Info - OC character

Yuiharu was waiting for her brother Yuuri at the park (note: we know where Yuuri is) as she is walking around while waiting for her brother she falls into the lake and suddenly is transported to another world along with Yuuri. What will she have to do when she is told she is royalty to the demon tribe?!? All she knows she must protect Yuuri at all times.

Note: This anime doesn't belong to me only the oc character does
