Hello there, as we all know and have read many articles about who does ended up with Kagura; we know nothing about it. But when you watch Season 1:Episode 42 and Episode 43. You can conclude that Gintoki and Kagura like each other(romantic love). We all cannot deny it based on what they say. In Episode 42, yes we could say that maybe Gintoki was just poking Kagura's father. But in Episode 43, notice how Kagura reacts when the characters inside the shop talks about Gintoki having a relationship with some other women. Having noticed and said all of it, alongside with the show, I could say that the creator hides those kind of things for us to find it for ourselves. :)
