The Supreme Teigu, the Imperial Guardian [Shikoutazer], also called Supreme Tesser in the anime, was a weapon created by Haruki a thousand years ago exclusively for the royal family. What sets this Teigu apart is that matching its wavelength isn't enough—only those with imperial blood can wield it. Naturally, as a Supreme Teigu, its power is extraordinary.
Its sudden emergence at this moment is no coincidence. To understand, we have to rewind just a few minutes...
"Report!"
A panicked voice rang out from the distance as a figure rushed into one of the palace chambers, where the young emperor, the Prime Minister, and several high-ranking imperial officials were gathered.
"Why the panic? Speak calmly," the Prime Minister said, unhurried and composed.
"Yes, Your Majesty, esteemed ministers—I've just witnessed Great General Budo's defeat. Tens of thousands of rebel troops are already flooding into the palace!"
Hearing the Prime Minister's measured tone, the messenger trembled slightly before quickly kneeling. After bowing to the young emperor and the Prime Minister, he finally delivered the report.
"What do we do now?!"
"The thousand-year empire, gone just like that?!"
The moment his words landed, the ministers erupted into a chorus of reactions—fear, worry, sorrow. The entire room was a mess of emotion.
"What are you all panicking for? Why are you so quick to assume that the allied forces have won? Who said the Empire has lost?!"
Just as the uproar intensified, the Prime Minister spoke. His voice was calm, showing not even a trace of concern or fear, despite the rebels already being at their doorstep.
Everyone couldn't help but be puzzled. Given the situation, Prime Minister Honest should've been the first to go—but his demeanor didn't match the crisis at all.
"Prime Minister, things have gotten this far. If you have something up your sleeve, now's the time to say it!"
The young emperor turned toward him, unable to hide his urgency.
"Yes, Your Majesty."
The Prime Minister bowed respectfully. On the surface, he had always shown the utmost deference to the young emperor. He continued,
"Your Majesty, think about it—how has the royal family lasted for a thousand years? Could it be without any secret means of survival? Right beneath our feet lies the Imperial Guardian, the Supreme Teigu [Shikoutazer], passed down through generations of emperors. Only a true heir of the royal bloodline can command it. It is said to possess power that rivals the gods. With this Teigu, you can wipe out the rebel scum plaguing the Empire. There may be sacrifices... but it will be worth it."
As he spoke of the Supreme Teigu, the Prime Minister's expression turned fervent, almost fanatical.
That was the moment the Supreme Teigu made its appearance.
Without hesitation, the young emperor activated Shikoutazer. The crystal orb embedded in its forehead began to glow a menacing red.
Then, locking onto the area of the palace with the highest concentration of rebel forces, it unleashed a massive pillar of crimson energy...
"Boom!"
With a deafening roar, a towering column of fire shot into the sky—like a nuclear bomb had gone off. Everyone in the blast zone was instantly vaporized.
The Supreme Teigu's power is said to rival that of a god, not because of combat prowess in the traditional sense, but due to its sheer destructive force.
When Haruki crafted this Teigu, he focused heavily on maximizing its offensive capabilities. However, due to its massive size, its movements were relatively sluggish. Even so, its colossal frame and near-indestructible construction made it far superior to any other Teigu.
"What... what is that thing?"
"Hey, can something like that even be defeated?"
Its massive presence alone had already stunned the allied forces—but after witnessing its devastating power, any confidence they'd regained quickly crumbled. Many lost the will to fight altogether.
"Mr. Susanoo, what is that thing? Why is it so massive?!"
The Supreme Teigu's appearance had equally shocked the members of Night Raid. Driven by curiosity, Tatsumi turned to Susanoo.
"I've never seen it before, but judging by its size and that kind of firepower, there's no doubt—it's the Supreme Teigu."
Susanoo paused to think before giving his answer.
"I can't believe it really exists... No wonder the Prime Minister always acted like he had nothing to fear."
Najenda muttered, her expression a mix of awe and realization.
"Boss, what exactly is the Supreme Teigu?!"
Everyone turned their eyes toward Najenda, curiosity burning in their gazes.
Seeing their interest, Najenda didn't hold back. She explained the rumors surrounding the Supreme Teigu in simple terms.
After all, the Supreme Teigu had always been shrouded in mystery. Not just to commoners—even among the nobility, few knew whether it truly existed. Najenda herself only knew fragments of old tales.
...
As Najenda briefed the others, just like in the original tale, the young emperor began using the Supreme Teigu to launch an assault on the capital.
Of course, he wasn't aiming at civilians—he'd spotted rebel forces disguised among the crowd. But with an attack of that scale, civilian casualties were unavoidable.
"Damn it! He's attacking the people of the capital—how despicable! Everyone, stop him!"
Seeing the destruction unfold, Najenda no longer cared about the Supreme Teigu's threat. She shouted for the Night Raid to intervene and stop it.
Clearly, they had no idea what was really going on inside the city. To them, it looked like the young emperor was simply venting his rage by massacring innocent citizens.
But before they could get close, something happened that left everyone frozen in shock.
Two beams of red light—originally fired by the Supreme Teigu—suddenly reversed course and flew back the way they came. One struck the Supreme Teigu itself, while the other hit Prime Minister Honest, who had been watching from a nearby rooftop.
With a thunderous impact, Honest was blown off the rooftop.
Despite being made of materials tough enough to shrug off the power of even Demon Armor [Incursio] and Carnage Incarnate [Grand Chariot], the Supreme Teigu began to smoke and crack from its own attack.
As for Honest, a mere flesh-and-blood human, he never even had a chance to react.
Just like the soldiers who were caught in the initial blast, Honest was instantly vaporized.
The tragic part? He never even figured out how he died.
