win-win

In the one-sided chase through the jungle, Luna kept her eyes glued to the scene, not using any powerful techniques to retaliate. As she watched, she realized Kokushibo's shirt was becoming increasingly obtrusive. Since her eyes were Sharingan, not Byakugan, she couldn't clearly see the movements of his muscles and lungs. Furthermore, her swordsmanship was rudimentary, and she couldn't execute Moon Breathing as a simulated technique.

How can you clearly see muscles?

Let him take off his clothes first.

Luna pulled a steel wire and made a knot in front of it. Kokushibo saw it clearly, but he didn't expect a shadow to suddenly appear beside him, with several talismans pasted on his chest and back.

Thud! Thud!

Several explosions sent Kokushibo crashing to the ground, coughing up blood, his demon fangs becoming even more prominent. This little girl claims she's not an Onmyoji, yet she can exorcise ghosts with talismans!

"Cough cough! It's no use, you can't kill me in one go!" Kokushibo tore off his upper body clothes, revealing the muscles that had been injured by the explosion, which had already recovered in the blink of an eye.

"That's right, that's right, you're amazing!" Luna admired his near-perfect muscle definition, nodding her head repeatedly.

A faint smile of appreciation played on the girl's lips, leaving Kokushibo momentarily silent. Was his thinking so outdated that he couldn't understand the girl's language? Why was she reacting this way when he was clearly mocking her?

"Huh? What's wrong? Can't swing the sword anymore?" Luna was a little confused. If her clothes are gone, she should hurry up and swing the sword. She still needs to review the muscle application.

Thinking that since her opponent wasn't attacking, she would force a fight. Another magic circle flashed, forcing Kokushibo to retaliate. Fighting him like this was no match for Kokushibo; unless she unleashed her ultimate technique with Susanoo, she could only resort to genjutsu. She'd give him a Yoriichi combo then, but whether he exploded or went into a special form, the risk was too high.

Let's learn Moon Breathing first, it's really cool!

Kokushibo's blade lengthened, extending his attack range as he swung it, and he dashed towards Luna in a flash. But Luna, like a rabbit being chased, hopped and skipped away in a web of moonlight and death. Her beautiful figure flickered between the shadows of the dense forest and the bright moonlight.

Has she reached the highest realm?

Looking at the internal organs and muscles, it's nowhere near that level.

Are those eyes really that powerful?

Luna used mental suggestion to induce Kokushibo to practice the Moon Breathing technique over and over again until he had seen all the forms. Only then did she slightly smirk and prepare to test the Sharingan.

She couldn't use anything too outrageous, lest she scare the Demon King behind her to death and cause the Demon Slayer Corps to miss their chance to kill him. She was a Fairy Tail magician; it was okay for her to be a little reckless, but she absolutely couldn't do something so despicable.

"Upwards!"

A roar shattered the tense atmosphere, and the air fell silent for a moment. Kokushibo glanced at the raging wind, tilted his head slightly, and then retaliated with an attack.

The crescent moon and the howling wind intertwined, creating a clanging symphony. Luna glanced at the boy with short white hair, multiple scars on his face, and an incredibly fierce expression, then grabbed a twig and flung it at his hand.

The Wind Pillar, Sanemi Shinazugawa, turned pale, but the next second he saw the small crescent moon hidden in the crescent moon, brushing against his sleeve. He immediately realized that the other party had saved his finger.

He swiftly dodged and continued his attack forward. The Breath of Wind swept down like a dragon whirlwind, but then a large crescent moon flew towards him from below, narrowly missing his heart.

Clang!

Luna's broken sword met Kokushibo's blade, deflecting the attack.

[Opportunity!] Kokushibo's eyes sharpened, and he quickly reached out and grabbed the broken sword, slashing it at Luna's body.

"Hey, your opponent is right here!" Shinazugawa was furious. What did it mean that his opponent completely ignored his all-out attack?

Pfft!

Luna was cut in half.

"Hey!" Shinazugawa's pupils contracted, and he accelerated his attack, thrusting forward.

Another "plop" sound!

Kokushibo was left with a cut on his back. Blood splattered for two seconds, and then the wound was clean and fresh again.

"You can't escape!" Kokushibo glanced at the mud on the ground, then swung his sword at the tree, successfully forcing the person hiding behind it to come out.

"Oh dear, don't get so worked up. How old are you, you little devil? Calm down, calm down. If you keep chasing me like this, I won't be able to use my magic. What? Don't you want to see what I'm capable of?" Luna chuckled, standing on another tree with her broken sword on her shoulder.

"Heh, if that's what you expect!" Kokushibo sneered. It had been years since anyone had provoked him like this.

Immortal River: "..."

Wait a minute?

Magic? What the heck?

"Rising Flame!" Luna snapped her fingers, and a magic circle appeared in her eyes, causing high-temperature flames to rise from the ground around the Black Shibo!

She does know fire magic, but it's not very powerful; at most, she'd just lose a house. Therefore, the only option is to use dreams to create a realistic illusion!

The intense heat made Shinazugawa step back, revealing the ever-rising orange flames. He suddenly remembered that in foreign lands there were beings with special abilities called magicians. Just like the Onmyoji (yin-yang masters) of ancient China, they used extraordinary powers.

A scream echoed from within the scorching heat. The illusion's flames primarily affected the mind, and he was indeed in excruciating pain. But pride and self-respect wouldn't allow him to back down; the ruthlessness in his eyes was directed not only at his enemy but also at himself. He swung his excessively long, grotesque blade, enduring the intense pain, and unleashed a devastating strike from the sky.

"Breathing of the Moon - Sixteenth Form - Moonlight - Lonely Moon!"

With a swing of his sword, the Void God unleashed a barrage of lightning-fast slashes from the sky, each imbued with the Crescent Moon Breathing technique, aimed at Luna and Shinazugawa.

A powerful meteorite struck, and Luna dodged it by grabbing Shinazugawa by the back of his collar. She glanced at the fierce-looking man beside her and said, "Go ahead and slash with all your might. I'll stop him from hurting you. It's risky. Shall we go?"

This person should have gained more combat experience; perhaps things wouldn't have turned out so badly.

"Of course!" Shinazugawa's smile was vicious. The kid beside him, aside from anything else, was fast and had good eyesight, making him a good helper.

Besides, he would still go even if no one helped him.

Luna stood smiling in the support position, no longer using illusion magic, maintaining her persona as a mage. To use magic, thorough preparation was essential; she needed to let Muzan, the one behind it all, know that she was a mage who needed to 'prepare'.

Once, twice, three times...

Shinazugawa's attacks consistently missed their mark, and he clearly felt the speed difference between himself and Upper Moon. Why was this unfamiliar sorcerer able to keep up? She clearly didn't have particularly strong leg muscles.

Snap!

Shinazugawa slashed at Kokushibo's neck, but the bluish-green blade shattered. Luna dragged him away from Getsuga's range, and as he stared at Kokushibo's unscathed, unyielding neck, he gritted his teeth, wanting to roar in despair, his hand gripping the hilt trembling!

hateful!

What a great opportunity!

"Looks like you can't beat me." Luna wasn't satisfied with the excitement. For a life-or-death battle like this, you have to train like crazy, right?

"Aaaaaah! Let go!" Shinazugawa was furious: Let me and that six-eyed demon die!

Kokushibo retrieved the longsword and, standing under the moonlight, didn't give chase. It seemed Muzan-sama was somewhat interested in having him investigate the matter of magicians.

>>>>

The hotel room had poor sound insulation from the solid wood walls and floors; it was quite noisy when people walked around. The furnishings were simple to the point of being austere; don't expect much from a hotel from the Taisho era. Luna chose this room because it had a full-length mirror, and she repeatedly swung her wooden sword.

The mirror reflected her earnest face, a few strands of hair clinging to her forehead with sweat. The whistling sound of the wooden sword cutting through the air was exceptionally clear in the quiet space. Her movements weren't flashy, just the most basic slashes and parries, but each posture was precise, carrying a calm strength beyond her years. She was constantly adjusting her breathing, striving to synchronize her muscles, breath, and what she saw.

Knock knock knock!

"Lady Luna, the carriage has arrived."

"Buy me a pot of oden to eat on the way."

"Yes!" the person dressed in invisibility clothing quickly replied.

Luna quickly took a shower, dried her hair, and put on a dress. It wasn't unheard of in the ninja world, but she'd have to buy clothes that didn't quite fit Koizumi's character. Now, she had the freedom to dress as she pleased.

Last night, Shinazugawa kept insisting on another battle, so Luna gave him a dream. In the dream, he fought Kokushibo, and must have died countless times before finally calming down his violent temper.

As a magician who has mastered the 'secrets of training,' it's only natural that she would become a guest of honor in the Demon Slayer Corps, right? Helping them with their training naturally can't be for free; she needs to eat too.

Upper Moon One's power served as a wake-up call for the Demon Slayer Corps. They rarely received reports of encounters with him, indicating that anyone who did must have perished. The Demon Slayer Corps' leader, Ubuyashiki, readily approved funding and land grants, allowing the Class A and Pillars to participate in the illusionary training.

Luna loved this job and didn't want to refuse it at all, especially since the offer was so generous. Not only did it include room and board, but there was also someone to take care of her, a high salary, and instruction in breathing techniques—the conditions were even more outrageous than those of a telecom fraudster.

As expected of Ubuyashiki, they are outrageously extravagant.

The carriage arrived at a remote mansion with a plaque that read "[Illusion Pavilion]". Stepping out, she saw three guests: a tall, blind man; a petite girl with a butterfly hair ornament; and a woman with a blank expression wearing a two-tone half-length robe. They had agreed to use the pupil technique a maximum of three times a week, and these three were waiting so early—they seemed quite impatient.

After exchanging a few pleasantries and introducing themselves, Luna, knowing that all three were busy, got straight to the point: "Let me make it clear first, this gentleman cannot experience Dreamweaver."

"Why?" It was Shinobu Kocho who spoke, her tone rising with curiosity. She wondered if Shinazugawa-sensei had already obtained it once, so he couldn't use it anymore?

"I have two kinds of illusions, one is through the eyes, and the other is through mental power."

"Is the technique through the eyes stronger?" Himejima Gyomei had heard of it. Shinazugawa stared directly into those eyes and entered the illusion.

Luna explained that this is a difference in experience. The visual experience is more realistic and adjusts itself according to changes in the scene, which slightly manipulates the timeline. The second method requires setting up a space, the flow of time is the same, but the content is relatively rigid.

"I'm not ready yet, so I can't experience either of them today." She certainly wouldn't give the Stone Pillar a dream directly; what if it damaged his brain?

Beimingyu almost burst into tears, but before he could begin chanting, the two people on either side of him suddenly collapsed. He instinctively reached out and caught them both.

It was finished just now?

How sudden! How amazing!

"Well then, I'll get ready. Welcome back tomorrow."

"...Ah." What could he say? A sigh... thank goodness they weren't enemies?
