Older Sibling Chara

This just started as a thought and a headcannon that Chara was related to Frisk in some way.

So, instead of searching the whole internet for the same headcannon, i made my own story.

Undertale and it's characters do not belong to me. They were created by Toby Fox. I'll probably make my own artwork, but the ones that are not should be credited to the artists.
