It´s been so long: Did the manga show Guts and Puk as a duo right when we saw them first, or did it explain how Puk and Guts met?

Flashbacks like these are dangerous. They can be dangerous. Flashbacks ruined Naruto. In this case, I hope Miura doesn´t ruin Gut´s image as the "unchosen", the guy that fights destiny by sheer will power. It would suck if we find out that Guts had some events in his past as kid where he managed to connect to the more fantastic aspects of what would become part of his future life.

Despite these worries, I´m enjoying this flashback. Even though it means the wait for the main plot continues ...
