Helga: Veronika's Minion

As Klarissa is Hitomi from the perspective of Sayaka Helga is Sayaka from Hitomi's perspective. Like Veronika, Helga is based on a creature from Greek mythology. Sayaka is depicted as an enraged simplistic cyclops, with a sword in place of a club. There are music symbols all over the body, representing her true nature to an extent. As a deceiver Helga will guide the humans to Viktoria only to literally stab them in the back.
