Called as "descendant of moon goddess", "best protector of humanity", "the chosen against all evils" and "Grimm-hunting nobles" etc., they are the collective for description of groups of people who have heritable trait of moon-silver color eyes which possess special abilities of disrupting and even vaporizing the Creatures of Grimm (and matters of former's similar properties) through the usage of unleashing radial flame-like flash of light come from their eyes.

However, contrast to the popular belief, their silver-eyes power ability is just one, but four variations of silver-eyes power abilities, and the user only inherit one of the four trait variations. These following abilities are included:

• [Silver-eyes ray] : Despite being the most well-known ability and the most longest range one among silver-eyes abilities, this ability is considered as less useful compared to others as it's often rather easy and obvious to identity the vulnerable spots

• [Silver aura]

• [Silver kinetics]

• [Silver blood]

( FUN FACTS: rumors said that the actual Silver-eyes power source is not come from the eyes itself, but rather come from a pairs of eyeball-size flaming orbs placing inside the eye socket.)

In terms of their own equipment, despite having their own interpretation in their own cultural circle, there are two most valuable materials viewed by silver-eyes user for anti-Grimm (and Grimm-folk) weapon making respectively: "Brighting-sliver" and "Moon-shiring herbs".

• "Brighting-sliver", which is prominently used by people of eastern-Sanus silver-eyes groups like [Mountain Samurai] and [forest wandering archer], is the metal which able to disintegrate Grimm-like matter produced from Grimm-folk, cause the Grimm-folk to have burning-like pain effect when touching it bare-hands in their Grimm-form, and eventually negate Grimm-folk's rapid healing ability for being able to permanently kill Grimm-folk foes they encounter, especially those beheaded ones.

( FUN FACTS: There also have the less qualitied one called "Rough-silver", commonly used by lower rank members of said group, despite having similar properties of former mentioned one, not only have less than half effectiveness compare to the former in terms of negating Grimm-folk's rapid healing ability, but also cause several additional amount of pain to their Grimm-folk opponents which reach at certain point even some of silver-eyes users called it "unethical and very brutal".)

• "Moon-shiring herbs", which is prominently used by people of western-Sanus silver-eyes groups like [Rainforest Amazoness], are the collective terms of a series of special herbs which produce silver color fluid for usage of painting on their weapon such as sharped-tip club and arrows like as using hunting-usage poison. When contacting said fluid with surface-skin of Grimm-folk in their Grimm-form, not only cause the Grimm-folk to have burning-like pain effect, but also able to negate Grimm-folk's rapid healing ability in case of weapon painted with said fluid Inserted into the body-tissues, and then eventually able to permanently kill Grimm-folk foes they encounter, especially hitting in vital areas such as heart and head.
