What do you mean missing characters? The lightnovel introduces a lot of the characters earlier or in more detail then the web novel did by this point.
anyway, this is actually really weird. The light novel does this section of the story ALOT differently than the web novel did and it's a lot better for it but the manga is doing something different from either of them. In the light novel, they were suppose to have a big battle now with Eclaire, the old lady, and everyone teaming up to fight it. In the light novel, they're stronger by this point and have more people, so Blutopher hasn't been used since the fight with the pope.
For all those saying what happened in the WN, a lot more happens in the LN but they seem to be skipping the first part.
