You couldn't fall asleep due to the uncomfortable grasp around your back. The grasp of the demon you knew as Koneko. Even in her sleep, Koneko constantly rubbed her face against your back, purring the entire time. Since you were still awake you heard the door to the room open and a young girl with black hair, purple eyes and red rimmed glasses tiptoe in.
You recognized her as Sona Sitri, the younger sister of the Maou Leviathan from the conversations before. She seemed to be looking for something, before laying her eyes upon you and frowning, for what reason, you don't know. Koneko had long since retired her Neko ears which means her hearing was reduced significantly compared to before. Sona walked towards you, quietly before whispering to you "I can get you out of being her possession. Just find me while you're alone and I'll tell you how"
Hearing these words filled you with joy! Escaping Koneko for good is blessing enough, but the pretty girl from before is the one saving you from her. If you couldn't fall asleep before, you definitely couldn't fall asleep now due to the jitters from hearing Sona's words. You stayed awake until the sun rose, still as energized as before, her words still echoing in your mind.
You felt Koneko's arms untangle themselves from you before you heard a yawn coming from behind you. You turned around to see Koneko stretching like a cat would, pushing her back in the air and all. Koneko looked around and then at you, remembering the events of yesterday and what she was aloud to do to you now. She gave off another large smile, hugging you again before letting go and jumping off the bed, walking over to her closet and pulling out clothes that were left for her. You, however, were forced to reuse the same clothes as yesterday because the Gremory's hadn't expected to have to supply for a boy as well.
You put on the plain clothes you were given from the jail before your execution and waited for Koneko, knowing that if you left before her she would get angry at you. Koneko finished putting on her clothes, which was a casual shirt with a casual skirt. All around casual. Koneko grabbed your hand and pulled you out forcefully, making you faceplant on the floor. Koneko continues to drag you across the floor, not caring about you falling and not exerting much strength either due to her recent strength gain.
You eventually manage to stand up again and thankfully, the floor outside your room is all smooth, nothing that would hurt being dragged across.
The question is, do you have an opportunity to find Sona and do you find her?
A: Koneko left you alone to do something with Rias and you successfully find Sona.
B: Koneko left you alone to do something with Rias, but you don't find Sona and maybe got caught.
C: Koneko never left you alone for the entire day, leaving you unable to reach Sona
