Here is my introduction to my SU Gemsona, Jade.
Even though her bio can be found on the image itself, here is her backstory and some facts about her, too.
OK, let's start with her backstory.
Jade is a born genius with great knowledge for science and mathematics. Having such intelligence, she tends to find the solution to the problem and is usually the one who comes up with new ideas. Havin such technological skills, she fixes vehicles and electronic devices all by herself and is keen on solving algorithms. However, she can also be a bit adventurous and energetic, and can hardly be injured.
