FYI, Delima is the one among all member of Team J who ever be called "Hidden Monsters of Team J JKT48"
Even though, she has growth problem @ Pajama Drive setlist, it is still unknown why her progress @ Renai Kinshi Jourei setlist are considered the fastest. She has the ability to copy all of her partners skills in every unit songs, especially in Renai Kinshi Jourei unit song. And some of JKT48 fans also ever reminded Akicha to watch out this girl progress, if she don't want her center position at RKJ unit songs be taken from her.
