Synopsis: I transform into a beautiful girl. I have two identities: A soft, adorable catgirl, and a cool, alluring older-sister succubus. About the story: I was playing a free-roaming game. I fell asleep while customizing my character, and even kept doing it in my dreams. When I woke up, something unbelievable had happened. I had become the catgirl character I created in the game.
