I feel like a lot of people seem to forget or don't even realize what is actually being adapted in situations like this. If you read the web novel at all or such, well good for you I guess, but if there's also a light novel version it probably changed a bunch of things and that'd be what's used as source material for manga or anime, which can also change all kinds of things as needed to suit the different mediums. It's like you're working off of knowledge from the rough draft, but there's an editor or two now and there have been revisions.it's not in the web novel. it is in the light novel though (volume 4, chapter 1 which is around when sudou meets lupis in the civil war act)
