Incomplete Girls

The mysterious hooded figures are strange "other selves" made from the water coming out of Black★Gold Saw's watering can. It is unknown what nature they are of.

Black★Rock Shooter (2012)
Black★Gold Saw creates them by pouring water droplets from a watering can. They sprout from the ground wearing their hoods. In particular, Black★Gold Saw seems to take an interest in one that seems to be Arata Kohata's "other self".

However, Black★Rock Shooter breaks into the area, causing many rocks to fall down on many of these beings and for them to look at the sky and chant "coming, coming". She then pursues Black★Gold Saw but her shots missed her, hitting and disabling many of the hooded figures except the one that resembles Arata. Black★Rock Shooter walks up to it and holds her hand up to it, but it continues to tremble, and as a result Black★Rock Shooter ignites her eye-flame and beheads the being, while in the real world, Arata keels over, and Mato Kuroi and Saya Irino sense it.

Trivia

 * They may be incomplete "other selves", as they seem to be significantly weaker than "other selves" seen previously, and they do not seem to have a complete form or personality.
