It's the mysterious woman, and she's using a storage belt to hold all of the potions in her laboratory. The potions in the laboratory are all locked away, but the woman has access to all of them. She's also got the recovery agent, which is suspicious. The potion is super corrosive, and the woman won't be able to find it if she takes it away. The man is back, and he tells the woman to hurry up and fight tomorrow. He tells her that tomorrow is her last day of life, and if she has any tricks up her sleeve, he'll show them off. Before the duel, the man will talk about rules. Both parties can use the props they've already exchanged, but one party can die or surrender. The duel is over if one party dies, surrenders, or dies in the duel. The guy who controls the object will be the one to die.
