I was totally right when Siren had the headphones on & that Mephisto had the same ones. Only took them how many episodes? The fact that Ako is Muse now helps me understand how Ako “found” the healing chest from the earlier episode. But Otokichi having some relationship to musical Major Land is still iffy makes me think they just penciled that in to make it flow better.
Noise = Dune [Any relationship?] I’m sorry but really the main baddies all have to have 4-5 letter names?? Couldn’t they pick better names?
