Eyes of Lucifer

The Eyes of Lucifer or "Copying Eyes" are a special set of eyes that grant the wielder a number of abilities. They can only be inherited by members of the original Satan Clan and are said to be the strongest ability in history. There are three known forms-

First Form: Stage 1 Eyes of Lucifer
The first form known as Stage 1 Eyes of Lucifer manifest as a pair of eyes with three tomoes around the pupil. They come in a variety of colors with Ichiro's being Dark Pink.

In this stage the user is granted incredible clarity of perception, enabling them to read lips or mimic something like pencil movements. In combat, this allows them to see fast-moving objects and, once fully developed, offers some amount of predictive capabilities: they can anticipate an opponent's next move based on the slightest muscle tension in their body and act accordingly to dodge or intercept. Although the user can see these things, they also need the physical ability to actually act on the visual information. The only wielders are Ichiro Lucifer, Vali Lucifer, and Vali Lucifer father.

Second Form: Mangekyo Eyes
A Mangekyō Lucifer eye is distinguished from a normal Lucifer eye by its appearance, which changes the form of the tomoe seal. The exact design differs for each user, although all resemble pinwheels.

This form is only awaken by a intense traumatic death of someone close to the wielder. In this stage the user gains the ability to copy other Devil's Clan abilities but only through watching them do it although they still need the skill and physical abilities in order to use it. The other two abilities are the ability to hypnotize a person and the ability to grant a person illusions by showing them the eyes. The only known devils in this stage are Rizevim Lucifer and Ichiro's father who Rizevim said was a prodigy.

Nine Tails Lucifer Eyes
The Nine Tail Lucifer Eyes (or NTLE for short) are the strongest and most powerful of the three Lucifer eyes. How to awaken them are unknown due to the only one who has awaken them is the Original Satan Lucifer. These eyes take the appearance of the regular Lucifer eyes except it has nine tomoes and three rings around the pupil. Along with the three other abilities the wielder gains three more-

(1.) The ability to control both Yin and Yang (physical and magical) energy in the world. This could be used to multiply their physical or magic strength at the cost of one or the other. They said this technique works on a basis of multiply one X10 while causing the other to divide by the same amount.

(2.) The ability to absorb energy from other beings to gain their powers. By using this ability the wielder can gain the ability to use light spears, light weapons, etc. or gain special clan abilities like the Phenex clan ability to regenerate but they will only be able to hold it for a short period of time.

(3.) The third and final ability although it is only by myth is the ability to turn a human or any creature into a devil through a bite. Although Lilith is known as one of the mother of all devils there is suspicion that she was originally a human and the Original Satan Lucifer used this ability to turn her into a devil.
