Buff Sei sure got buff. I would've thought that Sei would have at least built muscle mass around his arms and legs, but the guy has the six-pack.
How to get abs like that? What's his weird trick?
@Ominous Abbs are shown when you have little to no body fat or sufficiently dehydrated for them to show. Considering even when they have food, he's been constantly moving, his body is that of a prison innmate.
I'm glad Sei has finally decided he cares about everything around him. So many fewer people would have died if he'd managed to have that realization earlier.
