Chapter 6: Answers
It wasn't long after Yusei arrived that Luna and Sayaka came in. Akiza was there who was apparently watching Leo with Jack and Crow.
"Who's the girl?" Jack asked.
"The name's Sayaka," she answered with a slightly irritated tone. "Be happy that you're not a witch or I would so kick your butt."
"A what?" Crow asked.
"Good question," Leo asked. "And another is, where do you keep going, Luna?"
"Uh, killing witches," Luna answered.
"What's this about witches?" Akiza asked.
"You sure we should tell them?" Luna asked her friend.
"Is there an option now?" Sayaka replied.
"True," Luna agreed.
"Someone better start explaining this," Jack demanded.
"Luna and I are known as Magical Girls," Sayaka started.
"Magical Girls?" Crow repeated.
Luna nodded. She held out the hand with the ring on it. The ring glowed and vanished as her Soul Gem hovered until Luna grabbed it.
"What is that?" Akiza asked.
"It's called a Soul Gem," Luna answered. "I first received it last night when I became a Magical Girl."
"What's a Magical Girl again?" Leo asked.
"You remember Madoka, right Leo?" Sayaka asked.
"The pink haired girl who killed that monster? And the one that disappeared?" Leo replied.
"That's her. She was a Magical Girl and that monster is called a witch," Luna explained. "And she didn't disappear."
"What happened to her?" Jack asked.
"Last night, Madoka and I went together on a witch hunt so I could see the responsibilities a Magical Girl does," Luna began. "But when she defeated the first form of the witch, a larger and more powerful form came from inside of it. And it… ate her."
"It what?!" Akiza responded.
"It swallowed her and spit out her Soul Gem only for it to shatter. I was there when it happened too," Luna explained.
"And I was there," Kyubey said climbing onto Luna's shoulder.
"Did that thing just speak?" Crow asked.
"Yep, Luna is a very powerful Magical Girl," Kyubey said. "With Kyoko, Sayaka, and Homura's help, they'll kill the Walpurgisnacht witch easily."
"The what?" Jack asked.
"The Walpurgisnacht. It is the wickedest of witches. It will destroy the world if the girls don't destroy it," Kyubey explained.
"Wait, so why is Luna a Magical Girl?" Akiza asked.
"She found me being attacked by Homura and protected me. I had always known that she had incredible Magical Girl potential. In fact, that was the reason I came here in the first place. As I did with the other Magical Girls, I had offered her the chance to become Magical Girl. In exchange for becoming a Magical Girl, I get to grant any wish in the world. Someone could even change the universe if they wanted to," Kyubey explained. "When Madoka was fighting that witch, I was by Luna. Then Madoka was killed and the witch started to go after Luna. In order to defend herself, she made a wish and became a Magical Girl."
"And she's going to be putting her life on the line how much?" Leo asked concerned.
"You typically have a witch attack once or twice every night," Sayaka answered. "I'm a veteran Magical Girl and was a friend of Madoka. And the witches themselves isn't the only way to die."
"How else can you die other than a witch killing you?" Leo asked.
"Weren't you there when Madoka was explaining this?" Luna asked.
"I forget!" Leo retorted.
"For one, the Soul Gem of the Magical Girl is literally their soul in physical form," Sayaka began. "So you don't want to separate yourself more than 100 meters."
"Why not?" Crow asked.
"We're pretty much lifeless husks without our Soul Gems. If we lose range of the Soul Gem, we die," Sayaka said. "Almost happened to me."
"Wait, what do you mean you're a lifeless husk without your Soul Gem?" Akiza asked.
"The Soul Gems are us. When you become a Magical Girl, you are still alive in a way, but the only life force you have is the Soul Gem. If it is destroyed, your life force is gone along with your body. We're pretty much dead but we're alive at the same time," Luna explained.
"How can you be so calm about that?" Akiza asked shocked.
"It's a fact of our life once we become a Magical Girl. And once you become a Magical Girl, your first duty is to kill witches so they don't harm other people," Sayaka explained. "When our friend Mami first took me and Madoka on a witch hunt, a woman was cursed with a witch's mark. She was traveling to the top of a building and tried to jump off it. Mami luckily saved her though. She then went into a witch's realm and killed a witch. But the same witch that killed Madoka was the one killed Mami. Homura killed it when it killed Mami but it seems the old witches are coming back. And considering the fact that it killed Madoka, who was the most powerful Magical Girl before Luna, was killed by it, it means those witches are stronger than before."
"And it's up to us to kill it and the Walpurgisnacht," came Kyoko's voice. Last time she was eating an apple and now she was eating a pack of Pocky sticks.
"Who are you?" Crow asked.
"The name's Kyoko. Friend of Madoka's Sayaka's, and Luna's," Kyoko said. "I'm also a veteran Magical Girl myself. Been one longer that Sayaka. And you better be telling them everything, Kyubey. Last time you talked like this, you kept a ton a secret and it almost cost Sayaka her life."
"What does that mean?" Leo asked.
"He didn't explain to us that we were dead originally or the Soul Gem proximity rule," Sayaka answered. "Because of that, Madoka tried to stop a fight between me and Kyoko. And that ended up throwing my Soul Gem off a bridge and onto a truck. If it wasn't for Homura getting my Soul Gem back to me, I would've died."
"What are you anyways?" Jack asked looking at Kyubey.
"I'm what they call, an Incubator," Kyubey told them.
"Incubator?" Yusei asked not having heard this before.
"Yep. My kind go to people who have Magical Girl potential and grant their wish if they want it. Mami was dying when I found her after a car crash. I forget exactly what she wished for, but it allowed her to live," Kyubey explained. "That is, until the witch killed her."
"How can you say that without any sadness or sympathy?" Crow asked. "The girl died!"
"Incubators don't have the ability to feel. So when we found Earth, we were quite intrigued by the energy emotions gave," Kyubey answered.
"By the way, have you said what happens when your Soul Gem turns completely black and what the black in it means?" Kyoko asked.
"No, they haven't," Jack asked. "So spill."
"When you fight a witch or you start to go into despair, your Soul Gem will slowly turn black. You can cleanse the Soul Gem by using Grief Seeds left by witches after you kill them," Sayaka began.
"And what happens if you don't cleanse it? What happens if it turns completely black?" Crow asked.
"Magical Girls work to spread hope while witches spread despair. And when a Soul Gem is tainted into despair and darkness," Kyoko looked at Luna to wrap it up.
"The Magical Girl will become a witch herself," Luna finished.
"So you can become a witch?!" Akiza asked shocked.
Their Soul Gems began to pulse. "Well, what do you know?" Kyoko said. "We need to go."
"Where?" Jack asked.
"Kill a witch. Now stay here where it's safe. I'm not letting you get sucked into a Witch's Realm," Luna ordered with a determination that shocked everyone.
"Since when are you so strong and determined?" Jack asked.
"Since I became a Magical Girl and received a duty that needs me to be strong and unyielding," Luna retorted.
"Come on, guys! Homura's going to beat us to it!" Kyoko called.
With that, the three girls ran out.
"How on Earth did she become a Signer and have to have another life or death duty?!" Crow exclaimed.
"Not sure. I just hope she'll be alright," Akiza said.
"Wait, where'd Leo go?" Jack asked noticing the missing boy.
"He didn't…" Crow muttered.
"Please tell me, he didn't follow those girls," Akiza said.
"If he did, then he's going to get into a world of trouble," Yusei said. "We have to go after him."
"I'm not risking him getting killed. We know Luna can take care of herself, no more than ever. But her weak spot is with Leo. If he gets involved, she might just end up dying because of the distraction of protecting him," Jack said. "Akiza, stay here while we go get Leo."
"Right," Akiza agreed.
And then the guys darted off to find Leo.
