Valentino has been described as being charming and roughly as level-headed as his fellow Overlord, Vox. He does, eventually, show off his real behavior after some time. Valentino uses his charming persona in order to lure other demons into working for him where Valentino admitted spending much of his time in nightclubs, picking up demons and offering them "jobs" at his studios, with him hiding his more violent and psychotic behavior in order to convince them to willingly "work" for him.
