Rei Hino, the civilian identity and present-day incarnation of Sailor Mars, is a shrine priestess who lives at Hikawa Shrine with her Grandfather and the crows Phobos and Deimos. She has an old-fashioned way of thinking and is very traditional. Sailor Mars is stoic and pretty deep, which makes her a mysterious character. That's why she behaves like this in our fanart Sailor Moon Sailor Mars Shows Tongue Sticker.
