Qilin's Horn

The Qilin's Horn (Romaji: Kirin no Tsuno; Kanji: 麒麟の角) is a Kekkei Genkai which takes the appearance of either a single horn or multiple horns. Said horn(s) can be rooted in just about any portion(s) of the possessor's head.

The horn(s) function(s) in a manner that is reminiscent of the antenna of a radio. The horn(s) can convert the possessor's chakra into radio waves as well as convert radio waves into chakra. This singular ability allows the Qilin's Horn to be utilized as the means for accomplishing an innumerable amount of daring feats.

Though the Qilin's Horn may have been consistently mentioned in the tall tales about a supposed foe of the Sage of the Six Paths named Daibadatta (Kanji: 提婆達多), the very first individual to have his or her possession of the Qilin's Horn recorded in a strictly historical context would be Chiyome Ushitora. It's completely unknown if Chiyome's manifestation of the Qilin's Horn was a simply a freak accident of a mutation or an atavism which implies that she is a descendant of the nefarious Daibadatta himself.

Shuten-dōji
Without a shadow of a doubt, Shuten-dōji is the Qilin's Horn most (in)famous application. Shuten-dōji involves utilizing the Qilin's Horn's ability to perform chakra-to-radio waves conversions as a means of functioning in a manner that is nigh-identical to a radar.

Casting Shuten-dōji will allow one to detect anyone and or anything that has any sort of physical presence. A basic Shuten-dōji will inform one of the altitude, direction, range, and speed of that which has been detected. An advance Shuten-dōji will add shape onto that list and thus allow one to imagine silhouettes of that which has been detected. While a master Shuten-dōji will finally throw color into the mix and as a result allow one to imagine full-fledged pictures of that which has been detected.

The sheer degree of detection that Shuten-dōji provides is indefinitely superior to the capabilities of any sensor-type shinobi. Unlike a sensor-type shinobi, Shuten-dōji isn't limited to detecting entities as a whole. Instead, Shuten-dōji can be utilized to detect the indivdiual constituents of an entity as well. An example would be that Shuten-dōji could be used to detect the heart of an individual just as much as it could be used to detect the individual his- or herself. This unparalleled degree of detection allows Shuten-dōji to be utilized as a tool for even the most complex of analysis. And through such an analysis, Shuten-dōji can be utilized to discern the structure of an entity to the point where one will become capable of replicating the entity with little to no trouble. Even if that entity is a jutsu!

Last but not least, Shuten-dōji's range is simply unprecedented. A basic Shuten-dōji can encompass the entirety of a village. An advance Shuten-dōji can encompass the entirety of a region. While a master Shuten-dōji can encompass the entirety of a country. However, it should be noted that it'd be difficult for one to analyze so much information. So Shuten-dōji are better off being minimized to the necessary size than maximized to the largest size one can manage.

In-story; Shuten-dōji was named after Chiyome, Doshun, and Sunahama's Jonin-Sensei in an attempt to deceive people into believing that the three of them were mournful about his supposed desertion from Sunagakure no Sato. Out-of-story, Shuten-dōji shares its name with an oni of much renown.

Ibaraki-dōji
Ibaraki-dōji is the Qilin's Horn second most (in)famous application. It involves utilizing the Qilin's Horn's ability to perform radio waves-to-chakra conversions as a means of refueling one's reserve of chakra. Because a nigh-infinite quantity of radio waves have been generated by either lightning strikes or astronomical objects over the planet's millennia of existence, there is more than enough "fuel" for the aforementioned conversion to replenish one's reserve with chakra. The time it'll take for one to completely refuel one's reserve of chakra is dependent upon the the immensity of one's chakra reservoir and the speed at which one can perform radio waves-to-chakra conversions. Thus it tends to vary from person-to-person.

After one's chakra reservoir has been refilled, one isn't required to cease the radio waves-to-chakra conversions. As a matter of fact, continuing said conversions is a handy means of opening any number of the Eight Gates. Overflowing one's Chakra Pathway System with more chakra than it's designed to carry will force the Chakra Pathway System to open a number of the Eight Gates as compensation. The more chakra that one's Chakra Pathway System is overflowing with, the more of the Eight Gates that will be opened. One should take great care not to overflow one's Chakra Pathway System with enough chakra to cause the Eighth Gate of Death to open. For just as the gate's name implies, one WILL die if one is foolish enough to do so.

Weaknesses
First and foremost, the Qilin's Horn has a natural weakness to the Lightning Release.


 * Lightning Release produces radio waves that'll disrupt the radio waves being emitted by the Qilin's Horn. Meaning that a continuous Lightning Release can jam the Qilin's Horn's sensory capabilities.


 * Lightning Release can also be used to produce enough radio waves to throw the Qilin's Horn into a sensory overload. This will prevent the Qilin's Horn from functioning with any amount of correctness for ten minutes at the very LEAST.


 * Though it should be noted that it'd take S-Rank skill in Lightning Release to cause a sensory overload from a large distance, A-Rank skill in Lightning Release to cause a sensory overload from a short distance, and only B-Rank skill in Lightning Release to cause a sensory overloard through direct contact. Lightning Release of C-Rank skill or lower have little to no chance of causing a sensory overload unless they're spammed en masse.

Second; if the Qilin's Horn is damage, its efficiency will drop in direct proportion to the amount of damage it has sustained. Though a Qilin's Horn can regenerate as long as the roots in the head aren't destroyed, it'll usually take months for that to occur or even years if the damage is great enough.
