys were the ones mostly on the move," I replied.
Yōsuke chuckled. "That may be, but I doubt I could immediately come up with a plan on how to settle ourselves. You even came up with a figure on how much we're going to spend throughout this exam."
"Yeah! You were super amazing, Ayanokōji-kun!" Karuizawa interjected, appearing just behind Yōsuke.
"Weren't you supposed to help the others in setting up the vinyl bags, Karuizawa?" I asked, arching an eyebrow at her. I noticed her hands were empty, contrasting starkly with the other students carrying and setting up materials.
She shot me an exasperated look, puffing her cheeks out in a pout. "Ah mou~! Can't I just take a little break?" she replied, crossing her arms defensively.
"I was joking."
"Change your voice, then! I couldn't tell with you sometimes. Honestly... how the hell does a guy like you have a great singing voice and have such a dead speaking voice from time to time?" She grumbled.
"I'm with Kei on this one," Yōsuke chimed in, chuckling. "You didn't even sound as deadpan earlier when you were speaking to the class."
"Which should have made it obvious I was joking," I quipped. "That's on Karuizawa for failing to pick up on it."
"Hey!" Karuizawa protested, her arms crossed in faux indignation, but I noticed the smile playing at the corner of her lips.
With Yōsuke and Karuizawa's voices blending in with the soft hum of the air, I took a moment to take stock of our progress.
The class had come together well, forming a small settlement amidst the vast expanse of the wilderness. The sound of the river added a soothing backdrop, and the sunlight scattered through the leaves created a gentle mosaic of light and shadow around us.
Everything sure was coming along nicely.
End of Chapter
Clarifications:
In canon Vol 3, Honami's purchase of Hammocks, cookware, a tent, a lantern, a temporary toilet, a fishing rod, and a water shower, in addition to the food they've purchased, apparently cost them 70 points.
The only figures we know are the cost of the tent (10 points), the water shower (5 points less than the 20-point shower Class D bought, so 15), the toilet (20 points), the fishing rod (1 point if with bait/2 points if with lures), food and water set (1 set = 10 points)
This gives us 13/14 points to work with to determine how much the hammock, lantern, and cookware cost.
While the anime said the cookware cost 20 points, it would be improbable considering what Honami had revealed in the source.
And so, I decided to assume that their basic cookware costs 10 points, the fishing rod 1 point (since it's unlikely they'll go for one with a lure. There are apparently Class B students with camping skills), and the lantern costs 2 points.
Class B's Initial Expenditure (Ayanokōji):
Toilet - 20 Points
Tent (x4) - 40 Points
BBQ Grill (with provisions of Pork BBQ) - 40 Points (To be delivered at 5 PM)
Kitchen Tools (Utensils and other cooking tools) - 10 Points
Cooking Pot - 5 Points
Fishing Rod with bait (x3) - 3 points
Beach Balls - 2 points
Lantern (x2) - 4 points
Parasols (x2) - 10 points
Hammock (x3) - 6 points
Walkie-Talkie - 5 points
Total: 145 points
