The title is Shigeki, meaning stimulation. She goes to town in search of stimulation. This song is about that kind of mood. Have you ever experienced that feeling of being bored no matter what you do and feeling suffocated when you are alone? When you desperately want to talk to anyone to relieve the boredom, a girl will probably go out to the city. The reason she is so bored is probably because she has lost the meaning of life. She probably knows that she will never find an answer by wandering around the city. But she still goes out on the town because she can't hold on to her empty heart, and she is chasing a whimsical cat.
