*chuckles* There's no need to be afraid! The tattoo is the 'chastity belt' to keep him celibate. You see, an evil woman wanted him for a mate but he was married to a human and had a cute little daughter. So in order to get this obstacle out of the way, she had an army of Ogres destroy his home, raped and killed his wife AND his child and left him nothing. When he was about to go and kill himself, she conveniently provided a shoulder to cry on. Later on she gets her just desserts! X3
... A ... tattoo .. chastity belt? @_@ I'm afraid.
