Spoiler for Preview summary for episode 4:
"Distressed girls"
The transfer student who has the same face as Hecate, Konoe Fumina, grows accustomed to school life with the support of her kind classmates. She eats lunch with Shana, Yoshida, Yuuji, and Ogata. But it isn't like their doubt on her has disappeared.
Margery and Wilhemina look out for suspicious things, without watching for the movement of the Bal Masque from the Flame Hazes around the world. (I don't understand/can't translate this statement, but it has something to do with those two preparing for anything suspicious).
Knowing or not knowing it, Yuuji invites everyone to a newly opened restauraunt. Then, while Yuuji and Satou are having a ramen-eating contest, Fumina disappears.
Spoiler for images:
They're looking at something...
Soaked Fumina...
Probably cleaning the pool
Oh no! Cliffhanging summary!
Stupid Yuuji...
