**In the Territory of the Phenex, in Riser's Private Mansion:**
Riser Phenex found himself in his majestic private mansion, surrounded by the distinctive aura of Phenex nobility. Yubelluna respectfully entered the room where Riser was immersed in his thoughts.
"Riser-sama," Yubelluna began, "your parents have accepted your decision to isolate yourself to prepare for the Rating Game. However, they are concerned about you fighting without the support of your Peerage."
Riser lifted his eyes from the chessboard in front of him, his confident expression not wavering. "Thank them for their concern, Yubelluna, but tell them I know very well what I'm doing.
Yubelluna, after receiving Riser's message, withdrew from the room with a graceful bow, ready to communicate to Lord and Lady Phenex Riser's firm decision.
Riser directed his gaze to Shizuku, who waited in a firm stance. "Keep an eye on the cameras you installed in Issei's room, Shizuku. We need to stay one step ahead."
Shizuku, moving a chess piece on the board, replied with determination: "Of course, Riser-sama. I'll be vigilant."
Riser, satisfied with Shizuku's response, turned his attention to another matter. "Is Erza still training?" he inquired, showing interest in the preparation of his newly summoned servant.
Shizuku, staying focused on the chessboard, confirmed: "Yes, master. She is in the training area, dedicated to enhancing her skills."

**Sona's POV:**
Serafall, with her lively expression, asked, "What's the matter, Sona-chan? Why did you want to talk to us?"
Sona sighed, displaying a somewhat resigned expression. "I was defeated in a chess game."
"What!!!" exclaimed Serafall, Lady Sitri, and Lord Sitri in unison, surprised by the unexpected news of Sona's defeat. Shock was evident on their faces as they processed the unexpected turn of events.
Sona, observing the reactions of her parents and Serafall, calmly explained, "I was visited by Riser Phenex, and he suggested a game of chess. However, he demonstrated surprising skill and won."
Lord Sitri, intrigued, questioned, "Riser Phenex? The heir of the Phenex House who is engaged to Rias Gremory? Why did he come to you?"
Sona shared the details of her encounter with Riser and his proposal for a Rating Game between him and Rias to decide the marriage contract. She also explained how Riser skillfully defeated her in the chess game, leaving her parents and Serafall surprised by the unexpected turn of events.
Lord Sitri, after pondering the information, lamented that the only one who managed to defeat Sona was about to get married. In response, Sona stated with composure, "I have no problem marrying Riser."
Serafall looked at Sona in panic, stammering, "Sona-chan, Riser is going to marry your best friend; that would be wrong."
Sona responded to Serafall's concern, telling the Phenex family that a marriage with a powerful family would be advantageous for them, and Riser will do what's best for his family. She added that, as far as she knew, Rias did not have a favorable opinion of Riser. Looking directly at Serafall, she said confidently, "You will help me, won't you, Onee-san?"
Serafall, who was worried about Riser, froze for a moment and remembered that the last time Sona asked her for something, Sona was still a child, which moved her emotionally. Serafall replied, "Yes, Sona-chan, no matter what I have to do. Even if I have to drag Riser tied to the altar, he will marry you."
Sona, somewhat irritated, said, "I just need your support; I'll handle the rest."
Serafall gave a shy smile and affirmed, "Alright, Sona-chan."

**In the Territory of the Phenex, in Riser's Private Mansion:**
Riser's POV
Riser was relaxed, receiving a shoulder massage from Yubelluna when Shizuku entered the room holding a tablet. Seeing her, Riser realized that something was wrong.
"Riser-sama, something happened in Issei's room," Shizuku said with a serious expression.
Riser, maintaining his usual calm, replied, "No need to get angry, Shizuku. I already expected something to happen."
He took the tablet from Shizuku and pressed play on the video she brought with her. The video revealed Rias Gremory, Riser's fiancée, teleporting naked to Issei's room and asking him to take her virginity. However, Grayfia appeared, argued with Rias, and took her away.
Riser watched the video without expressing much emotion, even though inside he was processing the situation. When the video ended, he kindly asked the girls to leave his room and go elsewhere.
Once Riser's Peerage members were gone, he turned to the system in his mind and said, "System, can you anonymously post this video on the DevilNet?"
The system promptly replied, "Yes, 300 points of luck."
