Just completed my first exam. T'was not bad. Two more to go, be back by Friday.

The "Elimination Squad" that Ren in included in is infamous even within the Jahad Family ("렌이 소속되어 있는 '처단부대'는 자하드가 내에서도 악명이 높습니다.") [출처] 68화 후기 | 작성자SIU Yeah so now that I read over it carefully, you were right that in that it seems this squad is part of the Jahad family in a way. However, in Korean context, it can also be used to say that they are just loyal to the Jahad family, hence they are always on their side. This is similar to the Edroks that serve as Guides for the Jahad family. If the Elimination Squad members are Jahad, so are the Edroks. You could say it's sort of like they were accepted into the family.

SIU states that most of the Elimination Squad's enemies are "people who were once Jahad Family as well" so even the Jahads bear a feeling of rejection towards the squad.

So for now, it's left quite ambiguous. It's either

1) All 10 Familiies count as Jahad Family (as in on their side, not literal family)

2) You join the Jahad family when you present complete loyalty to them.

Either way, it's something like a term that does not exist in English, I would say. Obviously these guys are not Jahad's blood family, but at the same time I wouldn't say they were adopted like the princesses. Something else... sorta like joining an organization, more of.
