A deep frown formed on Dr. Marshal's forehead as he heard the officer's words. His brows tightened, his shoulders stiffened, and for a moment, he simply stared at them as if their presence made no sense. From that expression alone, Shaan immediately understood one thing—Dr. Marshal clearly also had no idea why these officers came.

"Wait—hold on a minute. I don't understand what you're saying at all."

"The Twilight Sanctum Council will start a meeting to plan the Lunaris Revia event," the brown-haired officer explained. "Therefore, they sent us to gather all faction leaders."

"Oh, I see." Dr. Marshal nodded slightly. "However… it seems that I cannot go with you at this time. I will follow up later."

The black-haired officer widened his eyes at Dr. Marshal's response. "Dr. Marshal, why would you say that?"

"I still need to check several of my homunculi, and I must finish their inspections as soon as possible," Dr. Marshal explained. "My customers want fast service, and I don't want to disappoint them."

"Doctor, the council leader stated that this meeting includes crucial matters. Every faction leader must attend on time. That's why they sent us to bring each of you in person."

"...."

Before Dr. Marshal could respond, Shaan leaned closer and whispered, "Dr. Marshal, let me handle everything here. That meeting sounds important. You should go with them."

"Shaan, are you sure you can handle all of this by yourself?" Dr. Marshal glanced at him with doubt. "Checking every homunculus alone takes a long time and drains a lot of energy."

"I'm pretty sure." Shaan smiled with full confidence. "Besides, if I run into trouble, I can ask Mr. Courier, Nalira, or Chelsie for help. Don't worry about me."

"…All right then. If you say like that, I can resist." Dr. Marshal bent down and picked up a small orange folder lying near his tools. "This contains everything you need to check. Use it as a guide. If something confuses you, ask Courier 020. He knows the procedures well."

"I understand."

"I leave everything here to you, Shaan," Dr. Marshal said. "Please inform Courier 020 about this."

"I got it."

With that, Dr. Marshal let out a slow breath, nodded at the officers, and followed them walked away from the house. Shaan only watched as their silhouettes disappeared down the path, making the atmosphere quiet.

"Alright, now what should I check first—"

He froze. His forehead wrinkled deeper and deeper as he scanned the first line of text. Several unfamiliar words glared back at him—words he had never seen in his life.

"Catus? Membrum Superius?" Shaan scratched his head over and over. "What the heck is this? I don't understand any of these terms. I really need to find Mr. Courier. Right now."

He slammed the folder shut and rushed toward the lab. But as he stepped into the living room, he found Mr. Courier walking out of the lab with Nalira and Chelsie at his side.

"Ah—perfect timing!" Shaan hurried toward them. "I was just looking for you. Mr. Courier, I need your help."

"Help? What kind of help?" Mr courier looked around. "Where's Sir. Marshal? Wasn't he with you earlier?"

"Yeah, he was with me. But some members of the Council showed up and took him," Shaan explained. "The Twilight Sanctum leaders want to hold a meeting with the other faction heads to discuss the Lunaris Revia event."

"Ah, Lunaris Revia." Mr Courier stroked his chin. "That event is coming soon, and everyone needs proper preparation for it."

"Uhm... Shaan, what kind of help do you actually need?" Chelsie asked curiously. "Maybe we can help you."

Shaan immediately opened the folder again. "I wanted to help Dr. Marshal check the remaining homunculi. I tried to take the initiative but…" He scratched his head again, this time with a sheepish grin. "Everything written in here looks like… some alien language. I went completely blank."

"Shaan, let me see." Nalira took the folder gently from his hands. She skimmed the page once, her eyes steady. "Catus means 'head.' Membrum superius means 'arm.'"

"Correct. Miss Nalira explained it perfectly." The courier nodded with confidence. "Excellent memory, Miss Nalira."

"Wow, that's amazing," Shaan blinked. "I-I didn't expect Nalira to know something like that."

"They're Latin terms. Mr. Courier taught us all of this back in the lab."

"That's right!" Chelsie chimed in, nodding enthusiastically. "He's an excellent mentor. He explained everything to us in great detail."

"Interesting. I had no idea about that." Shaan nodded his head.

Mr Courier turned to him. "Shaan, you definitely need help with this." He shook his head lightly as he scanned the unfinished checklist. "I'll help. We need to finish the inspection quickly. We can't make the customer wait too long."

"I understand."

"... Elsie and I will help too."

"Membrum inferius means 'leg,'" Nalira recited.

"Arm, head, leg… got it," Shaan repeated each term quietly before marking the next box. "Check, check, and check." He placed the quill down and stretched his arms. "Ah—finally. Done at last."

A long breath escaped him. Honestly, he could not believe how difficult this simple-looking task turned out to be. He used to check flower stock at Isabelle's grandmother's shop—how could checking homunculus parts be so complicated in comparison?

"At least we finished everything," Shaan said, rolling his shoulders with relief. "Now we can finally relax for a—"

"No." Mr. Courier cut him off, his voice calm but firm. "We haven't finished our job yet."

Shaan stiffened. "W-what do you mean? Didn't we check everything?"

"We did," Mr. Courier replied. "But one customer wants two homunculi delivered to a specific location today." He flipped through a small note tucked inside the folder. "Here. Rosefield Residence. Inside the Twilight Sanctum."

"That's strange," Shaan muttered. A faint unease crawled up his spine. "Why would someone inside the Twilight Sanctum need two homonculi so urgently?"

"I don't know." Mr courier shrugged lightly. "But the customer specifically requested the homunculus you just repaired. And they want it delivered immediately."
