Isis began to punch Hades like there was no tomorrow, while she wasn't exactly a master at close-range combat. She had fought many monsters, so she knew what to do and what not to do. With her right hand, Isis punched and stole Hades' mana, and with the left hand, she emitted the pollen that covered the sword and made him unable to react. Interestingly enough, the more Isis punched Hades, the more she felt refreshed. At the same time, the desert around was slowly changing its shape due to the impact of her fully-powered punches.
It took a while, but Hades' spiritual body began to shrink since he was losing his mana and receiving damage. However, after a couple of hours, when she had the chance to finish him since he had become as small as a sphere that could fit in her hands, Isis stopped attacking.
