Ninja

A Ninja (忍者, Ninja^?) is a term referring to a type of covert agent or mercenary that existed in feudal Japan. They are in a state of decline in the modern age, despite some ninja clans still existing in modern times with some now operating globally, and are trying to restore their prestige in the world.

Ninjas were originally bandits that were hired by some powerful military leader. This humble origin allows for anyone to become a ninja. Ever pragmatic, the ninjas uses things from the clothes on their back or even the lack of it to their advantage. Moreover, ninjas always use contemporary weapons for their purposes and disguised them, such as arquebuses camouflaged as staffs and inro, though is apparently not adverse into using traditional weapons like the uchine. They also apparently prefer weapons that don't stand out too much like an uchine, specifically those that can be concealed or disguised. Finally, ninjas apparently prefer to kill on the first strike and if that fails quietly retreat over a protracted battle. Ninjas don't also lay down their lives for a single goal.

The distinct techniques practiced by ninja are often referred to as ninjutsu (忍術, Ninjutsu^?). Unlike the more fantastical depictions often seen in stories, the real tools and techniques tend to be much more mundane and grounded. Stereotypical depictions of ninjas, which in many ways differ from reality, often have them in black robes with a hood and cloth mask concealing their face apart from their eyes. Weapons often associated with ninja include kunai (苦無, Kunai^?), shuriken (手裏剣, Shuriken^?), kusarigama (鎖鎌, Kusarigama^?, lit. "Chain-scythe"), and short swords. Ninjas are often trained to possess considerable athletic abilities.

Alternative terms often used referring to ninja are shinobi (忍び, Shinobi^?) and kunoichi (くノ一, Kunoichi^?) (the latter referring female ninjas).

Recent History

According to Hattori Hanzou, ninjas are supposed to be in supporting roles as they live in the hidden darkness out of protection and not be in the spotlight. However, as time went on, "pure lines" or families began to spring up like the Hattori and Iga. Hanzou argues that by the time ninjas have "pure lines" they cannot survive in the world. It is likely why the ninja are in a state of decline.

Currently, the Kouga and other ninja clans have been operational in the shadows for a long time and have managed to continue doing so even into the 21st century to varying degrees. Recently, due to changing times, the groups have been looking into Academy City's Power Curriculum Program and Gemstones, and, as such, have been seeking to obtain the means to develop genuine supernatural powers. They do not seem to have any awareness of the existence of the Magic side.

Background

This section requires expansion General expansion, partial transfer from Principles

Ninjas came about in feudal Japan, originally being bandits hired by powerful military leaders. Over time, ninja clans such as the Iga and the Kouga emerged, along with "pure lines" or families like the Hattori. Over the centuries, even as their primary period of apparent activity passed, various myths, stories and stereotypes arose concerning ninjas.

While some ninja clans are more or less extinct in the present day (either through gradual decline or extermination), some clans and bloodlines, such as the Iga and Kouga, still exist in the shadows of the modern age, with some operating globally, but they are in a state of decline. As such, a number of them have trying to restore their prestige and place in the world, and to that end they have been looking into the possibility of obtaining advanced technology, capable of producing lost or imagined ninjutsu, or the means to develop genuine supernatural powers.

In mid-October, several Kouga members led by Oumi Shuri, infiltrated Academy City with assistance from Tsurigane Saryou, a Kouga ninja who had previously gone in undercover as a Child Error, and participated in the Second Reformatory's Jailbreak Trial for the purposes of observing Academy City's technology and learning what they could for the Kouga. After the trial, when Tsurigane openly betrayed them and they learned of the apparent circumstances behind her change, Oumi Shuri decided as a senior ninja that Academy City's technology and techniques were something they should never touch again, leaving Tsurigane to be judged as its citizen. Following these events, after escaping from imprisonment, Tsurigane approached Iga ninja Kuruwa for training, hoping to regain Oumi's attention in another way.
