Chapter 52

Days passed after my duel with Doni. It was a certain day. Kaori and I are typically going to our club as usual. But, suddenly a certain light pink-haired bubbly girl coming to our class to interrupt our plan going to the club. This time she brought deadpanned Kaguya with her.

"Izumi-san! Kaori-san!" Chika waved her hand from the door.

"What do you think it is this time?" Looking at the happily waving Chika, I asked Kaori beside me.

"Saa, but it won't be something important." Kaori shrugged and answered.

"But, I don't think we could ignore her..." I said.

"I know, right...Look at Kaguya-san, she even comes with deadpanned eyes." Kaori said while pointed at Kaguya who was silently looking at Chika.

"Pff... That's actually quite adorable. She still came along even with that expression." I laughingly said.

"Haha, that's true. But probably she just can't reject her because she would definitely use her crying skill." Kaori laughingly answered.

"Well, let's just ask her what is it this time," I suggested. Then Kaori and I approached her and Kaguya.

"Yo, Chika-chan. What is it this time?" I greeted her and asked.

"Good question, Izumi-san! Today, let's go and investigate the four mystery of Shuuchiin Academy!" Chika excitedly said.

"...." I looked at Kaori and Kaguya with a blank look in my face.

"..." Kaguya and Kaori looked back at me with the same expression as me.

"Ah! I forgot I had a promise with my Shishou. Hahaha, this is troubling. Shishou must be waiting for me" I looked at my hand watch and said with a fake surprised expression as if I just remember it.

"That face! It must be a lie! Please come with me, Izumi-san!!" Chika desperately said.

"We also need to go training because there is a new instructor coming, right Kaguya-san?" Kaori said to Kaguya.

"Come to think of it, the previous instructor was absent because of pregnancy." Kaguya nodded affirmatively and added.

"That's also lying! I know your instructor is a 40-year-old v.i.r.g.i.n middle-aged woman! Nee nee, please come with me, Kaguya-san, Kaori-san, Izumi-san!" Chika cryingly shouted. Because of her shout while crying, many students looking at us weirdly.

"..." Kaguya, Kaori, and I looked at each other and sighed resignedly.

"Fine... let's go..." We simultaneously said.

"Yay! Let's go!" Chika enthusiastically said.

Thus our journey to investigate the four mysteries of Shuuchiin Academy is starting. The first place we're going to is class 1-C which is beside Kaguya and Chika's class.

"Speaking of which, why four? Isn't it usually seven?" I curiously asked.

"Eh? I don't know. Maybe because it just recently made?" Chika and wonderingly said.

"Recently made?" Kaguya tilted her head wonderingly.

"Indeed! It seems the mystery existed in our generation." Chika nodded affirmatively and said.

"I don't think that can be called school mystery... Isn't it just rumor?" Kaori said.

"Ignore such trifles matter! It would be fun!" Chika excitedly said.

"Yes yes. Anyway, what is the first mystery?" I asked.

"It was a certain day after school. A girl who forgot something in her class decided to get back to school to take it. Because it was evening, the only students in the school area were just the student councils and club members, and neither of them in the class at that time.

The girl slowly walked in the dark corridor in the middle of cloudy weather. No sounds can be heard inside the school building. The girl knows, a chance she saw a student inside the building at that time was very low. Therefore, she didn't feel it was odd.

But when she almost reaches her class, a giggling sound of a girl can be heard. The girl thought it was just a friend chatting in the classroom. Feeling curious, she peeked from the gap of the door.

In her eyes, reflected a raven-haired girl talking happily to someone. But that 'someone' wasn��t there. The girl becomes frightened thinking the raven-haired girl talking merrily with a ghost. She slowly steps back to not startling the raven-haired girl.

But she slipped and falls down to the floor causing the raven-haired girl alarmed by the sound. The raven-haired girl instantly looks at the girl with a frightening eye and said, 'Go, Tomo-chan!'.

Hearing that, the girl immediately stands up and runs away from the class. Rumor said the raven-haired girl actually existed, and she can communicate with spirit." Chika explained thoughtfully.

"Ooh!! That sounds like a proper mystery!" Kaori excitedly said.

"Well, the story is. We don't know the truth, though." I added.

"If you said it, I'm curious what the mystery actually is," Kaguya said curiously.

"Right? That's why I said it would be fun." Chika joyfully said.

Without realizing we were near the class in the story, Class 1-C. No talking voice can be heard from our place, but to not alarm the girl we mutually decided to walk slowly without talking. Then a girl's voice suddenly can be heard.

Hearing that, we stealthily opened the door for a bit and peeked from the gap. There is indeed a raven-haired girl talking to something that didn't exist.

"Whoaaa, it's true!" Kaori whispered excitedly.

"Can't believe it's actually true..." Kaguya said amazedly.

"Hehe... but what is she talking about I wonder?" Chika tilted her head and wonderingly said.

"She is talking about how she hasn't made friends in this school..." I said piteously.

"I think this mystery was just about a lonely girl who talks with her 'air friend'..." Kaguya said while looking at the girl with pity.

"Uwa... that's so sad..." Kaori said while looking at the girl with pity.

"Let's come inside and be her friend!" Chika suggested.

"Don't!" Instantly I promptly stopped her.

"Why, Izumi-san?" Chika asked.

"Imagine if a group of students suddenly approaches you when you were talking to your nonexistent friend. It would be super embarrassing, you know." I carefully explained.

"Ah!"

"Indeed... Let's not interrupt her for now and go to the next mystery..." Kaguya nodded approvingly and suggested.

"Can't be helped, I will befriend you tomorrow, raven-haired girl!" Chika enthusiastically said.

We stealthily stepped back and promptly went to the next place which is the gymnasium.

"What is the next mystery?" I asked Chika as we walk leisurely.

"Next is, 'For some reason, many boys go to the gymnasium after school every day.'" Chika said after thinking for a bit.

"This is clearly just a rumor... not even a mystery..." Kaguya said resignedly.

"But I'm curious what are they watching." Kaori curiously said.

"Oh look, there is a cheering crowd of boys there..." I pointed at the crowd at the gymnasium entrance and said.

"Uwaa... I don't want to go there..." Kaguya disgustedly said.

"I'm not that disgusted but it's kinda hard coming to that crowd," Kaori instantly added.

"Then, Izumi-san go there for us, please..." Chika earnestly begged.

"*sigh* Fine..." Saying that I casually walk to the crowd. Good thing I am considerably tall, so I can see it even from behind. Because if I casually greet them, they will make a way for me to enter and I don't want that.

In the gymnasium, there is The girl basketball club training. There is a big-b.r.e.a.s.ted blonde girl as a member playing basketball in the club. And every time she runs, every boy in the crowd shouted fiercely.

"OOOOOOOOOOOOO" The crowd shouted joyfully looking at the blonde-haired girl. Or should I say they shouted after looking at the swaying b.o.o.b.s of her as she runs.

'....'

I do think her b.o.o.b.s were quite big. But for me who has seen a fair share of beautiful b.r.e.a.s.ts isn't that excited about it. So, I head back to Kaguya, Kaori, and Chika with deadpanned eyes.

"What are they watching?" Chika asked curiously.

"What is it, Izu?" Kaori also asked.

"It's not something good, is it?" Kaguya looked at my deadpanned expression and asked.

"They're watching swaying b.o.o.b.s of a girl playing basketball..." I said with a blank expression.

"..." Kaguya is looking at the crowd with a disgusted expression while Kaori and Chika awkwardly silent without knowing what they should say.

"Let's just proceed to see the next mystery... I don't think the last two would be good too..." I suggested and said.

"Y-yeah, let's go..." Chika and Kaori awkwardly said.

After that, we went to the third mystery place which is the board chairman room. It seems the mystery was called 'Pegasus and Fairy.' It was about the board chairman who gets abused verbally with his beautiful butler. That's why they called it 'Pegasus and Fairy.'

Because we can't disturb this one too, we decided to go to the last mystery which is the voice in the boy's toilet in the first-year hall. When we reached the boy's toilet, a quite loud shout can be heard from inside.

"WOOOO, I WAS ABLE TO TALK WITH HER TODAY!!!"

"*sigh* I recognize this voice..." I sighed and said.

"I also know this voice too..." Kaori also said deadpanned.

"Why there are many weird people in this school..." Kaguya facepalmed and said.

"Maa maa, but with this, the four mysteries of Shuuchiin Academy has concluded!" Chika delightedly said.

"Well, let's go to McD this time, Kaori, Kaguya," I suggested.

"Yay! I really like the milkshake there..." Kaori excitedly said.

"Very well, I will inform my driver to pick me up later," Kaguya said.

"Wait! Don't ignore me please!!!" Chika frantically said.

'I don't know what happen but, good for you, Miyuki-chan. But please don't shout in boy's toilet after school...'

Later we came to know the raven-haired girl is Mikazuki Yozora. The blonde girl is the daughter of the board chairman, Kashiwazaki Sena who trying various clubs at that time.
