Ryoutsu stumbles into his most absurd case yet when a shadowy ninja organization threatens to steal a legendary golden treasure hidden beneath a recreated Edo-period fortress. Armed with nothing but his comedic confidence and questionable detective skills, he recruits an unlikely team of allies to stop the thieves before they strike. What unfolds is a chaotic blend of slapstick action and period-piece parody as Ryoutsu bumbles through ninja combat, over-the-top traps, and historical references that nobody asked for. The special thrives on its willingness to derail its own plot with ridiculous tangents and character shenanigans. Between dodging shuriken and accidentally triggering bizarre mechanisms, Ryoutsu proves that sometimes the worst detective makes the best entertainment. Viewers who thrive on absurdist humor and don't mind their action sequences interrupted by pure nonsense will find this a perfect time capsule of the series' comedic sensibility at its most unhinged.
