Kamakura

About
Kamakura is one of the three Kurupis brothers, the three progenitor members of the Kurupistonian race who were responsible for a large number of planet Kurupiston's greatest societal advancements.

During the early years of the three Kurupis brothers, Kamakura largely did very little to assist in constructing a society, instead leaving the majority of work to his brother Rose while he played around with their other brother Santos. He was not entirely useless, however, as he was able to construct a pit dwelling to shield himself and his brothers from the cold during winter, though it required Rose to reconstruct it slightly to actually be inhabitable.

After the three had successfully created a sustainable society, Kamakura decided to create the nation of Tempura to appease he and his brothers' boredom, declared himself to be its king and ordered his brothers to assist him in conquering new territory for it. After successfully conquering a substantial amount of land, however, Kamakura was betrayed by his two brothers, who had grown tired of following his tyrannical rule, causing them to enter into a civil war with each other. Despite losing a substantial portion of his power during this period, Kamakura took advantage of the fatigue that had developed in the hearts of the Kurupistonians throughout the war by declaring himself to be a god who would be able to bring them relief if they served him, restoring himself to power in the process.

Kamakura once again lost most of his power within Sushi Tempura Nation following the massive scientific innovations that were brought to it through westernization. As more and more Kurupistonians began to become enamored with science and technology, they lost interest in believing in Kamakura and stopped believing in him as a god. Enraged by his loss of power, Kamakura became distrustful of the new technology and began destroying it at any opportunity he could. This resistance to change did not last, however, as Kamakura eventually became as overtaken with a desire to watch moe anime as the rest of his species, going so far to make a declaration that all non-moe characters be removed from television, and lost any interest in doing anything else.

While it is presumed that Kamakura and his brothers perished alongside the rest of their race during their planet's destruction, as they are not explicitly shown during the destruction, their fate is currently unknown.

Personality and Appearance
Kamakura is a medium-sized purple Kurupistonian. Despite referring to himself as a ninja, he wears a face-obscuring black samurai mask at all times.

The self-styled leader of the Kurupis brothers, Kamakura is both incredibly selfish and bossy. He generally does very little work for himself and instead expects others to wait on him hand and foot. He is also very childish, and is prone to throwing temper tantrums when he doesn't get his way, causing him to be seen as a major annoyance to both of his brothers, particularly Rose.

Along with being selfish and lazy, Kamakura is also very conniving, manipulative and ambitious, taking advantage of the boredom brought on by peace and the stress brought on by war to elevate himself to the position of king and god, respectively. He is shown to be a tyrannical ruler as well as a warmonger, forcing his nation into entering various national conflicts for his own benefit.

Kamakura is shown to be very old-fashioned, and dislikes the massive changes brought to his nation by both westernization and industrialization. Whenever Rose would obtain a newly developed invention from one of the many factories that began to appear across Kurupiston, Kamakura would immediately destroy it. Despite this, Kamakura eventually grew to develop the same obsession with moe anime as the rest of his people, showing that even the most stuck in their ways individuals were vulnerable to its addictive effects.

Kamakura has a close-yet-dysfunctional relationship with both of his brothers. In particular, he shares a fierce sibling rivalry with Rose, who frequently questions his decisions. Kamakura disliked the ease at which Rose embraced technology, to the point of declaring him to be an agent of evil after he purchased a television. Kamakura's relationship with his other brother Santos is considerably better, as the two would often play together during their early days while Rose worked, though they were still prone to fighting with each other. After both became obsessed with moe anime, Kamakura and Santos would often get into arguments over which characters from various anime series were better.

Abilities
Though Kamakura refers to himself as a ninja, he does not display any of the abilities associated with one, and is infact very loud and unsubtle. Despite this, he appears to be a competent fighter, as he was able to lead a war campaign to conquer the territories that neighbored his own. When testing out the powers of the evasive daruma item, Kamakura uses three different ranged techniques known as the "Ninja Beam Rifle", the "Ninja Fin Funnel" and the "Ninja Mega Beam Cannon". While all three attacks are shown to be quite powerful, Rose notes that none of them have anything to do with being a ninja.

Along his skills as a fighter, Kamakura is a very persuasive speaker who was able to manipulate both his brothers and the other Kurupistonians into following him as both a king and a god at various points throughout Kurupistons history. As technology began to overtake the lifestyles of his brethren, however, Kamakura was unable to further persuade others, causing him to quickly lose his power as a leader.

Trivia

 * His name and occupation, like both of his brothers, is shared with one of the three playable characters of the infamous kusoge Trio the Punch - Never Forget Me..., in his case Kamakura-kun the ninja. Like his namesake, Kamakura always wears a samurai mask despite being referred to as a ninja.
 * Kamakura, as a ninja, a warrior closely associated with Japan, seems to be used to symbolize traditional Japanese values. This is supported by Tempura Nation, which he is initially the leader of, closely resembling Japan, as well as the fact that he steadily begins to lose his hold over the nation as it begins to embrace westernization.
