Chapter 3

Three years had passed since Sona and Rias had left for the human world. During this time, I had risen to the top three in the rating game rankings. My fighting style, characterized by wearing armor and wielding a lance, earned me the nickname "Undefeated Knight Princess" because I had never been defeated in a rating game, even against opponents like Roygun Belphegor, ranked second in the ratings, whose bloodline magic was ineffective against me.

Now, it was time for me to join Rias and Sona in the human world. Standing in front of the Leraje family's mansion were my parents, the Sitri couple, and Serafall.

"Bia-chan, please take care of Sona while you're in the human world," Serafall said to me, using her nickname for me.

"Of course, Sera-nee," I replied with a smile.

"Be careful out there. Even though you're strong, it's important to be cautious," my mother advised.

"Just like Sera said, please take care of our child, Bianka-chan," the Sitri couple echoed Serafall's sentiment.

After bidding farewell, Rita and I used teleportation magic to arrive in the human world. Among my peerage members, only Rita accompanied me, as the others were occupied with various tasks or simply uninterested.

We appeared in front of the large mansion that my father had prepared.

In Kuoh Academy's ORC club room, Rias and Sona, along with their peerage members, were present.

"So, Sona, why have you come here?" Rias inquired.

"I've come to introduce my new peerage member. His name is Saji Genshirou," Sona replied.

"Nice to meet you, Gremory-sama! My name is Saji Genshirou," the young man greeted.

"Ara~ He's quite enthusiastic," Akeno remarked.

"Hey, Kiba, isn't the President also a devil?" Issei asked.

"Um, yes. The President, like Buchou, is a devil and the heiress to the noble demon house of Sitri, as well as the younger sister of the current Satan Leviathan," Kiba explained.

"What?!" Issei was surprised to learn that there were two devil heiresses attending his school.

"Nice to meet you too. My name is Rias Gremory," Rias introduced herself.

"So, Rias, will this new pawn be your trump card in your engagement?" Sona inquired.

Rias's expression darkened. "I don't know, Sona, but I've heard they might accelerate my engagement," she replied, biting her lower lip.

Sona was about to leave the club room when a magic circle bearing the Sitri clan's crest appeared.

From the magic circle emerged a handsome man with black hair and blue eyes, Sona's father, Drian.

"Good afternoon, Rias-chan and Sona-chan," Drian greeted them with a gentle smile.

After exchanging pleasantries, Drian conveyed the news that Bianka and Rita would also be attending Kuoh Academy starting the next day.

"Really, Otou-sama?!" Sona exclaimed excitedly.

"Yes, they arrived at their mansion in the human world today. I believe Bianka will come to obtain her transfer documents from you," Drian confirmed.

"Okay, I'll leave immediately. Like I mentioned earlier, I'm quite busy at the moment," Drian said before bidding farewell and disappearing along with the magic circle.

Back at Kuoh Academy, Saji asked Sona about Bianka, curious about her sudden excitement.

Before Sona could respond, Akeno provided an explanation about Bianka, detailing her prowess and accomplishments in the underworld, including her title as the "Undefeated Knight Princess."

Everyone in the room was surprised to learn about Bianka's strength and reputation.

"But I didn't expect Bianka-sama to come to the human world," Akeno remarked.

"Yeah, neither did I," Rias admitted, still lost in thought about Bianka, whom she admired greatly for both her strength and noble temperament.

"Mn... I can't wait to taste Bianka-sama's cake again," Koneko said with her usual expressionless face, though her eyes betrayed her excitement.

With that, Sona bid farewell to Rias and her group as she needed to take care of Bianka's transfer documents.
