~Luna's PoV~
I land behind the gate of the castle and walk inside. The castle's insides are similar yet colored much darker than the one I'm used to. Just then a familiar black panther appears. "Hello, Luna. I need you to go to a certain room and find a certain book. You'll know the book when you see it. If a girl with angel wings tries to stop you, let Death take control, just don't let Death kill her, the girl is very much needed." Lucifer said before disappearing.
"What was that about?" Death asked me. I ignored her and started walking towards where the rooms were but then a girl with short brown hair and golden yellow eyes walked up to me.
"Who are you and how did you get in here?!" The girl demanded. "This must be the girl dad was talking about. Let me handle it and if my way doesn't work then you can take control." I told Death in my head.
"My name is Luna and I walked in after flying over the gate." I answered the girl then asked, "What's your name?" I waited as the girl looked me up and down.
"My name is Frisk." She said, unfolding her pair of angel wings. I took a step back as her angelic power was strong. "And you're trespassing on Royal property." Frisk added.
"I'm here to take my sister back home." I said, then Death decided to speak through me at that moment.
"Actually we're here to kill her." Death said before letting me speak again.
"No we are not here to kill her Death. There's gotta be a way for us to help her without killing her." I said, shaking my head.
Frisk then said, "Well I doubt your sister is here. What's her name?"
"Chara." I said, Frisk took a step back, nearly tripping over the rug behind her.
"Chara isn't here, she's in the woods planning something. I would suggest you leave and never come back." Frisk said. "Besides, whoever told you that you were her sister is wrong. Chara has no siblings except Amy. Now go before I have you kicked out of here." She added.
