This fight is awful. Both bosses deal blows that leave me unable to attack for a while after i get hit and i have to open up my inventory and manually select painkillers, wet wipes, mana restoration and health regeneration constantly during the course of this battle. Not to mention I have to play as two characters that are worse than MC since they can only hit what's right in front of them as opposed to You, who can hit tiles in front of her and can block attacks.
I wish I could skip this fight, the bosses teleport around the map and sometimes directly where I am standing such that I get 腹パン'd or raped. It's buggy and disrupts any feeling of flow you might have when you have to quickly open your inventory to select the item you need.
