I was puzzled.

　The descendants of the Demon King boast a high amount of magical power, so some people use them as a source of living magical power.
　However, in order to do so, the descendants of the Demon King have to undergo conversion surgery and be treated atrociously.

　In fact, Arte has been enslaving and using the girls who are descendants of the Demon King, crushing them and making them crippled.
　And they were trying to gain more power.

　But I'm sure Flora was against such terrible things.

　Even though she was her sister, Flora didn't agree with everything that Arte was doing.
　Flora had certainly said so when they had met by chance in the Great Library.

　And yet, she actually treated the Demon King's descendants like her sister, treating them as tools to obtain power.
　And he was able to use the astrological attacks that required enormous magical power not just once, but twice during the battle.

　Then everything that Flora said was a lie.
　Maybe there was no possibility of her becoming our ally in the beginning.

　Flora noticed my gaze next to her and smiled sadly.

''I'm a coward, Solon-senpai.

　After Flora said that to me, she immediately moved on to activating her astrological magic.
　This time it wasn't to destroy the magic circle, but to defeat the enemy Saul himself.

　At the same time as Flora began chanting, Creon gave the signal and the vanguard adventurers unleashed their swordsmanship against Saul in unison.

　Saul was too busy dealing with the swordsmen to stop Flora.

''Crash!''

　At the same time as Flora shouted, Creon said, "Retreat! I called out to them.

　All at once, the vanguards jumped back.
　In almost no time, a mass of burning attack magic hit Saul with a blinding light that was impossible to see directly.

　If it had been a normal demon race, it would have been burned up by this.
　But Saul still stood there, looking unconcerned.

''You've dabbled in the power of the forbidden, and it's still not enough to defeat me.

　But Flora isn't the only one using the power of the Demon King's descendants.
　Of course Arte is, and maybe even Creon is sacrificing the descendants of the Demon King.

　Arte raised his willow staff again and fired a bundle of seven-colored magic at Saul.
　This is probably another way of using the magic of the Demon King's descendants.

　No matter how Saul is, he is not completely unweakable.
　The successive attacks had caused Saul to lose a lot of magical power.

　Creon stepped into Saul as if to fold it up.
　The holy sword shone blue and flashed in a flash.

　Saul was slashed deeply and fell to the spot, and then began to glow faintly white and disappeared without a trace.

　All that was left was the crystal sword he was holding.

　It was a quick and easy thing to do.
　The guardian of this ruin, who had lived for two thousand years, had been defeated.

　To a third party, it might look like this feat was accomplished by three great adventurers: the Holy Knight Creon, the Wise Arte and the Astrologer Flora.

　But their hands are stained with the blood of the Demon King's descendants.

The fake saint is defeated. It's our victory!

　At Arte's declaration, the adventurers fell silent for a moment and then erupted in cheers.
　The capture of the Necropolis had been accomplished.

　At that moment, the back wall of the hall begins to open up from side to side with a roaring sound.

　The throne room of the ancient kingdom appeared in front of us.
　The space was glowing with silver.

　I remembered the legend that the walls, floor and ceiling of the ancient kingdom's throne room were made of platinum.
　And there was enough gold to reach the ceiling.

　Nope.

　It was a giant covered in gold.
　It didn't budge, but it was clear what it was.

''These are the Seven Demon Kings of Vendidad. This is Aka Manaf, the one who destroyed the ancient kingdom.

　Creon murmured.
　It is true that the demon king's appearance is just as the legend says.

　The demon king is not a mythical being in a fairy tale.
　This is the true purpose of Creon and Arte.
　They intend to resurrect the Demon King in order to use it in their war against the neighboring country and to obtain more power.

　And all that is needed to revive this Demon King is to offer Filia as a sacrifice.

　That's the only thing we have to stop.
　So, for me and my friends Notaras, Laskarus, Nasha and the others, this is where the real battle will start, with Creon and Arte as the enemy.

　It was supposed to be.

　I see Flora wandering around in a huff.
　Then Flora went to the position where Saul had been standing and picked up the crystal sword.

　None of the adventurers, drunk with victory, paid any attention to Flora's actions.

　Flora approached Creon with the crystal sword in her hand.
　Creon gave her a look of, oh, well, then he smiled.

''The reason we won this battle is because of Flora. You're the one who did the most good.''

　Creon held out his right hand to Flora to shake her hand.
　But Flora did not respond to it.

　In the next moment, the crystal sword in Flora's hand was stabbing deep into Creon's chest.
