|Holy Water Sword|
A Holy Water Sword is a kind of Magic Weapon, assigned to Warrior Angels who have an elemental affinity to Water Magic and are specialized in using a sword. The sword performs the normal function of a blade, being used to cut or stab people, but is also a magical focus. It is possible for the wielder to cast spells through the blade which seems to boost the power and enable new effects.
The blade might be protected by a Holy Protection Enchantment like the Angel Emblems. It was later revealed by Chu that only the blades on Angelic Weapons will burn Demons/Rhea if they touch them. Buwaro can be seen holding Kieri's Sword on page 206 and Tsavo holding Kazai's Weapon on page 640.  
- The writing on the sword is Angelic but it doesn't mean anything. Chu didn't create an Angelic alphabet, grammar or vocabulary so it's just decorative.
- The length of the hilt is inconsistent. In early comics, the sword is single–handed but in later comics the hilt is lengthened for two–handed wielding.
- The Angelic text on the blade also changes length. Early comics have it taking up two thirds of the blade, later comics are one third.
