AH!! I KNEW IT!
Halfway through the chapter, I had a feeling these two were Fushi's partners.
The very moment the room started to transform, I was sure of their connection.
I am sooo hyped for this arc. So much has changed, but in the end, it's still them!
Love that Eko can communicate with emojis now. Loved that they're still using the 3 knock signal from the siege battle days, excellent detail there. Seems Fushi is still alive and kicking, maybe even somewhere close by.
