diff.text: Her journey begins when, while running to school, she sees some neighborhood kids abusing a cat and rescues it (in the manga she accidentally steps on the cat). Later, the cat comes into her room and reveals herself as a talking cat named [[Luna]], who serves as the [[wikipedia:Wise old man|mentor]] for the Sailor Moon. [[Luna]] gives Usagi a magical brooch which helps her transform into Sailor Moon (the "soldier for love and justice"), and tells her that she is a Soldier who must fight for peace. She also tells her that she must find the rest of the Soldiers, as well as their princess. Though at first Usagi is portrayed as a "reluctant heroine"<ref>Grigsby considers this reluctance to "substantially undermine the [[Agency (philosophy)|agency]] of the character", p.72 ; but [[wikipedia:Anne Allison|Anne Allison]] considers this to be one of the three key attributes of the series' appeal {{cite journal
diff.text: The dubbed version made Serena more of a ditz than Usagi, featuring for example lines such as "Hi, you look like da bomb in those kimonos",<ref>Episode 103</ref> which emulates stereotypical [[wikipedia:Valspeak|valley-girl usage]]. By contrast, in the following episode, Neo-Queen Serenity talks without this pseudo-valley girl dialect, showing this was intentional and inherent to the voice actress.<ref name=voicing>Serena was often made to whine and not control the modulation of her voice (compared to that of Neo Queen Serenity) rather than simply get louder. This can be compared best in the last few scenes of episode #125. Kotono Mitsuishi, Usagi's seiyuu, got louder, whereas the voice actresses for Serena get louder and then whined at the end.</ref>
diff.text: Usagi in the live-action series differs slightly from her manga and anime counterparts. She appears much more outgoing and extroverted, and seems to make friends very easily, which immediately puts her personality in conflict with her fellow Senshi, all of whom were loners to varying degrees. She rarely uses [[wikipedia:formal grammar|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 even 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.<ref>Pretty Guardian Sailor Moon, Act 5.</ref> Every time a new Senshi appears, Usagi immediately tries to make her a friend, even though almost all of them resist. However, through Usagi's influence, the other Senshi gradually begin to realize that they are stronger together than they are 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, when she tries time and time again to get her to sing.
