This is what happens when a children's detective shaped like a rear end gets handed the keys to an NHK science documentary and nobody in the building stops it. Cosmic Front is a real program, the kind that treats deep space with a hushed voice and a slow zoom, and here it is feeding the Butt Detective the newest findings on dinosaur research and rocket engineering while he works a case. Mikku carries the facts, so the mystery beats and the lecture beats split the runtime without either one apologizing for the other. Two episodes, no dread, no stakes that will follow you to bed. Watch it the way you would sit through a planetarium show at eleven at night: warm, unhurried, quietly delighted that somebody decided a polite gentleman sleuth with a butt for a face was the correct host for actual science.

The Butt Detective takes on a new case, and Mikku lends a hand in cracking it. These two specials are an educational crossover between Oshiri Tantei and the documentary program Cosmic Front, so alongside the sleuthing they pass on up-to-date findings from dinosaur research and the latest on space rockets. Expect a comedic mystery with a bit of fantasy, where solving the puzzle and learning some real science share the screen in equal measure.
