[If one were expecting the crowd to run away in terror... It's quite the opposite! In fact, the audience (except Kotarou) was getting hyped. They were getting pumped and cheering along as Nobunaga continued to sing along. This was the first time that Kotarou ever felt like he stepped into a concert. They're so encouraged by Nobunaga's singing that they begin to slam their pickaxes into the stone walls! They were actually getting more motivated to work.

"I wanna be tied up! and "I'll become a masochist for his sake!" and "I don't know who this man is, but I'll follow him to the depths of Hell and then some!"

Someone had to play straightman here, so it had to be Kotarou. He knew that he was a small tiny speck compared to most people, but this was ridiculous!]

WAIT WHAT?! WHEN DID WE GO FROM OPERA TO HEAVY METAL!? AREN'T WE CHANGING GENRES TOO FAST?!

[He sounds like his manager now... Kotarou points his pickaxe at Nobunaga.]

Hey, hey! Don't go turn people into perverted things, okay?! We gotta keep some order around here!
