In the live-action series, Usagi differs slightly from her manga and anime counterparts. She is more outgoing and extroverted, and makes friends very easily. This immediately puts her personality in conflict with the other Sailor Soldiers, each of whom is solitary to some degree. She rarely uses formal grammar with those of 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 as if they are not friends. Every time a new Sailor Soldier appears, Usagi immediately tries to make friends, even though almost all of them resist. However, Usagi eventually makes the other Sailor Soldiers realize that they are stronger together than alone. Usagi also has a habit of forcing her interests on the people that she makes friends with. This is prominent in her relationship with Rei, where she repeatedly tries to get her to sing.
