Yume-chan and the others try to save Aoi-sensei, who is in trouble because of Yuni's Black Abyss, with Yume Synchro. However, I was unable to purify the Black Abyss with my Mykle Stick... This is the first time this has happened. Aoi-sensei couldn't help either... at this rate, it's going to be tough! At that time, I found out that the owner of another Dreamy Mate was "that person" close to me...
