These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Les Yay: Antonia toward Eris. In the OP, Manami and Aoi give off this vibe toward each other, even though it isn't in the actual show.
Magnificent Bastard: Jens and Muttley's plan, executed in episode 10 and expanded on in episode 11, contains copious amounts of textbook chessmastery, neutralizing almost every course of action the Catians and their allies could possibly take without leaving their office. Meanwhile, Jens herself is entirely capable of the sort of hands-on approach that separates the Magnificent Bastard from that trope, along with the requisite flexibility ( buying her own magical talismans after seeing how effective they were against her forces) and political nous (subtly manipulating government actions in order to deny the heroes yet further options).
