I like the idea of the book, yeah! As for armor, her skin is as durable as the other, naturally-ki-using characters. However, you could say she has weighted clothes that give her more AC.

AC stands for "Armor Class" and is equal to 10 + your DEX mod + any bonuses from armor or transformations. Whenever an attack is launched, the attacker rolls a 20-sided die (plus applicable modifiers) to see if it hits. If the result matches or exceeds the target's AC, the attack successfully connects. As it stands, because of her +3 DEX mod, Ruby's AC is 13. So if she had weighted training clothes, it'd give her another +2 AC at the cost of taking a -1 penalty to her DEX mod. So, a net increase of +1 AC.
