Well, first thing is you don't "transition" to kino. You should be touching the girls from the second you walk over. As you're opening, you should touch one or more of the girls on the shoulder OR on the small of their back. Very subtle and quick just to get the touching started. You want to come off as just a guy who naturally touches people. If you don't touch at first and then after awhile you start touching, it can be weird.
As far as demonstrating interest, you do that by qualifying and by using statements of intent.
You can qualify the girl by getting her to volunteer info about herself and then showing interest in her about those things
OR
you can just throw out a statement of intent like
"You're adorable. I don't like it
"Either way, the way to show interest without "putting them on the defense" is to follow up you interest with a tease. That's why I say shit like "I dont like it" or "ughh get away from me!" or "This is terrible" or "Too bad you're such a dork" or whatever, of course all in joking, playful manners, so they don't actually think I don't like it.
But, the tease is something you don't always need. You only really need it if the girl gets uncomfortable. If you tell a girl you like her and she's like "OMG, I think you're adorable too!" or some shit like that then DON'T tease her.
But, for the most part, you should throw in a quick little tease right after a statement of intent just to be sure.
