The card shop doesn't sell, says the young man. He's going to research the mechanical armor, but he needs to sign the "martial soul contract" , which is a kind of contract between a soul and a person. The contract says that the soul will never betray the person who signed the contract, so the person signing the contract can't break the contract. The young man wants to know where the mechanical armour is, but the old man says it's in a weapon storage. The old man is surprised that the young woman is so interested in mechanics. He thinks that she's just having a good time, and that she must have been with some bad dudes. The man says that they should leave the young lady some food, and go see if the soul armor will work. He says that she is a genius, and the base is hiss now. They'll go back in a couple of days to see if it works, and then they'll come back and see if they can use the soul armour again. The guy says that he hopes there's someone nearby who can help them, because he's a rookie, and he can get excited easily. The enemy is right there, he says, and they need to end the problem by force.
