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!
And why did you 
suddenly start sprinting?
لماذا بدأتُما بالركض؟
¿Por qué de repente aceleran tanto?
¿Por qué os ha dado por correr así de repente?
Pourquoi est-ce que vous sprintez,
 tout à coup ?
E poi com'è che stiamo correndo?
E por que vocês começaram a correr de repente?
