It's pretty hard to explain, but I'll try my best! Anastasia is whatever Zhenya says it is, his greatest source of strength and his weakness, a 'weapon' that makes him the most powerful man in the world. That's why you can look at Anastasia as an actual weapon, but also as Taekjoo, because Zhenya calls him that at one point:)

I Haven't read the manhua yet but im curious to know What exactly anastasia is !? Is it a person a thing or what??? Ive been losing it ever since I heard that one specific cd segment of Zehnya speaking about it and I wanna know desperately
