Maria-sama ga Miteru episode 5

The problem is getting worse.

Yumi thinks that one of the Roses has been slapped.

Yoshino, the girl who returned her rosary, thus starting off the entire problem, is in the hospital. She has a heart problem and will have to have surgery.

Apparently Yumi isn't the only one with an inferiority complex.

The surgery works and Rei visits Yoshino and they talk.

Yoshino once again becomes Rei's souer and other girls who had returned their rosaries end up doing the same kind of thing with their old "older sisters."
