Oh, so they're changing EDs with every arc. Somehow I kinda expected something like that, but I would've liked Neko's ED for the full series. Or maybe this is just a special case for the Tatara episode, and it will go back to Neko next episode.
But shit, this was quite the change. Lots of backstory on Tatara and all of HOMRA, Shiro doesn't appear to exist anymore if at all and he has no idea what his real background is. I'm very curious to find out what this is all about. Also, Seri in street clothes is way more likeable.
