I try mine.
Female, well I prefer Female for character besides if refer "rAthena" as a name, it's like a girl name, and if refers to "Athena" in Greek mythology, "She is Zeus daughter". And well, I want try collecting rAthena fangirls because his personality, not only fanboy because she's girl.
18, at this age, the average age of people still growth (like rAthena right now, still in development, endlessly) besides she will be cute young girl.
160 cm - 45 kg, average?
rAthena with nick rA, well just because I always use rA to call rAthena.
I try combined between: Athena as goddess of wisdom, courage, inspiration, civilization, law and justice, just warfare, mathematics, strength, strategy, the arts, crafts, and skill, rAthena goals, features, development, & community to make rAthena is person:She's a brave girl and kind of leader girl or want always to take a lead in group. She is person who always hears people thoughts & opinions, but as a girl she more likes any thoughts & opinion that she thinks praise her, and it makes she doesn't really like any thoughts & opinions that sounds criticism. In social, she never stops to gives new idea and innovations.
As a leader, she knows how to handle his group members, "like a water extinguish a fire" if there is compete argumentation, but this happen in her group, like or not, she will supports the argumentation that follows her idea, because she knows her knowledge, skill, and capability. But, if the conflicts between other group (like a competition), she will shows who's right and wrong, who's the winner and the loser! Even she maybe lose or wrong someday, I believe she will accepts it, because it's the truth and the fact.
She's good in exact sciences but not in non-exact sciences even she's good in analysis. She tried to be a strong girl, but one day she knows, she has strength limit, but her endurance is always better than other girl in her age, like she ever join football girl team (Soccer, America), but she never stands for a stage, but just need a bit rest (shorter time needed than her teammates) his stamina is back! (lol, is it a good story?)
Then, she never tries any sport that need much energy and strength, she tries in archery and plays chess with her older sister (guess who?) in her spare time as manga artist. Well, although she needs to repeat her drawings more than one times to finish it perfectly, the average is 2 repeats. But she ever made a worse repeat, one day, she thought her draws will finish in second attempt, but it was getting worse and made she repeat it until 4th attempt. But, even like that, she loves it, "Even I never finish it in first attempt, but it's a fun, and you know that people likes what I draw, and I like when I can "draw" a smile on people face." (she told me, haha).
Of course, as a girl, she is crazy in shopping! Every weekends, she spends it with her friends (who? ). She really loves accessory, such as rings, earrings, pendants, hairbands, & hair clips. Most of them are blue (light blue). But u know, her favorite is that hair band with that blue feathers, she always wears it on his left side (looks perfect with her dress, haha).
What else? maybe later.
