Yuuko loves trying to make other people laugh by making jokes (although they usually fail). She is usually undeterred by her joke failures and is quick to come up with new jokes, She is clumsy and takes a simple-minded approach to life. She isn't academically inclined, falls asleep in class, doesn't do with her homework and tends to fail tests. She is rather scatterbrained but very easygoing. She has a tendency to freeze when faced with unusual occurrences or circumstances.
