The season was summer and classes in the pool were starting at Hartley High School. The country of water was climatically cooler than the kingdom with the Morot and was about as comfortable as it was used for resorts.

"The pool class starts today, but good luck with the pool class as it will be considerably tougher than other subjects. When you're in class, please put on the gear that's in the dressing room and gather at the pool yard.

"" Gear?

What's gear, not swimsuits?

"Dr. Milva! What is equipment?

"Is that it? Didn't I tell everyone? This school pool class basically swims with underwater gear on top of the swimsuit, right?

"No, that's my first ear!

"It's okay, it's okay, because you only have 5km of first-year gear in total. It's normal if you get used to it.

(Are you feeling weird...? Swimming with 5 kilos is pretty tough...

The gear available in the dressing room weighed one kilogram at a time, four for both hands and feet and a total of five belts to attach to the waist.

Wouldn't there be an accident by letting him swim weighing 5 kg at the age of 10......?

Everyone gathers in the pool wearing gear as they were told, even though they are anxious to see if they have the same idea.

"Yes. You've all been well equipped. On the first day, you just walk without swimming and get used to the weight of your gear. In the third grade, you put on 10 kg of weight while wearing clothes and have a water competition.

"" Uh-huh! "

"I'm not complaining ~. Please give up because this is a mandatory task in high schools in this country.

In the end, everyone was walking about 0.5 km underwater struggling, and some students were gibbering up along the way.

I was a natural give-up group. You still seem to have low physical abilities.

Basically, I'm good at brain and hand dexterity, so I was wondering if I could use that to cover my low physical abilities...

In the future, we want to create [Magic Coating Armor] that has been powered by [Magic Coating Clothing]. [Magic Armor] Simply put, it's like a power suit or a robot. I prototyped a few of them, but for now I'd have performed better in [Magic Coat].

The powersuit type made by diverting the skeleton used for the [Magic Doll] was difficult to operate and could only be moved easily.

Thanks to the [ultra-fast processing crystal] that I have in my brain myself, the arithmetic speed is going up beyond the constant, but I don't get the arithmetic speed like Mr. Cecilia.

I don't think I can manipulate such fine movements at the same time with a good [Magic Doll].

But there are measures to improve, but it was risky. I've also created a [crystal] equivalent of the memory I say on my computer, but I need an advanced healing magician like your mother to mess with my brain, and your mother won't do it first.

So, the next thing I thought about was mounting the computation device externally, and thinking about a robotic type with an external mechanism that boosts my computation speed.

This has yielded some results, good maneuverability and performance, but it was too huge to be about 4 meters long, and limited availability and poor fuel consumption.

Future improvements were going to be robotic compact, dedicated armed development and fuel efficiency improvement.

"Ray-kun is thinking bad things again.

Karin, who is finishing an underwater training in the name of pool class at the top, spoke to me.

"How rude that it's a bad thing... I've been thinking about how to strengthen myself.

"Ray-kun may not have noticed, but when you're thinking bad things, you're smiling weird, aren't you?

"What? Are you in my face?

"Ray-kun has quite a few emotions on his face.
