Nanana’s Buried Treasure Volume 3 Chapter 5.4

“TRANSLATOR:Foxsunes/EDITOR TheNix”

  ｢So, what about volleyball now?｣

Nobody could answer Ibara-senpai’s query, to be precise we couldn’t think of an answer. We’ll leave this for now and think about the next number.

  ｢The next number is √1780.4.｣

  ｢It seems unrelated to volleyball. If that’s the case then it’s wise to think that this number itself represents something.｣

I agree with Tensai’s analysis. Ibara-senpai was next to her with her arms crossed thinking about what this number represents. 

  ｢The number inside the root is the number which becomes the number inside the root if i’s squared….so, what’s that number? ｣

I don’t think this is that simple. 

President Yuiga took out his cellphone immediately. 

  ｢Let’s use calculator….It’s 42.19478640…｣

I see, so what’s this number? 

  ｢It’s marathon.｣

Tensai answered my question.

  ｢Tensai’s right. If we round-off this number it turns into 42.195 which is the length of a full marathon which is 42.195 kilometers. ｣

I see, so that’s what the number means. 

  ｢This seems right, so the second hint is marathon. I think we need to go look at the section showcasing marathon shoes.｣

  ｢So, Isshin. You mean that these numbers are pointing at sports sections in this shop?｣

Kagetora-senpai asked and Yuiga senpai nodded. 

  ｢I think so.｣

  ｢If that’s the case then the first hint, volleyball is pointing at the volleyball corner.｣

  ｢If that’s the case then the next number 3776 might be pointing at some sort of sport.｣

What can it be? Basketball, tennis, soccer, baseball….. I wonder what it could be. I thought of games related to 3776 and my mind got filled with different kinds of games. 3776, 3776….. 3776 goals, 3776 shots…..3776 shots?

Everyone stood around thinking about a sport related to the number. 

  ｢Ah, I got it! It’s 3776 meters!｣

D’arc clapped his hands. 

  ｢What is it D’arc? What’s up with 3776 meters?｣

Was there any sport that’s related to such a distance? D’arc was smiling looking at my confused reaction. He answered while smiling. 

  ｢Jyuugo-kun, the answer is Mount Fuji’s altitude.｣

  ｢…..Aaaah, that’s right.｣

A sport related to Mount Fuji… that’s mountain climbing. I was thinking about mainstream sports so I couldn’t think of it. But Nanae Island is a southern Island, are there shoes for mountain climbing here? I looked around wondering about it and I saw a section where outdoor goods such as mountain climbing shoes, bags, and caps were showcased. 

  ｢Good job, D’arc.｣

I praised D’arc and he seemed like he didn’t dislike it either. 

  ｢Volleyball, marathon, mountain climbing. The last number is 2. Is there any sport related to 2?｣

After hearing President Yuiga’s question, each of us answered what came to our mind. 

  ｢Tennis.｣ Tensai answered. 

  ｢It’s table tennis.｣ Saids Tsurezure-senpai. 

  ｢Aren’t all pair sports related to 2?｣

President Yuiga nodded and smiled bitterly at my query. 

  ｢You are right, 2 can be related to any sport and we can make sense out of it in multiple ways. It’s difficult to specify certain game using this number.｣

President Yuiga is right, there are multiple possibilities and we can’t get a single answer from this. Isn’t there any other hint? 

  ｢Tsurezure-dono, can you show me the pamphlet again?｣

Tensai reached out her hand and Tsurezure-senpai gave the pamphlet to her. 

Tensai looked at the pamphlet and nodded. ｢Hm.｣

  ｢I assume the last number isn’t related to sports.｣

  ｢Why do you think so, Tensai?｣

  ｢The answer is the floor vending machine was on.｣

I looked at the pamflet. 

  ｢First two vending machines were on the third floor. The number they showed was 2316. Next were seven vending machines on the first floor. They formed three numbers when the building numbers were taken into consideration.The numbers were 6, √1780 and 3776. The last number was 2 and it was on the second floor. ｣

  ｢I see, so it wasn’t just forming the numbers according to the floor and building number. The meaning of the numbers were meant to  change with the floor number. ｣

First number 2316 was the location of the shop. Next 6,√1780 and 3776 were for sports sections. And the last number 2 is showing something else. 

  ｢If we go by that then can it be that 2 is related to three sports that we found out about?｣

  ｢Everyone, I think I found the answer.｣

We looked up and saw D’arc waving a little ways away from us. That was the center of three sports sections. 

  ｢So, the last number was a room number.｣

What D’arc found was a changing room between three sports sections. There were five changing rooms arranged in c shape. We looked inside room number two but found nothing but walls and a mirror, it didn’t have anything interesting inside. All we could see was our confused faces staring at us from inside the mirror. 

  ｢This must be some sort of mistake.｣

I get what Ibara-senpai is saying, there really is nothing here, it’s just a normal changing room. But I felt something weird, something isn’t right. I wondered what it could be as I stared at the mirror. I noticed something weird. 

  ｢Hey D’arc, isn’t this mirror weird?｣

  ｢?Hm, what’s weird about it?｣

  ｢Isn’t it dark?｣

  ｢Ummm, it feels like it but isn’t it because of the lighting? See, the light doesn’t illuminate this room properly.｣

I looked up, he’s right about that. Due to the positioning of the lights, this room is dark. 

  ｢But….that’s kinda weird.｣

  ｢What’s weird about it, D’arc?｣

  ｢It’s weird that it’s dark even though it’s the changing room. Shop wants people to buy clothes, so they are extra careful about the lighting in changing rooms. They make sure that it’s lit up well so that clothes look better. For example, the shop I work in has bright lights set for changing rooms.｣

It makes sense. 

  ｢Both of you are right.｣

Said President Yuiga. 

  ｢The rest of the changing rooms have lights set above them but this changing room at the end doesn’t have any lights set on the ceiling due to its architecture. And it’s as Yama-kun said, the mirror here looks dull compared to other mirrors in rest of the changing rooms.｣

After it was pointed out by President Yuiga we all went to other rooms and compared the mirrors to the mirror in room number two. The mirror in room number two looked slightly dull compared to the rest. It isn’t because it’s dirty so I wonder why it’s like this. 

I went inside the room without thinking much and touched the mirror.

  ｢Hm?｣

I proceeded to knock and I found out the reason behind it being dull. 

  ｢This mirror..  it’s metal.｣

  ｢What do you mean it’s metal, Yama-kun?｣

  ｢It’s as I said. It isn’t a mirror made out of glass. It’s a metal with a smooth surface, it looks like a mirror because it’s reflecting light.｣

President Yuiga nodded at my report. 

  ｢I see.｣

  ｢So, it’s a metallic mirror.｣

  ｢What’s a metallic mirror, Isshin-sama?｣

  ｢Nowadays, glass mirrors are common but before we had the technology to produce glass mirrors surface of metals were polished carefully and used as mirrors instead.｣

  ｢Yeah, we did learn something like that in history lesson. It was something called a bronze mirror.｣

  ｢Yeah, you are right Kagetora.｣

  ｢So what if this is a metallic mirror?｣

  ｢Considering what we have been through, we already have the answer. Ibara-dono?｣

  ｢What is it shorty? Don’t be so pompous and tell me the answer already.｣

  ｢He.. hey. Don’t rub my head so violently, Ibara-dono! My hair is going to be messy!｣

  ｢Ibara-senpai, it’s magnetic memory alloy.｣

Ibara-senpai was hugging Tensai from behind and being mean to her so I answered on Tensai’s behalf since she wasn’t in a situation to answer. 

  ｢Ah, so it’s the metal from the vending machine.｣ Ibara-senpai nodded. 

  ｢I assume that a keyhole would form if we bring a specific electromagnetic wave near this.｣

  ｢Eh? So you mean this metallic mirror is the gate to the ruin?｣

  ｢I think so, yeah.｣

But who would have thought that the entrance of the ruin would be a metallic mirror in a changing room in a sports product shop. This is the reason why the ruins in this Island are hard to find. They are all in places that no one would imagine. 

  ｢Yama, so how are we going to get a key that emits electromagnetic waves? I don’t really get what electromagnetic waves are.｣

Yeah, that’s what people are going to think next. 

  ｢President Yuiga, what do you think about this situation?｣

  ｢It’s same as what you are thinking, I think we can open this up with the same key used to open up the vending machines.｣

Seems like he knew what I was thinking. 

  ｢Isshin-sama, does this mean that the part timer from before has the key to open this up? But I don’t think things are going to go that…..｣

  ｢It is how the ruins on this Island work, the key to get to the ruin is always there near the ruin and that’s something that I can say for certain. It would be pretty reasonable to think that way considering how we reached them before this metallic mirror.｣

  ｢I see, so that’s how the hints leading to ruin work.｣

  ｢But it’s not going to be that simple, there should be more to it than the key Yokota-kun has. I assume that we need to get all the keys given out to people who are refilling the black vending machines so, this metallic mirror needs multiple keys.｣
