Khun Hachuling

Hachuling is a Ranker, a former 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 has been referred to as Hachuling by one of his companions but it is unclear if this is a nickname or his real name.

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 pretty 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 is likely, the ability of someone very good with technology.

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.
