The swords of glass yama dad tells his daughter to take the necklace he made for her and promise her mother that she will not go back to the forest. Aww, that's kind of like saying, "I'm going to get you all killed, but I'm not going to kill your mom." Aww. That's just a little weird. The sword is stuck in the village's sacred stone, and yama wants to use it to kill Orland. He wants to kill his mom, too, but he doesn't want her to be taken away by Orland's army. So he's going to use the sword to kill them all.
