After eating and drinking to her heart's content and taking a bath, it was already midnight.
Roy lay on the bed, flipping through a torn half of the Black Magic Book. The preface and theoretical summary had been torn out, leaving only a few insignificant words barely covering the unlocked Magic Runes.

Roy held a sigh at the tip of her tongue, "If only I could learn them sooner."
