Basically i recommend if you use the bow (they drop at the entrance of the angel/devil (?) Statue) and just dodge the running attacks (only attack she she tries to throw something at you)
I think i beated her with the sword you get from the fox girl (forgot her name :(. ) Tbh, the best strategy on any boss imo is dodge and then attack as the enemy recovers.
That was my strategy for my speed runs at defeating all of the bosses on the previous update, get the sword first and than challenge the rest of the bosses. I think my best time was around 30 min. Looking forward to more boss fights and sex scenes.
