I feel it everyday,
It's all the same,
It brings be down,
But I'm the one to blame.

Shark's PoV

"It's great that you're sitting with me this time, Shark!" A boy sitting across from me cried. Literally inhaling his food. He smiled, "I'm glad we're hanging out more!"

I chuckled lightly, and leaned on the table as I watched him eat. It was amusing. Still though, it's been years ago that he became my friend, and that he is now the only one calling me "Shark" now-a-days. The nickname just died down on other people. Rather they call me "Kamishiro-san" or whatever, I just didn't care. I let only Yuuma call me "Shark" because for one, I see no sign of him growing out of it. For two, it's his sign of affection and friendship towards me. It makes me feel a lot more special to hear that only he gets to call me "Shark", really. I sighed, "Only for you, though."

Silence.

Yuuma gulped down one bite of duel balls, when he grinned towards me, and took out a letter, "Oh yeah! This random guy decided to have me write you a letter! I think it's a duel challenge, or whatever!"

I rose an eyebrow, and took the letter from him. One look at it, and I rolled my eyes, "I think this might be a secret admirer letter, Yuuma. You know I don't read these."

"Well, the dude had me write it, and I think it's a invitation for a duel!" Yuuma cried, "Come on, give it a read!"

I rolled my eyes and sighed, "Fine. Only for you, Yuuma."

I opened the letter, and I gave it I read. Only for me to raise my eyebrow.

"Dear Kamishiro,

I decided to invite you to play a game with me. It won't be long. I feel it everyday that one day you'd be interested into playing with me. No worries though if you can't play. It's all the same, but you will get to play, this Yuuma kid is even interested. Will you play?

-Signed F.U."

I this kid wrote-made Yuuma wrote-it differently, "... F.U, Yuuma?"

Yuuma shrugged, "Dunno. The guy didn't tell me much about himself. He didn't even look right. A grey jacket with both a hat and his hood on? He sure is strange."

I glared at him, "And he made you write this strange letter? Dude, I tell ya, he could be dangerous."

"Look, just accept his so-called "game" and then get it over with," Yuuma sighed, "I bet it won't be too hard. Maybe it's a duel. You're one of the strongest in the school."

Silence.

I sighed, "Fine. Only because you, of all people, asked me too."

"Thanks, Shark!" Yuuma cried, and took his last bite of food, "You're the best!"

Just in time, too. Lunch was over.

Soon, we split up, and waved as we went to our different classes. We'll discuss this business soon too, on how to deal with this F.U. guy. We'll know.

X-X-X-X

It was after school when I got a call from Rio. Sighing, I answered the phone, "What?"

"Ryoga!" She cried, she looked panicked.

I rose an eyebrow, "What's wrong?"

"I-It's Tetsuo!" She replied, "H-He's in the hospital!"

Soon though, I frowned, "I'm on my way!"

I ran as I hung up. I put the D-gazer away, and hoped my feet could carry me there. Since my motorbike was in the repair shop, thanks to a damn accident. I hoped I could make it there in time. If I remember correctly, Tetsuo was one of Yuuma's friends. He is almost like a brother to him. So, I should really be there, just in case. I don't want Yuuma to isolate himself. Everytime someone is gone, Yuuma isolates himself.

I don't want him to do that.

X-X-X-X

Soon, I was in Tetsuo's room, with Tetsuo being unconscious. Each one of my-no, Yuuma's-friends acted differently. Kotori was sobbing into Rio's chest, as Rio was trying to stay strong. The others acted pretty much the same way, crying, and sobbing. Acting as if Tetsuo died. He's still alive, isn't he? I didn't know.

Though, Yuuma was no where to be found.

"How could someone do this!?" One of Yuuma's friends cried. Cat-chan, I believe, "Why would they attack him!?"

"I don't know!" Kotori cried, "Th-There's gotta be a reason!"

Rio sighed, "The only clue is a letter."

This perked my interest, "... A letter?"

Rio nodded, and pointed at an envelope next to Tetsuo's bed, "A letter. Addressed to no one in particular."

I soon walked up to it, and opened it. As I read it over, I growled, obvious anger growing in me.

"Well, well, well. Looks like you found one of my clues. Good for you. It brings me down to tell you that I didn't murder this man, but I'm the one to blame for this. This is only the beginning of my game. Would you continue to play now though?

-Signed, F.U."

I crumpled up the paper, and threw it on the ground, ignoring everyone's gasps and pleas to stop it. It was the only clue to Tetsuo's injury, and I crumpled it up. I didn't care though, as I was pissed with this F.U. guy.

"Ryoga, calm down!" Rio cried, "There's nothing to do!"

"I've received a letter this morning about this F.U. guy!" I blurted out, out of anger, "I'll never forgive him!"

Everyone gasped at this information.

I still had his first letter. I took it out, and slammed it onto Tetsuo's table, "This guy made Yuuma write this damn thing! If you want information, ask him! I'm gonna go find this guy!"

"And how are you gonna find him!?" Rio cried, obvious irritation in her voice, "He could be anywhere right about now!"

I growled, and I walked away, "I'll figure this out!"

Once I left, I bumped into a person outside, I frowned, "Move it!"

"Shark..." A voice squeaked, obvious hurt in his voice, "... Is it true? Is Tetsuo really hurt?"

I stopped as I heard his voice. I turned around only to meet tearful red-eyes.

Silence.

I looked away, growling in frustration, "Yes. He's fine though, just unconscious."

"Shark, where are you going?" Yuuma asked, "Don't you care?"

I growled, "Of course I do! In fact, I'm gonna find a way to find this guy and make him pay!"

"Don't you know how empty revenge is!?" Yuuma cried, obviously upset, "I thought you knew to be nice to people! Fighting isn't the answer!"

Silence.

Of course.

That was one of the first things Yuuma taught me when I first became friends with him.

Of course, all of us knows that Yuuma is incapable of feeling revenge, even for the slightest. Sure, he may get angry, but never vengeful. That, alone is one of Yuuma's weaknesses though. So, Kaito and I feel his revenge for him, even though he doesn't know it. That, alone is a lot better. So, I just looked away, "Yes. I remember."

"Then why are you after this guy!?" Yuuma cried, "We gotta talk this through!"

I sighed, "Yuuma... What IV did was a little forgivable."

Yeah right. I barely forgive him. I only forgave him for Yuuma's sake though.

"Rio is okay, and alive." I said, trying to remain calm, "However, this guy nearly murdered one of your friends. That is unforgivable, Yuuma. That is something I can't forgive anyone for. So, this is different."

Yuuma gasped, "B-But, Shark-"

"-But nothing." I interrupted him, "Let me do this, Yuuma. I promise I won't hurt him, I just want to make him see what he's doing is wrong. Make him pay."

Yuuma looked away, obvious tears in his eyes, "Promise?"

I sighed, "Promise, Yuuma."

Silence.

"Okay..." Yuuma said once he looked convinced, "... Please. Be careful."

I nodded, "I will be."

I ran off, and Yuuma wished me luck. Well, Yuuma has a way of calming me down, huh? I actually know who to call too. With this little evidence, I doubt he's help now. However, later when this F.U. guy strikes, then we may find out who this guy is, and why he's after us in the first place.

I gotta get him on the case. Luckily, I have his number in my D-Gazer.

X-X-X-X

I stood here, waiting impatiently for him to come back with the results so far. Once the door opened, I looked at him, and nodded, "Did you get anything?"

"No." He stated calmly, "This is a mystery, even for me. There's no one with the initials F and U in the city records."

"Strange." I said, and looked down.

"Is Yuuma's friend gonna be okay?" His little brother asked, looking concerned, "He's still alive, right?"

I nodded, "Yeah. He's merely unconscious at the moment right now."

"Good..." He sighed in relief, "... I don't want any of Yuuma's friends murdered."

I nodded in understanding. I still don't get why he still follows his older brother around at his age, but I almost understand. Rio still clings onto me at times when she gets scared. Especially around cats. I sighed though, "Any ideas why he's after us though?"

"No." The older brother replied again, shaking his head, "I doubt any human would be after us unless he's a Numbers Hunter after our Numbers."

I nodded. Makes sense. I do have Numbers 32, Shark Drake. Which could be why he could be after me first. However, Tetsuo doesn't have any Numbers on him. Which that doesn't make sense, unless the attacker is trying to bait us, which so far is working for his favor. We have to be cautious at all times. Or else he may strike again with us. Maybe Yuuma may know something, as he have seen the guy before.

I decided to call him, only to get another person. My eyes widen when I saw him.

I remembered Yuuma's description of him. Grey hood with a hat and his hood on. Could this be... Him?

"This boy sure is a fool to leave his D-Gazer, huh?" He smirked, "We finally meet face to face, Kamishiro-san!"

His voice sounded forced, and deep. I got a glimps of his eye color.

An orange color.

However, something about them was off.

I stood up, and growled, "Who are you!? Why'd you attack our friend!?"

"That was a warning, Kamishiro-san." He stated, and held up five cards, "You have 5 tries to guess what I'm gonna do. If you're gonna play my game, then you better choose wisely. You wanna hear my rules?"

I glanced at my partner next to me, and he was at his computer recording this. He nodded.

I looked at this guy, "Go ahead."

"Good." He said, and chuckled darkly, "I only have so little time before the fool comes back, so listen up. Have your little friend record this if you have to."

My eyes widen, and all of us looked around the room. He's watching us right now!? Shit!

"You guys are amusing right now!" He laughed, "Don't worry. My target is you, and only you, Kamishiro-san."

I growled, and glared at him, "Just tell us you're damn rules so we can get this so-called "game" over with, you jerk!"

"With pleasure, dear Kamishiro-san." He mused, smirking, "Rule number one though is stay on my good side. Which means, be patient with me, or else I may strike again. Rule two is one guess at a time. Meaning one day, you can make a guess to what I'm doing, and why I'm after you, and only you. Rule three is that you can get your so-called "friends" to help. So, your little friend there could help as much as he wants... Though, he may not like the results..."

I wanted the punch the bastard, "What the hell do you mean!?"

"I mean he may not... Like the results I give you and him..." He stated, chuckling darkly, "For each card incorrect represents a friend... And their disappearance..."

My eyes widen, "What...!? You better not touch Yuuma!"

"Oh, I won't..." He said, glancing away. Assuming to where Yuuma left.

I sighed in relief.

However, it was short-lived.

"He'll be "dead" last!" He cried, and laughed.

We all gasped, and soon anger filled our veins. Soon, we heard yelling in the background.

"That's my cue." He smirked, "Talk to you REAL soon, Kamishiro-san."

He hung-up.

Silence.

I growled, and slammed my D-Gazer to the ground. I didn't care if I broke it or not. I was pissed.

"I recorded the whole call, Ryoga." My partner said, also pissed, "Don't break the evidence."

I glared at him, "How am I suppose to remain calm when there's a guy on our tail on the verge of murdering one of our friends!? Not to mention, you are one of his targets too!"

"I can take care of myself." He stated calmly, "It's you who he's after, remember?"

I growled, "I know, but I can take care of myself too!"

"Look, we gotta figure this out." He stated, "If we don't, then it'll be too late, and we'll lose Yuuma."

Silence.

He's right.

We gotta play this game so that way we could protect Yuuma. Soon though, I growled, and looked around.

"Ya hear that!? We'll play your da-darn game!" I yelled, making sure I don't curse in front of my partner's little brother, "You better watch your back! You'll pay for what you've done!"

I could practically hear him laugh. That bastard.

Soon though, as my partner picked up the D-Gazer, I started to pace, just to calm myself down. This guy serious has me worked up.

I can't believe we agreed to this.

But it was the only way to protect Yuuma.
