Koko, Joubutsu Yattemasu

One day after school, Rin, a friendless high school girl who is constantly being harassed by spirits, bumps into Ruka, a handsome spirit with a nearly human presence. Normally, spirits disappear when they bump into Rin, but for some reason, Ruka doesn't disappear. The two find themselves chatting away, and upon realizing they have a strange common interest, Rin suggests to Ruka that they team up to provide advice to spirits... A paranormal comedy featuring a non-communicative high school girl and a handsome ghost! (Source: Kadokawa, translated)
