Looks like Eri was enjoying herself during the recording! (:
Eri's answer : When I have to ask my juniors to help me massage my shoulders.
Eri : My shoulders stiffen very frequently so I often have to ask the 8th generation member, Mitsui Aika-chan to help me massage them...when she is free.
I hope Eri takes good care of herself. She is only 20 x.x Its worrying to hear that she's getting stiff shoulders already.
