Yumekui Merry

Synopsis

As Isana leaves her guidance counseling session, she temporarily enters a daydream. Although Merry easily defeats Landsborough's henchmen, she is hesitant to attack him due to what Engi had told her. He then taunts Engi, explaining that if he is killed, then the dreams of his vessel will disappear as well. Engi attacks Landsborough out of anger, but Yumeji stops her and Landsborough escapes with his vessel. After calming down, Engi reveals what she knows about Mistleteinn, who has the power to force dream demons into vessels. Meanwhile, Chizuru, a vessel herself, confronts the guidance counselor, Ryouta Iijima, who is actually Mistleteinn's vessel, saying his next target is Isana who, at that time, Yumeji and Merry discover to have become a vessel.
