Matsuoka has been pacing in his office past few two hours. Outside his office, his co-workers stared at the young detective, including Nagisa and Tatsuya who has been following the sight of the violet that has been acting…strange…

"Tell me, how the hell you followed me here?!" Matsuoka said as he spoke to the ghostly jet black haired teen that has been floating around his office, to be exact, Mizuki.

"I don't know, you said you want my help so I thought maybe I should follow you, by the way you have great books about swimming here" he replied as he tried to take the book that has caught his attention on the shelves.

"Listen to me!" noticing Mizuki hands went through the book that he just mentioned. He face palmed.

"Why the hell did I even suggest this in the first place, now I got a ghost following me around?!"

"Rin, can you help me grab this book and let me read it?"

"Since when did I allowed you to call me by my given name?"

"Since now" he then went back to the book he was trying to grab. Matsuoka sighed. Whatever he does, it did not scare Mizuki away.

"Rin-chan, are you alright?" Nagisa enters the office looking worried.

"Huh, yeah. Why did ya ask?"

"Uhm…well…you're talking to the air…"

Matsuoka froze. Then he realized everyone was watching him acting like a lunatic in the office talking to no one. Well not exactly no one, but a ghost…

"Did I, I was just practicing my vocal"

Nagisa raised an eyebrow, "Vocal?"

Matsuoka nodded, sweat dropping, hoping the blond would take that as an answer. He quickly made a quick dash towards the book that Mizuki wanted and grabbed his coat, exiting the office, followed by Mizuki behind.

"I gotta go"

~~~~~

It was then in his car,

Passersby were staring strangely at the violet detective who seems to be talking to…someone.

"Okay, let's make a deal shall we?"

Mizuki then went into a sitting pose in the air while nodding, waiting for this 'deal' Matsuoka mentioned.

"You will not talk to me when there is someone around me, I don't care how important it is, YOU WILL NOT TALK unless I say so"

The teen shoulder fell, "In return, I will let you read all these swimming stuff books all you want in my free time, is that a deal?"

Mizuki sea blue orbs lit up, his eyes focused on the book that Matsuoka waving in front of him. The violet smiled at how childish is the teen behavior.

"Is that a deal?"

The teen nodded, Matsuoka smiled. "Well, it's almost late, think I'll grab some dinner, you need any?"

"I don't think ghosts can eat"

Matsuoka eyed the teen who is sitting…well almost floating in the passenger seat next to him. "For some reason…I can't let my eye off him…"

"Oh well, just suck it up, after that I'll be heading home"

Mizuki nodded and just stayed silent throughout the journey, looking outside the window. It was a strange feeling for Matsuoka to have someone in the car and followed him around even going to the diners.

"Is it alright for your body without you there?"

"I guess so…I just followed you without thinking"

"Don't worry, we'll find a way to get you back to your body while solving this case" Matsuoka smiled then focused on driving home.

~~~~~

Mizuki blinks at the sight in front of him, he was not sure if he is in hell or not.

"Your place is a wreck; I'm starting to doubt that you're a detective"

"Shut up, stay here while I get a shower, and don't touch anything!" He warned the teen that was floating around his apartment.

"But I can't touch anything even if I wanted too…" Mizuki trailed off, following the sight of the detective disappearing into a room after throwing his coat onto the couch.

"Is he living alone?"

He floats around the apartment; it's a large place just for one person. It has 3 bedrooms, 2 showers, 1 complete kitchen set, a large living room with all those flat screens and audio speakers.

"It has nice colors…just like his hair…" Mizuki mumbles as he looked at the wall color painted in violet. He then noticed a room with a lot of trophies, medals, certificates and a shelve of swimming books and magazines. It was neatly kept room, unlike other parts of the apartment.

"Was he a swimmer back then…?" He mumbles upon noticing a photo framing a picture of Matsuoka Rin in his younger days holding trophies' with his friends, looking so happy.

"I wonder if I had friends when I was…alive…"

Suddenly,

Flashes of blue water splashing, someone talking to him, flashes of a dark rainy day, flashes of him falling onto the ground, flashes of bloods flowing down on the ground, flashes of someone crying, flashes of a green necktie.

"I'm sorry…"

Mizuki orbs were wide, his chest heaves up and down, panting softly.

"What was that..."

He heard someone bang opens the door, heavy footsteps enters the room

"GET OUT"

~~~~~

"I wonder where should I start first…or maybe I should start with the place they found him or maybe his bags" the violet haired detective mumbles as he washed off the shampoo bubbles on his hair.

"I guess I'll have to start heading to the site first thing tomorrow"

Matsuoka finally finished his shower, noticing the ghost were not anywhere in the apartment then he saw the door towards the room he always kept locked is opened.

"Odd…I don't remember unlocking the door"

He enters, his eyebrow knitted into frowns, the moment he saw Mizuki looking at all the things in there.

"GET OUT" he raised his voice.

"Rin, were yo-"

"I SAID GET OUT OF THIS ROOM"

Mizuki quickly floats out of the room, as far as possible from the angry detective. He could hear the door being shut with much force, as it echoes throughout the entire apartment.

~~~~~

Matsuoka appeared in the living room, Mizuki was floating at the corner. The violet eyed the ghost, he sighed.

"Just don't enter that room anymore"

The ghost heard that small mumble and nodded. They both stayed silent for over 20 minutes. Matsuoka finally gave up and went to the kitchen, reheating whatever food he bought earlier. He could see from the corner of his eyes, Mizuki remained silent even though he is still floating nearby.

"Do you remember anything before you get hurt?"

He broke the heavy silence. Mizuki flinched at the question, Matsuoka noticed this.

"What's wrong?"

After a while of silence, the ghost replied with a sad look on his face.

"W...when I was in that room earlier…I was looking through things…I have a flashback or some sort…"

Matsuoka took a seat at the counter chair, leaning his head against his right knuckles, looking at the floating Mizuki, waiting for him to continue his sentence. Mizuki bit his lip.

"There was guy talking to me in a happy way…then there's rainy night, it was heavy, I fell onto the ground, I saw bloods falling down the ground…and…"

"And…?"

"I heard someone apologizing and ran off using a green necktie…I don't know if it's even my memories…it hurts when I try to recall back…"

The violet detective kept his eyes onto the teen while sipping his coffee.

"If that is his memories, there is a possibility it was an attempt murder…the man he sees in his flashback…that can be either a suspect or a witness or someone he is close to… "He frowns then let out a sigh.

"Just what i got myself into..." he massaged his nose bridge.

"Rin?"

"But to find a certain guy with only a green necktie as descriptions…it's harder than one think…especially with no other descriptions…maybe I should ask HIM, he's good at finding people…"

"Rin…?"

Matsuoka snapped from his train of thoughts, noticing Mizuki got a little closer to him, looking worried.

"Yeah…?"

"Ah nothing…it's just you weren't answering when I called you…" he flinched the moment Matsuoka orbs looked at him. He swallowed the heavy lump that was stuck in his throat.

The violet haired detective stood up as he stretched, dumping his dishes into the sink and headed to his bedroom after grabbing several folders on the table in the living room.

"I'm going to sleep, best if you get some sleep, we got a long day tomorrow"

Mizuki follows him but immediately halt the moment Matsuoka glares at him, just like a lion about to eat their prey. Mizuki floats back a little.

"I don't appreciate having a ghost or anyone in my room while I'm sleeping, so you stay out here, make yourself comfortable at the couch"

The ghost quietly nodded and floats away towards the living room, Matsuoka turns off the lights, leaving Mizuki in the dark living room. The detective watched him floats away from the crack of the door before shutting it close.

"I wonder if I did something to piss him off…." Mizuki mumbles before resting his head on his arms while floating in the air around the living room.

"Ya awake?"

"Yes, I am. What ya need in the middle of the night?"

"Straight forward as ever, aren't you?"

"Stop wasting my time and say it"

"Fine, fine just don't sounds so grumpy will ya?"

"…."

"I'll send you an email, it's locked with a password, and I believe you know the password, read it"

After a moment of silence on the other line of the phone, Matsuoka heard a sigh.

"As usual, you ALWAYS asked for the impossible"

The violet detective grins, "You and your stupid grin"

"Well, think you can do it?"

"When you need this?"

"If possible in less than a week or as soon as you can"

"Expect an email from me soon"

In the room, sprawl all the papers on the bed from the files he brought along earlier. The only light that lit his dark room was from the moonlight. Matsuoka stretched as he lets out a long yawn.

"At this rate, I won't be able to get proper sleep until this case is over" he mumbles, quietly he pokes his head outside his bedroom door, eyeing for a certain ghost.

"Wonder where he is?"

Quietly he exits his room, walking towards the living room. He heard soft breathing echoes in the quiet apartment. He noticed, Mizuki was on the couch, with his arms under his head, eyes shuts close as his bangs falls over to the side.

Matsuoka smiled, his hands was about to brush those bangs off when he realized that Mizuki is not physically there, after he noticed his hands just went through the teen see through body. He sat on the table, looking at the asleep ghost.

"Funny…I never expected I would see a ghost sleeping in my entire life" he rested his head on his left knuckles, staring at Mizuki quietly. His flaring orbs soften.

"I wonder if he was lonely, being in this form…before I came…no memories, no friends, no one that could see him…I know I would be completely lost without any of those…"

He remembered earlier incident where Mizuki went into 'THAT' room, not knowing it was not allowed for outsiders.

"I shouldn't have shouted at him…this is such a pain" he thought. He knew his attitude scares the ghost that made him flinched each time he looked at him. It was not something that Matsuoka proud of.

Mizuki face frowns a little but did not woke up; instead he just curls into a ball, as if protecting himself from whatever harm that may come by to him.

"I really wanna know what happened to you..."

Quietly, he retreated back to his room after giving a final glance to the asleep Mizuki on the couch.

"Goodnight, Mizuki"
