The 604th-generation aquaroid belongs to "Blue Storm Fleet", the elite troop of "Aqua Force". The 604th-generation aquaroids are produced from the concept of further investigation of sailors who succeeded in the theme "defense" using modern technologies.

"Homeros" is produced based on the data of "Paschal", well-known by the title "Emerald Shield", and adjusted so as to possess power suitable to become a sailor of Blue Storm Fleet. While Paschal was armed with "pyroxene", the crystal imbued with mana, the 604th-generation sailors like Homeros can unleash their power from readily-produced hydro engine crystals.

He possesses actual combat experience equivalent of the 618th-generation aquaroids due to late roll-out because of the delayed studies, his potential is impressive.
