Who knows how long he was a slave? Though he's listed as a pacifist, so was Uchiha Itachi, and I don't think you need an elaboration on his power.

What I'm getting at is, it isn't mentioned how early he was imprisoned, it only states that once he had reached the cells, he was there alongside Kimimaro. He could have been aged 25 by then, which is above the average age promotion of a jonin. The camouflage being an A-Rank technique, though not really as complicated as the rasengan or chidori, (of course), perhaps it was taught to him by one of his fellow villagers?

Perhaps another shinobi from kirigakure defected, (I mean who wouldn't? After all it had been labeled the bloody mist) using a similar method that Hikaru would use in the future. So now we have that this whole strategy was more thoroughly planned, by having had Hikaru's 'sensei' if you will, share his background story.

Conclusion from all that rambling: '''A shinobi who had knowledge of the hiding with the camouflage technique defected from Kirigakure, fearful of it's citizens, such as Zabuza who had killed his entire graduating class. As the Kaguya are stated to have lived on the outskirts of Kirigakure, on the home page itself, it is highly likely he would come upon their territory. Now, we don't know if that village was entirely Kaguya, though this man settled there, and at some point, Hikaru became his student, thus learning the camo technique.
