Only Snow Villiers can summon Shiva, who appears as the Twin Sisters of Shiva. They're a Water/Ice elemental Eidolon that can transform into a motorcycle when in Gestalt Mode. The older sister's name is Stiria and she has a dark coloured face. The younger sister's name is Nix and she has a light coloured face.

Summoning Stiria and Nix
When summoned, the two sisters fight automatically alongside Snow. Stiria has a Medic and Ravager type of role, and cannot be directly targetted by enemies. Nix has more of a Commando type of role, attacking and has only one offensive magic.

During this time, the Gestalt Gauge can increase by driving up enemy chain gauges or by Snow defending against enemy attacks as a Sentinel. In Gestalt Mode, attacks are done with various control combinations. Diamond Dust is Shiva's finishing move. It can reach a maximum level of three with a full Gestalt gauge.
