The table was moved a bit.

The guests that came arranged the seats to the side to sit and watch. They suggested that they could do this outside, even though most of them didn't know why they are doing this. Bloody Chariot however, didn't even move an inch.

He just sat there calmly, waiting for the match.

The first suspect, let's just call him Suspect-1 stepped up and his opponent is a senior who wields a sword. 

*SWOOSH*

The battle began with the swing of a sword.

*BANG* *CLANG*

The clashing of metal. The collision between the spear and the blade rung like a bell in that closed room. Everyone is watching the match intently.

The second elder who obviously had more experience explained.
