Tutti is a doll created by evil, counter revolutionary forces to look like a human girl in every way but isn't. It's from Soviet propaganda in the twenties or something. Story had a happy ending where the counter revolutionary oligarchs are defeated. There's this whole thing about Tutti having her heart replaced with an unfeeling one but it never happening.
Not sure the accuracy of the translation but I'd guess that the implication is that Gunther is a manufactured personality or person without a heart or feelings. Kind of an anti-Russian automaton.
Just my two cents.
