Well Rachysty seems like a sort of russified version of Racist (french) or maybe some mix of Rusky or something, and it's "From Paris with love" if I can decipher it correctly.
A variation of Rascist (not racist), a new word combining Russian and fascist, its use is widespread in English-language content from Ukraine. The spelling "rachyst" is a French homophone of the English pronunciation, the trailing "y" is the plural form as in the Italian "fascisti", where the word originated. Spelling it with "y" is probably just an artistic touch, or to make it look more foreign.
