Chapter One

What happens when a new girl comes too Marco's school? And she looks just like him!!!

"Kids today we have a new student! Now listen up!" Once the teacher said that a girl with long brown hair tied in a ponytail walked in. She was wearing a red dress and black leggings.

"Pst! Marco!" I heard Star whisper "Marcooo!~" I heard her again.
"What!?" I half whisper shouted. "That girl looks just like you!" She said pointing at the girl who walked into the class.

Ps.
I don't own Star Vs The Forces Of Evil obviously. This is just a fanfiction about if Marco had a sister. I tried to find one about him having a sister but I couldn't find a single one! So... I wrote one! I hope you like it!!!!!!!!!
