Kyon-kun from The Melancholy of Haruhi Suzumiya wears a white shirt then again so does every guy it's part of the school uniform and even the girls uniform has some white in it but it's mixed with blue and red for the symbol.
I was thinking of Haruto in particular, but all the exorcists in Haunted Junction wear some white. Haruto is the son of a Christian minister, Kazumi is the son of a Buddhist priest, and Mutsuki is the daughter of a Shinto shrine maiden.
