Others have mentioned that she drank alcohol, it was Yamada who only drank Cola, but the other part is also wrong: it is a tight fitting shirt/undergarment, since she isn't supposed to be naked in the scene (or else she would probably be having a bigger reaction). I sympathise with the sentiment about age rating uncertainty though, as the other replier (icam98) said, shojo (and shounen) can cast a pretty wide net in the sort of stuff they can depict.gets drunk off of cola
censorship that kinda looks like a super black tight fitting shirt
Anyone else feeling like this series isn't quite sure what age demographic its going for?
