Other self

An "other self" is an alternate counterpart to a human character that resides in the Otherworld. Very little is known about them, but it is presumed that huke's characters are of this type.

Black★Rock Shooter (OVA)


An "other self" has some sort of connection or personality similar to that of their human counterpart. When their goals become the same, presumably the "other selves" can create a connection to their counterpart and make a deal with him/her to "merge" or "fuse". The only people who have been seen to do this are Kuroi Mato and her "other self" Black★Rock Shooter, but it can be assumed Takanashi Yomi and the Dead Master did the same as well.

It is possible that an "other self" cannot even materialize without merging or taking a body, as Black★Rock Shooter's lips do not move when she talks before she merges, and the Dead Master dissolves immediately upon leaving Yomi's body. However, this may be because Black★Rock Shooter could be dead (it is possible Black★Gold Saw killed her instead of just giving her scars).

How much control each party has when merged is also unknown. When merged/possessing Yomi, the Dead Master was behaving in a violent, cruel manner, much unlike Yomi; however, it is possible Yomi had lost control or was sharing the Dead Master's angry instincts. However, Black★Rock Shooter seemed to be empathetically reacting to the Dead Master/Yomi in a way Mato would be likely to.

It is also unknown whether there are beings other than "other selves" in the Otherworld; for instance, whom Strength or Black★Gold Saw would correspond to is unknown (although Strength is implied to be the "other self" of Yuu). It is unknown if Black★Gold Saw is an "other self" at all, and if she is, whom she is one for and how she relates to Black★Rock Shooter or Kuroi Mato.



Visual cues that an "other self" is one to a human counterpart is similar eye color (Mato and Black★Rock Shooter both have blue eyes, and Yomi and the Dead Master green) and similar hairstyle (Mato and Black★Rock Shooter's pigtails and bangs, Yomi and the Dead Master's halfcut). These cues imply Strength to be an "other self to Yuu, as both have the same choppy hairstyle and hazel eyes. In addition, there is a girl on the train (unrelated to Mato in any way) in the beginning of the OVA with a similar hairstyle (although the eye color is unclear) to Black★Gold Saw's, making her Black★Gold Saw's possible human counterpart.

Black★Rock Shooter (Anime)
In addition to Black★Rock Shooter, a new "other self" is introduced named Chariot. Not only does she look almost identical to Kagari, she is seen throwing macaroons (a favorite food of Kagari's) at B★RS, and waves her hand to Kagari's chant of "Go away!".

Dead Master is seen again, and she has glasses similar to Yomi's. Her cry of "help me" resounds as Yomi goes through Kagari's torture, and she has the same scar on her chest that Kagari inflicts on Yomi.

Saya Irino implies that there is someone out there who takes a person's pain from their hearts so that they will never feel physical pain when the are hurt. The "other selves" are implied to be this, as Black★Rock Shooter is seen screaming in pain while Mato goes through emotional turmoil. "Other selves" seem to be rather resilient, as Black★Rock Shooter sustains many injuries that would be mortal on a human being.

Eventually, Yuu Koutari reveals to Mato that these beings have essentially taken on the grief of each counterpart in the real world, but killing an "other self" causes the real counterpart to lose his/her attachments when becoming free of grief, including love. This occurs with the death of Chariot and Arata's potential "other self"; Kagari lost her love for Yomi, and Arata for Takuu.

One particular "other self" of interest is Black★Gold Saw, who appears to have control over reality in the Otherworld itself. She seemed to be able to stop the flow of the destruction in Chariot's world, to the point where it was like stopping time, and the blades that cut the fissure that carries Dead Master away seem to cut into reality itself. She also has the ability to create strange hooded figures from a watering can, which are implied to be incomplete "other selves" that are weaker and have less autonomy; this could potentially mean she has the ability to make "other selves". Her duty, given by Yuu, was to protect the Otherworld.

Mato disapproves of this way of dealing with grief, saying that differences should be resolved directly by talking.
