A calm perspective resides within my body, which has become burning hot with embarrassment. The power of the Cobalt Princess seems to make it easier to maintain a balance between reason and emotion.

Right now, the most important thing to do is clear: rescue Tenuto. Nothing else matters.

The fearsome magic "Aria of Extinction" unleashed by Assassin Rabbit. As the name suggests, it's a technique to "erase Tenuto from this world." If he's thrown into a subspace like a black hole and left unable to breathe, he might truly disappear as time passes.

If that's the case, what must be done is to call him back immediately, without delay. But how?

I had one idea. What if there is an inversion magic for "Aria of Extinction"?

Yes. In this world of musical magic, there is the concept of inversion magic. The inversion magic of the basic fire spell, which is an elementary flame magic I cast earlier, is the basic ice spell that the enemy cast—the basic ice spell of the elementary ice and snow magic. The principle is simple: by replacing the major scale-based Basic Fire with a minor scale, it becomes the opposite effect, Basic Ice. The more advanced the magic, the more this simple rule of turning major into minor doesn't hold, but for elementary magic, the simpler the replacement, the more cases there are where inversion magic can be created.

What about "Aria of Extinction"? It can be inferred that the melody is relatively simple, but its effect is advanced magic. I have no choice but to take the gamble.

While fighting, I memorized the melody of "Aria of Extinction" by ear and pictured it in my mind. Then, I replaced the minor scale with a major scale in my head. Honestly, I'm doing something quite advanced. Is this the feat the Cobalt Princess can achieve?

I blow into the saxophone. I name it "Aria of Restoration"!

"What are you playing? I have a bad feeling about this! You won't make me!"

She takes up her violin, preparing to unleash a counterattack spell. The bow is aimed at me, surrounded by violent light.

"I won't let you!"

Suddenly, Usamofu leaps from the side and tackles the Assassin Rabbit in her black attire.

Usamofu, while calmly assessing his own abilities, desperately buys time for us.

"I may not have the same magical power I had when adventuring with Akira and the others, but there's still something I can do!"

With Usamofu's shout, he unleashes a basic wind magic spell, Kamaitachi, to disrupt the timing of Assassin Rabbit's violin performance.

He's effectively buying us time.

I focus all my nerves on the saxophone and complete the melody of "Aria of Restoration."

A beautiful melody transformed into a major scale resonates in my ears and gradually materializes as the sound of the saxophone.

"Please! Tenuto, be saved! If you die, I... I..."

The moment I finish blowing the last note, the space trembles violently, and a flickering light dances at the edge of my vision.

A vicious, pitch-black hole opens again. But this time, it's not to swallow but to emit something.

"Cough! Cough!"

Out tumbles Tenuto, gasping for breath.

I rush over and embrace him tightly.

"Tenuto!"

"Ah, I thought I was going to die. I was thrown into a space where I couldn't breathe... Did you save me?"

I nod firmly.

"Thank you."

Hearing those words, I hold him close. Tears naturally spill over. But there's no time to wallow in sentiment.

"Usamofu, thank you for the distraction. From here on, we'll fight together."

"Forte! We did it! Pant pant, well then, I'll take a little rest."

Usamofu says this and sits down a short distance away, then lies down there.
