"There are two things that you can do in this place," Yamaguchi started to explain to them what kind of things they could do here."What is that?" Yukana asked.
"First you can go diving in this place," Yamaguchi explained and pointed her finger toward an island that could be seen from their manor, "You can see that desolate island, right? That place is Yorioyajima. 200 meters east of the island, there"s ruin the seabed."
"Is that a seabed palace?" Kuina said.
"Seabed palace?"
Kuina nodded, "Yes, I"ve heard that there is someone who has found a treasure in that place."
"Treasure?!" They were surprised when they heard about a treasure that was found on that island.
Yamaguchi sighed, "Yes, two weeks ago there was someone who has found a treasure in that place and that is why there are a lot of treasure hunters in this place."
"Will they cause trouble?" Yuuki asked.
Yamaguchi hurriedly shook her head, "Don"t worry, they don"t cause trouble and they only go to the sea to search for the treasure. They don"t communicate that much with the people around them but when you meet them it is better not to bother them since they"re a bit rough."
They nodded but they didn"t seem that worried since they had someone who protected them.
"Then what is the other thing?" Utaha asked.
"There is a treasure hunt event that is held on this island, you can visit the museum and enter the event together later solving the mystery in this island," Yamaguchi introduced and asked, "Do you want to try it?"
"Yes, but let"s do it tomorrow since we have something to do now," Yuuki said.
"Oh? What is it?" Yamaguchi asked.
"Enjoying the beach!"
---
There is a beautiful and clear beach in front of their manor and it will be a shame for them to not play on the beach.
Yuuki might want to tan his skin and rested on the beach resting on the chair.
Yamaguchi, who saw his face, couldn"t help but stunned, "E - Excuse me, are you Ichijou Yuuki?"
Yuuki didn"t wear his gla.s.ses, "Yes, is there something?"
"I am your fan!" Yamaguchi was excited and started to tell him a lot of things.
"...." Yuuki was wondering whether he should wear his gla.s.ses later. He only wanted to have a holiday but didn"t expect to meet his fans in this far away island.
They talked about each other and he was quite curious about the seabed palace.
"Ten years ago, there was a rumor saying that there was a ruin near Koumi Island. Many scholars came to do research, but no conclusions have been made yet as to whether it"s man-made or natural."
"Yorioyajima used to be exposed to water. It sank into the sea 300 years ago due to the earthquakes," Yamaguchi explained.
"Due to earthquakes? Like in a landslide?" Akane asked.
"Yes, I"ve heard that the seabed nearby contains methane hydrate. The earthquakes disturbed it and caused a landslide. That"s the most convincing explanation," Yamaguchi said.
"M - Meth- what?" Ranko was confused.
"Methane hydrate," Yuuki said.
"In a low temperature, high-pressure environment, water combines with methane and all sorts of forms of the cage. It"s called combustible ice," Haibara explained.
"....." They didn"t understand what she was saying.
"You"ve built a house of cards, right? Water builds a house like that and each room contains methane. When the temperature rises or when the pressure falls, it"ll become unstable, and the whole thing will collapse, releasing the methane," Yuuki explained.
They nodded when they heard his explanation.
"Enough of that, let"s just play on the beach!" Ranko said and pulled him to the beach.
Yuuki didn"t reject her and also joined her in playing in the water.
They might have seen his body for a long time but they had to admit that he was very hot.
Yamaguchi only knew that the idol that was often appearing on the television had such a large tattoo on his body and had a large number of harems in this place.
---
They had a long time on the beach from swimming, playing volleyball, or flirting and as expected that they had become quite hungry.
Yamaguchi helped with the preparation of the food and told them about the traditional foods from the southern part of this country such as chanpuruu and rafute.
The taste was quite good and their first day staying in this place was very nice and they couldn"t wait for the next day since they would be going to explore the town trying the treasure hunt game and tried to dive into the sea.
The majority of the people had slept early since they were tired from their journey.
Yuuki was in the bath right now and he had to admit the size of this bathroom was very large and there was an onsen too.
"Excuse me."
Kuroka and Akeno entered the bath together and washed their bodies, joining him to take a bath.
"It feels good," they said at the same time.
"How is it?" Yuuki asked.
"It"s good, nyaa, Shirone also make a lot of friends," Kuroka said.

"Yes, this trip was very nice," Akeno nodded.
"Is there trouble in Kuoh?" Yuuki asked.
"Well, it isn"t much, but usually there are a lot of strays that are coming to cause a ruckus there," Akeno said.
"Stray is everywhere, nyaa, not all of the high-rank devils have a very nice personality similar to your master, most of them have a very bad personality and very arrogant, nyaa," Kuroka said.
"Well, I can"t deny that....." Akeno sighed.
"This world isn"t perfect, even in the human world there are a lot of similar things happening every day, rather than thinking something like that why don"t we enjoy our holiday?" Yuuki said and hugged their waists.
"In the bathroom, nyaa?" Kuroka asked.
"Why not? I think this is quite fun," Akeno said.
"Well, let"s do it shall we?"
