Reincarnated with an Analysis system.

Sato got down from the carrige, right in front of him was Vlad's mansion with lots of maids lined up at the entrance.

"Master, it looks like the Duke was already expecting you." Yuri commented, walking out of the carriage and standing beside Sato.

Sato responded, "Seems like it, Let's go." Before he continued his advance toward the entrance of the door.

Ignoring the maids, Sato and Yuri strolled inside the building, and as soon as they got inside, they were immediately met by Sebastian.

Sato arrived at the grand hall of the Nervek Castle, a massive structure made of white stone and adorned with intricate carvings. The hall was just as impressive, with high ceilings and elegant chandeliers hanging from above.

As Sato entered, Sebastian greeted him with a bow. "We've been expecting you, Lord Sato," he said, his voice echoing in the spacious hall.

Sato scanned the room, his eyes searching for any signs of the ceremony he was meant to attend. "Sebastian, correct me if I'm wrong, but isn't today supposed to be when I'm called out as the winner to all of Nervek?" he asked.

Duke Vlad answered instead. "There was a bit of a problem, so we had to reschedule," he said, a hint of regret in his voice. He walked down the steps to meet Sato, accompanied by his daughter, Erza.

Erza's face lit up when she saw Sato, but her joy was short-lived when she noticed Yuri, Sato's assistant, standing beside him. Her expression soured, and a hint of disappointment crossed her features.

"Duke," Sato greeted Vlad, bowing his head in respect.

"Who's the beautiful girl you have beside you?" Vlad blurted out, his eyes fixed on Yuri.

Sato's eyebrows furrowed in confusion. "I believe you've met her before, she's my assistant, Yuri," he said.

Vlad let out a hearty laugh. "At such a young age, I'm proud of you. You might surpass me at this rate," he said, still chuckling.

Sato gave a nervous chuckle in response, not quite sure what Vlad meant.

While Vlad and Sato exchanged pleasantries, Erza beckoned Yuri to follow her. "Yuri, we need to talk," she said, her tone serious.

Sato and Vlad exchanged a puzzled look as the two women left the room.

"Oi, did you mess up your harem?" Vlad whispered to Sato, a mischievous glint in his eye.

Sato's face fell, and he shot Vlad a deadpan look. "Please stop saying such perverted things," he said.

Vlad let out a boisterous laugh. "Anyways… Come with me, I think it's time we discussed," he said, gesturing towards the stairs that led to his private chambers.

Sato let out a sigh, glancing at Sebastian, who avoided his gaze. Another sigh escaped him before he followed Vlad up the stairs.

…

They made thier way toward the room, both the Duke of Nervek and lord of Elves, sat down on the chair, facing one another with a giant map steated on the center table.

Beside Erza were two soliders, first was Veronica Valdezi, the second leader of the forever knights, and the second was the commander, Selvin.

Sato sat down, looking at the map and was quick to notice the naming on them, from that, he knew it was a map of Fiona.

"I'm sure you've figured it out already." Vlad said, observing as Sato's eyes were reading the whole map.

"You want to discuss the war against Fiona?" Sato asked.

"Right on the head." Vlad voiced out, "As I said, I am willing to help you win this war, but I'm still under the Demon's lord's rules, so my actions will be limited".

"About that, I never really explained the full reason why I accepted the war in the first place." Sato hinted.

Vlad leaned forward and asked, " Was it but because you wanted to protect the forest?".

"That is part of it." Sato responded, "Another reason is, I want to merge Nervek together with the forest and turn it into a nation… and for that to have a chance…".

"You plan to use the war as a means to corner the kings and let him accept your demands,.." Vlad completed Sato's words.

"Exactly," Sato uttered with a smile on his face as he also leaned forward, "I'll split Nervek from Fiona and link it up with the forest".

"Not a bad idea." Vlad said with an evil grin on his face.

"I knew you'd understand." Sato said back, grinning as he looks Vlad in the eye.

…..

Yuri and Erza were in Erza's room, with Yuri standing at the entrance while Erza sat on the bed. The room was quiet except for the soft sound of their breathing. Yuri was wondering what could be so important that Erza would drag her away from her master.

"What is it you wanted to tell me?" Yuri asked, her tone curious yet serious.

Erza took a deep breath, her hands gripping the edge of the bed. "I want you to teach me how to use magic," she said, her voice steady despite the nervousness she felt.

Yuri raised an eyebrow in surprise. Vampires were known for their innate ability to use magic, and as a royal vampire, Erza was expected to be a master of all types of magic. So why did she need Yuri's help?

"Do you have a problem with that?" Erza asked, meeting Yuri's gaze with a determined look.

Yuri let out a sigh before responding. "No, I don't have a problem with it. What kind of magic do you want to learn?" she asked, her curiosity piqued.

Erza stood up from the bed and walked over to the drawer beside her, pulling out a thick book and laying it on the bed. "I want you to teach me summoning magic," she said, looking up at Yuri with a serious expression

Yuri moved closer and picked up the book, looking closely at it but she still couldn't tell what the book was about…. "What is this?" Yuri asked.

"It's a summoner book, belonging to my mother." Erza replied, "Inside the book holds different kinds of celestial spirits… I want to be able to control them at will".

"So, what do you say, can you teach me?" Erza asked.

Yuri opened the book and began flipping the pages to see drawings of different spirits. She closed the book and responded with a smile on her face, "Sure, why not… I'll teach you".
