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, which if decompressed, it's said it could pierce half of the Tower.[1]

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.[1] 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".[1]

Personality and Appearance

Eduan is known for magnanimous personality and taking delight in fighting.[1] He is also extremely proud and self-confident, but is also honourable.


Koon symbol

Symbol of the Koon Family

Koon Eduan is famous for his lewdness and he is the man with the most wives of the 10 Family Heads.[1] 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.[1] 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'.[1] Although the fights are inhumane and bloody, Eduan himself says he's "not very interested".[1]

Powers and Abilities

Before Enryu appeared, Eduan was considered the strongest Spear Bearer in history. The name of his spear is Mago and when it is ignited its compression rank increases to an abnormally high figure.[1] Also, the Shinsoo he controls is very fast and has tremendous electrical power.[1] It is said that when partnered with Hendo Lok Bloodmadder, they formed an invincible team.

Notes and Trivia

  • One of his daughters, Koon Maschenny Zahard, is the owner of the Yellow May and is the only Princess in the family who has been awarded one of the 13 Month Series.[1]
  • It has been stated that Maschenny is Eduan's favourite daughter and child.[citation needed]
  • Koon Eduan had prepared a special test with a shocking condition, which is 'Whoever fights him and wins is given everything from the family', but none of the Regulars have survived the test so far.[1]
  • He is remarked to wish to fight Urek Mazino, as he was the man who pushed him out of the Top 5 Rankers.
  • His Sobriquet can be translated into "Blue Advance".
  • He is famed as a collector of a multitude of the highest ranking items in the Tower, as he values his collections very highly. This is evidenced by the shock the administrators have on the Floor of Test after Yu Han Sung explains Koon Aguero Agnis had plundered his father's "treasure house" before coming to the Tower, taking such amazing items as Manbarondenna "the entertaining and amazing magical cloning bag" and a high-grade suspendium pulley. [2]
  • He is friendly with Arie Hon despite their families are rivals, but resents him a bit for being ranked higher.[3]
