Haruhi Suzumiya from Suzumiya Haruhi no yūutsu/The Melancholy of Haruhi Suzumiya. She first appeared in the Suzumiya Haruhi novels by Nagaru Tanigawa (illustrated by Noizi Ito), then adapted into a manga series with art by Gaku Tsugano. She is an eccentric high school girl but also solitary. She is only interested in paranormal, ufology, supernatural and time travelers.
So here is my rendering based on the anime version, but drawn my way. Hope you like it.
