Special episode of Tian Guan Ci Fu.

Koro-sensei reminisces about his first meeting with Karasuma, where they first butted heads and fought against each other, ultimately coming to respect one another. However, Karasuma eventually points out their actual meeting wasn't nearly as eventful.

In a world where half-human, half-animal chimeras live and work alongside normal people, there are sure to be a few bad apples in the bunch. Unfortunately, half-human criminals means non-human clues that often leave the police stumped. That's where lone wolf detectives like Hiroshi Inaba come in. He's literally part wolf and has the amazing ability to extract critical information just by examining or tasting a sample of someone's hair! Of course, that ability has also resulted in Inaba having a little bit of a hair fetish, but that doesn't seem to be a problem for his two assistants. (Well, at least the cross-dressing one isn't complaining much.) And it's nothing compared to the strange tastes of Inaba's nemesis, the omnivorous (and half goat) crime boss Don Valentino, who has an appetite for green legal tender instead of tender young greens! Inaba's sworn to cut Valentino out of the criminal flock before the Don can wolf down more ill-gotten dough, but he's going to have to chew his way through a lot of evidence to get his goat. Can sheer dogged detective work put the baaaaad guys behind bars? (Source: Sentai Filmworks)

The village of Ootsuka—home to Shino Inuzuka, Sousuke Inukawa, and Hamaji—was lit on fire under the preconception that a virus had seen all of its life eradicated. Now surrounded by flames and on the verge of death, the three were approached by a strange man holding a sword. He tells them that they must reach a decision if they want to live. That night changed everything for these children. Five years later, the family of three now lives under the watchful eye of the small Imperial Church in a nearby village. All is fine and dandy until the Church attempts to reclaim the demonic sword of Murasame. To accomplish this, they kidnap Hamaji to lure Shino, now a bearer of Murasame's soul, and Sousuke, who possesses the ability to transform into a dog. The brothers must put their differences aside to rescue their beloved sister from the Church in the Imperial Capital, signalling the beginning of a very difficult journey.
