The SS (double-es) class divine sword, the Kusanagi no Tsurugi, was used at the end of the Heian period in the Battle of the Genpei.

　It was during the Genpei War at the end of the Heian period.
　It is the most supreme treasure in Japanese history, the divine sword that was scattered and lost at Dannoura, the final battlefield of the battle at the end of the Heian period.

I never expected it to have landed in another world like this. That's because you can't find it no matter how hard you look for it.

　And the Sword of Kusanagi is a divine sword born from the body of a defeated dragon.
　This divine sword is said to have been born from the body of a defeated dragon, and it possesses a certain 'inherent divinity' that I likened to my own mythology of rebirth from destruction.

''It's an SS-grade divine sword, the Sword of Kusanagi!
　While holding the broken sword in my right eye, I call out forcefully--!

Activate the Inherent Sacredness, Yamata-no-Orochi.

　That moment...

　Boom.
　And the Sword of Kusanagi pulsed loudly.

　It was, if I may say so, a beat of joy.
　The fact that I had encountered a transcendent being named Shinmeetsuhaou, who could understand me as an SS (double-es) class divine sword - that was a joyous moment.

　In addition, the

　Boom--!
　The sword's blade trembled strongly as it was broken.

　Then, like a giant blue whale swallowing a whole school of krill, it began to fiercely suck in the golden particles released by Amaterasu!
　To heal its broken body by feeding on the immense golden power--!

　The Yamata-no-Orochi.

　That's right.
　This divine sword that was born at the same time as the annihilation of the divine dragon...

Through the inherited 'inherent divinity' of that myth, it will be born anew and manifest itself as 'the most suitable form for the user'--!

　The Sword of Kusanagi stores the inexhaustible power that flows from Amaterasu to the extreme, while its blade is reborn!

　And finally -- finally.

　The Sword of Kusanagi has been reborn in a form optimized for the Mythical SS-class cheat Shinmeetsuhaou!

　This is a Japanese sword with immense power, shining with dazzling gold.
　It's a divine figure that lives up to the name of Japan's most treasured divine sword, and it's now appearing in my hands!

This is the true form of the Sword of Kusanagi.

　It's a terrifying presence that even makes you feel twitchy and awesome just by being in your hand.

"But that's it, that's it, that's it--

　When it comes to the SS (double-es) class, this guy and I are equals now.
　I don't need to be shy about it because it's a legendary divine sword.

"Hey! The Sword of Kusanagi. After pretending to be asleep for so long, you've eaten my strength for all it's worth. Have you had enough?　So now it's your turn to satisfy me, huh?

　The Sword of Kusanagi trembles lightly in my hand, as if to say, "Of course I understand," but it's not.
　Ok, good boy--!

　Once the rebirth of the Sword of Kusanagi and communication was successfully completed, in other words, there was only one final task left to do--.

Let's go, Shin-enryu!

　From now on, the only thing you can do is to beat this thing, and that's it--!

''Oh, yeah. I'll tell you first, I don't have any intention of fighting other SS (double-es) classes for a long time in a city like this. I've had enough of fighting with you. I don't want to cause any more damage, and after a little bit of fun, I'll finish it off as soon as possible--!

　By the way, it's my true intention to end this without any play, and I want it to be over as soon as possible.
　I want this life-taking battle to end quickly and return to the daily life of an irresistible harem.
　I'm really serious.

　It's just.
　Right now, I have a piece of the heart of the Shinmetsuhau, the unrivaled warrior of the world, inside me.

　I've got to satisfy the strong enemy called Shin'en-ryu, who is desperate to fight and has no specifications.

　I took a fresh look at the beautiful golden swing of the Kusanagi Sword, and as I readjusted my position.

　Chaki--
　There was a slight sound like metal touching each other.
　It is a sound often made when a sword is held in a period drama.

　Normally a well-maintained Japanese sword does not make this kind of sound.
　This is just a standard feature to enhance a scene.

　Of course, the SS-grade divine sword "Kusanagi no Tsurugi" cannot be such a poorly maintained sword.

　In other words.
　In other words, the Kusanagi Sword deliberately made a noise to suit my taste.

It's quite a joke, isn't it? I love it--!

　As soon as I said it.
　I had appeared in front of the Shin-En-Dryu by stepping in with divine speed.

　And then he swung out the Kusanagi no Tsurugi sword directly--!

Hey, uh...
　It's nothing, it's just a regular kesa-kiri after a quick shake up.

'Gluaaaahhhhhhhhhh!

　That's all it took, just a single blow.
　A huge crack appeared in the dragon scales of the Shin-En-Dragon!

　Every time I swung the Kusanagi no Tsurugi, with one more strike and then two more, the dragon scales, which had never been injured no matter how many times Niall and I attacked, were severely damaged.

　There was no counterattack.
　It is no longer possible for the Shin-En-Dragon to keep up with the overwhelming speed of my - Shinmeetsu-Haou.

　I was only aware of what the True Dragon's Eye had done to me.

　This was because.

It's a good thing that you are a fast flyer, because by nature you fly through the air at high speed, and you use your dragon scales to repel all of the chitchatting attacks and aim at the enemy with your deadly dragon breath. You are a complete mid-range air force...

　That's why in this earthly battle, the Divine Demon Dragon can't unleash even half of its original power.

''If it was against an S-class cheat's 'Sword Saint', that might have helped. But the SS-class Shinmetsuhaou is not so slippery--?

　Even as I speak, I avoid the attacks of the Shin Demon Dragon with plenty of time to spare, and then I send out one attack after another.

''Even so, your combat ability as an overwhelming SS class. If you were in the sky, the result might have been different. Of course, even if you try to escape into the sky now, I'll shoot you down instantly the moment you try to fly.

　Even if the Shinmeetsuhaou wanted to fight for real, being attacked while flying at high speed was a complete no-good, no-go situation considering the amount of damage it could cause.

　Do you know that the 《Shin'en Ryu》 would also be shot down the moment it flew?
　He didn't seem to have the slightest idea of flying up with those huge wings.

　But you know what?

We can't take it easy, man.　You still have an arrangement, right?　There's a power you've been hiding - your Inherent Sacredness, isn't there?　Then show me that thing, Shin'enryu. From now on, I'm going to crush that dragon's pride and crush it without a trace!
