Fyi, they're called Magical Barrier Particles everywhere, but another way of phrasing it is "Anti-Magic Particles". Kodansha USA calls it "Anti-Magic Devil Particles", probably because "Ma" is another way to say evil/bad, and in the context, the evil/bad is a demon. The kanji for sho is like a disability, or the act of disabling, so that's where the anti-magic comes from. Ryushi just means particles. Or so I am gathering for all of the above. Basically, the chapter only makes "sense" if you adhere to the "barrier particles" name. If you actually look at what it means, which is Anti-Magic Particles (reflecting what it does), then it gets worse, imo.
