This is the second chapter of A World Unknown! I was glad to see how many people seemed to enjoy the first chapter so here's the second one. I'm not sure if this will be a regular, since I have yet to fully finish Arc-V and other stories may come first. But either way, I hope everyone likes this chapter!

Yugo - 16

Yuya - 16

Yuya's POV

We all started heading to our allocated lessons. Yuri was teasing Yugo and Yuto was mainly talking to me unless things got really out of hand. Eventually he just gave in and let the two argue to their hearts content. I soon stopped and gestured to a certain door before I smiled. Yuto had already picked up on why I did that and took Yugo's arm with his hand and dragged him, much to the bluenette's dismay.

Now, I was left alone with Yuri. We walked side-by-side, exchanging information and small talk before we arrived at our lesson. I honestly couldn't really understand why everything was so awkward between us though. I was starting to think I did something wrong before I was snapped back into reality by the teacher calling my name and requesting me to answer the question on the board. I looked at it and raised my brow, it was basically a bunch of nonsensical blabber to me. What is the ratio measures of the in-radius, circum-radius and one of the ex-radius of an equilateral triangle? How am I meant to know that kind of stuff? I gently shrugged and looked at Yuri, since I was allowed to ask someone for help. Yuri flashed me a smile and then started talking in a literal other language of mathematics and geometry.

"The radius is 1 : 2 : 3." Was all I really understood before he went onto things like square-roots and letters equalling numbers and a bunch of other things I couldn't wrap my head around. The teacher was baffled and applauded him on his smarts before she shot me a look as if to say 'work on your studying'. I just smiled sheepishly. My attention went back to Yuri though. "If you want help with Geometry, feel free to come to me whenever. I'll probably be in the library or at our place."

I nodded and thanked him before the lesson continued to progress. Yuri managed to answer all of the questions perfectly and he gladly helped me out with classwork and our book-work. I was glad that I had him beside me in lesson. When the bell rang, Yuri and I headed over to meet Yuto and Yugo. When we finally found them underneath a tree, Yugo seemed drained and Yuto was just calming him down and rubbing his back as the bluenette seemed overwhelmed. I raised a brow and was about to speak when Yuri took the words right out of my mouth.

"What's up with him?"

"He was bombarded with questions. A few examples would be the production of radiocarbon and what causes it, the absorption of ink blotting of paper and what it involves and a few other questions." Yuto replied calmly, Yugo (who was led on his lap now) just let out a groan and mumbled something under his breath around the lines of "English please?"

I barely understood half of the things Yuto were saying, but Yuri nodded calmly and flashed a smile at me after explaining the two questions and what they meant. I managed to understand before Yugo just started complaining about how his head hurt and how he wanted to just go home already. I chuckled and soon Yuri and Yuto joined in before Yuri started teasing the younger male about his behaviour and how he was acting like such a child. Yuto's gaze went from the two now fighting boys to me, which resulted in me smiling when he gestured for me to sit down beside him. We soon started talking about a few things, like where the boys were from and why they came to the school before Yuri seemed to act different. Some of his words unsettled me.

"What's a Tengu(1) doing here?"

Yuto seemed to go rigid when he heard the word Tengu come from Yuri's lips. He bit his lip and looked at Yugo, who also had become tense. I was rather confused but Yuto quickly apologised to me and the last thing I saw was Yuto turn on his heel after I felt a sharp impact on the back of my neck and I barely heard some words come from his lips before I fainted.

"We can't risk you getting hurt, Yuya... Gomen."

Yuto's POV

After Yuri landed the blow successfully on Yuya's neck, we set off to find the Tengu. Tengus were usually supposed to be in mountains regions, so why were there a few down here in flat land? It was rather confusing until I gently pulled up my sleeve and clicked my bracelet off to reveal a kanji symbol, "刃"on my carpus(2) which read "Ha". I looked at the other boys who nodded and did the same. Yugo pulled up his jacket's sleeve and revealed his kanji symbol, "弓" on the dorsum(3) of his hand which read "Yumi". Yuri slid his sleeve up and revealed the kanji symbol, "銃" on his forearm, it was read "Jū". We all said the romanization of our symbols and outstretched one of our hands before we clasped our fists as if holding something.

First object to form was mine. I had a shikomizue(4) hilt tightly in my hand. I removed the sheath and spun the blade around to get myself warmed up before I held it at my side. The second with Yugo's. He had a bow's riser in his fist now and a quiver had formed on his back armed with plenty of arrows, he looked around, noticing distortions in the air. Finally, Yuri's formed. He had a pistol grip in his palm now, a semi-automatic Smith & Wesson. He cocked the gun and picked up on the distortions as well. He frowned and mumbled something to me before I nodded quietly. This wasn't going to be a regular Tengu, it seemed.

For now, we prepared ourselves for the worst and had the air around us thicken as the Tengu made it's presence known. The impish goblin soon let out a loud call and spread it's wings before it bared it's talons and lunged at us. I grit my teeth as the goblin approached rapidly, making sure to lock onto us. If it missed, it was going to lunge at the person nearby. I looked to Yuri and Yugo, who nodded and prepared to jump away. When it was close enough, we all parted and leaped into different directions. We had picked up and verified that this was a tainted goblin. I soon grimaced when miasma started forming in the air, Yugo immediately covered his mouth and held his breath while Yuri just scowled and covered his face with a mask he had. I soon ended up tugging out a mask myself and pulling it over my face, it was a military mask. Yugo pulled his own mask out and covered his face before he jerked his head at Yuri. We were going to have more trouble than we really could afford.

(1) - A Tengu is Japanese impish goblin that resides in mountains. They were orignally hypocritical priests who were cursed to be bird-like creatures for the rest of their lives. They're tricksters and usually end up doing things like tying priests to poles, burning temples and kidnapping children.

(2) - The carpus is the bone that sticks out of your wrist.

(3) - "Dorsum" is the medical term used for the back of your hand.

(4) A shikomizue is a Japanese sword. The name shikomi-zue is actually the name of a type of mounting; the sword blade was placed in a cane-like mounting (tsue) as concealment.
