Eva and Sparda

As long as it is not the Neconomicon,then they'll be fine. Not even Sparda would be wise to mess around with such a cursed book. Battling demons requires more than just enchanted weapons. Sometimes magic is what required to slay them even encountering ones that are immune to any sort of physical attack. Sparda is slightly shocked that Eva is very quick on learning magic but once he was told of her family background then he completely understood.
