It is actually ironic cause in the second movie cosmos vs justice , cosmos made his decision by making musashi his permanent human partner/ host and yeah they bonded forever....
I love it how people think that uploaders can pull subtitles out of their ass like a magic trick. Saga I don't think has been subbed yet, and a lot of subtitlers are busy lately with a pesky thing called life. Or short handed because despite all the language speakers and people with computer know how they're still short handed. FY has done Super 8 brothers and you can find it on youtube, HK also has done it which thankfully I haven't seen on youtube.
