her age (though she does with adults), and refers to everyone as "given name-chan" (which is very informal and a way of expressing closeness). She teases Ami when Ami continues calling her "Tsukino-san" (a formal way of speaking to classmates), saying that it is like they are not friends. Every time a new Sailor Guardian appears, Usagi immediately tries to befriend them, even though almost all of them resist. However, Usagi eventually makes the other Sailor Guardians realize that they are stronger together than alone. Usagi also has a habit of forcing her interests on her new friends.
