Wait so this makes the anime look good? Not for the pacing but the characters shown. No cat lady, no shop guy, no subplot for demon king, not even the tea party. So in the LN this all happens but really slowly or at quite the same pace as here?
I stopped reading due to lack of time and lack of motivation (I still bought I think 5 or 6 volumes...).
The WN doesn't have them up to the fantranslated chapters that I read.
The LN parts I read were pretty much the same thing as the WN.
So you seem to have misinterpreted what I said. When I said someone doesn't exist, it's because they really don't exist.
We do have characters that exist in both, like the weapon shopkeeper, who is just a generic old man in both novels, but the characters that don't exist are characters that are exclusive to the manga version, like the ones I mentioned.
I haven't watched the anime myself, so I don't know any of the details. I was surprised when I saw that the giantess Sylphy appeared in the first episode, which indicated being closer to the manga, but it seems that he got Lucelia not long after, which indicates being closer to the novels.
That's all I can say.

Edit: I guess I now noticed another thing. In both versions we have a "plot of the Demon King", however, while in the manga we first learn of the existence of this Demon King during Lucelia's summoning, which has all those events happening as we saw in the manga, in the novel, we hear about it much later, when the Demon Baron appears and explains that the demons are acting in the dungeon under the Demon King's orders.
Lucelia is unrelated to these, although, if I remember correctly, she did seem to be aware of the existence of this Demon King, but
this is more to indicate that these servants we see may be existing entities that somehow "become cards" (the Demon Baron, once defeated, becomes a card and becomes a (level reset) summoned ally),
rather than suggesting that Lucelia is a direct victim of the Demon King for whatever reason (Like we see on the manga)
In the novels, we have no idea what happens to the servant when they are back to the card, there is no "world of the gods" or "demon world" in the first chapters, and there is no communication way, so when MC promises to go to the dungeon at a day, and he is unable to, the servants could not be called, and don't know anything on why they were not called, so they sulk when he summons them past the time of the promise.
But these are details in the manga that I could see being introduced later in the novels, although it does feel like it would contradict itself in some ways.
