Japanese Speaking Style: "-da ze" ???

[Murakumo]

I sometimes encounter certain casual-speaking anime/manga characters add "-da ze" (da-ze) at the end of their sentences . I also prominently see Touhou's Marisa add "da-ze" at the end of her sentences.
What does this "-da ze" indicate specifically and when is it used plus by who?

"Da" is the informal form of "desu" (the copula). "Ze" adds enphasy to the sentence and doesn't really mean anything by itself. The whole "da ze" is not formal at all, as I said it makes the sentence stronger and it's rather informal, you'll probably only hear it in anime.
A lot of things we hear in anime are too informal to be used in real life, or also impolite like the verb "to eat": in anime they say "kuu" a lot, but it's impolite and you shouldn't say it, but use "taberu" instead.

Well, "da" has already the collegue about me good descriped, But I'll at least the usage of "ze" tell.


Basically is "ze" in our alphabet-character converted this "!" - it led the set an stronger expression. But "ze" isn't the once/only that this function has: Often do you hear/read surely at animes, mangas and etc. the end particle "yo" (Yo - is the basic level of !) after this coming "zo" "ze" and "na" (Well, "na" has the same function how his "friends", but if you "na" use then has the set nevertheless an order-attitude, but at "na" is then a wish/order not 100% surely/safe - what maybe an impossible whis/order is, did you understood?).
