Matsuri Kiritani, running on a beach, naked, in slow motion. It’s like a masterclass in Gainaxing. The Bluray is basically an animated photoshoot with terrible lighting, auto-white-balance, and cheaply-licensed music, but her personality shines through, and you occasionally get to hear her voice.
And, yes, I know, video or it didn’t happen (NSFW). The Bluray is no longer available on Amazon Japan, but the title is “Matsuri5 らぶりー☆とらべるらばーず” (“Lovely Travel Lovers”), and a quick search turned up a streaming site (set pop-up ad-blocker to stun).

(plenty of pics here and here, with the usual warnings about NSFW and disabling Javascript)
The gold standard for this sort of nekkid cheesecake video was Playboy Video Centerfolds, which were usually stuffed with personality. And since I met most of the women who were featured in these, I can confirm that they were really like that. A lot of Playboy’s other videos were more contrived, with little regard for the women as more than posing dummies, but the video centerfolds really humanized them. Matsuri would have made a terrific Playmate if she’d been born twenty years earlier.
(most of the video centerfolds were never released on DVD, and could only be seen by buying VHS tapes directly from Playboy; some of them were also aired on Playboy’s cable/satellite channel, back in the days when it had something to do with Playboy)
