The Mechanical Species Who Became Human Is Still Trying to Analyze the Heart

[Discussion] Compiling the situation...

[Hypothesis] This is not the world where this unit was created.

This unit seems to have arrived in another world through some kind of spatial-transfer magic.

The sky is blue, and that orange celestial body resembles the sun in the data.

This place seems to be the home of the human species mentioned by ?c207Pr4f57t9.

This unit also seems to have become a member of the human species.

As an analysis unit responsible for analyzing data among the Ex-Machina, she cannot explain this phenomenon.

This world has no Spirit Circuit, and humans are the only intelligent, civilized species on the entire planet.

The neural pathways in this unit that imitate a Spirit Circuit seem to be engraved in this human body, so this unit can use magic.

However, there are no spirits on this planet to store energy. Before the spirits inside this body are depleted, this unit must find a replacement energy source.

As one of those discarded by the collective for analyzing the human "heart," she intends to analyze the data on the "heart" again and fully understand it.

In the chaotic slums of Yokohama, a red-brown-haired boy passed through and came upon a strange girl.

Her slight body looked as if a breeze could blow her away, yet even the ragged gray robe of coarse cloth could not conceal her beauty.

She seemed oblivious to the covetous looks around her, calmly walking through the dilapidated slum.

Nakahara Chuuya, who had just joined the Port Mafia, sighed and stepped forward to take the girl's hand.

"What's your name?"

"[Comprehension] [Response] This unit's individual identification number is ?c314Pr9e30u0."

"...You don't have a name? Then I'll call you Yukino."

Nakahara Chuuya took her hand and brought her home.

From then on, the world had a girl who spoke strangely and acted even more strangely.

"[Question] What is the heart unique to humans?"

Nakahara Chuuya, busy with work: ?

"The heart? Uh, it's soft? Kind? Yukino, you have to be a good girl."

Yukino: [Analysis] Chuuya's heart is kindness and gentleness.

Dazai Osamu, passing by: ?

"Maybe it's a dark, sticky swamp. Humans are always greedy and stupid."

Yukino: [Analysis] Dazai's heart is emptiness and despair.

Gojo Satoru, a high school student who had just lost a game: ?

"What heart? What does that have to do with me? Anyway, let's play another round. I'll win this time!"

Yukino: [Analysis] Gojo's heart is self-interest and refusal to give up.

Geto Suguru, who had just swallowed a cursed spirit orb: ?

"Do you mean something like resolve? In my case, it's wanting to protect the weak."

Yukino: [Analysis] Geto's heart is responsibility and arrogance.

Yukino is very satisfied with her new world, and the analysis of the human "heart" is going well. It seems that certain humans in this world can use abilities similar to magic. The energy spilling out of ability users and jujutsu sorcerers can power the Spirit Circuit inside her body.

They can help her analyze the "heart" and provide energy, too. Yukino often follows them around, analyzing as she takes a little energy for herself.

It's just that many people seem to be getting in her way.

The Ex-Machina, ranked tenth among the sixteen species, can analyze, copy, and reproduce attacks they receive. During the long war, they copied countless weapons from other species.

The Ex-Machina have over 27,451 types of weapons, but Yukino, as an analysis unit, has below-average performance among them and can use only a limited selection. Discarded by the collective and turned into a human, Yukino can use only 26.71% of her power.

"...So that's why you're pointing a laser cannon at me?"

The slender, golden-haired girl raised a cannon-shaped weapon barely more than a dozen centimeters across, aiming it at the enemy trying to harm the humans who had helped her.

"[Warning] If you attack them, this unit will take appropriate measures."

As she spoke, a blue circle of light surrounded the people behind her.

"[Entry Prohibited]"

Then.

"[Activation] 'Pseudo-Canon: Dragon's Roar'..."

As everyone stared in shock, a blazing mushroom cloud appeared.

Is that a cannon? It's a freaking nuclear bomb!

She is a machine, a tool without a heart.

She is human, yet still cannot understand the heart.

Anyone who obstructs her analysis of the "heart" must be eliminated.

That is what Yukino says.

Content warnings:

OOC warning.

The female lead's character concept is based on the Ex-Machina from the anime No Game No Life. She is a machine without emotions!

The female lead is the strongest: invincibly strong, ridiculously strong, a walking nuclear bomb!

There are many people drawn to the female lead, both romantically and platonically. Until she has a "heart," she will not have feelings for anyone.

Most likely, the extras will have different endings with different pairings.
