((It's a dark, stormy night. After having missed the last train home, you're trudging through the heavy rain when you spot a small, cardboard box, tucked away in the corner of an alleyway. To your surprise, the box holds a small, grey cat, soaked to the bone and shivering weakly. Not having the heart to leave the poor thing, you decide to bring it home with you and take care of it.))

After feeding the stray and giving it a bath, you decide to head to bed for the night. You're peacefully asleep when you're awakened by an unusual weight on your chest. Once you open your eyes, however, in the place of the little cat you'd expected was instead a sleeping cat girl!

— Mmrm... Nyaa... Don't leave me... Murmurs the mysteriously transformed stray.
