This Thing Moves!

“…On! Hey, Leon.” (Conan)

My body was being shaken.

“Ah, hmm. Conan-niisan.” (Leon)

Before me was Nii-san with a look of blood I had never seen before. He seemed to have run from somewhere, breathing heavily.

“What happened!?” (Leon)

“I don’t know, but somehow I feel…” (Conan)

“That’s why I told you to rest!” (Leon)

Whoa, scary.

“Hein too! What were you doing?” (Conan)

“Eh, no. Even when I came back, he was already…” (Hein)

“Niisan, Hein-niisan is not at fault!” (Leon)

“Haaah. Yeah, you’re right. Sorry, I lost my composure.” (Conan)

Then, Conan-niisan turned around and crouched down on the spot.

“Hain. Let me carry Leon on my back! We’re taking him to the Inner Place.” (Conan)

“U-uh, yeah, got it!” (Hein)

Hein-niisan lowered his eyebrows, wrapped his arms around my back from the side, helped me stand up, and then let Conan-niisan carry me on his back.

“Let’s go.” (Conan)

That voice sounded distant.

“Leon. You have woken up, haven’t you?” (Mother)

“Yes. Kaa-sama.” (Leon)

A soft, cold finger strokes my forehead as I lie in bed.

“Was Conan-niisan still angry?” (Leon)

I did something bad to my brothers. I have to apologize later.

“He is not angry. Both Conan and Hein are very worried about you.” (Mother)

“I see…” (Leon)

“Conan is not just a brother. He will soon become an adult and eventually inherit the Liones Trading Company. You must listen properly to what he says.” (Mother)

I nodded.

Conan-niisan will become an adult soon. When spring comes, he will turn 15 and be recognized as an adult.

“Today, you should stay in bed. I will have dinner brought to this room.” (Mother)

“Okay.” (Leon)

“Well then.” (Mother)

Kaa-sama smiled gently, adjusted the blanket over me, and left the room.

Sorry. I can’t stay obedient.

I sat up and took one of the two sheets of parchment on the table. I saw a round activation symbol, but as I moved my gaze to the pull-down menu and slid down, the shapes changed one after another. Among the unknown characters on the menu, I selected the only one I recognized, Earth.
Then, the display switched to a nostalgic block diagram. A block diagram was a figure made of blocks that described the path where signals traveled and the transfer function of how those signals changed.

Until yesterday, I didn’t know about this diagram at all, but now I do. Since it was in the memories of a person named Toudou Reo. I feel nostalgic because of his memories. Why do I have his memories? Before, Morgan-sensei said there is a belief in foreign countries called reincarnation, where a person is reborn into another after death.

Then, could the dreams I have been seeing until now be actual events? Toudou Reo died, and was reborn as Leon. In other words, he reincarnated, I think. No, since I can recall it so vividly as if it were my own memory, it must be true.

I took a deep breath to calm my racing heart.

But why did memories from a past life resurface? I have never heard such a story. But probably because of that. My desire to control has grown greatly. I have an uncontrollable impulse to try various things, so I look at the parchment again. Though I look at it, it is not an activation symbool drawn with ink, but an extended block diagram.

Simply put, the blocks were parts that changed signals, and by connecting them with arrows, branch points, and junction points, the diagram expressed various phenomena as flows of signals. Returning the downstream signal to the upstream and looping the difference was the classic feedback control.

This example added three blocks, with extended parts for step input and a scope symbol to see the waveform. There was a scope display on the right. So, it was not a pure block diagram and should properly have been called a SimuConnect model. But apparently, either was fine.

It is the SYSLAB_Simuconnect I used in my past life, commonly called SysLab SimuCon.
Version v20XX.7.321, huh.

Amazing. Even though I haven’t used it for over ten years, it feels like I used it yesterday.

The cursor followed my gaze.

Whoa.

When I focused on the right-pointing triangle icon, the icon’s color changed. It was the SimuConnect start button. At that moment, the scope display on the right wavered.

“It moves!” (Leon)

The graph waveform kept rising.

Amazing. It really is moving. Hmm. What happens if it moves? This is magic, isn’t it?!

“Haaah, haaah.” (Leon)

Instinctively, I clicked the stop button.

If the magic actually activates, it’s dangerous.

“How could I…” (Leon)

Me? Anyway. Knowing that it moves is very good. But I have to carefully confirm what happens when it moves because it’s dangerous.

First, let me calm down. Looking again, the title says AQUA with limited functions ver1.29. This must be the water-related assignment from last week. My heartbeat is still fast. When this happens, I calm down by explaining something. To whom? No, I will explain to myself.

SysLab, simply put, is a base environment software for mathematics and engineering. It can be used alone like a function calculator, but it is usually used in combination with some other subset application. One of those somethings is SimuConnect. It runs a signal simulator and control model-based development environment.

Good, I’m calming down a little.

Both of these were the industry (de facto) standards in the earth and era where Reo was. Most people who did robot control used this software. It seems pretty expensive if companies or working adults use it, but students can use the academic version at a subscription price almost free. Of course, at the university, you could use it with an account provided by the school.

“But to think that magical activation symbols can be described with block diagrams.” (Leon)

Speaking of which, Morgan-sensei said that activating magic required going through stages.

“Then, it’s easier to describe with state transition diagrams than block diagrams, right?” (Leon)
The moment my thoughts overlapped clearly with Reo’s, the display instantly switched.

“Whoa. Stetra can be used too.” (Leon)

Hmm. The state transition diagram appeared. The window title changed to SYSLAB_State_transition v20XX.3.11, commonly called Stetra.

Block diagrams made it easy to understand signal flows, but state transition diagrams were easier to describe systems where states changed in a time series. If anything, the latter could be called the higher-level concept.

Hmm. After all, I want to try how it moves. But this is inside my room. What if it gets flooded? Huh, on the contrary, would the magic activate? I was confused earlier, but if I think carefully, when moving a motor with SimuCon, special hardware is necessary. Maybe magic also needs such things?

Right. I’ll ask SysLer, the interactive AI of SysLab!

“SysLer, can magic be activated with SimuConnect?” (Leon)

“Yes. If the Possessor subset that operates the human body is enabled, the environment to activate magic is established. Currently, the Possessor subset is disabled.” (SysLer)

Oh! The familiar female mechanical voice, though in Cecilian language. Possessor. In English, it means ownership… no, it means to become or possess.

“SysLer, can you enable the Possessor subset?” (Leon)

“Yes. Tokens are sufficient. Do you want to enable it?” (SysLer)

Yay! I can use magic. Joy runs up my spine. This is not simply happiness about being able to use it. I’m happy that I might be able to control it. Good, good, good.

“Leon-san, do you want to enable the Possessor subset?” (SysLer)

Oh, I’m tired.

“No. I will not enable it.” (Leon)

“Understood. Please say if you need it.” (SysLer)

That’s right. For now, it’s better that magic does not activate. I will try it somewhere safe.

I see, tokens. They feel nostalgic. Tokens are numerical values that represent the right to enable subsets within the system. Roughly speaking, it’s like money. When enabled, the tokens decrease, and when disabled, they refund. So, it’s limited to how many you have, but you can combine the necessary subsets as needed, and after that, rearrange them. That is tokens.

I wonder how many tokens I have.

“SysLer, show me my account.” (Leon)

“Yes. Displaying Leon-san’s account.” (SysLer)

Oh! A dialog opened.

Registered user: Leon (Toudou Reo) / Soare system, second planet humanity (Humans) registered

Account: Control Authority

Token count: 32,767

Privilege level: Senior system operator (2)

System: Earth version emulation

Civilization base language: Cecilian

There is both my name and Reo’s. This system considers us the same existence. And Soare, if I remember correctly, is the name used when calling the sun a god.

“Control Authority…” (Leon)
