What relevance does the Erotic Units thing have in the game, is it mentioned in dialogue or something?
Also, Danny Trejo a 16, really?
I really don't know. It seems that the secret files contain things that aren't necessary for the completion of the game. Anyway, who knows about EU? Maybe they're vital! Maybe the whole game has been set up to see the Ally/Betray rate in relation to someone's EU! Whoa, that would be a shock for poor Tenmyouji!
