Lenneth is generally a kind person, but is merciless against her enemies. She is stoic but determined when it comes to tending her duties as a Valkyrie, and then as Lord of Creation. Unlike many of the Aesir, Lenneth does not hold humans in contempt. Rather, she enjoys their company, and eventually becomes their protector. However, those who show little kindness or compassion to others are disliked heavily by Lenneth, who acts very indifferent towards them. She despises those who would disturb the souls of the dead, or those who manipulate humans in general. Lenneth also holds a deep hatred for the undead, particularly Vampires, which she considers abominations. Towards the end of Valkyrie Profile, Lenneth abandons her allegiance to Odin and the other gods as she vows to prevent Loki from destroying Midgard.
