Koon Eduan (쿤 에드안, Koon Edeuahn, Kun Edan) is a High Ranker, currently in the 6th ranking. He is the head of the Koon Family, one of the 10 Great Families, and also the father of numerous children from the Koon Family, such as Koon Aguero Agnis.
His sobriquet Marlin (청새치, cheongsaechi; literally "Blue swordfish", in English "marlin") was given due to his enormous spear called Mago, which if decompressed, it's said it could pierce half of the Tower.
His other sobriquet is Blue Thunderclap (푸른 진격, pureun jingyeok, 震擊, zhèn jī; literally "Blue Thunder/Quake Strike" or "Blue Lightning Strike") because of the property of the Shinsoo he controls; the Shinsoo he controls is very fast and has tremendous electrical power. There were a lot of opinions that his sobriquet should be the Electric Eel because of this property, but Koon Eduan directly showed refusal, threatening he would "kill everyone who called him an eel".
Appearance and Personality
While his current appearance may be a little bit inaccurate due to seeing him as a data of himself on the Hidden Floor and not his current self, we can still get a pretty good idea of how he looks like in the present. Eduan, being the head of the Koon Family, is the one and only source of the typical traits that the family has, such as having blue hair and eyes and having a pale skin. He has long hair and his eyes sometimes varies in color while still being in a blue shade, at intervals they can have a light-blue color and at other times they can a purplish color. Eduan is known for his magnanimous personality and taking delight in fighting. He is also extremely proud and self-confident but is also honorable.
Koon Eduan is famous for his lewdness and he is the man with the most wives of the 10 Family Heads. He has a lot of children, so there is a lot of veiled competition among his children in the family; too much competition has created the 'official' fights. It is held once a year, with the following rule: 'When the children of Koon reach the age of 10, they are to fight each other. The winners are recognised as the true children and are allowed to wear the crest of the family, but the losers become the 'abandoned' and do not get the crest'. Although the fights are inhumane and bloody, Eduan himself says he's "not very interested".
