There will be quite a few characters, but 2 of them will be more important. The main protagonist is called Derek. He's a young adult (18-21 yrs old), and he's an orphan. He lives alone in an industrial city and he works in an eletronics shop as a mecano. The owner of the shop has became his second father over time.
Derek's parent have been killed 10 years ago during war against an enemy empire.
As for his personality, even though he may appear so, he doesn't like adventure much and he likes his current life. He is not one who likes change.
The other main character is a female one, Lucia. She is also a young adult though she's a bit older than Derek. She does not appear in the story at first, but only later. Without getting into too much detail, she's part of a secret society which goal is to prevent war between different nations. She is very confident and competent, though she may appear to have a cold temperament from time to time.
Here's a quick sketch I did yesterday, their appearance is not set into stone tho. And these are just random costumes.
