"But man! Jou-chan is amazing! How did she able to get out from that sealed hellish place?!" Bou-san exclaimed. Three days after the case, the SPR irregulars decided to visit the office, to asked Mai questions, but only to find that she took a leave.

Naru was taking a break in the common when they arrived. It's no use in fleeing back to his office, especially when Gene was glaring at him now and then, he knew he was irritated since he go out with Masako last night... again.

So he stayed and subtly listening to their discussion about yesterday's case.

"Maybe she broke the wall?" Ayako shrugged.

Bou-san gave her a look. "Okay? How? It even took several of us breaking the wall remember?"

"Maybe Mai-san has a PK?" John thought.

"Hm. Possibly." Bou-san nodded, contemplating the idea of PK.

Naru unconsciously gripped the necklace under the collar of his shirt. He knew how she managed to get out, Mai borrowed some of his PK ability. His and Mai's necklace were linked, thanks to Phoebe's spells, they can borrow each other's ability in a minimum amount, and only for a moment.

"By the way, where is she?" Ayako asked Gene.

"Hm? She and Daniel went on a trip." He smiled at the miko.

"Oh, she goes with her brother for sightseeing? That sounds fun! I haven't done a sightseeing for a while." Bou-san dreamingly stated.

Gene tried to smile at them, knowing what kind of trip that the siblings were having.

Mai sighed dejectedly, comparing the view of the lake in front of her to the drawing of the lake in her hands, and shook her head at her brother, who, in return, marking an 'X' on the map.

"I wanted to find her soon, Dan... She needed a proper burial, and for Di's grieving family as well..."

"We will find her Mai..." He assured her. "Did you even tried on calling her spirit?"

She nodded and sighed. "But she won't even answer either Lin or Gene's summoning."

"Maybe she already moved on?"

"I hope so."

Daniel sighed and admire the nature's beauty before him. "Come on, I'm hungry! Let's take a lunch break first before going to another location, we can't fight with an empty stomach, you know." He joked, trying to ease the gloomy atmosphere between them.

Mai chuckled and climbed into the car that he rented. They drive for a while before Daniel parked the red sports car in the parking lot next to a local diner they saw on their way back. The atmosphere in the place was homey.

The two took their order and have a little chat with the waiter.

"A lake?" The waiter asked. "Yes, there's a lake nearby, but before you will get there, you will pass thru a tunnel. But people said you will see an apparition of a child and other entities."

"Is the lake looked like this?" Daniel showed her a picture.

The waitress cocked her head. "Kinda... but I'm not sure..." She shrugged. "I'm afraid of the tunnel, so I haven't gone there."

"I see... Thank you." He smiled, the waitress blushed and smiled back, before going to the counter for their order.

"Be careful, you're flirting aura is showing, brother." Mai smirked at him.

"I'm not. I just smiled at her."

She rolled her eyes. "Right."

"By the way... What's your plan after graduation? You're going home next week to pass your thesis, right?"

Mai nodded. "Yeah, and then I'll take a licensure examination in psychology, then help those emotionally unstable clients in BSPR."

"So... it means, you will no longer come back here after your graduation?"

Mai paused from playing the straw in her drink and looked at her lap. "I... I... Uhm..."

Daniel softly smiled at her fidgetting sister. "I understand." Mai's head shot up and stared at her brother askance.

"You want to stay by his side and help him."

Mai blushed furiously and looked away from her brother's teasing look. "I want to help them find her..." She mumbled. "I also promise Aunt Lily that we will find Diana."

"If that's what you want then." Daniel finally said, patting her head. "I trust you."

"Thank you."

"Is this the tunnel that the waitress was talking about?" Mai asked confusedly when she saw the eerie looking tunnel ahead of them.

Daniel slowed down a little. "Yeah, I think so."

The older brother drove into the dark tunnel, it was dark... They tried to remain calm throughout the ride when suddenly, a cat jumped in front of them, Mai shrieked, covering her eyes, as Daniel swivel the wheel trying to avoid the cat, twist, and turns before he maneuvered the car to the side before it made a full stop.

Mai panted heavily. Daniel gripped the wheel tightly, cursing under his breath, he almost got them into an accident.

The siblings let out a startled scream when someone's knocking on the driver seat's mirror. The glass was tinted, and the tunnel was dark... so how come they can see a silhouette of a young boy outside?

Mai gripped his arm when he was about to open the window to look outside. Daniel shot her a confused look, Mai softly shook her head.

"D-D-Drive!" She ordered, stuttering when the knocking became persistent and not only one, but several people knocking on their car.

Daniel fumbled on the keys to start the engine.

"Hurry!" Mai practically yelled.

"My... hands..." Daniel stuttered. He felt his hand stiffen, and someone... someone took over the wheels.

"Kyaaa! Dan! What are you doing?!" Mai exclaimed when the car crisscrossed in the dark tunnel, with only the faint headlights illuminating the way.

"It's not me!" He yelled in horror. "Mai, someone else is driving! I can't move my body!"

Mai's eyes widen when she saw the end of the tunnel - it's a curvy road and it's on the blind spot. Mai took the wheels, and turn the car to the right.

Crashing them onto the concrete barrier.

Naru jerked from his chair when he felt a sudden jolt throughout his body, and his necklace felt warm.

"Damnation! Trust those two to find trouble!" Naru exclaimed irritably. "What could've happened for her to borrow my PK?!"

As if answering his question, he received a message from Mai telling him about their accident.

Mai intuition was telling her that it has something to do with the car that they rented. He asked Naru to find any road related accidents in the area, lo and behold, he found not just one but two reports.

"What is it?" Gene asked he was reading a potential client when he heard Naru exclaim.

"Those two got in a supernatural incident just now. They halt their search and stayed in an inn for a night." He told him about their accident, thankful that Mai used her... err... Naru's PK as a buffer and nothing serious happened to the two of them.

"Whoa there! They are like, in Kyoto right now, right? And they rented the car in Tokyo?"

"Yeah..." He said, glaring at the article online. Stating that a body of a boy was seen in the cliff, near the tunnel, a victim of a hit and run.

Gene widened his eyes in disbelief when he saw the article. "What the hell?!"

"Exactly." He spat bitterly.

He took his phone on the table and called Mai, hoping that none of those vengeful ghosts will harm them because they're riding the car that killed them.

Mai reached her pocket when it finally rang, they're in the Fuwa Ryokan, they will stay here for a night and asked Naru to come and get them in the morning, using the SPR's van. The siblings were in the inn's pond, feeding the koi while waiting for Naru's call after telling him their ghostly encounters.

She immediately put him on a loudspeaker.

"Yes?"

"The two of you are idiots."

The Taniyama siblings raised their eyebrows. "Excuse me...?" They chorused.

Naru sighed on the other line. "The car that you rented already claimed two lives."

Daniel choked on his drink. "WHAT?!" He exclaimed.

"Yes, you heard me right, I have no intention of repeating myself."

"You idiot!" Daniel growled.

"The first victim that the car killed was a boy, an elementary school boy, and his body was found in the road near the tunnel."

"What... what was the boy looked like? Is he wearing a cap?" He asked nervously.

"Yes."

Daniel heaved a sigh. "That's the kid who took over the wheels who almost got us in an accident."

"It's because you are stupid in refusing to borrow the company's van."

"Oh shut up, narcissist!" Daniel rolled his eyes.

"Mai." He called, ignoring the older brother.

"Yes, Naru?"

"We will be there early morning."

"Okay... be careful."

Naru smirk on the other line. "Don't worry, I'm not stupid."

"Jerk!"

Mai exclaimed, huffing angrily before ending the call.

The loud music from the stereo was the first thing that caught her attention, Mai was sitting on the passenger seat, next to her was a teenager, or at least that's what how she perceived him, laughing and drinking a can of beer.

Drunk driving. Mai noted.

She looked in the mirror, her eyes widen in shock when she looked familiar. It was the guy who rented them the car!

"Retsu, you've been drinking non-stop." She sighed shaking her head.

"Ahw! Don't be such a sissy! We just came from a party and I'm just extending it."

Mai started to get nervous when they entered the tunnel. "Be careful Retsu, it's quite dark."

The teenager laughed. "It's alright~ It's alright~ I got this!"

Her friend was not paying attention when a kid suddenly crossed the road.

"RETSU! Watch out!"

Too late. The kid was tossed in the road, and the impact killed him immediately.

"Oh my god! Retsu, what have you done?!"

The teenager was trembling in fear.

"No! No! I didn't mean it! I didn't mean it!" He cried. "Help me. I don't want to be put in jail! There are lots of things I wanted to do! I can't be put in jail!"

Mai sighed and went out from the car watching his friend drag the young boy's body down the cliff to make it looked like that accidentally fell from above.

The scene changed, she's now in a car rental office and saw the familiar man. It was the same person that she and brother met in Tokyo when they rented a car, Wakamatsu Kanata.

"Ka-chan!"

The familiar teenager barged in.

"Retsu? What's wrong?"

"Ka-chan, h-help me... again." He cried. "I really didn't mean this time, he just... he just suddenly came out from nowhere." He rumbled incoherent words.

"Retsu, calm down. Tell me what happen."

"A... kid..." He choked out. His friend widened his eyes. "I killed a kid... I took the body with me... Ka-chan, please help me bury her... the evidence."

"What the hell, Retsu!" He yelled. "I won't help you this time, deal it on your own."

The teenager glared at him. "Fine! You ungrateful friend!"

Mai saw the man Retsu drive in an abandon place, he dig a hole in the ground and just like that, he buried the little girl's body.

And Wakamatsu Kanata transferred to Tokyo, and the car was in his possession.

Mai slowly opened her eyes, she was startled when she saw the little girl standing in front of her.

"Onee-chan..."Her silky voice gave her goose bumps. "Help me... I want to go home... to my mother and father." A tear rolled on her cheeks.

"Yes... Just wait a little longer, okay?"

The ghost of the girl nodded before it fades away.

Mai immediately dialed Naru's number to ask him a favor, and that's to bring Wakamatsu Kanata with them in Kyoto at all cost.

"Good morning, okyaku-sama."

A waitress... err... waiter, open the door.

"My name is Fuwa Sho, and I'm the son of the owner of the inn." He introduced himself. Mai slightly frown at him, being a psychologist and everything, she's quite good in reading people behavior.

"Oh..."

"Do you wish to have your breakfast here, or in the dining hall, ma'am?"

"In the dining hall. I'll have my breakfast together with my brother."

"Understood."

Sho bowed before he left the room.

"Wow, it must be hard for him to be polite."

Mai snorted.
