I'm not sure if she was injured but she was not rostered at all in the final 14 per game, so I assume yes. She could've helped in some of their games last season, when both SWP and Hirose are not performing well. She can take the spot of Hirose as the first sub for SWP. I love watching Furuya's strong attacks but still inconsistent, and her floor defense is bad.
Furuya was like a BCS in Uni. Kind of turned me off on her and she's never recovered. She's a firecracker, tho, for sure, and as you say, inconsistent. Unless she splits NEC I think she'll never be anything more than a dub-subber, occasional player
The thing I like about her most is that all her team mates seem to really like her, would pick her to be with if they were on a deserted island
I was also disappointed with Kawakami. Her softness is her strength until it prevents her from doing anything
