Could this be foreshadowing?
Shuri's name was changed to Gunko. On one hand this could be symbolic of her personality change (and bestowed by imu) and on the other hand it was symbolic to give her a "royal" name instead of the lower realm one (given by Manmayer family). However, shanks and shamrock retained their names.. garling never changed theirs.. could this be because their personality was intact when Imu was around? Or CDs really donbcare about names..?
