26 days later...

(2 A.M)

(Frisk's P.O.V.)

I couldn't sleep so far,today is my 18th birthday! I couldn't wait for when Sans wakes up. Then I felt my arm hurting. I whimpered in pain,trying not to wake up Sans. I looked down at my right arm and the vine was tightening on my arm with the number 0 engraved on it. It's too late...I couldn't stop Chara before my birthday... I heard eerie laughing then the vine started to extend and took me away. "Sans!"I cried as it took me away,but he didn't wake up...

(10 A.M.)

(Sans's P.O.V.)
I woke up and looked to my left"Mornin Frisk,Happy Birthday."I said. Then I realized,she wasn't there. Strange...she always waits for me to make up... I stood up and looked around the room. "Frisk?"I called. Then I heard a scream. It sounded like..."TORIEL!"I shouted. I ran to the source of the scream and saw Toriel looking at her arm whimpering. "Tori? Are you OK?"I asked. Toriel pointed to her arm and on it was a message cut into her arm. "I'm coming for you...all of you..." The message made her arm bleed badly and she told me to get some bandages. I did so and wrapped up her arm. Then I heard a cry for help in my head,"Someone please help me!" It sounded like Frisk! "Tori," I paused until I got Toriel's attention,"Frisk is in trouble! I can hear her!" "W-what?"Toriel replied.

"I...I know it sounds crazy,but I can hear her calls for help in my head."

Then I heard another call,"Please! Someone save me from her! I'm still in the ruins! By Flowey!" My eye glew blue and I called everyone on my phone.

Everyone that was left gathered up at Toriel's house and were very concerned. "I want a sword,but all I have are my claws,and an empty gun."Catty blurted. "Don't forget to sharpen them for this battle!"Bratty replied. There was a lot of chatter after I announced that Chara had kidnapped Frisk. It felt like yesterday when she woke up from her coma,but now it's her 18th birthday and Chara is going to try and wipe out the Underground. Well,no one is going to let that happen.

Everyone got themselves ready and ran outside screaming then they suddenly stopped and we all looked up. The ruins was crimson red and a huge dark vortex was above us. We heard maniacal laughter and out came Chara and Flowey.
