At first I thought this was 12 eps long so I waited for all 12 to come out and marathon it, then I see in the subfolder that I have 15 eps now, gotta start watching soon or i'll be too far behind to watch it without crying how Chihaya overcomes the obstacles.
You can't really hate Chihaya at all, there is no way you can hate someone who is into a game for the sheer fun of playing it and who gets mad only at herself when she loses and not at the person that beat her.
Honesty is her greatest weapon even if it's a double bladed sword against her, she still menages to play and have the most fun out of it.
One thing bothers me, Chihaya doesn't have much say when it comes to her own competition, and her sister constantly tries to be the better one. Although that Quiz was funny

She deserved that :DD
It surprised me when Chihaya (and we) found out that her parents are compiling her own achievements as well.
That was so touching

And now that I marathoned the entire 15 eps, I'm ready for more !
Personally I do not think they can complete the entire story in 24 episodes, but that only depends on how they will do it.
RECAP !
D:
Chihaya should become classic literature teacher or something along that lane.
