Khun Hachuling

Hachuling (하츨링, Hahcheulling, Hachling, "Hachuling") is a Ranker, a defected member of the Koon Family, and Koon Agero Agnis' older brother. He may be biologically related to Agero but they don't share the same mother.

He is a member of the Walhaiksong, a non-government organisation and claims that since joining the organisation, he has separated himself from his birth family.

He is shown to be able to hack into Koon's Lighthouse (supposedly a difficult feat to pull off) and he controls Lighthouses with some kind of gaming console. Take note that hacking into a Lighthouse is unlikely a scout ability, but the ability of someone very good with technology.

In Part II, he has shown up as an owner of an arcade. After betting Quant out of all his money through games, Lero-Ro challenges him after finding out his identity.

Notes and Trivia

 * Although fans originally speculated that he was a Light Bearer seeing how he hacked into Koon's Lighthouse, SIU has stated that he is actually a scout, and it can be assumed the hacking is simply a skill he utilizes against enemy Light Bearers.
 * It is debated whether he is a Ranker or a High Ranker. Although it is not explicitly stated, one could be lenient to the concept of High Rankership since he is a member of Walhaiksong.
