Hakuryuu spread her wings and soared to the final floor’s ceiling, which was around 500 meters above the floor.

Her goal was to leave Sitri’s field of vision.

Both Youko and Hakua acknowledged Sitri’s power.

Hakua, the strongest among the colored dragons, and Youko, the monster who stood at the pinnacle of the demonic race, even overpowering majin were powerful enough, but they decided that they wouldn’t be able to win against Sitri if they fought against her individually.

And so, they both decided to cooperate for this battle.

This was the first time for them to collaborate in a battle, but it wouldn’t be an exaggeration to say that the person standing before them could be considered the strongest demon king of all time.

They wouldn’t win unless they joined hands.

Both of them had a common goal — and that was to defeat this strongest demon king no matter what, for the sake of obtaining Halt’s reward. This move would be the most suitable to achieve that goal.

Youko didn’t miss how Sitri’s gaze followed Hakua’s flight.

She used that instant to condense the mana stored in her nine tails, compressing into an ultra-dense form before releasing it towards Sitri.

It was the lazer attack that Youko used to dissolve half of the majin’s body in an instant when they encountered him on the outskirts of the Holy City of Sanctum.

Sitri —

Brushed it off with one hand.

“Wha!?”

Youko was also shocked.

“…You Bakemono”

“Oh my, same to you —”

“Take THIIISSS~!!!”

Sitri’s words were cut-off when Hakua suddenly fell down at high-speed.

Hakua had circled the ceiling of the final floor until she reached the fastest acceleration while repeatedly casting layers of hardening magic and gravitational magic to herself as she hurled herself towards Sitri.

Hakua had placed everything on the line, and yet Sitri easily stopped her.

“ — Huh?”

Hakua was flustered when she didn’t understand what just happened.

She attacked Sitri with enough force to create a crater few hundred meters wide, but Sitri stopped her on her tracks with those puny arms of hers.

And the impact of that crush didn’t even dent the floor beneath her in the slightest.

She was aware of Hakua’s movements.

And, she even managed to avoid Hakua as she charged towards her.

Sitri used anti-gravitational magic and reduced the speed and weight of Hakua.

Moreover, she gently caught Hakua by her head, reducing the load of the dragon’s body.

It was a powerful technique that was only possible by the overwhelming difference in their abilities.

“L-let me go, I said!!”

Hakua couldn’t escape when her head was caught, so she trashed her tail on Sitri.

It was the Hakuryuu’s tail attack that was enough to crush the demon Guzion.

— But, it was mere child’s play for Sitri.

“This is what happens to naughty kids!!”

Sitri released Hakua’s head and grabbed her by her tail that was about to crush her, then she swung the gigantic body of the white dragon before throwing her towards Youko.

“—!? S-Sorry!!”

Youko hastily avoided Hakua’s body as it came hurtling towards her in top speed.

“Fugyu!!”

Hakau was thrown towards the far end of the floor, and she screamed out in pain as she crashed into the wall.

“You made the back of my hand numb, so I have to return the courtesy.”

“Eh?”

Youko had been watching Hakua as she flew past her, so she reflexively turned when she heard Sitri’s voice. The former demon king was standing behind her, ready to flick her forehead.

“Right?”

“FuguaaahhhhhHHHH!!!!”

Youko was blown away towards the end of the floor just like Hakua. She got hit by the world’s strongest flick between the nine-tailed fox’s brows,

She had activated a thousand layers of magical barrier in the instant before Sitri’s fingers touched her forehead, but it was to no avail.

“Still want to continue?”

Demon King Sitri drew closer towards Youko and Hakua, who both collapsed near the wall at the edge of the dungeon floor.

“I-I still….still can’t lose against you.”

“Yup, this is nothing.”

Both of them were trembling as they managed to stand on their feet.

They were shaking from the Damage that they received, as well as from terror.

“I see… Yes, indeed. Alas, Danna-sama’s reward! Just how wonderful it is to the ears. I truly, painfully, understand your refusal to give-up. However —”

Sitri summoned a lump of mana from her right hand.

It was the Death’s Mass that the strongest demon king of all time materialized by pushing her power to the limit.

“It’s essential to know when to give up.”

Sitri raised the Death’s Mass high above her head.

“A, Ah AHHHHHHH!!!!”

“N-no, I don’t want to….I don’t want to diiiiieeeee!!!”

Youko and Hakua could foresee their deaths.

“Please be at ease. All the things that meet their demise within this dungeon can be revived to no end by Danna-sama’s power, it seems.”

Sitri lowered her hand with a smile.

Death came rushing towards Youko and Hakua —

“Alright, time’s up.”

Halt appeared before Youko and Hakua and caught the Death’s Mass.
