Actually, Le fay did important things in this volume, and increase her relationship with Issei(Additionally, we have infomation about her, the contract thing was something necessary due to the change of Issei, not only because he wasn't a pervert anymore, but also because he had increased his rank as a Devil). I don't know what do you mean with those questions,  but remember thay Le Fay is a great Magician and brother is considered one of the strongest humans,  so it's logical that they fight. Also, remeber that Incinerate Anthem(Walburga's ex longinus) has already chosen another wielder,  and that is Lint Sellzen; this was stated long time ago in the novels.

Anyway, we have very little information about this volume now, so it's normal to have questions and think that there are things that are "incomplete",  but they will be solved when the translation is ready.
