Alright, I added tags for: - Romulus-Quirinus (bottom-right corner; pose and theme make it obvious it's him) - Tai Gong Wang (left bottom-center) - Super Orion (top right corner) - Noah + Nemo (apparently the one who's raising the mug, based on twitter comments. Though, it makes sense, considering the theme. Wouldn't have figured that out myself, since I was thinking of girls, with Illya/Sitonai being the first one I thought of).
Related to that, I changed the tag from "2girls" to "1girl", since Altria now is the only girl in the group.
