Sylphyleel

The God of Wind of Etherdia.

He accidentally caused the death of the protagonist, Takumi, due to a blunder while attempting to repair a rift in space-time. Driven by guilt, he reincarnated him into another world and granted him a new body along with several "cheat" skills as compensation. Though generally gentle and approachable—with a somewhat ditzy side—he watches over the adventures of Takumi and the twins from the Divine Realm.

However, he appears to be harboring a grave secret deep within regarding the twins' origins and the Water Goddess.
