Merlin is an accomplice of Sora and Nike. She is seen on the aircraft confronting Kanon and the others after they arrive. She attacks Kanon with a move similar to his sound waves. She is later seen with Morrigan, who begs her to kill her for losing to Benkei. Merlin later watches the escape craft with Minami and Rika take off.
Merlin appears to ride a similar road to Kanon's Ring Road as seen in Chapter 284 where she attacks Kanon with a move similar to his sound waves. Not much else is known about what road she rides.
