Black (黒ブラック Burakku?): Shihai's Quirk allows him to merge his body into anything that is dark in color, whether naturally dark or dark via external circumstances, such as shadows. With further training, he can now move said black things upon possession, although this is limited to entities that are normally capable of moving. As such, he was able to merge into Fumikage's Dark Shadow and briefly take control over it to attack Fumikage.
