My confusion came from me interpreting that character's design as distinctly male, where this voice is effeminate where I thought a boisterous male voice would be. That's fine, it just caught me off guard.

Now we're in the thick of the character and world building that makes me enjoy this so. Captains are all monsters we can look forward to meeting (along with their other squads). Some sinister framing makes us question alliances of characters. A(nother) formal villain faction. Yachio is given some redemption and plans are in motion to go on the offensive; I prefer an active to a reactive cast in this type of setting. And they still fit in some fanservice.
