Or the other way around. Since Soowon has his illnes and Hak is the more active on the battlefields cariing out orders an such? I mean I get it that he protects Yona, but I would say that the brain is the shield(Soowon) and the beast is the sword. Since both of them are protecting Yona according to the phropecy anyway.(⌒▽⌒)
I think there’s a very big chance it’ll be like this, but I also entertain the thought of Zeno being the shield and Yona being the sword herself. I remember Ik-soo said something about it being too early for the sword to appear yet (which could mean that Soowon wasn’t ready to become her sword yet, but idk, sounds a bit off to me) but idk i need to go back and read the prophecy again because I don’t remember if there’s something that invalidates Yona being the sword herself.
Lads; the sword probably soo-won, and shield most likely hak.
