I guess I was hearing right, it's Yoi (there is a - over the o).
Baking powder? I don't think I've heard that particular term before so maybe it's specific to the show.
I just finished
Night Raid - 1931. It was a nice show and the photography hook certainly resonated with me. The "extra" episode (not the second OAV episode) was inexplicable. It was a half-synopsis of the show, nothing more. Odd.
Now I can get back to the final disk of
Ceres, Celestial Legend. Thus far it's been a soapish emo-fest and I don't anticipate the rest being any different. It's been an entertaining watch but I find that I'm still annoyed when the "nice guy" loses to the brooding "emo guy" (yet again).
