The group have a sit down chat with supervisor Satoda Mai, it's the first time for Funaki and Yanagawa.
When they talk about the experience of having new members join the group ( @4:20 ) Ozeki seems to not have such positive feelings about it. Is this CG 101?
^From certain talk shows and other instances, she seems to normally look like that. It could be another Eripon syndrome when people misunderstand her intentions/feelings. I think an Ozeki fan could probably answer better than me though, I don't follow her thread so this is just my opinion.
EtherSword has a point. Ozeki tends to keep quite among seniors. We usually forget that Ozeki is actually younger than Chisaki
Another good example would be an episode from The Girls Live's Musical Quiz where Ozeki was grouped together with super senpais Dawa and Sekki(UUG). She was very quite then too.
Come to think of it, maybe she just goes into that mode when she gets ask a question she doesn't know the answer too
Which is kinda adorable
