I had a bit of trouble finding a suitable candidate, Libras strives to create equilibrium in all areas of life much like the scales it represents not to mention that I myself am a Libra. Then I remembered a character of whom I also share a birthday with, Super Sonico.
Why Super Sonico against some pretty impressive characters?
Just to count down what she does in her life, she's a musician, a model, a spokeswoman for video games as well as playing them, a cosplayer, a university student studying Marine Biology so we can add environmentalist as well as training in lecturering in the subject and owns an entire litter of cats who also function as her alarm clock, that's just the anime, what she does in any of Nitroplus' promotions is endless, achieving equilibrium in all areas is exactly what Super Sonico achieves everyday.
