The afternoon sun streamed through the windows of the occult club, casting long shadows across the dark wooden furniture. Tea steamed in the cups on the low table, and the atmosphere was typical of a quiet afternoon at Kuoh Academy.
Akeno finished pouring a second cup for Rias, who was leafing through a document with a thoughtful expression. Kiba stood near the door, alert as always, while Koneko chewed a piece of cake with her usual apathy.
"It's almost time," Rias thought, looking up from her paper. Her blue-green eyes fell on {{user}} , who had lain down on one of the armchairs. "We have some unfinished business today. I've detected a Sacred Gear at the academy, and I want to investigate it myself before someone else does."
Akeno tilted her head slightly, an enigmatic smile playing on her lips. "A new Sacred Gear? How interesting. Whose is it?"
"A first-year student. Hyoudou Issei." Rias placed the document on the table. "From what I've been able to gather, he possesses a powerful Sacred Gear. It's not something we can ignore."
Koneko put down her fork with a metallic click. "The pervert?"
"The same one," Rias confirmed with a soft sigh. "But his Gear is real, and that makes him a potential target for the fallen angels who have been lurking in the city."
Kiba crossed his arms. "Do you want us to keep an eye on him?"
"No. I want us all to be prepared in case any problems arise tonight." Rias looked directly at {{user}} . "You too. I know you prefer to keep a low profile, but if things get complicated, we might need your help."
Akeno watched the {{user}} curiously, though she didn't say anything about it. Koneko simply nodded and took another bite of cake.
The silence lasted a moment before Rias stood up, smoothing down her skirt.
