A temple in Sapporo.

Thank you for coming, Kien-sama.
Shit. It's because you are so slow that we have to come all the way out here. I didn't want to come here, d*mn it!

　The one who swears at the welcoming Yin-Yang Master is Kien Gouki, one of the leading Yin-Yang Masters serving the Hinoyama Family.
　He is one of the most skilled Yin-Yang masters serving the Hinoyama family, with the ability to fight against demons single-handedly, and is one of the most powerful Yin-Yang masters in the Hinoyama family.
　It is said that when it comes to annihilation, there is no one who is better than him among all the Yin-Yang Masters.

"Why do we have to come all the way to Hokkaido to look for cats? You, Three Crane Castle, remember that!

　The reason he came to Sapporo is to search for the missing Nekogami.
　His onmyoujutsu, except for combat, is below average, and his specialty is widespread annihilation that can turn an entire area into a vacant lot, so searching for the Cat God in a residential area is clearly not a suitable mission for him. However, Mitsurugi Yuen, who selected him for this mission, had a firm idea.
　To put him in an environment where he can't show his true feelings, so he can work while preventing him from going out of control. And to send the selfish and self-righteous Kaira to blast those who were on the same mission.

　Just as Mitsurujo thought, the Ki Flame, which was unconsciously making the Onmyoujutsu practitioners around it feel impatient, found something strange.

''What is that?''
It's a ... scouting shikigami!

　I looked up at the sky and saw a white crow about to cross the sky above the temple.
　A scouting shikigami. Hearing those words, the Qi Flame looked like a beast that had found its prey and gave instructions to the surrounding Yin-Yang Masters.

''Just as well, set up the wards!
I've never seen this shape before, but it's most likely the shikigami of the Water family surgeons. If we put up a warding, that shikigami's link will be severed, and the surgeon will be alerted to the abnormality.
'It's too late for that! When you're letting the Nekogami get away, it's bound to be suspicious! That ceremonial god is proof of that.

　Pointing at the white crow, the qi flame announced. His words were a good argument, and the convinced Yin-Yang Masters followed the instructions and began to create the wards.

''After the connection is broken, I'll take care of it before it destroys itself. After that, identify the surgeon from the wreckage. Let's go hit them.
All right, all right.

　Allowing a shikigami to infiltrate another faction's temple without permission would be a signal to declare war.
　There was no way they would be able to attack.

''Warding is complete!

　One of the sorcerers shouts out. The transparent wards encircle the temple grounds, enveloping the temple with every white crow.
　The crow is disconnected and hovers on the spot, about to switch to automatic operation.

'Too late!'

　The reconnaissance shikigami have no combat capabilities. That's why they are often ordered to 'destroy themselves when the connection is broken'. This is because that way, the surgeon will not be identified.
　However, the rigid jutsu does not allow for such an outcome. In the small amount of time between the switch to automatic operation and self-destruction, he released a tag filled with spiritual power.
　The tag ignited in the air and turned into a huge flame bullet that landed on the white crow. The white crow was engulfed in explosive flames as an impact occurred that caused the wards to creak.

''Tch, I made a mistake because of my irritation.

　The Yin-Yang Masters around them kept their mouths shut at the attack, which was clearly too much to attack a scouting shikigami. It was only natural for them to behave in such a way that they would not displease the ki-fire when they witnessed the scene.
　The person who had unleashed the magic was growing frustrated that he had erased the traces of the surgeon with his own hands, and was on the verge of exploding at any moment.

　In the midst of all this, a sorcerer notices a change.

"There's a white crow!

　Everyone here looked towards the smoke explosion in response to the words. The next time the smoke cleared, there was an unharmed white crow there.

''Really........''

　I observe it for a while, but the crow shows no signs of destroying itself. On the contrary, it can be sensed that it is gazing intently at the airflame and turning hostile.
　The Kaira can't hide its surprise, and its eyes widen. Then, with a beastly smile on his face, he chanted a jutsu.

''Omocha! Flame, release, many, many bullets, 'continuous flame wall'!

　Each of the bills scattered in the air turned into scorching flame bullets and headed towards the white crow. The flaming bullets split into smaller and smaller pieces as they advanced, turning into countless fine flaming bullets. As if it were a wall of flames, the cluster of small flame bullets that had been turned into a wall of flame left no room for the white crow to evade. A landing is inevitable.

　However, the sorcerers are astonished by the actions of the white crows, which they had not even expected.

''Ridiculous!''

　The white crow didn't avoid the wall of fire, but charged into the center of the wall. Then, by releasing its own spiritual power, it generated a shockwave and broke through the wall.

''I see, so he struck his spiritual power and blew up my blast of fire!

　The air flame had no intention of killing the crow with this attack. It was an attempt to expose the seed of the attack with an attack from which there was no escape, in order to find out why it was unharmed even after being hit by a flaming bullet.
　Although the crow was unharmed, the plan of the airflame was a success.

''If it's going to blow me up, I'm just going to bludgeon it with more force than that! Flame, artillery, annihilation, inducement, bombing, 'annihilation flame follow-up bullet'!

　The flaming bullets that contained a tremendous amount of heat turned into light bullets and were released into the white crow.
　Judging that it was impossible to intercept the crow, the crow avoided the incoming light bullets. However, the light bullets change their trajectory and track the crow.

That thing won't disappear until it hits its target. What do we do now?

　The speed of a crow far exceeds that of an ordinary shikigami. However, the speed of the light bullets surpasses that crow as well. The distance between him and the escaping crow is gradually closing in.
　However, even while looking at the light bullets that are closing in behind them, the crows are not in a hurry. In the next moment, the crow began to release a spiritual wave toward the back.

''Nah, you're shooting backwards too!

　The speed of the light bullets is weakened by the spiritual wave released to the rear. And the crow itself accelerates.
　The scene was not only a surprise to the air flames, but also to all the sorcerers who were watching this battle.
　This was because no one had ever heard of a reconnaissance shikigami with a means of attacking with spiritual power waves. Furthermore, he was capable of judging the situation to the extent that he could accurately respond to the situation on the spot. That would mean that he had the ability to think on par with a high-level battle shikigami.
　The many facts that surpassed their comprehension caused all of the sorcerers present to reveal their astonishment.

　However, the facts that astonish the sorcerers continue to amaze them.

　The crows being chased by the light bullets released a spiritual wave behind them, but they did not dare to pull away. By descending vertically with the light bullets drawn at close range and cutting back just before the end, he landed the light bullets on one of the buildings.

''Oh, the fortune seller ah!

　The shrill cries of the inhabitants echoed through the air.
　A defensive ward had been set up in one corner of the grounds, and within it, non-combatants were huddled together, watching the battle.
　The resident priest crumbled to his knees as he saw the fortune seller erased from the wards.

'Hahaha! You're the first one to dodge the Flamethrower's Pursuit Bullet like that! Funny! Come on, bakki!

　Regardless of the thoughts of the inhabitants, the stiffness called for more destruction.
　The space behind the air flames distorted and an explosive flame was generated. Then, a demon wearing the explosive flame appeared.

''Ah, that's Kiena-sama's servant demon.''
"So you're an explosive demon that's only summoned when the Master of the Flame gets serious.
Everybody out!

　The magicians flee into the wards where the non-combatants are evacuated.
　The demon "Bakki" is the servant of Kiien Tsuyoshi. As its appearance suggests, it is a demon that manipulates explosive flames.
　Like Kienki, it is a master of wide-ranging attacks, and can shoot flames from both hands and feet, the mane of its back, and every other part of its body. Once it has been summoned, you are obliged to evacuate the area around it because if it rampages, it will turn the entire area into a sea of fire.

"My....temple...

　Realizing the essence of that demon, the abbot cries as he stares into the void.

''Let's go!''
Goaaaaaah!

　With a call of air flames, the Bakki also released a roar at the white crow.
　The roar was enough to shake the wards, but the crow remained stationary in the air and was unaffected.
　Then it raised its beak as if to say, "Come and get me," and looked down provocatively at the Qi Flame and the Bakki.

　On this day, the legendary battle that will be passed down to future generations among Yin-Yang Masters had begun.
