>>2499868Ok, this is a something that I've actually given more thought into. In the anime version, I believe that each other self has their own territory. If someone else enters that territory, then they are asking for trouble. BRS has her metal spike land that BGS watches her in at the very beginning, there's Chariot's toybox that she keeps Dead Master in until she is rescued by BRS, there's Dead Master's chain graveyard which also contains her army, there's BGS's pillar garden which also had Arata's other selves, and then there's Strength's cube in which the battle between Insane BRS and Strength took place. If there's any reason that they are chosen, other than looking fantastic, I believe that these areas are the other selves respective territories that they live in, which is why they seem to fit their respective owners. When BRS leaves hers at the beginning of episode 1 and enters Chariot's territory, Chariot almost immediately attacks her. Dead Master briefly assisted Chariot during this battle but I believe that it was because in the real world at that time Yomi was trying to push Mato away from trying to be her friend. Until BRS left her territory, everything was stable, except for Chariot having Dead Master as a prisoner. BRS left to rescue her but for some reason continued to fight every other self. At that moment, or maybe even before when BRS left her home, I think that Insane BRS wanted to kill all of the other selves. I believe that Insane BRS is BRS's personality throughout the entire series, she just stays suppressed until BRS transforms in episode 6, and is finally fully revealed when Mato uses her unstoppable willpower to (split off/create/make?) a body that she can control. It's been a while since I've seen episode 8 again so my facts may have gotten hazy in the end of this post.
[spoiler:lit]My thinking cap is super fried from this but I'm ready for the next question. This is the first time that I've actually gotten to talk about BRS.[/spoiler:lit]
