I was thinking that Japanese jazz fusion you'd hear in something like Capcom games in the 90s or Mighty Orbots for DRGN, maybe with a little bit more rock or orchestra to give it a bit more of a Sentai or fantasy vibe. The six main heroes would definitely have those lyrical themes you here in anime and Kamen rider that play when ever they do a cool action scene.
For edible!e green tea, probably something that sounds like a cross between the jazz you'd hear in Peanuts specials, and the quirky trip hop of the Gorillaz.
