diff.text: '''Usagi Tsukino''', (known as Serena in the English dub) is one of the original five Sailor Senshi [[sailor soldiers]] and is the main character of [[Naoko Takeuchi]]'s [[Sailor Moon]] series. Within the series, Usagi Tsukino is introduced as a schoolgirl living in 20th century Tokyo. She is initially depicted as a well-intentioned but underachieving crybaby who prefers the life of a normal teenage Earth girl. Nevertheless, she continues to fight the evils of her past life and protects the Earth with the Silver Crystal, as the Champion of Justice, Sailor Moon, which provides for most of the conflict within both the manga and the anime.
diff.text: She is a poor student, and often comes off as dumb (especially in the anime), though this is generally played off as being due to naïveté and laziness rather than actual stupidity. This is because she spends her time eating, playing video games and reading comics (including RunRun, which published the Sailor V manga in real life) rather than studying.[citation needed] She is often portrayed as a character that is better at art than science, as with her inability to answer that apples fall from trees because of gravity.
