Aaaaah.
It's more complex than just that. While, yes, in essense you're basically correct, the sitaution gets _MORE_ complex when you factor in a ronin by situation or choice.
(Techically, according to the strictest view of the tradtions on Clan, right now Naruto is a ronin.)
Since Kyo and Ya-chan are ronin by choice, and in fact, the way Kyo did it as I understand isn't quite the tradtional method (Ya's was, btw) of doing so.
They can be (with the noted insult POSSIBLITY!) adopted. Situational ronin (Naruto in theory, a good example would be Sasuke, pre leaving) can be easily, but tradionally only done to a sept or a allied clan, who have the name as well. Honeslty, most cases of sole surivors, is they're 'guardian'ed' not adopted.
A lot of can a ronin by choice be adopted boils down to three things.
1. why they left. Kyo... grey area, and in fact, I'd say he'd be not elgible for adoption and or readmittance back into his clan, depends on how active the declaration was, unless there was some overriding reason. Ya-chan? She's acutally a case example of someone who -can- be readopted by her former clan, but not adopted without permission from that clan.
Hurm. Other ronin by choice ... *shakes head* No real clear example, mind you.
In Naruto, really.
2. The way they left. Kyo (since I can't recall offhand if Fosfor said in thread, so I'm not saying WHY)'s declaring himself ronin was actually a BIG, BIG, BIG time insult to his family. There would have to be a major reason for that to be overriden. Ya-chan did it publically, but that was pretty much WITH the Hyugga at the time's blessing. So... toss up there.
3. Sitaution of the clan that's adopting them, or their old clan.
Aaaah.... this is where situational needs can outrump insults.
*shrugs* It gets complex. There's no hard and fast answer, and it changes often on the ronin in question. Some ronin-by-choice, did it to escape (aka the R1/2 serinaro) a situation where there was no real way out, but felt that she or he shouldn't answer for the situation. (Or rightfully SHOULD not have to answer for it, in fact)
They are often the most frequenlty adopted into other clans, but that's only for really... unusual ronins, really. Ranma... 50/50, and it'd be more than likey marriage adoption than child adoption. Honor loss, but not significant, and cleans the slate of the ronin. (In fact, in some cases it's a honor GAIN for the adopting clan... but...)
Ronin by choice (Kyo) who are doing it to disavow what their parents want(as long as it's a honorable wish)?
Scum. Worthless, not a fucking chance in hell, and never adopted period, though their old clan might take them back if they agree to do what the parents want... and how publically the ronin going was. Adoption by other clans... would dishonor the adopting clan BIG time. And yes, this is where blood insult level MAY be reached.
Ronin before they got disowned (Ya-chan)... depends why. In her case, she'd be eglible now for readoption by the Hyuuga, and yes, they'd consdier it a insult if she was by anyone else. BLood insult level... not as much, but it's still there.
*shrugs* It's complex.
Really.
A.
. Which would call for those handy collapsible spoiler tags other forums have. I can't think of a better solution, well aside from editing the quote out once the main post changes. Or a pastebin, though I'm not sure how Fosfor feels about having his stuff posted outside of the forum.
