I hope they will bring more new players to the list this year.
Nanami Hirose (廣瀬七海) can try to replace Nagaoka. She is good at attack as well.
Nanami Seki (関菜々巳) should get a chance to play for National team. I think her set is good with very high quality to outside hitters.
Mai Irisawa (入澤まい) also can be tested in international competitions.
There is few potential outside spikers in Japan as they are very short and V League is not most competitive. But still worth to try some new players to see their performance.
