Disturbed Dreams - S1.E9

As Isana leaves her guidance counselling 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, saying that is 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 explains what she knows about Mystletainn, who has the power to force dream demons into vessels. Meanwhile, Chizuru, a vessel herself, confronts the guidance counseller, Ijima, who is actually Mystletainn's vessel, saying he plans to target Isana who, at that time, Yumeji and Merry discover to have become a vessel.
