Regarding the fact that my best friend is a magical girl

They finally came up with a powerful active move, but it caused trouble the first time they used it, and the monster they were targeting escaped.

This was a severe blow to her mental state; her hard-won fighting spirit was about to be extinguished...

That won't do.

"No, whether it's a monster or a wildfire, Seruno has to handle it!"

The person speaking was Yang Yan; she was even scolding me.

“Miss Miluno, you are a bodyguard, not a nanny. Your only responsibility is to ensure her safety. You have no obligation to clean up her messes.”

It would be easy for me to deal with that stupid tree stump; I could kick it into a pile of firewood with almost one kick. But if I did that, I would also cut off Seruno's chance to make amends, and this matter would continue to trouble him.

In the end, it was Kagerou who thought more about Seruno.

"I understand. Leave the strange man and the wildfire to Seruno."

"...I...I'll try my best."

"Not 'try your best,' but 'as soon as possible!' The association has already contacted the fire department. Once the strange creature is dealt with, the fire brigade will come up the mountain to put out the fire. So the sooner you can deal with the tree stump monster, the sooner you can control the fire!"

Despite being paralyzed in bed and unable to move, Kagerou was in high spirits and was quite demanding of Seruno... truly a commander of the fountain.

But she is definitely more suitable than me.

"The tracking drone was knocked down by a branch... We can't find the strange man anymore."

Seruno quickly became at a loss.

That strange-looking man, who resembled a tree stump, was none other than a Viet Cong member in disguise in this mountain forest. Once the target was lost, finding him was no easy task.

"I've never seen such a cowardly weirdo who would actually try to survive."

Yang Yan cursed and said, "It's stalling for time to let the wildfire spread. It knows we can't just leave it unattended... Watch out, the powerful sound of thunder is coming!"

From this vantage point on the hillside, you can see the park entrance.

A magical girl wearing sunglasses, riding a black motorcycle, but dressed in a light blue and white dress, barged in. Her short hair was also light blue.

However, she was clearly more suited to wearing the kind of bajaka that read "noisy and superior".

She looked up at the wildfire, then pulled out her weapon from behind her back.

A uniquely designed loudspeaker.

"Setting the mountain on fire! You'll be locked up for life!"

The sound was very loud; it could be heard clearly even from this distance, truly living up to its name of a powerful and resounding sound.

"What is this person's popular nickname?" I asked.

“Loudspeaker,” Yang Yan replied.

"...I was wondering if it could be this."

Compared to Metal, the "Steel Dragon" who is quite famous in the D4 area, this "loudmouth" didn't really leave any impression on me.

I jumped down from the tree and walked down the mountain path.

"...I...I found it!"

But good news came from Seruno, who was standing on the mountaintop.

"There's no wind today, but the trees over there are moving!"

Kagerou reminded Seruno over the walkie-talkie.

"Wait, you can only see the strange man's movements clearly if you stand on the mountaintop. If you just keep running like this, you'll easily lose your way."

Seruno created another bubble beacon in the air, while Kagerou also asked the association to send a drone to keep watch from high altitude.

As for me, I had already run to the thunderous roar at the mountain pass.

"Oh! Miluno! I know you!"

Despite her clean and delicate magical girl appearance, she completely fell apart the moment she opened her mouth.

Do you have a way to control wildfires?

"My magic can extinguish fires."

She patted her megaphone.

"Use your voice."

Extinguishing a fire with sound is unusual, but I had no choice but to try anything, so I picked her up from behind.

"Hey? Wait a minute, girl! What are you doing all of a sudden?"

"I'll take you up the mountain!"

We've made a huge mistake.

The sunlight gathered by this convex lens, hundreds of meters long, was far more powerful than I had imagined. It left a scorched path of destruction in its wake, and even sparks flew from trees that were not directly exposed to the light.

This solar beam must be thousands of degrees.

It possesses overwhelming power, but it is extremely difficult to control. Even the slightest adjustment to the convex lens bubble can leave a fire trail tens of meters long on the ground. Not to mention, the brightness is so intense that even I cannot open my eyes. Under such circumstances, it is almost impossible to accurately hit a running target.

"Serno! That thing realizes it's been discovered...it's going to run away again!"

"Why would they send such a cowardly weirdo?"

Two old trees bent their trunks and swept their branches across the ground.

Then I stopped blocking the road, unable to get through, and had to go around the two old trees that were almost lying horizontally.

The old tree remaining still is a signal that the strange tree stump has been uprooted. As soon as the strange tree starts moving, the new drone will be able to detect its movements.

"It's determined to stall for time; it's right ahead!"

"I saw!"

With its clumsy, root-like legs, the strange tree stump struggled to escape before me, but now that it was in my sight, I naturally had a way to stop its movements.

"what!"

The stump monster was enveloped by my bubble and floated into the air due to the expansion reaction force.

The roots and branches lashed against the inner walls of the bubble, making a crackling sound, but I "refused" to let it go. As long as my magic remained, that seemingly fragile bubble was like an impenetrable iron wall to it.

"This time, I won't let you escape again."

The blinding rays of sunlight pierced through the tree canopy and shone precisely on the bubble. The exaggerated heat was unbearable even from more than ten meters away, making it difficult to breathe. The twisted trees around them began to catch fire, turning the ground into a scorched wasteland.

As for that strange man on the tree stump...

Uh, he's turned into a charcoal ash monster.

(Sun Yao)

"Oh! Yeah!"

I took care of the weirdo all by myself!

Although that tree stump was considered a particularly insignificant character among the oddballs.

"Don't be complacent! Now that we've dealt with the weirdo, the next step is to put out the fire!"

Urged on by Ms. Kagerou, I realized that I was surrounded by flames. Although I could escape by wrapping myself in bubbles, I had no idea how to put out the fire.

The fire is huge!

Looking back, half the mountain was ablaze. The nearest water source was Changyue Lake at the foot of the mountain. What am I going to do...?

"A thunderous roar! To the left!"

Miss Miluno's shouts.

boom--

The dull, low-frequency sound waves bombarded my eardrums, while the flames in front of me were unwillingly extinguished in the sound waves, turning into wisps of black smoke.

"Hmm, I keep hearing a water sound in my ears..."

It's gurgling and flowing; I've gone deaf.

Yangyan seemed to say something, but even though I was wearing a walkie-talkie, I still experienced temporary hearing loss.

"Huh? What did you say?"

"I'm telling you! This is a fire extinguishing technique that uses sound resonance! It uses sound waves of a specific frequency to reduce the oxygen density in the air, causing the flames to lose their conditions for combustion. But generally, it requires very high power; it really is something that can only be achieved with powerful sound waves!" Yang Yan said, almost shouting.

I thought putting out a fire with my voice was some kind of magic, but is it really possible?

"...It's very powerful, but it's a bit noisy."

I picked at my ears and found that my whole body was numb from the vibration.

Miss Miluno was seen carrying the blue magical girl and running through the forest with a megaphone to put out the fire. However, it was the middle of the day, and with the surrounding area still burning, the temperature was ridiculously high. The fire they had extinguished would soon reignite.

I asked, "Doesn't the tactical officer have any firefighting plans?"

"The firefighting drones have already been mobilized. If I were here, I would use fire phosphorus to deplete the oxygen first... Ah! Seruno, I've thought of a way for you to put out the fire too."

"what?"

"Can your air membrane expand and then contract again?"

"can."

"When air is compressed over a large area and then suddenly released, it will create a strong wind. The wind can carry away heat and also deprive the necessary conditions for combustion."

At such a high temperature, it might not be effective.

But we still need to give it a try.

The convex lens bubble above their heads began to compress and fall.

Even when compressed to its limit, air remains gaseous. To compress it further into a liquefied state, in addition to immense compressive force, extremely low temperature is required, which I cannot currently achieve.
