Age in anime and manga can be weird sometimes. From the differences in school systems, to the fact that the most popular genres are demographically for young people, to just art styles. Sailor Moon especially has its lead character and her team go through so much-it's hard to remember they are, mostly, just teenagers. And if you were wondering exactly how old each of the characters is, we've got you covered. Ami is the same age as Usagi, which makes sense because they go to the same school. There are no big changes in this regard. One of the biggest surprises I found when researching is that technically when we first meet Rei in act one of the manga she is 13 years old. But she quickly turns 14 a month later. The Japanese school year begins around April 1 and the manga confirms that Usagi is 14 at the start of the series. Usagi is a Cancer and her birthday is June 30th. Rei is an Aries and her birthday is April 17th. If Usagi is 14 when the series starts and the school year is in April early, then Rei hasn't turned 14 just yet. Sailor Jupiter is slightly older than the other Sailor Scouts due to her later birthday and halfway through the series would turn 15. Makoto has always seemed the most mature of the Scouts in terms of actual skills, as someone who is both an excellent fighter and cook. For bad-ass femmes, Makoto is an icon. In the anime, Makoto is made the same age as the other ladies.
Setsuna is the oldest of the main cast of ladies.
In the anime, as part of her goofy personality, she is the same age as Usagi. The Outer Sailor Scouts are older than our main group of ladies. Like her girlfriend, Michiru is also 16-17 throughout the series as a first-year high school student. Our youngest Sailor Scout! Hotaru is introduced as a 12/13years-old. Then after she is reborn she starts off as five years old, then ages up to 10 as her powers awaken. Despite her tiny stature, she is powerful. In the anime, Hotaru is initially 12 but then is transformed into 8-9-being reborn after Mistress Nine is removed from her. Setsuna is the oldest of the main cast of ladies. As Sailor Pluto, she is implied to be older than the fall of the Moon Kingdom, so centuries old. When she is reborn as Setsuna, she is 19-20 when she is reintroduced. Despite her small stature, due to the magic of the 30th century, she is actually over 900 years old. The reason she looks 8/9 is because she had not awakened her Sailor abilities. Once that happens she begins to slowly age. In the anime, Chibiusa is just a small child and doesn't grow in the same way, except when she is in scout form. One of the most controversial changes. In the manga, when we meet Mamoru, he is 16 and therefore only a year and a half/two years older than Usagi, depending on how it falls with their birthdays. For some reason, the anime decided to keep Usagi as 14-year-old, but aged Mamoru to 17. Because we know explicitly that Usagi is 14, it is just very jarring to see her dating a 17-year-old, even if it is only a year change from the manga. Those are the ages of the main characters of Sailor Moon. Not a ton of surprises, but at least you can find all their zodiac signs now.
Mia described her as someone who can confidently express her thoughts and feelings.
Scott Shelly ( Hangul:셸리 ) is one of the female protagonists in the webtoon. She begins a one-sided relationship with Jay at the start of the series but as the story progress they have a mutual crush on each other and as of chapter 378 they are in a relationship. Shelly is the only female member of the Humming Bird Crew. Because she stayed at England before coming to Korea her personality is perceived as very headstrong. She does not like it when people talk badly about her friends, especially Jay. Shelly also has a lot of stamina and strength, she can keep up with the group's pace when racing and can actually send people flying with her punch (Although that may be for comedic reasons) but never got into the street fights with the guys of the crew. When she was hit on in her first appearance on the series she refused with a lot of sass. Mia described her as someone who can confidently express her thoughts and feelings. Although her words are harsh, it is because she never sugar coated her words with her friends. And with Jay, Shelly is very clingy and flirtatious. She has very foreign features: pale skin, her eyes actually look more mint green in color than blue, blond wavy hair. It is known later in the series that she has a tattoo in the side of her arm near the wrist that reads out "temet nosce" or "Know Thyself". At school she wears her uniform usually without the red vest and both wears the skirt and pants.
Her second meeting with Jay was in their classroom.
She is often seen wearing high-end brand clothing, but also occasionally wearing street wear and tomboyish clothes. When riding her bike, she usually wears a jacket and helmet with the same color as her eyes or the Hummingbird crew's hood. She is tall, with long thin legs, a small waist and a bigger bust. Not much is known about Shelly, but it is established that she is from England and she requested to transfer to Sunny High School because of Jay. It was told in an early episode (Ep. 27) that she will be in Korea for one semester. Shelly is the granddaughter of Sunny High School's principal, Nick. When Shelly was a kid, she didn't want to get married and promised Nick that she will just live with him forever, which caused Nick to think that Shelly is not interested to guys until she got interested in Jay. That also caused the over protectiveness of her grandfather. Jay saw what happened and chased the thieves to get her purse back. She refused on taking him to the hospital but Jay refused. She picked up his student ID that had fallen to the ground and, motivated by her encounter with Jay, called her grandfather, asking him to let her attend Sunny High School. Her second meeting with Jay was in their classroom. She kissed him out of the blue and the gossip that Shelly and Jay were in a relationship quickly spread around the school.
When Jay, Dom and Minu got suspended, Shelly visited them and scolded Dom and Minu badly about how Jay got caught with their actions. Jay got pissed and told her to screw off, she ended up crying and running away. When Jay was about to say sorry, he got a pink rose from Minu, saying that he should give it to her. He couldn't and Shelly went on saying that she'll forgive him if he became her boyfriend for a week and Jay agreed. She joined Hummingbird as the only female on the team, she continued to flirt with Jay and when Jay was teaching Mia how to ride a bike, she kept on intervening and wanting him to teach her even though she knows how. On a special episode, Shelly was seen riding a bike in Jay's neighborhood. Minu and Kay noticed her, Kay was thinking of who might Shelly go out with and ended up being shocked that it was his brother. In the last scene, Jay and Shelly are resting after riding their bike together, and she comments that Jay suits biking more than studying. The Preliminaries for the League of Street has started, only Dom and Jay were able to race at the first two rounds. After that, they found out that Jay's birthday was near and planned to celebrate it. She didn't showed up at school on his birthday because she was the one who prepared the gift that they got for him.
Mia told her how she envied her for being able to confidently express her thoughts and feelings.
When the boys with the worried June except Jay planned to give Jay a strong alcoholic drink, they didn't expect Shelly to drink it, thinking it was juice. They are dumb-founded and later on, a drunk Shelly came closer to Jay and told her how she was hurt by his actions and proceeding to kiss him the second time. They pulled Shelly of Jay who was already littered with kiss marks. Mia was the one who brought Shelly home, when she was sober enough, Mia asked her if she liked Jay which she answered yes. Mia told her how she envied her for being able to confidently express her thoughts and feelings. Shelly answered that she doesn't understand Mia's concern and told her an advice to start believing in herself more and learning to love herself. This pushed Mia to contact the modeling agency that reached out to her. Before the race, Shelly was being hit on by a member of the Bullet Crew who will be racing against them. The glasses guy kept on hitting on her even when she's denying him. Vinny came to her rescue and punched the guy when he didn't stop.
That led to the glasses guy to take drugs to have a revenge against the Hummingbird Crew. Shelly took the lead until he passes the baton to June. As the race ended, she tried to kiss Jay in his sleep but he moved and she wasn't able to do so. She also took the test with Minu and Dom since, in a sense, she is still a student at Sunny High. When Mia was modeling, a bunch of girls kept on talking about her, gossiping about Mia like dating an old guy or having a sugar daddy to be able to model. Shelly obviously tried to help her. Yuna and Shelly later on went to Mia's house in hopes that they could get her to come to school. On the way riding a bus, a guy came up on her behind and was hitting on her, she shut him down while cursing, very contrasting of her appearance. When Yuna, Mia and Shelly were talking at the park near Mia's house, Shelly started saying something harsh to Mia, although it is a way to actually let Mia see what's happening beyond her room which she choose to lock herself with. Yuna reprimanded Shelly, saying she was too harsh and Mia broke down but then was silent at what Shelly said. After that talk, the three of them came at Heri's bike shop so that Mia can say thank you.
After that, she was asked by Minu, Dom and Jay to accompany Mia because she will be more comfortable knowing Shelly was around. She said that she did stay because she was told to but in truth, she came because she is worried, when Mia fought back with her bullies and was slapped, Yuna and Shelly came to her rescue. Shelly even tripped the girl who slapped Mia. And told Yuna and her that it seems like there's nothing to be worried about anymore. Which made Mia smile. Nick (Grandfather) - it is seen that her grandfather is very loving and protective of her. He was ecstatic when she called to say that she was moving to Korea. When she went to her first day of school at Sunny High he was seen outside her classroom being protective and calling her 'his sweet Shelly.' He perceived her as an innocent child who had no interest in boys, that is until she met Jay. This might be because of when Shelly was a child, she said to her grandfather that she will never get married and live forever with him. Shelly's Dad - The only time that Shelly's dad was mentioned was when she asked him to take her bike apart and send it to her in Korea.
Jay - Shelly was Jay's first and second kiss. It was quite clear from the start that Shelly harbors romantic feelings towards him. However, the same cannot be applied to Jay. He kept pushing and disregarding Shelly's flirting. He honestly seemed uncomfortable around her. After a few chapters, their relationship grows and they grew closer. Jay also became flustered after their second kiss, he turned off the television because it showed a kissing scene and he remains blank in school the next day. When Shelly shouted that she will give him another kiss, he dropped the ball that he was holding and looked shocked. When they are fighting a group of guys, Shelly came and Jay instantly shouted at her not to come close and go. There are many instances where it is shown that Jay does not mind when Shelly clings to him. When she talked about going back in Europe, he looked upset. In the third season, the story often focuses on their relationship.
Shelly was the one who found Jay in the mountains where the monk lives and where they trained before, he has to race with the monk so that Shelly could have her own room. Jay ends up sleeping in the same room as Mr. Nam and the monk. After getting frustrated with their loud (planned) snoring, he ends up leaving the room and walking into Shelly. They end up talking about returning and it was hinted at the end that Jay slept in Shelly's room, just like what Mario and the Monk planned. When the race started again, a guy from the team they are racing with flirted with Shelly, Jay came between them and asked them what they are doing. While in the race, one of the members of the opposing team pushed Shelly to get past them and that made her lost her balance, before she crashes on the ground, Jay moved beside her and helped her regain her balance. After the race, Shelly was on the phone, while Mia was talking to Jay, his focus shifted on Shelly to see what she is doing. When they are about to go home, Shelly accompanied Jay to his house, and when he was denied by his mother, she told her to come to her house and sleep there. They did nothing much, Shelly's asks him where he plans to sleep and he told her that he'll sleep in the sofa.
