Well, lets see here. Hisa is the mysterious president of the mahjong club. Nodoka is the big breasted one so no surprise there. Saki is the main character with freakin awesome mahjong skills. And Yuuki is the short cutesy one and I think her power stands out more than Mako's. And there you have it. Mako is just that girl that wears glasses and is part of the club. I guess its because she hasn't done much in the series yet.. ＼（－－）／
Well, if you're talking about THE Sakiverse, then it's pretty obvious that it will be centered around mahjong. A spin-off of Saki without mahjong just won't be Saki anymore...
I thought about it being the possiblility of a guys version of Saki but....then it occured to me it would lose all that fanservice and yuri moments. -3-
I wanna know more about Hisa's past! It's still a mystery why her last name used to be Ueno.
hmm...I was hoping they would cover the nationals for individuals. In the original Saki, they only briefly mentioned a couple of new people unlike in the anime where they actually showed the matches.
If not that, then maybe more info on the unknown team Usuzan?
