As the leader of the ARCHE-YMIRUS Revival Project, Captain Ørn Lodbrok, 7th successor of the Lodbrok Family, has extraordinarily rare mental strength. He’s able to freely control “FROST LIGHT” from afar to battle according to his consciousness. In order to enhance the link with “FROST LIGHT”, scientists from the Kingdom of Veck especially designed a psychic enhancement helmet that greatly strengthens the psyche to achieve nearly 100% synchronicity with FROST LIGHT and increase their operability. However, psychic enhancements are a heavy burden for the brain so even members of the talented Lodbrok Family can only maintain the enhancement for 10 minutes; as such, it is only used during the most critical moments.
