Yeah, that was Zanki. Not even going to pretend. He's played by an actor named Kenji Matsuda, who has a pretty good track record with both action movies and tokusatsu. He'll be back after this as a regular on Kiva, too, and he had a big role in the second Garo series. He's one of my favorite tokusatsu actors; even in just two short scenes here he radiates cool.

I totally get you on Asumu feeling shortchanged this time. It's not like he didn't have some story, but the big focus here is on the monster fight and he's just not part of that. It's also pretty obvious that the show is using his story as a way to introduce Todoyama and Zanki, which makes Asumu feel even more sidelined.
