I know next to nothing about openings, and I'll try to notate:
e6, d5, Nc6 [not Kc6], Bd7, Qe7
lichess.org/editor/r3kbnr/pppbqppp/2n1p3/3p4/8/8/8/8_b_kq_-_0_1How does the opening naming of the analysis board work regarding: Nizmo must be white's opening. Shouldn't black's opening show up?
White's opening takes precedence in the nomenclature. It's why the Slav defense is a line in the Queen's Gambit, and not the other way around.
It isn't an opening. It might loosely be called a "system," and it's similar to something I've seen in a few blitz and bullet games, where Black plays some combination of b6, Bb7, Nc6, e6, Qe7 and 0-0-0, preparing to attack on the Kingside, assuming White has castled there.
If you're looking for more information on this and related "openings", you're likely out of luck. I doubt anything has ever been written about these. If anything, these types of set-ups are Exhibit A on why most amateurs shouldn't study openings beyond the basic principles and a few set plans. It's probably not a good opening, and it might not even be sound, but it won't be the reason anyone under 1500 loses the game. And it can also be fun to play these sorts of things on occasion, though I'm not sure how much you can improve longterm if you always play like such systems.
@Letgoofmychessego I believe that's the famous "Wtf did I do" opening, which is rumoured to derive its classical name from a standard muttering of Black from about move 12 onward, when they realise that they left their king almost bereft of support against a murderous White onslaught.

How so?
First, castling long is often more of a challenge to defend than castling short. You have three pawns to defend on the abc files, but the K finds itself on the c file. So you will probably have to use up one additional tempo moving the king over further. That moves it farther from the rook, which is not defending any of those pawns, unlike when you castle short and the rook is beside the king defending the crucial f pawn. Now your Q is blocking the B on f8. So probably you'll end up fiachettoing the B on g7. That means more extra tempos lost, as you first move g6. Then that B is on the far side of the K so not defending it. Alternatively you might move your Q again to develop the B but that again costs an extra tempo. And you are black to begin with, which naturally lags white, and have just given away at least two more tempos, and the fianchettoed B not defending the K.
A third vulnerability arises because the N on c6 is blocking the pawn on c7. So in the event of the inevitable pawn storm from white on the queenside, you can't head off an attack by confronting a b pawn in mid board with the c pawn, backed by a piece or two. Rather, you almost have to sit and watch it happen as white's b pawn attacks your only defending piece, or worse, use the a-pawn and create a vulnerability in front of the king. Meanwhile the light bishop is blocked by the N, and the N cannot retreat to the back rank if the K and R are where we left them (without costing yet another extra tempo). So it will be awkward to free the c pawn or activate the light bishop, which is the only one with a chance to participate in defense. So to sum up, you will lag white's development, have difficulty activating your Bs, have a blocked pawn on the c file, no R protecting a pawn near the K, and a N with restricted mobility. Of course, there is a game to be played. You'll aim for a strong centre and an attack of your own. But it seems that white will have strong attacking advantages and an easier time defending its own king.
