Vanir comes in as a potentially scary Non-Elemental attacker. He has a 5x Non-Elemental attack that can inflict Blindness and gets stronger every time you use his Skill. But that's not all...he's also an Anti-Shield card similar to Siegfried and Fam Taos, inflicting Damage UP to foes if they have an active Shield, making Vanir notably effective against enemies who use Unbreakable Shields. While his uses may be limited against Event Bosses, it makes him a complete terror for Colosseum and Duel Match (though the latter is unlikely due to his high Cost).
Vanir was one of the Devil King's generals who ends up taking over the management of Wiz's magic shop. He is the devil of foresight and one of the dukes of hell, with the ability to read everything about anybody, but he cannot read anything about people that are as powerful as he is (the Devil King's generals and other dukes), people stronger than him (Aqua and other gods), and people who are a little weaker than him; these people have their readings clouded and incomplete. An exception to this is Kazuma, whose cunning nature makes him hard to read. He also has very powerful combat skills that he refuses to use on humans.
