"You are indeed very powerful. Your only weakness is this piece of the Demon King's Sword.

　A black glow overflowed from Zegert's forehead and chest.

"A piece of the Purgatory Demon King's Sword (Ladis)...?

　''And two of them.

"You once fought a brave man who possessed the shard, and your strength was severely weakened?

　Zegert chuckles.

"The Miracle Armor that you carry inside your body, the Miracle Armor that the brave man carries, and the shards of the Demon King's Sword interfered with each other - that weakened your power as a Demon King.
Interference...?
The Miracle Armor is a weapon that embodies the power of a god. And the Purgatory Demon King's Sword, a ritual tool that holds the power of the Demon King. When these two powers rise within you at the same time, they cancel each other out and your 'magical power as a demon king' will be weakened indefinitely.

　And Tsukuyomi.

''This phenomenon occurred because you are different from the previous demon kings... you are a former human and have both the divine armor and the power of a demon king in your body at the same time.
"In the past, this condition was only met when I fought you and a brave man who had both the Miracle Armor and the piece of the Demon Sword in him, and I learned that from him. Therefore, I thought I could weaken you if I reproduced the same conditions.

　Zegert laughs.

I'm sure you'll be pleased to know that I'm not the only one. I also used Tsukuyomi's magic technology to modify the arm of the brave man and put it on my back. I've learned to control the Miracle Armor.

　I see.
　So the sub-arm sprouting from Zegart's back is made from the arm of a hero he defeated in the Second Battle of the Brave Invaders.

　That's why Zegart is able to control the Miracle Armament by using the arm.

And I put the two shards in my body and in the Miracle Armor. The result is - as you can see. And as you can see, the tactics he taught me worked wonders.
He...?
'We made a deal. To advance the high road. With the enemy.

　A slight bitterness appeared on Zegart's face.

''Enemies........''
I don't have to tell you.

　Zegert grins.

'Well, let's get on with it!

　Zegert howls and unleashes his spear.
　He also mixes in his own claws, fangs, and tail to unleash a variety of attacks.

　I intercepted them with fire and lightning magic, but they were all easily blown away.
　With the power dropping to this level, I have no choice but to raise the rank of the spell further.

''Breakthrough Thunderbolt (Mega Thunder)!

　He unleashed a top-grade lightning spell.

　A lightning bolt with the power to scorch away even space, however.

It's useless!

　Zegert's freaky armor cut me off.

　I guess this isn't going to work either.

Lucifer's Shield!

　I put up a defensive wall and retreat while shielding myself from his attacks.
　But that protective wall is also cracking under Zegart's continuous attacks.

　It won't last long.

"Are we already on the defensive?　Aren't you the most powerful demon king ever?　Kuhahahahaha!

　Zegert was happily winning.
　With a high-pitched sound, the protective wall shattered completely.

''Chii........''

　I clicked my tongue and retreated further.
　In that case, I'll use this one....

"Convergence-type Vanity Blade!

　I'm going to create a magical sword that is my trump card.
　No.

It's not going to work.

　The jet-black energy sword that appeared in my hand was a blur, a blur, and it dissipated.

　The magic power did not converge into the shape of the sword.
　Don't tell me that the magic power is almost gone already!

　It's as if I've returned to the days when I was a human hero.
　No, in fact, my status now might not be much different than when I was a human.

　After my reincarnation, the power I had as a demon king is gone...?

''You're not an enemy, as you've lost even your magic power!　Scatter now and hand me the demon king's throne!

　Zegert steps in for the last time and unleashes his spear.

　Oh no, I can't prevent it...!
　I freeze up, I cringe.

　The sharp tip of the spear is in front of me, and...

''Huh........?''

　However, the expected pain and shock did not come.

　Gingh!

　Instead, I hear a sound that seems to echo in the pit of my stomach.

''You........?''

　The surprised voice was uttered by both me and Zegert at the same time.

''I won't let this one point his blade at you, Zegert.

　The Beast Emperor's spear was caught by Regal, who flew out from the side with his sword──.
