Ako, Shizuno, and Nodoka were best friends in middle school, often going to Achiga Girls’ School to play Mahjong.  But as time passed, they saw each other less and less of each other.  That was until Shizuno saw Nodoka win the middle school Mahjong Singles tournament.  She is determined to meet her friend again, at the inter-high mahjong tournament!
Shizu really doesn't 
know how to calculate.
شيزو لا تفكِّر حقاً
Shizu de verdad no puede calcular...
Esta Shizu es que no piensa.
Shizu ne sait vraiment pas 
prendre du recul…
Shizu vive proprio sulle nuvole.
A Shizu não tem mesmo noção das coisas.
