What are the translation of these two tanzaku in Date A Live II OVA?
Initially, Kotori wrote in her tanzaku


  士道と結婚．．．


I don't know what lies beyond the cut off part, but it can be inferred that she wants to get married (結婚) with Shidou.



As for Kurumi's tanzaku, it reads


  士道さんとまたいつか会えますように


which translates to


  I hope to meet Shidou-san again some day.


If you are wondering, the last 3 characters on the bottom left corner is her name [時崎]{ときさき}　狂{くるみ} (Tokisaki Kurumi).
