No just them but he also knew Hanto. Hanto took part time job at the curry house where he met Miki. And Miki also knew Bouken's menor (IDK his name) in the same place.
Always a sad day when a good Tokusatsu actor dies. I enjoyed his work in what little of Abaranger and his work in the team-up with Dekaranger. He'll be missed.
If there is, it'll probably be an accident. The movie was filmed long before his death (though not long enough :redface2. It'll probably mention the Dino Curry House again.
