(Quirk) Dark Shadow (黒影ダークシャドウ Dāku Shadō?): Dark Shadow is always connected to Fumikage's body through an "umbilical cord" (as described by Shihai Kuroiro), even when it moves far away from him. However, Fumikage does not appear to share the same physical sensations as Dark Shadow, such as pain and weakness, or vice-versa, meaning that incapacitating just one of them will not prevent the other from acting out. It is somehow able to communicate with Fumikage telepathically, as well.
