Teacher Jessica was a beautiful young lady, around twenty five years of age and single. She was an orphan when she was a child and had been trained in the same Elemental Tree in the past. Despite being so young, she possessed amazing skills and had been recognized as an experienced adventurer. Thus, the school now hired her to become a teacher and she was actually one of the youngest.

However, teacher Jessica rarely came to school. That was because her workplace was inside the dungeon areas. After the students had their lessons at school, they would then be sent to have dungeon field trips and Jessica would be the one who guided them. She was the best suited for this because of her jobs: Trap-master, Spy and most interestingly, Cartographer.

Inside the Greentrees Forest, old dungeons or new dungeons, Jessica knew about them all just like the inside of her palm, and it was actually the first time she met the kids.

...

But she was also hiding a terrifying secret.

Jessica was meditating, or at least, looked like she was meditating.

“Lord Diaminos (sama), I want to report,” Jessica thought to herself during the short thirty minutes rest. Nobody else could hear her, except for the one named Diaminos.

“Jessica,” a deep voice answered right after that, “how’s everything?”

“I’ve met the kids, all seven of them. I will bring them to you shortly,” Jessica then said.

“Good. Are they in good conditions?” asked Diaminos.

“Yes, I believe. All the kids are perfectly healthy and have excellent abilities. One of them even has a second-tier job,” Jessica replied.

“Very good. Then they will make the perfect vessels.”

“Yes. However…” Jessica hesitated to speak of something.

“What is it?” Diaminos asked.

“No, I’m just worrying too much. Please don’t mind me…”

“SPEAK!” Diaminos suddenly raised his voice

“Y-yes! There’s this teacher… I wasn’t expecting him to come at all! I thought I'm the only one in charge of this field trip...”

“Hmmm, so he’s in the way.”

“What should I do, Lord Diaminos?” Jessica asked, worriedly.

“Get rid of him.”

“I afraid... I can’t,” Jessica replied “He is... very strong.”

“Is that so? His status?”

“I'm sorry. I can’t see it with my Spying skills. He must has some kind of Concealment… And I have a feeling that he might know something…”

“But it’s only him?”

“Ah… yes, only him, no one else.”

“Hmmmm…” Diaminos then thought for a moment. “So what race is he? Is he an Elf?”

“No...”

“Angel?”

“No…”

“Then what?”

“He’s just... a human”

“A HUMAN?” Diaminos raised his voice again!

“Y-yes!”

“A MERE HUMAN!? AND YOU THINK WE SHOULD BE AFRAID OF HIM?”

“No, I just…”

“WHO DO YOU THINK I AM!?”

“No… I…”

“Haha! Jessica!” Diaminos burst out laughing inside Jessica’s head. “Then what is the problem? Just bring them all here! Or don’t tell me… you are planning to betray us!?”

“No my Lord! No! My apologies, I was just too nervous! I will bring the kids to you right away!”

“Good! Then I will be waiting. The ritual will soon be started.”
