A white gap was cut in the blue sea.

The black-haired boy stood on the deck with his hands in his pockets, staring into the distance through the lenses on the bridge of his nose, not knowing what he was thinking, and the beautiful scenery of the sea and sky did not seem to impress him, but made his expression more and more solemn, and even his lips were tightly pursed.

There, where the sky meets the sea, a dark shadow gradually appeared.

Blackgod Island.

He silently recited its name in his mind.

With an area of 3.13 square kilometers and a coastline of 7.9 kilometers, the island is home to 50 permanent residents, and is a popular tourist island with its strong Ryukyu style and naturally formed stalactite caves, with about 50,000 tourists visiting the island every year.

He knew all the information he could find in the brochures. But this did not make him any more relaxed, and even more nervous and vigilant than usual, because of the dark letterhead signed "Maji Mingjia" lying in the inner pocket of his trench coat, and the island's other unknown name, Onijin Island.

Yes, this teenager - rather a girl - is Naotome Saotome, a police officer in the cross-dressing Childcare Division.

The reason why this island is vaguely called Onijin Island is due to an incident that happened ten years ago.

Ten years ago, when Nao was three years old, a case occurred on the island of Kurojin that shocked the whole country: a man who was known to be honest and honest went berserk for some reason, carried a firewood knife and hacked eleven residents of the island, including his own family, and then escaped, and disappeared into the stalactite cave on the island. Although the body of his suicide was eventually found in the cave, five of the victims never opened their eyes again. After the police investigation, they found that the murderer did not have any mental problems, and he could not explain his motive for killing, and since then there have been rumors that the man was possessed by a demon so he opened a killing spree, and this island has also become an ominous "island of ghosts" in the eyes of nearby residents, and until now, only some tourists who do not care or know about it will come to the island, and Okinawan locals, especially the older ones, will not come close to this place at all.

As a police officer who uses evidence to uncover the truth of a qiē, Nao doesn't believe in rumors such as "ghost possession" at all, so she firmly believes that in the case ten years ago, there must be some clues or tricks that have not been noticed.

Like the riddle-like poem on this black letterhead, there is a magic that ignites curiosity and excitement in the heart.

Simple and pure people.

People with beautiful eyes.

Don't look sideways for money,

The golden flower of the black god is not money!

The flower of money will one day wither, and the true flower of gold will bloom.

Don't give up the heart of gold, the true golden flower of the black god will bloom -

The old boatman at the helm opened his throat and sang simple and beautiful folk songs, accompanied by the clear blue sky and blue sea, which made people's hearts open.

The lyrics are in an obscure Ryukyu dialect, but the tune is very simple. The passengers in the cabin listened and couldn't help but whisper along with the tune.

Chilling, Nao slipped into the cabin and sat down on a humble bench. The cabin was small, with only three people on narrow benches, as well as opposite. Since it's not the peak tourist season, there are no regular boats between the main island of Okinawa and Kurosami Island, so even this small fishing boat, which can only accommodate six passengers, needs to be booked a day in advance.

There were four people in the cabin plus Nao himself. Sitting next to Nao was a middle-aged man with a stern face. He wore a pair of gray pants with the cuffs tucked into his boots. He wears a dark blue jacket on his upper body, and has a swarthy face with a mustache, which seems to be extremely unapproachable.

On the opposite side were a man and a woman about her age. The boy holding a book and reading has short fluffy brown hair and a red plaid scarf, while the girl has a black reddish double ponytail and beautiful big eyes are looking at Nao's face that is half covered by sunglasses.

Nao's heart jumped, and she quietly looked away.

The girl didn't seem to care about Nao's coldness, but opened her mouth with a smile as if she had seen something pleasing to the eye.

"Now, Ni-chan, you're here for a trip too?"

"Yes. Nao replied casually as she leaned back in her chair with her eyes half-closed.

"What's so interesting about this island, not only my brother, but also my father. Isn't it just an island?"

The girl said nonchalantly.

Dad?Nao opened his eyes and looked sideways at the middle-aged man with a straight face beside him.

"No, no, no!" the girl raised a hand and waved it vigorously, her short double ponytail swaying back and forth like the ears of some small animal, "My dad doesn't have time, so it's just me and my brother going to the island this time! ”

"Yes," Nao looked at the girl in front of him who was almost the same age as Natsu and the boy who was not much older than her, and the corners of Nao's mouth curled slightly, "Then be careful." The island has a hot and humid climate, with a lot of insects, snakes and poisonous plants, and getting bitten is no fun. ”

"It's okay! This guy is an expert at this!"

The girl patted the young man next to her on the back vigorously, baring her teeth and smiling proudly. There was a heart-pounding sound at the point of contact with the flesh.

The boy was caught off guard and plunged headlong into the page, and immediately coughed loudly.

"Did I say you're going to murder!"

The boy raised his head and showed a handsome face, but his expression was not so stylish at this time.

"Really...... It was noisy all the way, and it was rare to be quiet for a while. He pressed down the green tendons that burst from the corners of his forehead and smiled apologetically at Nao, "I'm so sorry, this kid is always so noisy." ”

"How can I be noisy!" the girl pouted and retorted dissatisfiedly, "Xiao Zang is the same, just like an old man at the age of thirteen, he is decrepit before he gets old!"

"It's all said, don't call me Xiaozang......"

"It's going to be called! Xiao Zang Xiao Zang Xiao Zang Xiao Zang - !!"

"やかましい (Noisy) ......"

The boy sighed and pressed the corner of his forehead again, it seemed that this was his habitual movement.

Nao twitched the corners of her mouth and closed her eyes sympathetically.

It looks like my sister is the cutest...... She thought to herself.

Just as she was thinking crankily with the sigh of the young man opposite, the long whistle suddenly sounded in everyone's ears.

“...... Has it already arrived?"

Nao opened his eyes, pulled up the sleeve of his left hand and looked at the watch, the hour hand on the dial was placed exactly in the middle of nine and ten.

However, she didn't notice the surprised expression of the young man opposite when he saw her left hand.

The port lounge on Kurosami Island is a very simple hut, and the walled building next to it is where the island's tourism class is located. The two houses are built side by side, creating a wonderful atmosphere where the style of the Showa period and the Ryukyu atmosphere coexist.

"The air is so fresh! It's like suddenly going back to 60 years ago. Uh-huh~ecstasy-!!"

The handsome young man stretched, his short almost silver hair glistening in the sunlight. The girl next to him muttered, "It's like an old man," with a look of disgust.

Before getting off the boat, the two siblings and Nao introduced each other. Both of them, surnamed Shiraishi, are siblings — the elder brother's name is Kuranosuke and the younger sister's name is Tomokari — who came to Okinawa from Osaka for spring break. My father's profession was a pharmacist. I came to Kurosami Island to replace my father, who couldn't come, to investigate on a small island with well-preserved natural scenery and look for some plants with special effects.

It is worth mentioning that for some reason, Nao's name when he introduced himself was "Matsuda Uchizosuke", and his identity was a second-year student affiliated to Lihai University.

"I didn't expect us to even book a hotel!"

Yukari ignored her brother, who was intoxicated by the fresh air with his eyes closed, and raised his face and asked excitedly, "Now, Matsuda-chan, are we going straight to the hotel?"

Nao nodded, "There are no buses on this island, and it will be almost noon when we get there, just in time for lunch." ”

"It's so natural!" Touka stuck out her tongue.

According to the map, walk east from the trail in front of the Tourism Division, where the hotel they booked.

The temperature in spring is not very high, but the sunlight that shines directly on the ground through the clear atmosphere is not so gentle. Especially this is a very small island. Not only overhead, but also the light reflected from the surrounding sea also warmed it up. Walking on the unsheltered dirt road, the scorching sun scorched overhead, as if you could hear the burning sound of your hair and shoulders.

Fortunately, it didn't take long for a large area of shade to fall overhead. The surroundings suddenly became dark.

But in contrast to the cool temperatures, the road beneath your feet became bumpy.

"Haven't you arrived yet?"

Yuka pulled out a handkerchief and wiped her sweat, and by the way, wiped the dirt off her palms—she had just tripped over the bulging roots.

"It's almost there. Nao, who was walking at the front, replied, "There should be a shrine in front of you, and you should be able to see it not far after the shrine." ”

At the end of the line, Shiraishi was carrying a huge canvas bag, his expression was quite relaxed, and the light of the forest cast patches of light on the snow-white bandage on his left forearm.

"I didn't expect this island to be small, and there should be no less. He spread out the tour map in his hand, "The fork in the road we passed just now has not only souvenir shops and barbecue spots, but also two homestays. It looks like the hostel we booked was the furthest away...... Well, who makes the best scenery here? ”

"That's right, the 'Akanehama Pavilion' we are going to is built on the highest part of Kurosami Island, not far from the cliff and the lighthouse, not only can you overlook the whole island, but you can also enjoy the birds of the outlying islands from the cliff, and even the morning sun and sunset are more beautiful than other places. ”

Nao said with his back to the two, but his eyes under the sunglasses flashed with a sharp light for a moment, "...... In addition, the owner of the inn, Boss Matayoshi, also cooks authentic Ryukyu cuisine. ”

"That's great...... Yuka gasped and swallowed hard, "I really want to eat ground bean tofu, I ate it once in Naha last time, it's very delicious!"

"Then let's hurry up! There's a shrine in front of you. ”

Nao chuckled in encouragement.

After nine or ten minutes of walking through the woods, my eyes suddenly brightened and my vision widened. The path at your feet curved in a shallow arc, and between the edge of the trees and the crashing cliffs stood a brown-red building surrounded by stone walls.

"That's 'Akamahama Pavilion'. ”

Closing the sightseeing map in his hand, Nao narrowed his eyes.

"Akahamata-tei" is a traditional Ryukyu-style wooden house. The triangular brick-colored roof has deep ravines, flat eaves, high ridges, and a stone carving of "Tang Lion" with a large head and a thin body stands on the tiles. In order to protect against the typhoon, the high stone wall almost blocked the entire house, revealing only the eaves and half of the walls. Just looking at it, it is as if you have stepped into the era of the Ryukyu Dynasty a hundred years ago.

"That's good. Yukari's eyes widened.

"Compared to other parts of Okinawa, this is one of the best-preserved Ryukyu buildings. Nao said as he walked towards the guesthouse.

Bypassing the courtyard wall about one and a half meters high, the group walked into the small courtyard of the homestay.

The surroundings are very quiet, and it seems that no one lives here, and only from the wooden sign that reads "Akanehama Pavilion" placed at the entrance of the courtyard can tell that this is indeed the place they are looking for. Nao opened what looked like the wooden door of the main house and was the first to enter the room.

"Excuse me, is anyone there?"

"Ah, yes. Welcome. ”

As soon as Nao's words fell, hurried footsteps came from inside the room, and a woman in a kimono with small floral sleeves emerged from the other end of the hallway—she looked to be in her thirties, with snow-white skin that matched the climate here, and her long black hair hanging down in a bun. The body is light and graceful, and she smiles at the corners of her lips when she speaks, and she is an out-and-out beauty.

"When we first met, I was the owner of this place, Mie Matayoshi. The beauty owed, and raised her head to look at the three of them, "How many of you are?"

"I'm Kurasuke Matsuda, who booked the room before. The two here are the same as Kuranosuke Shiraishi and Yukari Shiraishi. ”

"Yes, there is. Matayoshi Mieda said, bowing again, "It's hard to come from afar, I'll assign you a room right away." Do you need lunch here?"

"That's right. ”

Nao looked at her without a trace, and said, "I heard that the local cuisine of Boss Mataji Mingjia here is quite good, and it would be great if you could taste it for lunch." ”

"Yes, I want to eat ground bean tofu!" said Yuka, whose eyes lit up as she breathed away, cheered.

Mieda's body stiffened suddenly when she heard this, and Fuer lowered her head deeply, her voice becoming choked.

"I'm sorry...... The master, Yoshimeika, had passed away a week ago. ”

A week ago?!

At the moment when the last word was spat out, Nao's breath stagnated, and her pupils shrank tightly together as if they had been pricked by a needle.
