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!
The reason we haven't 
seen any dora is because
...لم نرَ أي دورا
La razón por la cual no has 
visto ni un dora hasta ahora
Si no has visto ningún dora
Kuro n’a jamais 
laissé voir sa main,
La ragione per cui 
non si è ancora visto nessun dora
Você não viu nenhum dora até agora
