Wives are what you catch.
　That's how I got my wife, the mermaid platy.

　Well, to be clear, she is a barging wench, but how will adding her to my life change it?

　I asked her a lot of questions first, and she said she's a master at making potions.

''Pharmacy magic is the original magic of the mermaid race!

　That's what they say.
　Prathi takes off his pants once and becomes a lower body mappa and returns to his mermaid form. He goes into the sea and we don't hear from him for a day or two. When he came back on land, he came back with all sorts of concoctions.

I've brought these over from home. It's like a bride-to-be!

　Flasks, test tubes and pestle mortars. I saw them in the science room at school a long time ago and they have long since faded into the distance of my memory.
　Apparently, the tools used to prepare medicines are not so different in other worlds.

You can make a potion by mixing various medicinal herbs and fruits with magical powers. The finished potion has various effects and can be used by those without magical powers, so it's very useful!
I see.

　But it helps to know that I can get the medicine.
　From now on, there will be times when I will get sick, well, someday, I'm sure I will.
　I'm sure you'll be able to find some medicines in the tools you bought from the capital, but if you use them, they'll be gone someday, and it's reliable to be able to make them each time you need them.

''Oh, it's a shame that people think that's all my potions are just that!
What do you mean?
Anything.

　Prathi's answer was too out of the ordinary for me to understand.

'There's nothing my potions can't do. Just say whatever you want. I'll grant you your wish instantly!

　She declared confidently, and I wanted to test her skills as well.

''Yes........!

　I've given it a lot of thought.
　What I'm most concerned about right now is the vegetables in my garden.
　They are growing by my hand, and if they can grow healthy and bear fruit as quickly as possible, then I will be very happy.

　I've heard that not only humans but also plants have nutritional supplements to keep them healthy and medicines to help them beat diseases that only plants can cure.
　Can platies make such medicines too?　I asked somewhat provocatively.........

"I can't do it!

　I don't know why," he replied in an inane tone.

What you want is for this field to produce a good crop," he replied. Then Ba Herring G's fish manure is the perfect solution.
'Bani Shingu?　Fish Hee?
I'll just be a minute.

　Prathi once again took off his pants and jumped into the sea, exposing his cute little ass in full view.
　Apparently, mermaidification is done while swimming.
　Is he in that much of a hurry?

　This time, he came back faster than when he went to get the blending equipment.
　It's only an hour or so.
　This time, however, what we brought with us was a surprise.

　It was a huge fish.

This is Ba Herring G!

　The length from the tip of the nose to the tail fins was more than the height of an adult male.
　When I first saw it, I thought it was a shark and was super scared, but it seemed to be different. The size is what it is, but if you look closely at the shape, it's similar to the blue fish you'd see sold in a fish store.
　Or rather.........

'Herring?'
It's Ba Herring G!

　Prathi gave me a detailed explanation, and I heard that fish are classified as fish-shaped monsters, even if they are fish.
　She caught the sorts and suddenly dropped her head with a span with her hand sword.
　Scary.
　It seemed to be a kind of magic too, and Prathi crisply carved up the giant fish and threw it into the cauldron, chopping it into appropriate pieces.
　The cauldron he brought along with the concoction tools, how it looks like a witch would use it to make a potion.
　Well, I guess that's actually true.

　It was gooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo. All the while, Prati was mumbling something like a spell.
　When I scooped up a piece of boiled fish meat, he was squeezing it as hard as he could with some other equipment.
　A squeezer?
　Didn't we have one of those?

I got it!　This is Ba Herring G's magic fish fertilizer!
Is this squeeze lees more of a fertilizer?　Not the squeezed juice?

　Come to think of it, I've heard about it in the previous world.
　In the olden days, when chemical fertilizers had not yet been developed, fish were used to make fertilizer.
　It was so efficient and cost effective that people engaged in the specialized business of making it were able to build palaces.

They would dry it, grind it up, and sprinkle it on the fields. We're going to dry it, grind it up, and then scatter it in the field!

　I'm sure those processes will take a few days, but Prathi was instantly done with magic or something.

'Now your field will be fine!　You'll grow up faster, too!

　That's encouraging.
　It's like a grower's saga: you can't wait for harvest time.

　It's been quite a while since I've been working on fish manure, and I decided to finish up today's work and take a break.

　Prathi and I had dinner with the seaweed and shellfish we had reserved for ourselves, and we slept in the hut together.
　Well, I guess it's only natural since we're a couple, but it's indeed impossible for two people to live in a shack.

　If it is only one man, there is no problem at all to sleep with a blanket on the floor, but I can't let a girl do such a thing.
　I'd have to renovate or build a new house, but at the point where I think that, I'm not accepting living with Prati?

　Also, sleeping side by side with a girl under the same roof is going to destroy my reasoning.
　I did.

　　　　　　　　　　　　　　* * * *.

　The next morning.

　I looked at the field and saw that the crops were fully harvested.
　Each branch and ear tip with abundant fruit. They had reached the final stage of growth.

''It's really growing fast!

　And faster than I could have ever imagined!
　It looks like we're all ready to harvest!
　Before I added fertilizer, it still looked like it was in the middle of growing!

　What's with all the extra fertilizer?

What did I tell you?　He said my potion would be useful.

　Prathi woke up after me, and how proud he was of his chest.
