Name Description Image
Sound Control Motoki has the ability to control sound and uses it for eavesdropping and for scouting. He also possesses a strange pill that increases his ability and allows him to perform even greater supernatural abilities, such as propelling himself into the air. Using more than one pill allows him to create a sound clone of himself and control it by concentrating while wearing his headphones. What this clone is capable of doing is currently unclear as it was destroyed quickly by Dimitrie Vatler. Motoki
Soundscape By using his headphones he is able to enhance his hearing beyond that of a normal human. He is able to use this ability to spy on others or to keep tabs on them. The weakness of Soundscape is that it is too sensitive, a powerful burst from Kojou Akatsuki when he was injured by Kirasaka Sayaka disrupted the Soundscape and harmed Motoki's hearing for several minutes.
