Dear Ninjas,

Thank you for quickly providing us with information which helped to quickly solve this issue.
The Mystery Skills for Sasuke, Gaara, Anko and Haku have all been fixed. During the weekly update,the art for these units' Mystery Skill was updated; a problem with the coding of the source of this new art and the previous one occurred during the process.
We are sorry for any inconvenience.

Thank you,
Naruto Online Operation Team
