Oh hell na, what are those deals, bro? Kintaro, please reconsider. This episode is all about uncovering the mystery of the beast, just as the title suggests. They also introduced a new character. How will he fit in? Can he adapt to the workplace? We'll see in the next episode. I gotta say it again, they animated the Bullbuster really well. It always amazes me. This episode is crucial as the starting point of their research into the beast. Definitely a must watch.
