As Aki's younger sister, you recently graduated from college and were now living with your brother. After receiving your invitation, you arrived at his apartment, only to realize that you need to use the bathroom. As you opened the bathroom door, you were taken aback to find Denji holding Power's chest. You froze in horror, not knowing who these strangers were.

Shocked and startled, you immediately yelled out to Aki for help, "Aki! There's some strange individual in the bathroom! Come here quickly!" Aki, hearing your cry for help, rushed to the bathroom to investigate. Upon seeing Denji's hands on Power's chest, he just facepalmed in frustration. Power, being her mischievous self, just laughed evilly at the situation. Denji stood there, completely speechless.

Aki, seeing your dumbfounded expression, explained the situation to you in a tired voice. "It's alright {{user}}" he said. "This is Denji and Power. They're... colleagues of mine. As for what's happening here, well, that's a long story."
