"Now then, let's stick to the plan, Group A and B will attack the North and South sides, while C will infiltrate amidst the chaos and rescue the heroes. Understood!?" said Vincent in a loud voice.

"""UNDERSTOOD!"""

Groups A and B immediately launched their attack, since they are under illusion magic, they would look like demons invading a human territory. The 3 royal knights who are behind me and Nathia finished preparing themselves.

"So you two are the mercenaries that the second prince hired? Since both of you are our superior in this mission, we will do our best in order to execute your commands." the knight said after equiping his helmet.

"We appreciate it, the three of you will only need to stall time for me with my companion, while I rescue the heroes from inside the castle, after I give you the signal which is this red stone, the 4 of you will retreat immediately to this camp using the teleportation stones that princess Lily gave to you." I gave them the summary of the plan while I scan the layout of the kingdom in the distance.

"But, are you sure you can go inside the castle all by yourself? There will surely be a lot of skilled fighters on standby with the king, rescuing all 42 would be difficult." replied the other knight.

"Your worries are not needed, my teacher can easily take down 50 fighters on the same level as the royal knights."

"B-But still-"

"Enough with the conversation, prepare for infiltration. Group A and B has already engaged in a battle with the enemy. We will commence the operation in 3 minutes."

""Yes!""

After 3 minutes, the five of us secretly snuck inside the walls of the kingdom. Since the enemy soldiers are in disarray because of the sudden attack, it was easy to sneak in. There were also soldiers inside who are heading out to help, but we dealt with them easily and secretly. It tool us 4 minutes to reach the town plaza.

There are about 200 soldiers receiving orders from their superiors present, all of them are wearing chain mails and each of them has a sword and buckler, just like a normal knight.

"I can see the entrance to the king's throne. Commence the attack, keep them busy until I give you the signal. Begin!"

Nathia and the three royal knights launched a surprise attack from the shadows and caught the enemy off guard. After seeing them engage in battle, I quickly dashed to the front of the huge door leading to the king's throne room.

"Hmm? this presence..." I detected two familiar presences coming from inside the throne room.

"H-How did a demon get past our defenses? Don't take another step!" said one of the three full plated knights guarding the huge door.

"Out of the way."

I flicked a pebble into the forehead of the two guards, it penetrated through their helmet and head, killing them cleanly in an instant.

"W-What did you do!?" the remaining one shuddered in fear as he witnessed his comrade's fall.

I kicked him hard in the stomach which sent him flying backwards, slamming open the door in the process.

I finally confirmed my thoughts when I saw the two of them through the cloud of dust.

"Don't you think the students' field trip location is a little bit too far this time... Tanya?"

I said to the woman in front of me.

"L-L-Lu...cas-sama, y-y-you..." Tanya who finally saw me stuttered as she called out to me.

"Let's save the conversation for later, first, I need to get all of you out of this place."

"U-Understood!" replied both kagami and Tanya.

"A-A demon! Guards, kill this demon right this instant!" shouted the king.

30 guards quickly surrounded and pointed their weapons at me, but before they could take any further actions, Tanya and Kagami quickly sprung into action, quickly knocking them out in just 4 seconds.

"Vermin like you doesn't have the right to touch him!" said Tanya as she let out her immense murderous aura.

"Whoaaa, Ms. Tanya is so awesome! She fought on the same level as the sky king!" the students exclaimed when they saw what just happened.

"Of course, after all, this teacher of yours is the famous 2nd Emissary, Valkyrie Queen, Tanya." Kagami said with a smug look.

"Kagami! you-"

"Ooopps? eheheheh"

"Ehh!? M-Ms. Tanya is... the 2nd Emissary!?" The entire class shouted.

"I will explain this to you children later, first, let's get out of this place first. Your majesty, do you have a plan?"

"Yes, which one of you is the class president?" I asked the class.

"I-I'm here..." a girl popped out of the class and walked to me.

"Take this gem, have the entire class hold each other's hands, all of you will be teleported somewhere that looks like a basecamp, don't panic if you see people in white robes with staffs, they are allies. After you arrive at the place, pretend that you don't know about Tanya and Kagami. Now then, we don't have much time to waste. Tanya and Kagami, hide in the shadows and follow me secretly."

The gem at the class president's hands started glowing and a huge magic circle appeared below the 40 students.

"STOP THEM!" The king shouted, 40 more knights came in from outside and tried to stop us, but Tanya dealt with them in just a few seconds.

The entire class disappeared and got teleported to the base camp. I took out the red stone from my pocket and threw it up into the skies, penetrating through the roof easily. After a few seconds, it emitted hundreds of red rays of light.

"That's the signal! retreat!" said Nathia when she saw the red light. She and the other three took out the gem stone and teleported back to the basecamp.

All of the soldiers started retreating back to the base camp when they saw the signal.

"You two, let's go." I said to my subordinates.

""Yes!""

The three of us left the kingdom immediately without getting noticed by the enemy, after running at high speeds for a minute, we finally arrived at the base camp.

"Both of you, hide somewhere for now. I'll explain the situation to you later."

I walked back to the camp, and saw the students sitting together in silence.

Nathia quickly noticed me and we walked to Lily and Vincent.

"Our job here is done, we will be going on ahead." I said to both of them.

"Yes, thank you for your assistance, this mission wouldn't be possible without the help from both of you, I heard it from our three royal knights. But, we have yet to give you your payment, please wait for a little bi-"

"We have already received the payment from the second prince, since we already fulfilled our job, it's time for us to go."

"I see, well then, thank you once again for your assistance."

After bidding farewell to the prince and princess, Nathia used another gem to teleport back first to Elune.

Meanwhile, I went to where Tanya and Kagami are hiding. Both of them stood up when they saw me approaching.

"Lucas-sama, we're joyful to see you alive again b-but how?"

"I didn't die, I was merely transported."

"So? what do you both plan to do now? we're not on Earth anymore, there is no Yggdrasil here, if both of you want to, there's no need to be my subordinate anymore. In this world, I'm just an ordinary royalty."

"What are you saying your majesty? we swore to be your companion until the day our life ends, just because we are on another world, doesn't mean our promise made on Earth is going to be broken." said Kagami.

"I see, then follow me. I'll take you to Elune." If we run at high speeds, we can arrive there within 1 hour.

"Is that where you're living now?"

"Yeah, now then, the sun will almost set, let's go."

""yes!""
