I don't mean only National but more like big competition s in general (reply to Rika and Kaori beat her in the last b2 competitions.
Even a big fan, I always feel Satoko's vulnerable. Unbeatable, coming from you out of all people, is a big honour really!
Well she was pretty unbeatable by her team mates during two or even 3 seasons. I don't think she should have been unbeatable, but that was it.
