Monochrome Null

Diamond Shine (鑽石服務[ダイヤモンドシャイン]/ˈdī(ə)mənd/SHīn) also known as "Mark of the Rainbow Dragon" is the sacred gear of Ichiro ______, the mutation knight of _____. A support/nullifying type sacred gear that has the ability to change the color of objects thereby changing the properties or abilities associated with the color and replacing it with properties associated with the new colors.

Summary
First used in Life 1 when Ichiro is found by a pack of fallen angels, while trying to escape from death. It is shown to be a very powerful and dangerous sacred gear, by being able to temporary change the properties of objects and things. According to Azazel himself, the sacred gear was last seen during ______________ and after that incident the rare sacred gear went missing for some time.

There is a dragon trapped in the sacred gear known as Zirnitra the magician ancient dragon from Slavic Lore.

Appearance
The sacred gear in it's initial form ___________________ and in it's balance breaker form the sacred gear manifests as a sword except the blade is a paint brush.

Abilities
Diamond Shine primary power is the ability to change the colors of objects which nullifies the properties associated with that particular color. For example, if Ichiro were to paint a piece of iron (normally gray) orange and black this would cause the iron to rust in seconds. If Ichiro were to paint his own blood black, it would cause it to turn into ink thereby making it impossible for him to bleed out (since he no longer has blood but ink running through his veins).

But this goes beyond just ordinary items for example, if Ichiro were to pain Rias's crimson red hair white, this would prevent her from using her Power of Destruction due to her Gremory heritage being erased. Or if Ichiro were to paint Issei's boosted gear from red to any other color, it would temporarily become a ordinary twice critical due to no longer having the association as the gauntlet of the Red Dragon Emperor.

It's balance breaker known as Lexicus Buster takes the shape of a sword except the blade part is a calligraphy brush. It has two separate abilities: The ability to erase radicals/kanji/names and the ability to create Kanji/radicals using existent ones. For example: The erasing ability: He can erase the sense of a person has about themselves. I.E.: He can 'Erase' Sona's surname, and thus she's unable to use the Sitri's water abilities(It won't work on Rias because her power ties with her Bael heritage); he can 'Erase' several radicals from issei's name(一誠), until it becomes just the radical for 'Corpse" or 'asleep'(尸), meaning instant victory. The creating ability: he can both create or manipulate kanji in order to defeat or incapaciate his opponents. He can modify the "Ashi" of Asia's name((アーシア; which is pronounced 'Ashia") and turn it into "leg"(脚; ashi), therefore he can use now his 'erase' ability to attack her, erasing such kanji and then cutting her legs off as a side effect. Another example is turning Yuuto's surname 'Kiba'(木場; which means 'tree location') in either Fang(牙; Kiba) or then turn the last kanji 場(Ba) into 刃(Ba; but means 'sword') and then erasing it so he loses all of his abilities to wield a sword. As a bonus, the brush sword makes zero damage, it just 'marks' the victim with either black(writing) or white(erase) ink tints, making the opponent think it's a harmless ability without noticing that the last strike might be deadly. If he hits someone's wings(翼; tsubasa), he can either make them heavy or make their feathers flock away, since he'll cut the kanji for it apart to Feather(羽), Rice field(田) and Link(共); he can turn a line of chairs(椅) into a forest of trees for protection since it'll cut other's kanjis into 木(tree), large(大); he can turn a wood(木) floor into water(水) since the two look alike, and so on.

Weaknesses
The color ability: Since it has the ability to change colors, a either blind people or people with their eyes closed won't be effected, even if the color does change. If Issei or vali close their eyes during the first power, even if their armors do change colors, they'll still think they're the red/white dragon emperor, and be able to boost/divide. If they open their eyes and see the change of colors, however, they'll be affected. The blood ink won't work either if ichirou is unable to paint the blood he's losing, as in, the wound is too big for him to paint in time because of the blood lost

The Balance Breaker: There are more than a thousand kanjis, even more than ten thousand ideograms in pinyi'n. But a normal high school student has at least the knowledge of about 150~200,which are used for everyday words. With this handicap, a person would have to remember thousands of kanjis in order to take advantage of this to the fullest. This ability is also useless to names that are western in nature due to it being impossible to translate into Kanjis.
