Just started Kiwami

Sup guys, just started Kiwami after playing 0 first. I'm actually liking Kiwami more because I feel I know the characters more after 0, I was a little bit skeptical of getting Kiwami since I heard it wasn't as good as 0, but man I am loving this game, unfortunately I Heard it's too short, I'm on chapter 6 and about 8 hours in.

I plan on getting yakuza Kiwami 2 but I'm worried about skipping 3, 4 and 5, is it possible to jump from Kiwami 2 to yakuza 6? Or do you guys recommend to play 3, 4 and 5? Thanks guys.
