Khun Aguero Agnis

Koon Agero Agnis is the son of Koon Eduan, the current head of the Koon family, though he is referred to as Mr. Koon. He was expelled from the family because his older sister failed to become one of Jahad's Princesses. He teamed up with Baam and Rak and passed multiple tests with them. He was assigned the Light Bearer position and was awarded Best Seed. He is highly intellectual Regular, who has performed well on all of the tests so far.

Appearance & Personality
Agero has white hair and navy blue eyes. He wears a bandana tucked inside his hair, in some occasions he has removed it and tied his hair with it, the significance of the bandana is not known. He wears a white shirt and black tie, and carries a briefcase.

He is depicted in the series as a cool-headed and highly intellectual character, often the schemer of the group. He is also rather smug when his plans work. He was able to amaze even the Rankers with his planning during the hide-and-seek game, and has been described as "a dangerous being". He is skilled in the manipulation of other, and has the mindset of "a ruler". He is rather friendly most of the time, but can be extremely ruthless. He can also be rather playful while toying with others and it is subjective whether this trait is due to his age or his personality.

History
Not much of Koon's history is known, other than that he is a member of the Koon family and that he was expelled due to the failure of one of his older sisters to become a Jahad's Princess.

It is hinted that he cared deeply about Maria who he helped to occupy a position once held by his older biological sister. He helped Maria because she cared for people and because he thought that she deserved to be happy.

Relationships
Baam: When Koon met Baam, he tried to become friends with him because he thought he might be useful. Since then he seems to have bonded with Baam a bit, athough with Koon you never know...

Rak: Koon is often annoyed by Rak, although he seems to have come to appreciate him a bit. However, he often makes snide comments about him.

Hatsu: Relations between Koon and Hatsu were frosty at best, but Baam helped them get to know each other.

Lahel: Koon met with Lahel after the Crown Game and has promised to not reveal her identity to Baam.

Powers and Abilities
Speed and Agility: Koon is a trained fighter, and has demonstrated excellent physical skills.

Briefcase: Koon's briefcase Manbarondenna has an insane number of functions, including: Lighthouse Control: Koon is good at moving and using lighthouses.
 * Toughness: It can resist knife blows, bullets, and more, nothing has yet been seen to damage it. Koon uses it as both a shield and a weapon.
 * Pocket Dimension: The briefcase can hold large amounts of objects inside it easily. It can even suck up enemies.
 * Cloning: The bag can make copies of any non-alive object placed inside. There are still material that cannot be copied. (Most material in 2nd Floor cannot be copied.)
 * Elasticity: The handle can stretch huge lengths.

Perception and formulating strategies: Koon is the mastermind of all sorts of tricks. He can often see through other people's strategies and make the best plan to exploit the enemies' weakness. In the Hide-and-seek test for team A, Koon delibrately used Quant's irritable nature and hasty judgement against Quant. Even more brilliantly, Koon secretly helped Quant to defeat his own team in order to ensure the maximum number of Koon's "real friends" pass the test.

Plot Summary
Koon began on the second floor with the other Regulars. He found a few allies during the first test and stored them in his briefcase. He ran into a large red regular, and asked him if he wanted to become an ally. The regular remarked that trying to find allies was stupid as the test was all about killing each other, to which Koon replied that finding allies was important, and was part of the "mindset of a ruler". He stated that the regular was not even fit to be ruled, and promptly defeated him. He then encountered Baam, and after talked to him for a while before decided he was useless, prepared to move on, when they were attacked by Rak. He and Baam hid behind a rock from Rak while trying to decide what to do about their situation. Koon noticed that Baam had the Black March, and decided that if Baam posessed such a weapon he was probably special, and could make a useful ally. He introduced himself to Baam while Rak continued to rage at them on the other side of the rock. It was then announced that they had to find a teammate, and he and Baam were left with no option other than to grab Rak, which upon failing to secure his cooperation they did. Paired with Rak and Baam, Koon managed to get through the barrier test easily. He had difficulty figuring out Yu Han Sung's door test, as he was focused to hard on the "clues", but was saved when Rak simply kicked open a door.. He played the Crown Game with his team, and he and Rak easily demolished most of the other teams using their fighting skills. He took a break in the middle and let the allies he had been storing in the suitcase loose to fight for them. The later opponents were more skilled, but they still looked like they were going to win. However, when Baam jumped off the throne to protect Lahel they lost.

Koon was then assigned the Light Bearer position and seeded first. He did well in the classes (although he commented that they were boring), and with Baam's help managed to collect a list of "friends". He was then placed on Team A for the Hide and Seek game. He masterminded the whole team expertly in an attempt to capture Quant, but the attempt failed making Quant feel overconfident just as Koon wanted. He then moved to the second part of his plan to help his team's It escape. He confronted Quant, and tried to make him think that Anak was in his briefcase, while really she was riding one of his lighthouses. Quant figured this out and tried to foil the plan by pushing Koon off a cliff, but it was then revealed that Koon had planed for that as well and had set up a pulley system attached to the light house Anak was on. Anak was carried up to the exit while Koon was saved. However, afterwards a member of Koon's team blasted Quant up to Anak, and he was able to catch her.

Afterwards Hide and Seek game, Koon appeared to lament his failure with his team, but it was then revealed that he was actually planning to get his list of "friends" through the test, and that he had made a deal to help Quant catch Anak, in order to facilitate things for his "friends" on the other team.
