Interesting enough, each of them appears to have some subtle ability, only 2 are revealed thus far, so who says these scenes can't be part canon, so long as they are group? A "If this happened, this would be the result" thing, of situations that aren't exactly on par for the tone of the VN. It would be limited to only what would be possible for them to do, but can go as far as things that aren't so lighthearted/innocent, but certainly nothing dark. It would be about exploring the boundaries of the dynamics of the group and their personalities.
