A spirit that rules thunder, one of the six elements made by the gods. It's always discharging electricity, making it difficult to get close to one. Summoners look for them believing that they can awaken inherent abilities, but struggle to counteract the electricity which constant flows from them. It is not as though they are hostile though, they simply cannot control their own conductivity.
