Machi background with yaichi

Spoiler for copy paste from someone:

Eight years before the series, she participated in an amateur Meijin tournament and made it to the semifinals, but lost to Ryou. Just when she was about to break down in tears, a young Yaichi told her not to cry because the moment one's heart breaks, that's the moment they truly lose. He then told her that he will show "an interesting shogi" to her and brilliantly won in the finals.

From that moment on, she already knew Yaichi is going to reach the top of the shogi world and devoted her entire life to become a female pro and a shogi reporter even if she realized she doesn't have any talent.
