A heavily armored soldier who appears in the tales about the migration of a group of refugees towards El Gaia. Having rescued Reed and his party from danger an innumerable amount of times， everyone acknowledged his ability， though his past and identity remained a total mystery since he never took off his helmet in front of others.

However， no conclusive evidence of this has been found.
