The three of them try to figure out a way to get rid of the indura, but they can't. They've got to kill them all with sunflower seeds, which is the most powerful weapon Ban has. He's also got a spear in his hand, which can do a lot of damage. The three decide that they'll have to take care of the monster themselves, since it's not like they're going to be able to get away with killing it with just a bunch of stuff. They also decide that the only thing they can do is to kill it with the seven "deadly sins" of pride, love, and death.
