Regarding the fact that my best friend is a magical girl

ui-31 nodded in response.

I really want to punch it. As Miluno, I have a boost in rationality, yet this makes me so angry. This werewolf is no ordinary creature.

It roared again, "Awoo awoo!"

"It says...it needs a strand of Miss Miluno's hair."

Melissa has completely become a translator.

"Is it perverted?"

Why would he need my hair? Is he the type to stay in the classroom after school and smell the hair of the girl he likes?

"Awooo, awooo."

"It said... give it hair and it will remove this armor."

"No way, who knows what you'll do with my hair—hey!"

It turned out that it picked up a soft, long black hair from the grass. Melissa's hair was fiery red, while Antarctic Star's was not that long.

If the story unfolds correctly, this must be my hair.

But why am I losing my hair?

This is a worrying sign.

ahh-

The ui-31 actually twisted my hair and put it into its mouth like it was eating a pseudo-factor... to be precise, into the mouth of the wolf helmet.

"...Does eating you somehow grant me control over my magic?"

The werewolf stopped howling and instead lowered its head, seemingly contemplating something.

Fearing it might cause any more trouble, Antarctic Star hunched over in a fighting stance, while Melissa remained still, simply standing with her hands on her hips, waiting for something...

"What's wrong with this guy?"

No one answered me, but the werewolf's body changed. The tokusatsu-style mechanical armor transformed into black and red lightning, which quickly converged on the fingernail-sized metal pyramid on its chest.

At this point, the UI-31 finally revealed its true colors... what a load of crap!

It actually turned into what I looked like when I was male.

He's even better in shape than me. He's lean and muscular, but his muscles are clearly defined, and he's bursting with masculine hormones. He's a real man among men. Even though his skin is a bit dark, he doesn't look out of place in Hawaii.

This muscular physique clearly doesn't belong to me; it seems he can only change his appearance.

He was wearing a pair of yellow floral beach shorts with his rather fit upper body bare, but he quickly changed into a white tank top. It was the kind of old man's style, but he managed to make it look cool.

I lost, and although I'm pretty handsome, I still feel resentful.

Moreover, the ability to trace my original appearance through my hair greatly increases the risk of my identity being exposed. Although Sirius can also sense the Star Crystal, she disagrees with Spica's political views, so she agreed to keep it a secret for me. However, UI-31 is an unstable factor.

"Awoo~?"

But he still couldn't speak.

Melissa translated, "It said... he thought he would become like you."

That looks so bizarre, a lightweight bodybuilder Barbie?

"Eating hair can transform you into someone else? Unfortunately, that hair isn't mine. It's the hair of Seruno's friend. He probably dropped it when he passed by... right, Miss Melissa?"

I asked Melissa for help.

As the head maid of Sirius, she knew my identity and understood the meaning behind my words, so she also began to cover for me.

"Yes, before we set off today, I took Mr. Bai Ziye for a walk around this area. It was probably a hair that fell out at that time."

When she said that, I breathed a sigh of relief.

But ui-31 seemed not to understand; he tilted his head with my face in a way that looked really irritating.

I wasn't going to give him time to think, and pressed on: "So, what exactly is this mimicry-like ability of yours?"

"Ow—"

He took out a notebook from his pocket and presented it respectfully.

Melissa: "She hopes you can take a look."

I looked at Antarctic Star and took the notebook from him.

The cover of the journal says "Diary," and the characters are fairly neat. Luckily, it's Chinese characters; it would have been troublesome if it were some other language.

I am a human being.

The first page contained only these three words, as if to remind me, and they were intentionally written in large characters. I looked up at ui-31, and a few complicated thoughts arose in my heart.

You said...you are human?

It gestured for me to continue reading, and then reached out to stroke the Golden Ship's head.

The second page records his "model number".

He is a prototype of an infiltration weapon created using "humans" as the material.

Infiltration weapons, as the name suggests, require special units that can infiltrate human society and wait for an opportunity to strike. Therefore, they are designed to transform into humans they can eat in order to replace the social identity of the other party.

Because it was a prototype made without regard to cost, its combat ability far surpassed that of ordinary monsters, reaching the level of a witch.

However, something went wrong during the transformation process, and the most crucial brainwashing step failed. He then pretended to have been brainwashed and was thrown into the wormhole along with the "tree stump".

"You're really something else, aren't you?"

That concludes the self-introduction; what follows is the actual diary entry.

[When I tried to steal the simulated factor, I was attacked by several magical girls. The one with long black hair was very strong. Fortunately, her old injuries hadn't healed, otherwise I wouldn't have been able to escape.]

Although her legs are beautiful, tulle under her short skirt is still too much; I really hope she can remove it.

I stomped my foot.

I stepped on that familiar face.

Chapter Thirty: This is a misunderstanding

(Albinocotyledon)

[Ability Observation Record: The absorbed pseudo-factors can be manifested under their own control...]

I successfully sneaked into the cargo hold of the passenger plane, but not the unpressurized compartment. It was cold, dark, and severely oxygen-deficient. This flight would take more than ten hours, and I really didn't want to go to Hawaii in such an inhumane way, but time was of the essence, and I had to protect that important princess.

Ah, so he was hiding in the cargo hold of our flight...

Antarctic Star pointed to the diary and asked, "Who is the princess you wrote about here?"

ui-31 thought for a moment, pointed to the beach in the distance, and then squeezed out a silly, goofy smile.

"Serno?"

He then clapped his hands in affirmation.

He knew Seruno well, not just me, and he even imitated that smile quite well.

Information about magical girls is almost publicly available online, so it's not surprising that he knew this. However, from a macro-strategic perspective, this is tantamount to telling all the secrets to "the other side," which will put the magical girls at a disadvantage in their battles.

That's why the situation arises where Yangyan is unilaterally suppressed by "Lava".

As I was pondering this, a white halo appeared in the sky above the beach.

That's the association's wormhole; the interception experiment is about to begin.

Melissa said, "Let's go back to the mansion first and report this to the association."

Since this guy has my (Bai Ziye's) face, I have no objection to this decision.

"Stand up and leave."

"Ow—"

She kicked him, and this time he let out a painful howl. It seems that after removing that stiff werewolf armor, he was nothing more than a weak lump of flesh and blood.

On the way to the mansion, I turned around and asked, "Are there other peculiar people like you... uh, infiltrating weapons?"

He shook his head.

"No?"

He continued to shake his head.

"You don't know?"

He nodded and let out a "whoosh".

Think about it and understand.

He was merely a weapon, a defector, and he had no idea whether any similar weapons had been thrown over by "the other side."

The existence of ui-31 makes the situation both troublesome and urgent. A monster capable of mimicking humans could easily tear apart humanity's current defense mechanisms—fortunately, the prototype means it hasn't been mass-produced yet, so we still have time.

Although I disagree with some of the association's ideas, I must let Spica know about this so that we can develop a solution as soon as possible.

Sirius and most of the maids went to the beach, and some went to "Canis Major" to take care of the dogs, so the mansion was very quiet.

Melissa even stopped the Golden Ship from entering.

Despite their excellent training, Sirius simply wouldn't allow these clever dogs into the mansion, and no one knew why.

"Please have a seat, I'll go contact the association first."

Melissa hurriedly went upstairs, leaving only me, UI-31, and Antarctic Star. Antarctic Star and I could easily subdue the dearmored UI-31, and we weren't worried about him escaping.

If he truly wants to prove he's not an enemy, then he has no reason to run away now; instead, he should earn our trust through his actions.

Of course, trust is not something cheap. I did not accept everything recorded in the diary, nor did I regard him as a companion.

The living room of the mansion was originally the lobby of a hotel, so it is larger than a typical living room. Furnishings from the hotel era, such as a piano and a luggage cart, are placed in the corners.

And the sofa seating area in the rest area.

"sit down."

The ui-31 was obedient and sat down obediently on the sofa. Its posture was decent enough that it didn't embarrass my handsome face.
