Saki
Sakia Lumei:The opposite of Saki she is a stubborn persona, she shows up when Saki is in danger to beat up her enemies. WOW!
Filament:She is the persona that isolates all of the pain that Saki cant bear, she know a lot of things that Saki dont know and help her friends with that knowledge
Selepetor:The big sis personality,for Saki that always tries to hide her feelings, she is the one who gives her all the advice about love. I have a high expectation for this one XD
Finnel
?????:A mysterious persona that rarely appears. She seeks to achieve her only objective that she remembers. My bet is this girl is Harvestasya
Souma:She is feared by people as the Clusternia's assassin, despite wearing a clown outfit her movements are very fast
Yurisika:Sorry cant read it but she seems to seek some kind of help from Aoto
