Meena, brother Silvio and sister Elinora, who bent down to the edge of the waves, gently put their fingers to the seawater. Then the three of them brought it up to their mouths in a fearful manner.

It's salty.

　The three of them let out their perfectly natural impressions.

　That's right. That's because it's salt water.

"You really can't drink sea water, can you?

　Sister Elinora returned with a frown, but Meena and Brother Silvio were still poking at the seawater.

　Then they licked their fingers to make sure again.

'It's still salty.'

Yes.

　They frowned and laughed at each other.

　Behaviorally, the second time around is pointless, but I could tell that they were really enjoying the unknown sea. They both look like they are having a great time.

　The first time I went to the sea in my past life, I also wondered why the seawater was so salty, and I licked it over and over again.

Why is ocean water so salty?

Hmm, I don't know.

　After a few licks, they both tilt their heads in question the next time.

　Hearing this, I take the opportunity to poke Eric next to me.

"Look, Eric. Why is the ocean water so salty?　Tell me about it, okay?

　As I said this, Meena and brother Silvio gave Eric an expectant look. And Eric felt it and looked awkward.

'I don't know why seawater is so salty. Or rather, it's more accurate to say that no one has quite figured out why yet.

'Oh, I see.'

　Meena's voice, which is ministering, seems a little disappointed, although she is convinced.

''........I heard there are people who are studying it, but I still don't understand why seawater is salty.

　Luna says as she adds to Eric's words.

　As I recall, in my previous life's knowledge, the rain of hydrochloric acid dissolved the sodium and magnesium-containing rocks on the surface of the earth, and a neutralization reaction occurred between the hydrochloric acid and the sodium, resulting in salt. This caused the salty water to flow into the ocean and accumulate. I'm sure that was the reason.

　However, in a world where science is not so well developed, there are many things that have yet to be understood. It's no wonder that we don't understand.

　Anyway, we don't know. With that kind of conviction, everyone starts to walk as if to dissipate the delicate air.

　Then Meena, who was walking in front of them, sees something in front of her and proceeds at a small run.

''What is this white thing?''

Shells, I think.

　Brother Silvio must have known this as knowledge. He went to the side and crouched down to stare.

'Right. It's a shell.'

It's nothing like the shells you find in the river in Coriat Village or whatever.

'Most of the shells in the village are brown, aren't they?

　Brother Silvio is right, you're right, most of the shells in the river are brown. Like tanishes, stone shells, and sakamaki mussels. Compared to that, the shells in the sea seem to have a wide variety of colors and types.

　I hadn't thought about it before, but it's interesting to think about it again.

'The shells over here are beautiful with a rainbow of colors inside!　

It's true. Since we're here, why don't we pick up a few shells?

Yes!

Well, I'll help you with that.

　I love finding beautiful shells. Finding a beautiful shell in the middle of a vast beach is somewhat like a treasure hunt, which is interesting.

　As the three of us search for shells on the beach, Elinora, Eric, and Luna join us in our search.

　Only Sister Elinora says, "What do you want in a seashell? He looked at me like he was going to, but I didn't care.

　We each scattered as we extended our search for each other.

　As we walked along, observing the ground with Tototete, I saw a white shell fall.

　It's a neatly wrapped seashell, white as soft-serve ice cream.

'Whoa, this is beautiful,'

　It's very clean, with no holes in it.

　I plucked it up and observed it, and a creature that looked like a hermit crab peeked out from inside the hole.

''........I see, so you already live here.

　It was a very beautiful shell, but if the residents were already there, it was no use. As expected, I wouldn't want it until I kicked the residents inside out.

''Excuse me.''

　I slowly lowered the white conch down to the beach, and as I walked around looking for the next shell, I heard Brother Silvio scream.

'Whoa!　There's something in there!

Haha, hermit crabs. They're creatures that live in shells.

　Brother Silvio was in the same state as me, and Eric laughed lightly as he explained to me.

　I know there's such a creature, so it's fine, but for someone who didn't know and picked it up, they'd be freaked out that a creepy creature came out of the inside. And if it's a demon or something, it won't be fashionable.

"Hey, Luna. Can these shells be eaten?

''Well most of them are small and not very good to eat. But the shellfish they serve for dinner are big and delicious, so keep your hopes up.

All right. I'm looking forward to it.

　Sister Elinora, I'm collecting beautiful shells right now........

''I've been wondering about it since a while ago, but what you're wearing around Luna-sama's neck is a shell necklace, right?

　Hearing Meena's words, I looked at Luna's neck and saw a necklace with a string of white pearls and a pale light blue shell as an accent.

　It's beautiful because it matches Luna-san's skin, which is tanned to a wheat color.

'.........In this village, seashells processed into necklaces are a specialty. If you like it, you can go to the store later and buy one. I'm sure she'll be more accommodating if I mention my name.

'Really?　I'll go there later!

　It's the kind of speciality only a village with the sea nearby can offer.

　Although Luna-san is a friend of Elinora sister, she seems to have much higher girl power than Elinora sister.

''...What?　What's that look on your face as you say it?

It's nothing.

'You may say so with your mouth, but your face is complaining. If you have something to say, say it.

　Was it time my face was complaining? I feel like I'm getting another new variation of the word.

'Luna-san is more girlie - I thought you were more careful with your appearance.

Well, you know, girl power. I'm so sick of my mother nagging me about it these days.

　When I blurted out, Elinora sister looked fed up.

　It's true that you've been getting a lot of attention from Mother Erna lately.

　But that's probably due to the fact that Elinora's sister is so low on girl power. If it's that low, Erna-mother will be worried and want to pay attention.

''Well that's because Elinora has good material. It would be a shame not to polish the beautiful ones. As I thought during the King's Capital exercise, Elinora is too indifferent to anything other than polishing herself with her sword. Why don't you take a look at the shop, whether it's a necklace or a bracelet?

Lady Elinora, let's go!

Okay, I'm not interested.

　Mr. Luna and Meena invited her to join them, but Sister Elinora said once and for all.

　Then she walked away and started to look for shells by herself.

　Elinora is really indifferent to things that don't interest her," she said. You can't force her to do anything.
Ugh.

　Understanding this, Meena and Luna continued their search for shells, looking a little disappointed.

''Hm?　What is this?

　I pulled myself together and continued my search for the shell, and I saw a square object with rounded corners. It was slightly cloudy in color and not crystal clear.

　Could it be the beach glass I often saw on the beach in my past life?　

'Wow!　That's so beautiful too!　What is it?

　As Meena and I are tilting our heads, Eric, who was nearby, comes up to us.

'Ah, that's a piece of magic stone. The magic stone inside the demon's body was washed into the sea and scraped off by the waves. It is not possible to use it as a magic tool because most of the magic power has already been drained out, but it can be used as an ornament because of its beautiful appearance.

　I see, so it's the same as beach glass, although the ingredients are different.

　Shells are good, but these are also quite beautiful.

　I let the sun shine through it and looked at it until I was satisfied with it, then tucked it into my pants pocket.
