This Troper just realized that the Octo-Squad actually has a fairly Meaningful Name, at least as of 2nd Original Generation. All of its member use Duel Weilding / Guns Akimbo in some way: Katina's Duel Plasma Stakes, Russel's Duel Plasma Cannons, Leona's Blade Railguns and Tasuku's Seize Anchors. Four members, each with two weapons. In other words, 'Eight Arms'.
In Moon Dwellers, Jua-Mu receiving the Coustwell Brachium after becoming more unhinged make a lot more sense when you realize that Coustwell Brachium has a lot more potentials of literal No-Holds-Barred Beatdown attacks, something that would fit the insane and crazy Jua-Mu more.
May also have to do with Ouka's views of Latooni distorted due to the suggestion and brainwashing as a side effect, Ouka does care for her fellow friends who survived the School before. Latooni, Arado, and Seolla were all she had to consider as a family aside from a large supercomputer.
At the ending of the "The Inspector" Anime when Beowulf appears, everyone shrug off his presence there as nonsense and get back into the fighitng. The thing is, when you think about what he was shown doing in the first episode, plus the strange einst units he bring along (who all look like some mechs of the good guys...) paint a very bleak image of what Kyosuke's corrupted alterego was up to between his two appearances.
