“There’s no reply from any of the units Libest-sama.”

In the demon kings castle, Libests subordinates are starting to panic over the loss of communications through <Liikus>

“If we can’t communicate with <Liikus> what are we supposed to do? Have they already been beaten in battle? Should we attack with the main unit instead of the scouts?”

“No. This is very strange. No way were they all beaten without at least one of them using <Liikus> to inform us. We should consider that they have set up traps outside. Carelessly moving about out there is probably what they want.” (Libest)

Libest seems to have decided that staying put is the best course of action since they can’t see the enemies hand.

“It’s vexing but let them siege us. It’s not too late for them to underestimate us and give us the chance to strike back.” (Libest)

There’s also the terrain effect of being in the demon king castle. If Libest [King] is in the castle then his power is strengthened. The true value of <Guys> comes from siege warfare.

“Save your magic and the moment they show up really give them something to look at.” (Libest)

“Understood!”

They still don’t seem to have realised what’s going on while they stay in the castle and store up magic power.

After a short while.

“Hmph. Finally here? Let’s finish it.” (Laos)

Laos emerges from the east and confirms the castle.

“You’re too hasty Laos. It’s boring if you don’t play around a little”. (Heine)

Heine appears from the west.

“Both of you are too careless. We still don’t know what will appear from the castle. Please proceed more cautiously.” (Ledoriano)

Ledoriano appears from the north.

“I see them. North, east and west. It’s three heroes [Braves]!”

Libest’s subordinates raise their voices.

“Did they split up instead of acting as one group? I don’t suppose it matters now. Let’s go! Show those guys the power of the demon king academy!” (Libest)

“Roger that! Preparing Absolute Water Annihilation Cannon <Rio Eias>!”

“<Rio Eias> preparing! Magic formation begin!”

A huge magic formation appears on the castle and turns into a turret above one of the gates.

“Start supplying magic power!!”

The formation activates as is receives magic and light gathers in the turret.

“Ready to fire!!”

Magic sights are aimed at Heine, Laos and Ledoriano.

“Here we go. <Rio Eias> fire!!” (Libest)

At that moment the lake turns white and is wrapped in holy light.

With Heine, Laos and Ledoraiano as the tip, a triangle formed of magic lines appears. From the centre, a huge magic formation appears and covers the demon king castle in light.

“……Libest-sama. Magic power and the power supply itself is decreasing rapidly. We can’t maintain the formation!”

The <Rio Eias> formation deployed on the castle disappears and even the whirlpools created around the castle have disappeared.

“…….Wha…. We can’t draw any magic out. At this rate, the demon king castle will….!!”

As soon as the [Guardian] speaks a sound rings out and the castle breaks in half and gets swept away in the water.

“UAAAAAAAAAAAAH…..!!”

The outer walls, floors and ceilings come apart and everyone inside was dragged out.

Due to the castle collapse, the water becomes stormy.

Libest casts Flight <Fres> and flew through the water somehow managing to regain control and begins re-establishing order.

“Everyone calm down and prepare for the enemies attack. I’ll help you!” (Libest)

“Ohh? Can you do that?” (Heine)

Heine appears behind Libest.

“Is onii-san a demon king [king] who will become a demon emperor in the future?” (Heine)

“What about it?” (Libest)

*Fufu* Heine laughs.

“Look at that. Do you understand?” (Heine)

Libest turns to look at where Heine was pointing and a flash of light appears.

The rubble from the collapsed castle is scattered in the water along with the other students and from the lake floor countless flashes of holy fire are firing out.

“It’s no good!……… Anti-magic can’t be used!………GUAAAAAAA!!”

“KYAAAAAAAAAA!!”

The lake had become complete pandemonium.

To the listening Libest, Underwater Activity <Coco> is barely working as their voices augmented by magic are becoming feeble.

“Ha! You’re weak! If this happens you Mazoku are weak!!”

Laos fires off multiple Holy Flames <Cipher> burning one student after another.

Both anti-magic and recovery magic were sealed by the barrier scattering the magic for them into the water and making them useless.

“Ahahahaha, how unsightly. I have to laugh if such a pitiful person is a future demon emperor. What is the demon king academy teaching you? How to let your comrades die without helping them?” (Heine)

Libest’s eyes sharpen at Heines words. He tries to pull his demon sword out but he can’t due to his low magic power.

“Why is your magic weakening? Would you like me to tell you?” (Heine)

Heine was totally playing with Libest now.

“The holy water that mixes with this lake creates a special barrier. You can use it as a source of magic power if you can draw it out but if not it will hinder your use of magic power. I say that but you cant use it at all so it would be hard for you to do.” (Heine)

Heine deliberately exposes the holy water magic tool to Libest.

“So it was such a thing…… Even so, you should have remained quiet to the end!!” (Libest)

Libest accurately analysed the flow of Heine’s magic power and uses the holy water as a magic tool in the same way.

And that was the trap.

“………Ah……….” (Libest)

The power of the holy water penetrates directly into Libest’s origin. Holy water benefits humans but is poisonous to mazoku. The holy power tears his body inside to shreds.

Libest bleeds from his whole body.

“Ahahahaha! Failure failure! The students of the demon king academy can’t do such a difficult thing.” (Heine)

Heine mocks Libest and raises his right hand.

“Come my holy sword. Great sacred ground sword Zeele.”

Light gathers in his palm and instantly materialises.

A holy sword emitting a deep green glow appears in Heine’s hand.
