Seriously.  What is this?

It’s from a movie called Prefectural Earth Defense Force (1986). From Toho Kingdom:

In this OAV release, a number of kaiju references can be seen. The first episode includes a blink-and-you’ll-miss-it shot of Godzilla’s shadowy nighttime profile against the city, as well as a shot of a Godzilla toy amidst a great deal of wreckage. In the third episode, Mechagodzilla is mentioned in passing. But the most spectacular sighting takes place in the second episode, in which the villainous Lady Baradagi poses as a sexy high school student to seduce a teacher in order to get information on the titular PEDF. When the teacher asks about Baradagi’s parents, she states: “A long time ago in Haneda, they apparently ate a flare and passed on.” At this point, an animated b&w recreation of the climax from Varan is shown, complete with a scene of the monster consuming the lethal flare.

So it looks like I better try and track it down…
